Regeneration cultivation technology of pepper in autumn and winter in solar greenhouse

During the autumn and winter stubble production in the solar greenhouse, the results are susceptible to long-term low-temperature, low-light, and humid weather in the later stage, which often causes small plant growth, cluster flowers formation, ineffective flowering, and seedless fruit formation, which causes great losses to vegetable farmers. In recent years, we have adopted the regenerative cultivation technology of pepper in autumn and winter in sunlight greenhouses, and have achieved good results. The specific measures and cultivation techniques are as follows:

1 Production advantages

1.1 Fast-growing, early fruiting. Since the pepper does not go through the seedling stage after regeneration, the side branches that are sent out bear flower buds, which directly flower and bear fruit, which is earlier than the big pepper seedling.

1.2 The amount of early results is large, and the benefits are high. Spring production must have large amounts of early results, and high yields can be highly effective. The regeneration cultivation of peppers in the greenhouse in autumn and winter is fully in line with the requirements of spring production.

1.3 The plant is not oversized, and it is easy to manage. The side branches of regenerated pepper are large, and there are many results.

2 regeneration time

Usually in mid-February to late March, which is the normal planting time of peppers in the solar greenhouse in spring. If the weather turns fast and the ground temperature is high, pepper regeneration will be carried out in the middle and late February. When the temperature is lower than 20 ° C, chili regeneration takes place in early March.

3 Regeneration technology

3.1 Suitable varieties The varieties used for the regeneration of peppers in autumn and winter in sunlight greenhouses should have the characteristics of low temperature resistance and strong growth potential. Such as Luojiao No.4, Luojiao No.8, Nongyan No.13, Yanyan No.1, Xiaojiao No.7 and so on.

3.2 Regeneration site The regeneration site is that all the branches above the "four female buckets" of the pepper are cut with pruning shears.

3.3 Fertilize the land immediately after trimming. Ridge-cultivated peppers are applied with 2 cubic meters of high-quality organic fertilizer per acre in the ditch, and mixed with 50 kg of superphosphate, 15 kg of urea, and 10 kg of potassium sulfate. Spread the ground to a depth of 15-20 cm. There are too many injuries. After fertilizing and preparing the land, re-cover the mulch to ensure the use of organic fertilizer and increase the ground temperature. If the soil is too dry, you can irrigate a small amount of water under the mulch.

3.4 Field management After pruning, the temperature during the day shall be controlled above 28 ° C and at night above 12 ° C. Before the new branch appeared, cover the grasshopper late at night to maintain a high temperature. After the new branch is 2 to 3 cm, more light should be seen within a suitable range to ensure the temperature. Forty minutes after the grass was lifted on a clear day, the ventilation hole was ventilated for about an hour after being opened, and it was re-vented once at 2 noon for 1 hour. After opening the grasshopper on cloudy and rainy days, open the ventilation hole 1 hour, the ventilation time is 40 ~ 50 minutes, and the ventilation time is 40 minutes at noon temperature *. When the temperature is sunny, the ventilation should be increased to facilitate flowering and pollination. After the side branches appear, it is easy to have multiple buds or too many dense branches. At this time, leave enough side branches according to the growth of the pepper plant and weather conditions. Generally, leave 7 to 10 side branches and wipe the excess branches. Off. Nitrogen, phosphorus, and potassium compound quick-acting fertilizer was applied with water when the pepper and fruit were half-fruited, 5 kg per acre. As the number of harvests increased, the frequency of watering and fertilizing was increased, and the fertilizer was flushed once every 1 to 2 times.

Through the cultivation in recent years, we have obtained a comparison result. The regenerated pepper has a 67% increase in the initial yield of pepper seedlings with large flower buds planted at the same time. The total yield is basically the same, and the continuous yield is 32% lower at the market price. It is calculated that the total output value can be increased by 1,000 to 1,500 yuan per mu.
