What are the precautions when spraying boron fertilizer during the flowering period of planting pepp

2-3 kg of superphosphate, 10 kg of plant ash. After fertilizing, hoe and water immediately. At this point, the plant is close to ridge sealing.

At this stage, in terms of temperature control, the temperature is 21-26 degrees during the day, and it is appropriate not lower than 15 degrees at night. Before the minimum outside temperature drops to close to 0 at night, a temporary small arch should be immediately deducted for cold protection and insulation. If it is too late to buckle the small arch shed, you can use plastic film to cover the pepper tree with another layer to avoid freezing the plant and ensure the growth of young fruits.

The management of pepper after entering the flowering period is particularly important at noon on a sunny day, and the main purpose of this stage of management is to promote flowering, flower preservation, and promote fruit set.

<> growers should scientifically and appropriately control the temperature, humidity, light, water and fertilizer and other conditions of the planting plot, with sparse flowers and fruits, pepper growth, when this disease occurs, the phenomenon of pepper plant stems is thin and very long, the internodes are also relatively long, and the leaf color is light, resulting in reduced flowering. The main reason is that the fertilizer water is too large, especially the nitrogen fertilizer is applied too much, and the production should not only prevent the small leaf area of the pepper from causing "falling seedlings" when it sits, but also prevent the growth of the plant from growing too vigorously to form "crazy seedlings".

In the process of pepper planting, the plant is in the growth and development stage, and the demand for phosphate fertilizer and potassium fertilizer is higher. Especially in the flowering and fruiting period, we should pay attention to the combined application of calcium phosphate, urea, potassium phosphate and other fertilizers. In the early stage of pepper growth, it is not suitable to chase the humid environment in the shed during the pollination period, which can increase the adhesion of the stigma, which is conducive to the germination of pollen tubes and the completion of fertilization.

Pepper stubble can last for about a week, and during this time, it is necessary to keep the environment in the shed moist between 8 and 11 a.m. to improve the pollination rate. There are many varieties of chili peppers, and before planting, we need to fully consider the habits of consumers, as well as economic benefits and our own environmental conditions to choose the right pepper to grow.

Appropriate supplementation of chelated boron fertilizers.

Boron fertilizer is a trace element, and it is recommended to spray 3 to 5 times during the growing period of pepper, and it cannot be used excessively. You can choose the formula: potassium dihydrogen phosphate + boron fertilizer + tridecanol foliar spray.

2.Control Wangchang.

If the pepper plant grows vigorously, it will lead to falling flowers, and the growth can be regulated with conditioning agents such as love more harvest and mequatin.

3.Watering wisely.

Pepper belongs to the crops that like moisture, fear of drought and waterlogging, in the case of the soil is not particularly arid, pepper is tried not to water, especially watering, if watering too much often causes root rot, bacterial wilt and other diseases, but also causes the plant to grow, pepper later flower and fruit drop;If the soil is too dry and not watered, it will not be conducive to the absorption of nutrients in pepper, which will cause slow growth of pepper, affect the flower bud differentiation and pollination of pepper, and also cause flower and fruit drop.

4.Advance the medicine.

Before the pepper flowering, it can be sprayed with 5% chlorothalonil dust agent + 100 times the new high-fat film, once every 7 days, 2-3 times in a row to prevent the harm of diseases and insects. It can also be sprayed with pepper Zhuang Ti Ling before flowering to prevent flower and fruit dropping.

It is recommended to water peppers in the morning during the flowering period and keep them moist to improve pollination.

The main thing is that attention should be paid to the yield of some peppers, and also to the nutrients of peppers, and attention should be paid to frequent watering, and attention should be paid to some pests and diseases, these characteristics should be worth noting.

Spray all the roots of the peppers evenly, but not too much, the humidity is fine, and let them ensure sufficient sunlight, and then cooperate with the absorption of water to grow well.

Boron fertilizer must be used 1-2 weeks before flowering, or boron fertilizer can be drip irrigation at the root, and the two-pronged approach ensures that the pepper flowering and pollination are normal, the fruit-bearing ability is strong, and the probability of high yield will be greatly increased.

First of all, don't choose noon when spraying, and be sure to add the right amount of water, but also do a good job of blending, and don't spray too much at one time.

The excessive amount of chemical fertilizer is mainly due to the excessive amount of nitrogen fertilizer, which causes the concentration of solution in the soil to be higher than the concentration of cell sap of the root, the root system can not absorb water normally, and the plant is wilted due to water deficiency. Spray the plants with brassin. Brassin is a new type of growth regulator, which can improve the stress resistance of crops and effectively alleviate the impact of fertilizer damage.

When spraying, 5 ml mixed with 30 kg of water is sprayed. The performance of green pepper seedlings will have yellowing of leaves, curled edges, gradual yellowing of leaf tips, yellowing of stems, stunted plant growth, and serious will cause growth to stop.

Soil dryness When the soil moisture content is less than 10%, when compound fertilizer and nitrogen fertilizer are applied, due to the sudden increase in fertilizer components in the soil, the concentration of solution in the soil increases in the process of decomposition and thawing, and the root cells infiltrate water in the reverse soil, resulting in the root system can not absorb whether it is the burning of seedlings caused by farm fertilizer or chemical fertilizer. If too much fertilization at one time, uneven fertilization, or insufficient water supply after fertilization, it will lead to an increase in the concentration of soil solution or local soil solution, causing root water backflow, resulting in root water loss and root burning. The concentration of fertilizer in the soil is too large.

If too much fertilization at one time, uneven fertilization, or insufficient water supply after fertilization, it will lead to an increase in the concentration of soil solution or local soil solution, causing root water backflow, resulting in root water loss and root burning. The most effective and direct way is to water the fertilizer quickly, let the fertilizer fully dissolve, dilute the concentration of the fertilizer, and then spray the foliar magnesium to adjust it. Dilute the fertilization concentration with water first, and then dilute it with an appropriate amount of rooting powder and water it again, so that most of it can be reversed.

Twenty-five milliliters of 0.1% trisanol (bucket water) and 5 grams of 20% naphthalene acetic acid (bucket water) are used in a two-way compound to activate the activity of pepper roots, promote pepper rooting, and strengthen the absorption of nutrients in the soil by pepper roots.

Improper fertilization of pepper will cause the veins of pepper leaves to change, which is easy to cause pepper diseases; When too much fertilizer is used, the plants will slowly wilt until they die; When foliar fertilizer is used in excess, growth is inhibited.

Seedling injury. When inadequately rotted organic fertilizer is applied in the seedbed and in large quantities, ammonium nitrogen is converted to nitrous nitrogen, and the pepper root system is damaged. Sometimes it also causes iron deficiency symptoms, yellowing of the central leaf, and a small number of seedlings. Too much ammonium nitrogen can also cause young leaves to shrink.

If the concentration of root fertilization is too large, it will cause plant wilting, and in severe cases, it will cause the death of pepper plants. When the amount of seed fertilizer is too large, there will also be the phenomenon of burning seedlings, and urea and other fertilizers cannot be used for seed dressing. In the process of planting peppers, growers do not rot the chicken manure, which is not only easy to cause disease nematodes, but also cause the plant to be burned.

This will not only reduce the survival rate of the peppers, but also reduce the yield of the peppers.

In pepper planting, urea is used very frequently, and it is favored by farmers because of its low dosage, fast fertilizer efficiency and moderate use. Therefore, some novice planters directly grab a handful of urea and put it in the pepper planting hole when planting peppers, and use it as base fertilizer. When applied in this way, it is often prone to two results:

First, the leaves of the transplanted pepper seedlings will slowly fall off, and after a period of time, it will slowly grow new leaf buds (which is less fertilized); Second, within a few days after transplanting, the pepper seedlings will die and dry up directly (which is more serious fertilizer damage);

According to relevant research results, the production of 2000kg of chili pepper requires the absorption of nitrogen, phosphorus and potassium. Experiments have confirmed that more nitrogen, potassium and phosphorus should be applied appropriately to fertilize peppers. Fertilization programs with more nitrogen, less potassium, and less phosphorus, higher yields than nitrogen, phosphorus, and potassium.

The scientific fertilization method should first measure the content of a variety of reasonable nutrients in the soil and calculate the nutrient content that the soil can provide; Then the nutrient content required to absorb a certain amount of chili pepper will be obtained, and the amount of soil available for supply will be reduced; Finally, according to the nutrient content of different chemical fertilizers and the utilization rate of absorbing eggplant, the amount of nitrogen, phosphorus and potassium fertilizer required was calculated. This is professional soil testing and formula fertilization. In areas where there is no standard soil ridge testing and there is little organic fertilizer, in order to increase the yield of pepper, it is recommended that 50-60kg of nitrogen, phosphorus and potassium compound fertilizer, about 50kg of calcium, magnesium and phosphorus fertilizer, 15-25kg of urea solution, 10-20kg of ammonium sulfate or sodium chloride (or 200kg of grass ash) should be applied to 1 mu.

The actual amount of fertilizer applied is adjusted according to the soil fertilizer efficiency.

Among them, calcium, magnesium and phosphorus fertilizers are late-acting, have poor mobility in the soil, and are easy to be fixed by the soil, so they should be all used as base fertilizers and applied intensively. Urea solution is easy to burn roots and easy to outflow, only a small amount (generally 5kg mu) as base fertilizer. Potassium fertilizer is also easy to outflow and tremble, and pepper absorbs potassium fertilizer during the fruiting period, and potassium fertilizer can promote the growth of fruits, so potassium fertilizer is mainly used as fertilizer in the fruiting period.

Compound fertilizer is mostly used as base fertilizer. If it is planted with plastic film mulching, more than 80% of the total yield is used as base fertilizer; 50 -60 cohesive soil with good fertilizer retention without agricultural mulch film is used as base fertilizer, and 30 -40 -40 sandy soil with leakage is used as base fertilizer.

In addition to nitrogen, phosphorus and potassium, chili peppers also require a variety of nutrients. The organic fertilizer of the farm is complete in nutrients and can also improve the soil, so it is good to plant peppers and apply farm fertilizer. There is no farm fertilizer, you can buy biological organic fertilizer, it contains the active bacteria have nitrogen fixation, phosphorus solution, potassium solution, that is, the free nitrogen in the air is fixed in the soil, the soil crops can not use phosphorus, potassium into a usable state, high fertilizer efficiency, no pollution, crop pests and diseases after application, yield and quality improvement, if the complete use of chemical fertilizer pepper, in addition to conventional fertilization, also need foliar fertilizer, mainly to supplement it needs boron, zinc, iron, copper and other trace elements, you can choose to use foliar fertilizer, spray 3 times, Generally, the output is increased by more than 15.

In the early stage of fruit setting, it is necessary to do a good job of preserving flowers and fruits to improve the flowering and fruiting rate of peppers. Fertilizers rich in various organic matter can be used to supplement the required nutrients in the middle and late stages, which has a significant effect on the low temperature and high temperature swelling of pepper fruits, which can not only protect the fruit and promote expansion, but also effectively improve the yield and quality of pepper, prolong the harvest period, and increase yield and income. The excess side branches of pepper should also be sorted out in time to avoid excessive nutrient consumption, and the side branches of the inner chamber and the side branches that block each other should be removed to prevent the epidemic of diseases caused by slow plant growth and poor ventilation and light transmission.

The mid-to-late stage management of pepper fruit set is a key period for fruit preservation and efficiency. After a long period of high or low temperature growth, some physiological functions of pepper plants begin to gradually decline.

Seedlings need a higher temperature, 25-30 degrees during the day and 15-18 degrees at night. Seedlings are not tolerant to low temperatures, pay attention to cold protection. Peppers at 35 degrees will drop flowers and fruits.

Chili peppers have strict requirements for conditional moisture. It is neither drought nor waterlogging tolerant and prefers dry air conditions. The fruit-setting period of peppers is from the end of the harvest period from the time the peppers sit at the door to the end of the harvest period.

The seed setting period is characterized by the simultaneous growth of seedlings and fruits, so it is necessary to take the management measures of fertilizing water to promote the balance of vegetative growth and reproductive growth, so as to prolong the seed setting period. Some pepper varieties have unlimited growth habits, and most of the fruits produced after the beginning of autumn cannot ripen red. Vigorous shoots tend to cause colony closure, affect fruit coloration and even rot, and also consume and compete for nutrients.

Therefore, the tips of the shoots in the canopy of plants should be destroyed in the late growth period.

According to the amount of basal fertilizer, look at the growth, early flowering, flowering, and fruit setting of peppers. Apply a little more and pour a little water frequently. From flowering to fruiting, chili peppers need a certain amount of nitrogen fertilizer to promote balanced growth of the plant, while from fruiting to maturity, it absorbs more potassium fertilizer.

Do a good job in the prevention and control of pests and diseases during the growth period of peppers. Chili peppers are neither drought nor waterlogg-resistant. During the flowering and fruiting period of peppers, the soil moisture should not be too large or too small, which is not conducive to the growth, flowering and fruiting of peppers.

If the grower irrigates a lot of water during the flowering and fruiting period of the pepper, the humidity is high, which leads to the overgrowth of the plant and the consumption of too many nutrients, and the nutrients of the pepper buds are insufficient, which will cause the pepper to fall flowers and fruits.

Peppers need to be fertilized when they bloom and bear fruit. In the flowering and fruiting period of pepper, urea, trisodium phosphate, potassium dihydrogen phosphate, foliar treasure, rare earth micro-fertilizer, etc., can be sprayed, which can protect flowers and promote fruits, improve yield and improve quality. In addition, the fast-acting fertilizer should be quickly applied 1-2 times in the young fruit stage of pepper, and it is generally diluted with 3-4 times of water in the manure of well-rotted people, so as to ensure that the plant is not defertilized and promote the rapid expansion of young fruits.

The application of phosphorus should be increased during the flowering period of pepper, because phosphorus can promote the transport of nutrients like flowers, and the effect of promoting flowers and fruit preservation is more prominent, which is helpful for the yield improvement in the later stage.

The need for fertilizers is different in different periods; Properly water each fertilization application. <>

Peppers should be watered after planting. This time the watering amount is relatively large. Because the soil is soft because the soil is soft because of the base fertilizer applied to the pepper planting soil at this time, there will be no root problem, and sufficient watering can promote the combination of the pepper root system and the soil.

Another important watering period for peppers is the fruit setting period, which should be properly watered according to the external environment. Generally, it is watered every 5-7 days, and the watering time is controlled in the morning or evening. At this time, you can water more often to avoid increasing soil moisture and affecting root growth.

The demand for fertilizer for pepper is relatively high, and it is necessary to apply a balanced water-soluble fertilizer to pepper seedlings. During this period, nitrogen, phosphorus, and potassium should be supplemented in a balanced manner, and nitrogen fertilizer should not be used alone. This may lead to vigorous growth of pepper seedlings, affecting flower bud differentiation, resulting in less flowering and low fruit set.

The application rate of phosphorus should be increased during the flowering stage of pepper, because phosphorus can promote nutrient transport like flowers, promote flower and fruit preservation, and help to increase yield in the later stage. <>

From planting to flowering, the main purpose of fertilization is to facilitate the plant from planting to flowering. The main purpose of fertilization is to promote healthy plant growth and lay a solid foundation for later flowering and fruiting. 7 10 days after planting, about 8 kg of high-nitrogen liquid fertilizer should be applied per mu, but the liquid fertilizer concentration must be low.

In the budding stage, there is a lot of demand for nutrients, not only to meet the nutrient needs of plant germination, branching, and germination, but also to prevent overgrowth of plants. Therefore, at this stage, nitrogen and phosphorus fertilizers should be applied together. Generally, 5 kg of urea and 7 kg of superphosphate are applied per mu.

It can be seen that the demand for phosphate fertilizer is not very large during the whole growth and development period of peppers. As we said in the Fertilizer Characteristics of Peppers, although the demand is small, it is very important for the growth and development of peppers. Therefore, it is necessary to pay attention to the application of phosphate fertilizer when fertilizing.
