I. Variety selection
The wheat cultivars and peppers should be cultivated with heat-resistant and moisture-resistant varieties. In the northern regions, there are mainly early-maturing pepper hybrids such as No.10 and No.11 of Baojiao pepper.
Second, nursery
1, sowing time
According to the wheat harvest, pepper planting period is pushed forward for 60 days to calculate the seedling raising period. Generally, the seedlings are sowed from the end of March to the beginning of April, and the seedling age is 55-60 days. Before and after June 10, they are planted in wheat stubble.
2, floating seedlings
Build nursery plastic greenhouses, then lay nursery ponds according to pepper planting area, generally according to the nursery of 67,500-75 thousand plants per acre. After the nursery pool is built, prevent the floating seedling tray and floating special nursery fertilizer before the seedling tray is filled with water. Kg configuration nutrient solution. Each seedling hole was sown with 1-2 seed coats and seeded at a depth of 5-10 mm. Using the method of sowing the back cover substrate first, a layer of 1-2 mm thick substrate is sprinkled on the seed surface after sowing.
3, seedling management
The principle of water management for floating seedlings is "first less and more." From sowing to the Grand Cross period, the water depth is generally controlled at 5-6 cm. The temperature of the pepper seedlings gradually rises after the true leaves of the pepper seedlings are started. The water depth in the nutrition pool can be added to 8-10 cm. In principle, the seedlings are kept flat. The depth of water in the pond is just right; in the case of 4-5 true leaves, 20 g of special fertilizer for floating seedlings is used for each fertility disc for the second fertilization, and the seedlings are sprayed with potassium dihydrogen phosphate and urea mixture according to the growing conditions of the seedlings. Supplementary nutrition promotes the healthy growth of pepper seedlings, and fertilizer spraying intervals are 7-10 days. In order to prevent the production of green algae by adding 1 gram of copper sulphate to each seedling pan, dilute evenly into the nursery pond at 5 points and mix well; -25°C.
Third, do the earthwork
The cultivation of wheat aphid and pepper should be emphasized. To achieve strong early mechanical harvesting, early fertilization, mulching and filming, and early four-zone planting. Can be applied to ternary compound fertilizer 750 kilograms per acre plus urea 300 kilograms per acre, 1.2 meters with ridge type mulching.
Fourth, colonization
Each ridge was planted with 2 rows of narrow rows and colonies. The width of the row was 70 cm and the length of 50 cm was 33 cm. The triangles were staggered and colonized. After planting, the water was planted in a timely manner.
V. Field Management
The temperature during the colonization of wheat pods and peppers is relatively high, and the seedlings are not slowed down and grow fast. Therefore, it is necessary to promote cultivation of the plants before the hot weather comes in July. Therefore, the water should be poured in a timely manner. During the fruiting period, the amount of water should be increased. Chili peppers should be drained in time after flooding. The principle of fertilization is to apply 1 seedling fertilizer after easing the seedlings, apply 150 kg of urea per mu; after fruiting, the fruit should be followed by Pengguo fertilizer once and apply 225-300 kg of fertilizer per acre. Before and after the beginning of the fall, the flowering result is in full bloom, and 300 kg of compound fertilizer is applied per mu to prevent premature aging and increase production. Each fertilization should be done in conjunction with watering. In the initial stage of colonization, the cultivator promoted the hair roots, and the peppers sat on the first soil after sitting on the soil. In the middle and early July, the pillar ridges were used for the second soil cultivation.
6. Harvesting
According to market conditions and fruit size harvest. Timely harvesting will affect the fruit growth in the later period. The late autumn season, after suitable late harvesting or harvesting, the silage preservation will not only increase the sale price, but also increase the economic benefits.
