High-yield Cultivation Techniques of Small Pepper

1. Variety selection. Small wheat stubble should be selected for dry products with compact plant shape, good early maturity, standard pepper shape and high spiciness. Such as: Sanying Pepper, Nanyang Red, etc.

2. Raise seedlings in time. The seedling raising time is about 20 days later than the spring pepper. Generally in early April, after the seedbed is built, water first. After the water seeps down, the dry seeds are evenly sown in the seedbed, with about 300 grams per mu. The sowing amount per unit area is not easy to be too large, otherwise the seedlings are too thin and too weak, which is not conducive to returning to seedlings after planting. Then cover about 1 cm with fine sand, set up the bow frame, and cover with a film. Water and pull the weeds at the right time during the seedling stage, pay attention to letting out the wind later, and gradually expose the film as the temperature increases.

Three, fixed value

1. Soil selection. Hot peppers* avoid repeated cropping, and plant them on sandy soil plots that have not been planted in the past 3 years with high dryness and convenient drainage and irrigation.

2. Plant early when grabbing. In order to ensure that the pepper has enough nutrient area, it is necessary to harvest wheat as early as possible and pay close attention to stubble and soil preparation. Combined with land preparation, 50 kg of superphosphate and 50 kg of carbon ammonia can be applied per mu, rotary tillage 2-3 times, and border planting. The growing period of the wheat stubble pepper is short and the nutrient area per plant is relatively small, so it should be planted appropriately. When planting, make shallow furrows at 33-40 cm, keep the hole spacing about 15 cm, and 2-3 plants per hole. Since the temperature is higher when planting, it is necessary to water the plant along with it to ensure survival.

4. Field governance

1. Cultivation and soil cultivation, and timely cultivation and weeding after slow seedling. In the heyday of branching, it is necessary to cultivate the soil twice to promote the occurrence of lateral roots and prevent waterlogging.

2. Fertilizer and water management, the amount of topdressing for small peppers in wheat stubble should not be too large, especially N fertilizer, otherwise the peppers will not turn red in time in the later period, and the quality of goods will decline. *Apply 30 kg of three-element compound fertilizer per mu during the branching period, and spray foliar fertilizers in combination with pest control in the later period. Small peppers are afraid of both drought and waterlogging. Water should be watered in time in dry weather, and waterlogged should be drained in time in case of heavy rain to prevent accumulation of water in the field.

3. Pest control. The main diseases of small peppers are: leaf fall disease, leaf spot disease and virus disease. The occurrence of leaf fall disease and leaf spot disease is related to the weather. Low-lying plots are more prone to disease at high temperature and humidity. Mancozeb or thiophanate-methyl WP can be used to prevent and control the disease in the early stage. Viral diseases are weak and weak. Early aphids damage the plots are prone to occur, so enhancing plant growth and controlling aphids is the key to preventing and controlling the disease. Insect pests mainly include aphids, cotton bollworm and corn borer. Aphids mainly occur in the branching stage and should be controlled with imidacloprid as early as possible. Helicoverpa armigera and corn borer mainly occur in the fruiting stage, and they must be sprayed with enemy killer, deltamethrin and other high-efficiency low-poison insecticides during the juvenile period, or use poison bait to trap adults.

Five, harvest. The wheat stubble peppers are harvested relatively late, usually before and after frost. Before harvest, spray with 40% ethephon 300-400 times to accelerate ripening, which will promote some green peppers to turn red after harvest and improve product quality and economic income.
