How to select chili peppers grown on wheat stubble

①Seed selection: For wheat stubble chili pepper seeds, it is suitable to use early-maturing varieties with strong heat and moisture resistance.

② Seed treatment: Turn the seeds over and dry them for 2-3 days before seedling raising to activate seed vitality and ensure germination rate. Soak them in warm water at about 55℃ after drying, stirring them while soaking until the water temperature drops to 30℃, then stop stirring, let them stand for 7-10 hours, wash and drain.

③ Seeding and seedling raising: The general seedling raising time for chili pepper is from February to March in early spring. The seedling raising time for chili pepper grown on wheat stubble should be appropriately delayed to ensure that the strong seedlings can be planted immediately after wheat harvest, usually around early April. Strengthen management during the seedling stage to cultivate strong seedlings.

How to apply fertilizer to pepper on wheat stubble

After the peppers set, pay attention to the drought in the pepper field and water it in time. If it rains heavily, drain the water in time.

At the same time, pay attention to the prevention and control of pepper virus diseases. During the fruit setting period, spray acetamiprid + chlorothalonil + plant disease killer + foliar fertilizer every 7-10 days. You can also choose other pesticides to prevent white leafhoppers and aphids.

What soil is suitable for pepper growing on wheat stubble?

The seedling bed should be selected from a plot of land that has not been planted with peppers or Solanaceae crops before. One acre of wheat stubble chili seedlings requires a 10-square-meter seedling bed. It is best to choose 20 kilograms of organic fertilizer and about 3 pounds of potassium sulfate compound fertilizer as the base fertilizer for the seedling bed. Use a shovel to dig the ground and then use an iron rake to level it. The seedling bed is 1.2 meters wide. Water it thoroughly once. When watering, you can sprinkle some fungicides and pesticides to prevent and control underground pests. When there is no stagnant water, you can spread the pepper seeds, and then cover it with a layer of soil and cover it with mulch. Build a small arch shed on it, and remove the mulch after 3-5 days of emergence. Pay attention to ventilation as the temperature rises, and you can remove the arch shed in mid-April.

① Selection of wheat fields: Peppers should not be planted in the same crop, and the same is true for chili peppers. Therefore, chili peppers grown on wheat stubble are suitable for planting in wheat fields that have not been planted with peppers for three consecutive years, preferably sandy loam wheat fields with higher terrain and convenient drainage and irrigation.

② Reasonable planting. In order to ensure that the chili peppers can obtain sufficient nutrition, the wheat is harvested in advance, and then the land is prepared and base fertilizer is applied immediately. 40 to 50 kg of superphosphate and 40 to 50 kg of ammonium carbon are applied per mu, and then the peppers are planted along the banks with a reasonable density.
