Cultivation and Management techniques of Pepper in Autumn extension (part I)

Pepper autumn extension cultivation is an important form of pepper cultivation, especially in many main producing areas of muskmelon, planting pepper after harvest can effectively control soil-borne diseases, pepper and the next crop of muskmelon grow well and the yield is higher. In addition, because Qiuyan chili mainly supplies the market from November to February, the price is high, so the benefit of autumn chili is good in most years, so the enthusiasm of growers is very high. However, the planting of Qiuyan pepper is generally in the middle and late July, when the average temperature is the highest, Rain Water is the most, and the light is the strongest in a year, which is very disadvantageous to the growth of chili. If there is a slight carelessness in management, it will cause the occurrence of quenching disease, blight, root rot and virus disease. In order to help growers manage autumn chili peppers well and avoid economic losses, the management techniques of Weili Company after years of exploration and summary are introduced as follows:

I. Variety selection

After the postponement of autumn, the hot pepper in the greenhouse had high temperature and strong light in the early stage, rainy and rainy in the early stage, and low temperature and low light in the later stage, which required strict varieties. You can choose the excellent yellow pepper variety launched by Weili Company. The fruit of this variety is 28cm long and 35cm long, the weight of single fruit can reach 120g, and the fruit is straight and smooth. Fast fruit expansion, strong continuous fruit setting ability, high yield, up to 5000 kg per mu. Strong disease resistance and stress resistance, easy to manage.

2. Seed and seedling selection

Hot pepper in autumn has high temperature, strong light and heavy rain, which requires high seedling facilities and techniques. One is easy to fail and the other is poor quality, especially the poor flower bud differentiation, which seriously affects the yield and quality of pepper. Therefore, we recommend the use of Weili company standardized production of high-quality pepper seedlings.

III. Land preparation and planting

1. In the soil treatment, Dijujing, carbendazim, methyl thiophanate, dimethazone, oxamyl, etc. were used to treat the soil, which were mixed into poisonous soil and scattered evenly into the soil. Avermectin is used to kill insects, and 7 grams per mu is applied with water. Or use thiazolyl phosphine (Fu Qi duo) 2 kg / mu.

two。 Land preparation and fertilization per mu using fully mature high-quality organic fertilizer 8 square, humic acid fertilizer 20 kg, biological bacteria (to be used in low light) 1.5 kg (for high yield ditch, concentrated application of organic fertilizer). Use 50 kilograms of high-quality high-potassium compound fertilizer and 20 kilograms of silicon-calcium-potassium fertilizer. Then turn deeply or plough deeply (not less than 25cm). After raking flat, a small high ridge of 15cm and 20cm (must be ridged).

3. Greenhouse disinfection high temperature stuffy shed, and disinfect with insecticidal and germicidal aerosol (airtight shed when in use).

4. Greenhouse cooling (1) sprinkle mud to cool, start to use before transplanting, need to lower the temperature to less than 33 ℃.

(2) the vent should be at the bottom and shoulder (or top) of the shed to form convection in order to achieve the cooling effect.

(3) Silver gray film is recommended for mulching, with the black side facing down and covered after planting.

5. When the seedlings are 15 to 20cm high, 0.5cm in stem diameter, with 8 to 10 true leaves, the calendar seedling age is about 30 days, and 80% of the seedlings are close to budding, 3000,500 seedlings per mu; before planting, use Ruisheng 20g + Amicida 10ml in water 30kg, dipped in 2000 seedlings Before planting, the seedling bed should be sprayed with Ami colorful plus aminooligosaccharides to prevent the disease at seedling stage. Planting should be carried out in cloudy or sunny afternoon while pouring through the planting water.
