What are the planting techniques for planting peppers on a large area to enhance drought resistance?

Improve the water-holding capacity of the soil. The water and fertilizer retention capacity of some soils is particularly poor, which is largely due to the long-term use of chemical fertilizers. Therefore, in order to improve the water and fertilizer retention capacity of the soil, it is necessary to improve the soil quality.

For the north, drought management is a more important point. Generally speaking, in order to preserve soil moisture, we often use plastic film mulching technology. Pepper cultivation is also covered with mulch.

Especially in early spring, because of the early transplanting, the temperature is low and the sand and gravel are laid, and the ground is covered with small stones with a thickness of more than 20 cm, and then the pepper seedlings are planted. The advantage of laying stones is that grass does not grow, because the stones are thick, which keeps the evaporation of water very well, and can collect rainwater well when it rains.

Pepper topdressing and flower and fruit preservation: 5-10 kg of urea per mu is applied after live seedlings, which can be topdressed with water. After flowering, apply 25 kg of compound fertilizer per mu, and use potassium dihydrogen carbonate plus borax root topdressing, once every 7 days, three times.

During the period when peppers bloom in a large area, watering should be properly controlled to avoid pepper flowering. When the pepper turns red, it is necessary to water less, at any time, the soil is in distress, and not watered in the case of drought.

Before harvesting, it is necessary to water a little water, early top dressing, combined with tillage, top dressing phosphorus and potassium fertilizer to promote the healthy growth of seedlings, prevent flower dropping, and remove the side branches on the main stem below the first flower. During the harvest period, the pepper should be harvested in advance, watered and cultivated in time, and fertilizer should be applied. Chaotian pepper is not too harsh on the general requirements of geology, first of all, the choice of planting terrain should pay attention to the drought can be watered, waterlogged can be drained, because Chaotian pepper is afraid of flooding, if the rainy season is too rainy, the pepper field can not be drained, there will be a danger of extinction.

<> combined with land preparation and ploughing before planting, 4000 6000 kg of decomposed organic fertilizer, 75 kg of superphosphate and 30 kg of ammonia bicarbonate were applied per mu of land as base fertilizer. In the period before the flowering of peppers, 3000 kg of rotten and fermented farm fertilizer is applied per mu, and 50 kg of compound fertilizer is applied per mu during the fruiting period of peppers.

1. Choose drought-tolerant varieties for planting peppers, especially vegetable farmers in the Yangtze River Basin, because the temperature in this area is high within three dog days, and there are autumn tigers after the beginning of autumn, and it is high temperature, and the probability of drought is higher.

2. It is best to buy pepper seedlings directly for transplanting, in this way, as long as the watering is timely and the management is appropriate, the survival rate of pepper is relatively high, and the drought resistance is good for management in the later stage.

3. In the hot and dry weather, you should water frequently in the morning and evening, if possible, a small amount and many times, water every day, not too wet, the pepper will die if it is wet.

4. You can make a simple shade net on the top of the pepper, and use a black shade net, which has a good effect.

To improve the drought resistance of chili peppers, we can first choose chili varieties that are drought resistant. Secondly, re-applying organic fertilizer in pepper-growing areas can also greatly improve the drought resistance of peppers.

When the weather and temperature are very low, water once a week, and you can wash it with a small amount of thin manure water. Note that when rinsing dilute fertilizer water, do not use it with plant ash to avoid reducing fertilizer utilization. When the weather gets hot, you don't need to water the fertilizer again so as not to "burn" the plant.

Fertilizers should be used for top dressing.

As one of the vegetables that many people can't live without, chili peppers are widely cultivated throughout the country. With the exception of some greenhouse-grown peppers, open-air cultivation accounts for a very large proportion. In rural areas, almost all the chili peppers grown by villagers are grown in the open air.

Peppers grown in the open air, in order to obtain a better yield, will be affected by the external environment. Among them, long-term high temperature and rainless weather will affect the yield of peppers. The specific reasons are as follows:

1. The impact of drought caused by high temperature and no rain.

The growth period of pepper plants is relatively long, and the fruiting ability is also very strong, especially when it comes to the peak of pepper fruiting, the demand for water of pepper plants is also very large. In such a critical period, there is a long period of high temperature and no rain, which will naturally affect the flowering, pollination, fruit set, and expansion of peppers. The impact of each of these stages will affect the final yield of the pepper.

Countermeasures: When the weather is hot, there may be no rain for half a month or even more than a month. In such weather, you must not hope that it will rain all day, but prepare yourself for drought in advance.

For us rural people, we don't grow many peppers, and drought resistance is also a relatively simple thing. Directly find a long plastic hose and connect it to the faucet at home, and you can fight drought. When we water peppers to fight drought, we should avoid the high temperature of noon, and choose after 5-6 p.m., at least when the temperature of the soil is cooler.

2. Premature aging of pepper seedlings caused by high temperature environment.

After the pepper plant enters the hot weather, the pepper is like a disease. The plants grow slower, fewer flowers bloom, and fewer peppers are produced. In fact, at this time, it is because the temperature is too high, which causes the pepper seedlings to lie dormant.

In addition to the pepper seedlings will be dormant, and the pepper seedlings will also appear premature aging. If the pepper seness early, the fruiting ability of the pepper seedlings in the later stage will be greatly reduced.

Countermeasures: After the hot weather comes, we should not only pay attention to drought management, but also pay attention to avoid early aging of peppers. Therefore, generally before entering the hot weather, we should carry out a top dressing, which is mainly nitrogen fertilizer, mainly to avoid premature aging of peppers.

In addition, the temperature in the small environment where the pepper field is located is not too high can be managed through the necessary shading. It would be even better if the temperature could be controlled.

In this case, the yield of peppers will be greatly reduced, because the temperature is relatively high for a long time, and then the land will dry up if it does not rain, and then there may be cracks in the surface, and then there may be cracks in the plants.

It will affect the growth rate of peppers, and it will also affect the yield of peppers, and peppers may also have damaged roots, wilted roots and fallen peppers.

It will affect the growth of peppers, root rot, and the color of peppers, shrinkage, and dead trees, which will cause serious flower and fruit drops.

Pepper is not a drought-tolerant and waterlogg-tolerant plant, so improving the drought resistance of pepper is one of the key factors to improve the yield of pepper planting. When planting peppers in a large area to enhance drought resistance, you need to pay attention to the following six tips: <>

1. Choose drought-tolerant varieties.

To plant peppers, you should choose drought-tolerant varieties, such as Qianla No. 3, Luoyan No. 5, Zhitian pepper, Zhente red pepper and so on. <>

2. Cover the straw.

Buy pepper seedlings directly for planting, and after watering the rooting water, cover the ground with a layer of straw, wheat and other straws. It can not only keep heat, moisturize, and retain soil, but also prevent weeds, which can ensure that water is not disturbed and lost, and can enhance the drought resistance of peppers. <>

3. Reasonable dense planting.

Reasonable dense planting can avoid the competition for water and nutrients between seedlings, and the field leaf area tends to be reasonable, which can effectively reduce the transpiration of field leaves and reduce water evaporation. Generally, the planting distance is 30-35 cm from the sharp pepper, and the green pepper is 40-45 cm. 4. Watering in time.

When there is a drought, it is necessary to water it in time. When watering, you need to choose the right time, the best time to water is in the evening, so that after a night of pepper slow stove can absorb enough water. If possible, hang a shade net to avoid direct sunlight.

5. Remove the side branches.

Remove the excess side branches in time to keep the pepper field ventilated and light. Because the root system of pepper is not developed, in order to make its root system developed, so that it can resist both drought and waterlogging. 6. Improve soil quality Some soils have a particularly poor ability to retain water and fertilizer, so it is very important to improve soil quality, and the method can be used to increase the use of organic fertilizer in farmers.

The soil has strong water retention capacity and slow water evaporation, which is very helpful for the improvement of drought resistance of pepper.

Speaking of the cultivation of chili peppers, the family just transplanted chili peppers into the ground a few days ago. I remember that there used to be a saying "peppers grow flowers, eggplant grows pods", and the pepper seedlings that I didn't want to buy this time really had a small bud. However, after transplanting into the field, those small flower buds have not yet bloomed.

However, it doesn't look like it falling, and as soon as the flowers bloom, I feel that the fresh peppers are not far away. Peppers have a lot to do with the management of fruit preservation. Fertilization, watering, pruning, top dressing, disease prevention, etc.

These links all have the effect of preserving fruits. Generally speaking, as long as the pepper seedlings are not thriving and the peppers are not prosperous, the peppers will generally tie the knot. It should be noted that the water and fertilizer of chili pepper should be properly managed to avoid water shortage.

When we transplant pepper seedlings, we need to increase the soles of peppers. Peppers can be planted in the ridges of the manure ditch, which is more effective and direct. For the north, drought management is a more important point.

Generally speaking, we often use plastic film mulching technology for soil and water conservation. Xiangqiao.

The cultivation of chili peppers is the same, it must be covered with mulch. Especially for early spring peppers, due to the fast transplanting, it is necessary to first pad low-temperature sand and stones, and then spread small stones more than 20 cm thick in the field to plant pepper seedlings. The advantage of laying gravel is that grass does not grow.

By laying gravel, the evaporation of water is well maintained, and rainwater can be collected well even when it rains. I grow chili peppers in the countryside. The technique is simple and crude, but there are several entrances inside.

In order to ensure that the chili peppers are drought resistant, the villagers have their own methods of growing the chili peppers when planting.

Here, according to the habit of cultivating chili peppers here, I will explain how chili peppers keep the soil rich. Chili peppers are very common in our lives, and there are some places where we have to eat chili peppers three times a day. This shows the ubiquity and popularity of chili peppers.

The regeneration ability of pepper root is weak, and the oxygen content in the soil is high. When the oxygen content in the soil exceeds 20%, peppers absorb nutrients and grow faster.

First of all, to ensure the air permeability of the soil, it is necessary to water regularly to avoid the soil being too dry, to ensure the indoor temperature, and to fertilize regularly to improve the yield.

To dismantle the technology of mulching film, so that the temperature of the soil can be increased, and then watering, transplanting, timely cleaning of stagnant water, a trillion envy must pay attention to ventilation, improve the quality of the soil royal soil.

First of all, we must vigorously improve the ability of the soil to retain water and fertilizer, improve the soil quality, cover with film, and properly control the loss of watering during the large-scale flowering period, and must timely top dressing the bridge.

Peppers need sufficient nitrogen, phosphorus, and potassium nutrients throughout the growth period. There are certain differences in the types and quantities of fertilizers required for different growth and development periods. Nitrogen fertilizer is the most, which should not only meet the growth of stems and leaves, but also meet the expansion of fruits.

Phosphorus and potassium fertilizer can promote root growth, fruit expansion, and increase fruit color. The period from the germination of pepper seeds to the appearance of the first true leaves. During the whole germination stage, nutrients are mainly supplied by the seeds themselves, and the absorption capacity of young roots is weak.

This stage promotes seed germination and rapid emergence after sowing, preventing excessive consumption of nutrients by seeds, which can lead to seedling weakness. Timely topdressing is beneficial to increase the number of flowering and fruiting. Management measures such as fertilization and water can regulate the balance of vegetative and reproductive growth, as well as the growth of above-ground stems and leaves and underground roots.

The temperature is required to be 25 degrees to 28 degrees during the day and 15 degrees to 20 degrees at night. Above 35 degrees Celsius will not bear fruit, and below 10 degrees Celsius will not flower. Phosphorus and potassium fertilizers are very important for flower bud formation and seedling development.

Insufficient phosphorus fertilizer will dwarf pepper seedlings, reduce the number of flower buds, and form short flowers that cannot bear fruit. Therefore, if the base fertilizer is not applied with phosphorus and potassium fertilizer, it must be applied during this period. The best stubble for pepper stubble is onion and garlic stubble.

Root exudates from onions and garlic vegetables kill the earth-borne pathogens of chili peppers. Onion and garlic vegetables also differ from peppers in terms of nutritional properties and fertilizer absorption, and the nutrients can complement each other, especially trace elements.

The planting of pepper is too thin, so that the pepper plant can not seal the ridge in the high temperature season, which is easy to cause the occurrence of pepper virus disease and pepper sunburn, which directly leads to low total yield and low efficiency of pepper. Pepper planting is too dense, especially in protected areas, which can easily lead to poor ventilation and light transmission conditions in pepper fields, resulting in excessive humidity in the field and various diseases of peppers. Reasonable dense planting of pepper is an important measure to achieve high yield of pepper. Proper dense planting depends on the specific characteristics of the cultivated pepper variety.

For example, the pepper planted is large and has a large degree of development, so it needs to be planted sparsely. Pepper plants are short and compact and can be densely planted. In pepper cultivation, improper watering and drainage can lead to a decrease in yield and efficiency.

Especially when watering pepper plots with large slopes, low-lying pepper plots are prone to hemp wetting or dying of disease.

Growing peppers in greenhouses mainly manages fertilizer and water diseases to achieve high yields!

Ensure sufficient sunlight, water and fertilizer are reasonable.

Ensure suitable humidity, temperature, weeding, cultivating, and soil accompaniment. Control pests and diseases.

Ensure sufficient sunlight, water and fertilizer are applied reasonably.

If you maintain the right humidity and temperature, you can achieve high yields if you manage water and fertilizer well.

Greenhouse is mainly temperature, humidity, water and fertilizer and pest control.

Ensure the temperature and humidity in the shed, water, fertilizer and nutrition management, and pest control.

Strengthen the control of water, fertilizer, gas and heat, pests and diseases, and reasonable dense planting.

Water and fertilizer management, temperature control, and early prevention of pests and diseases.

Strengthen the coordination of water, fertilizer, gas and heat, and strengthen the prevention of diseases and pests.

1.Variety selection: Greenhouse early pepper should choose extremely early maturing varieties that are resistant to low temperature, high humidity, weak light, strong disease resistance, easy fruit setting and fruit hanging. 2.

The best time to plant pepper seedlings is around October 20 last year, and the sowing in this period is 7 days earlier than that in early November. 3.Sowing amaranth at the appropriate time, planting peppers in early January in plastic greenhouses to sow amaranth, per 667 square meters of seed amount of kilograms.

4.Field management: After the amaranth emerges, the mulch film is replaced with a small arch shed, which is mainly heated and insulated in the early stage, and covered on the small arch shed when the temperature is low and there is frost. 4.

Timely harvesting of cabbage about 50 days after sowing seedlings can be marketed, positioning peppers, pepper rhizosphere 5-8 cm range amaranth root whole harvest.
