Can potassium fertilizer be applied during the fruiting period of peppers, and what fertilizer is go

Pepper growth requires sufficient nitrogen, phosphorus and potassium, but nitrogen and potassium should not be too much at the seedling stage, so as not to grow too vigorously and delay flower bud differentiation and fruiting. Phosphorus plays an important role in the formation and development of flowers, potassium is an essential element for fruit expansion, nitrogen, phosphorus and potassium must be coordinated with each other in production, and on the basis of applying foot fertilizer, do a good job of topdressing to improve yield and quality.

Top dressing and watering: After transplanting, until before flowering, light animal manure should be applied lightly and diligently to maintain the green leaves of the seedlings and promote the differentiation of flower buds. From the opening of the first flower to the fruit setting of the first branch, it is generally necessary to control the top dressing, otherwise it will cause a large number of flowers and fruits to fall due to too much nitrogen fertilizer.

When the first layer of green and mature fruits is close to harvesting, and the fruits of the second to third layers are gradually growing, in order to make the fruits and plants continue to grow and expand rapidly, fast-acting fertilizer should be applied 1-2 times in time, generally 667 square meters of urea kilograms each time, and 4000-4500 kg of human and animal manure water to ensure that the plants are not defertilized. In the stage of large-scale harvesting, the consumption of nutrients is large, and the method of diligent pursuit must be adopted, which can be applied every 4-5 days to rot acquaintances and animal manure (500-750 kg each time for 667 square meters, add 3-4 times of water), and pour it in the early morning or evening. Therefore, in the middle of summer, the temperature is high and the water evaporates quickly, so it is necessary to be wet when pouring to ensure that the plants pass the summer smoothly.

After turning into the autumn cool, it is the period of a large number of autumn pepper fruit set, every 667 square meters should be applied with 3000-4000 kg of urea and manure water, and then applied once every 5-7 days, so that the top fruit can still grow normally and ensure high yield in the later stage.

Yes, potassium fertilizer can be used during the fruiting period of peppers, which can help the fruit to expand, increase the weight of a single fruit, and increase the yield. It also enhances the taste of chili peppers. It is recommended to apply potassium nitrate in a rush of less than 10 kg per mu each time.

When the pepper has expanded its fruit, it has changed from vegetative growth to reproductive growth at this time, and we need to use some high-potassium fertilizers, such as potassium sulfate.

Potassium nitrate or potassium monobasic phosphate.

These three are more, potassium sulfate its potassium content is the highest, its potassium content pure potassium sulfate can reach 52 potassium, if we use nitrogen fertilizer in the early stage, then we can use potassium sulfate in the fruit expansion period, we suggest that when the pepper is in the fruit expansion stage, it is best to use potassium nitrate, because potassium nitrate not only contains high potassium, but also contains nitrate nitrogen, so it is said that pepper has absolute benefits in the fruit expansion period, that is, in addition to nitrogen ions and high potassium ions.

Another type of potassium is potassium dihydrogen phosphate, which contains both phosphorus.

There is also potassium.

Potassium dihydrogen phosphate is mainly in the fruit expansion period, in addition to using potassium nitrate, we can also cooperate with foliar spraying potassium dihydrogen phosphate (multi-fruit plus high phosphorus and high potassium), which can ensure that the pepper does not defertilize during the fruit expansion period, and at the same time can achieve the purpose of high yield or increased yield.

From the first harvest to the beginning of autumn, the pepper fruit period is generally 15 20 kg of compound fertilizer per mu each time, and 10 kg of urea can be added if necessary.

Usually take one chase once, a total of 3 5 times. It can be divided into pepper growth and fruiting amount, after the beginning of autumn before the summer, in order to end the rest as soon as possible, you can apply an appropriate amount of manure, plus about 15 20 kg of compound fertilizer, can promote the increase of pepper production.

Peppers have the greatest absorption of potassium during their lifetime, followed by the least amount of nitrogen followed by phosphorus. The amount of nitrogen fertilizer is too large, the nutrition of pepper plants is too vigorous, the fruit is deficient in calcium, and it is easy to develop umbilical rot, therefore, special attention should be paid to adjusting nitrogen fertilizer in the grass flowering period to prevent the length of pepper plants from causing slow reproductive growth. As the pepper plant grows, the uptake of phosphorus increases, but during that growing period, the total uptake of phosphorus is only one-third of that of nitrogen.

Potassium application helps the synthesis and transport of photopolymers in caps, improves the stress resistance of plants, and improves vitamin C in fruits

content, effectively reduce the nitrate nitrogen content of peppers, promote fruit coloring, and improve commerciality. Pepper needs a lot of nitrogen fertilizer in the growth period, so nitrogen fertilizer needs to be applied in the reproductive growth period, phosphorus and potassium fertilizers are deployed, and the fertilizer demand is increased from the flowering and fruiting stage to the stage topdressing.

Chili fertilizer should adhere to the combination of organic fertilizer and inorganic fertilizer, foot fertilizer, appropriate top dressing, potassium flavor, myopia.

Pepper topdressing should be carried out during high temperature periods, especially top dressing with ammonium carbonate.

When using nitrogen fertilizers such as urea, it should be done in the morning and evening when the weather is cool. The amount of nitrogen fertilizer used is too much, the nutrition is too vigorous, and the fruit can not get calcium in time**, resulting in navel rot, and pepper plants are not resistant to high temperature due to calcium deficiency, and are easy to be swept away. Super firearms should be especially restrained in nitrogen fertilizers.

Otherwise the plant will grow, and the reproductive growth will be greatly delayed. Pepper has a long growth period, likes temperature and light, but the roots are not developed, the number of roots is small, the soil is shallow, drought tolerant, waterlogging tolerant, fertilizer is more, and fertilizer tolerance is strong.

Chili peppers belong to the infinite growing type. In other words, Bian Xianlei blossoms and bears fruit. We can perform a variety of harvests based on this growth characteristic of peppers.

Pepper has a long growth period, likes temperature and light, but the roots are not developed, the number of roots is small, the soil is shallow, drought tolerant, waterlogging tolerant, fertilizer is more, and fertilizer tolerance is strong. Chili peppers are eggplants and crops that are sensitive to goats, avoid goat crops. Therefore, only potassium sulfate compound fertilizer can be used for compound fertilizer.

If farmhouse fertilizer is not available, a balanced compound fertilizer is applied.

It is best to add an appropriate amount of biofertilizer. Chili peppers are eaten with fresh chili peppers, and some are made into dried chili peppers. Autumn rain to make fresh peppers is nitrogen fertilizer, but not in excess.

Otherwise, the fruit rate of the king is low. The focus of making dried chili peppers is on the basis of the red nitrogen fertilizer on the fruit, which is a partial potassium fertilizer. Potassium is the element that determines the color and quality of dried chili peppers.

Yes, peppers absorb the most potassium in their lifetime, and nitrogen followed by phosphorus is the least, because peppers belong to the infinite growth type, that is, Bian Xianlei, flowering, and fruiting, so potassium fertilizer is needed no matter what period.

Peppers absorb the most potassium in their lifetime, followed by nitrogen and phosphorus. If the amount of nitrogen fertilizer is too large, it will promote the vegetative growth of pepper plants, which will easily lead to the lack of calcium in the fruit and produce umbilical rot. With the growth of pepper plants, the uptake of phosphorus increased, but the total uptake of phosphorus during the growth period was only 1 3 of nitrogen.

Potassium application is beneficial to the synthesis and transport of photosynthetic products in pepper, which can enhance plant stress resistance, increase vitamin C content and effectively reduce nitrate nitrogen content in pepper, promote fruit coloring, and improve commerciality.

Potassium application is beneficial to the synthesis and transportation of photosynthetic products of pepper, which can enhance plant stress resistance, increase the vitamin C content of fruits, effectively reduce the nitrate nitrogen content of pepper, promote fruit coloring, and improve the character.

Need. <>

First, the demand for nitrogen, phosphorus, and potassium in peppers:

1. Sufficient nitrogen, phosphorus and potassium are required during the growth period of pepper, but too much nitrogen and potassium should not be too much at the seedling stage, so as not to grow too vigorously and delay the differentiation and fruiting of flower buds.

Phosphorus plays an important role in the formation and development of flowers, potassium is an essential element for fruit expansion, nitrogen, phosphorus, potassium must be coordinated with each other in production, and top dressing should be done on the basis of applying foot fertilizer. Top dressing can be used as soil chef effect fertilizer, which has a good effect on improving the yield and quality of peppers.

2. Pepper is sensitive to potassium fertilizer, and the soil is deficient in potassium.

Pepper plants are short and weak, easy to lodging, the leaves are curled, the old leaves gradually turn yellow, there is a phenomenon of "leaf burning", and potassium fertilizer can enhance the metabolism of pepper.

Beneficial for the formation of starch and sugar.

The application of potassium fertilizer can increase the absorption of nitrogen and phosphorus, which is conducive to the formation of protein, and can improve the cold tolerance, drought resistance, disease resistance and lodging resistance of plants.

3. Nitrogen and potassium fertilizers should be heavy in pepper fertilization, and the demand for phosphate fertilizers is not large, but for calcium, magnesium and boron and other medium and trace elements.

High demand. Second, the law of fertilizer needs during the growth period of peppers:

1. From the emergence of seedlings to the emergence of buds, the plant has fewer roots, small leaves, and less nutrients.

2. From budding to early flowering, the growth of plants is accelerated, the plants expand rapidly, and the absorption of nutrients increases.

3. From the first flowering to the full flowering and fruiting, it is a period of vigorous vegetative growth and reproductive growth, and it is the period when nitrogen is absorbed the most.

4. From full flowering to maturity, the vegetative growth of the plant is weak, and the demand for phosphorus and potassium is large.

Third, the effect of potassium deficiency on chili peppers:

Potassium-deficient cytoplasm of young leaves of pepper seedlings.

The water potential is low, the cell elongation is hindered, the growth of leaves, stems and roots is affected, the expansion of leaf area is hindered, the number of stomata per unit leaf area is reduced, the stomatal opening is reduced, the final photosynthetic products are reduced, and the yield is reduced.

Need. Potassium fertilizer is a large number of elemental fertilizers that are indispensable for plant growth, and the effect on plant growth is very large, and the lack of potassium fertilizer usually causes crop growth disorders, resulting in reduced disease resistance, reduced quality and reduced yield.

Fertilizer use during the seedling stage of peppers. Vegetable farmers attach great importance to pepper seedlings, and "pepper seedlings are half as good as peppers", which is indeed the case. Therefore, the poor growth of pepper seedlings will affect the development of the later stage, and there will be late flowering and late fruiting, and the yield will be low.

Vegetable farmers on pepper seedlings, usually use the furrow seedling method, before sowing every 10 square meters of furrow ground with fully fermented rotten and ripe fine mixed organic manure 150 200 kg, and add 1 3 kg of superphosphate, potassium sulfate kg, and the soil is fully mixed evenly, can also use ordinary ternary compound fertilizer 1 kg and seedbed soil mixed evenly. In this way, the seedlings are raised and the fertilizer is used reasonably, and the pepper seedlings grow vigorously and robustly, which lays a solid foundation for the formation of healthy strong seedlings, improving the fruit setting rate and increasing the yield in the later stage, and has a good effect.

After transplanting and planting pepper seedlings, cultivation is the key. If the cultivation is good, the pepper seedlings grow fast, the flowering is early, the fruit is set early, the market is in the morning, and the market is occupied early, and the economic benefits will be higher. After the pepper seedlings are planted, seize the time, combined with watering, cultivating and loosening the soil, weeding and insect control.

First cultivate and weed, and then water the slow seedling water combined with the application of thin human manure and urine, but also per mu with the water to apply a kilogram of urea, but also the use of trichlorfon poisonous soil to control underground pests, and then squat seedlings. After squatting seedlings, apply flower and fruit fertilizer, use 2000 2500 kg of fully fermented and rotted human feces per mu, and 8 12 kg of urea can also be used, and water after application. Every 10 15 days, after watering once, fertilize again according to the amount of fertilizer applied last time.

The first fertilization in the pepper seedlings planted to survive, with 1% ammonium sulfate aqueous solution 500 kg per mu of root watering, after an interval of 10 days and then with water per mu of urea can be, and then apply human urine and phosphate fertilizer, potassium fertilizer and other fertilizers when flowering and fruit set, which is conducive to fruit setting and high yield.

Fertilizer is also thrown in and irrigated with water, and that's it. Seedlings absorb to. Moisture and fertilizer, growing strong men. Very good.

The pepper topdressing method.

Type of fertilizer. The pepper has a large demand for fertilizer, from the emergence to the bud, the nutrients needed are less, the growth of the plant from the bud to the first flowering plant is accelerated, the demand for nutrients increases, from the first flower to the full flowering fruiting is the vigorous period, at this time it is necessary to apply nitrogen fertilizer, full flowering to the mature period, to increase phosphorus, potassium fertilizer, after the harvest of mature fruits, nitrogen fertilizer needs to be applied.

When the pepper is topdressed, urea and compound fertilizer can be used, urea is a very basic fertilizer, which can supplement the nitrogen fertilizer required by the pepper, the pepper is a crop with high nitrogen and high potassium phosphorus, in order to be able to have sufficient nutrients, compound fertilizer must be used, the pepper can be picked many times after maturity, and a large number of top dressing is required in the middle and late stages.

Top dressing time. 1. The pepper in different growth stages, the amount of nitrogen, phosphorus, potassium and other nutrients absorbed is different, from the emergence to the bud, the number of leaves is small, the dry matter accumulation is slow, so the need for nutrients is less.

2. After transplanting, the pepper can be topdressed once when watering the planting water, and a small amount of water-soluble phosphorus can be applied, which is beneficial to the growth of new roots and can improve the survival rate.

Top dressing specific links.

The first fertilization: After the pepper survives, the first top dressing can be carried out, ammonium sulfate aqueous solution can be applied, and the roots can be watered.

Second fertilization: When the pepper buds, use the diluted fertilizer or calcium sulfate mixed with water to make an aqueous solution and water to water the roots.

The third fertilization: in May, the first cluster of fruits began to grow, at this time more nutrients are needed, it is advisable to use fast-acting fertilizer, with stool fertilizer point root burning or ammonium sulfate, superphosphate, the above fertilizer is mixed evenly and then applied in the strip or hole, and then watered once.

The fourth fertilization: in June, the temperature is high, this is the vigorous growth period, combined with water delivery, fertilizer amount and fertilization method can be followed by the third top dressing.

The fifth time to do cautious fertilization: in August, the weather is hot, the pepper grows slowly, the leaf color is light green, the fruit is small and the fruit is small, you can apply fertilizer or ammonium sulfate aqueous solution.

The sixth fertilization: in September, a top dressing can be carried out, and the application rate and fertilization method can be followed by the fifth time, which can increase the yield.

Precautions. The pepper can reduce the number of fertilization before flowering, otherwise it will cause growth, resulting in falling flowers and fruits, it is a potassium-loving crop, at the end of flowering, fruiting period, maturity period to apply sufficient potassium fertilizer, it is best to use fast-acting instant, stool bureau full environmental protection chelated high potassium water-soluble fertilizer pure coarse, before the flowering period and fruiting period to supplement calcium fertilizer, depending on the soil conditions of the planting site.
