How to grow pepper in early spring

Immediately after the beginning of spring, and to the early spring pepper breeding season, Fujian Shanghang generally in the middle and late February, farmers and friends are using plastic film covering seedlings, can be planted early season, mentioning the city to increase vegetable benefits.

1. Variety selection: The cultivation should adopt varieties such as strong growth potential, disease resistance, and high heat-resistant varieties such as Taijiao No. 5, Medium No., and Yuanshuai Sweet Pepper 218.

2, choose to do 畦, should choose fertile land, sunny leeward, the former 茬 did not plant pepper, eggplant, tomato plots do 畦. According to an acre seed amount of 150 grams for nursery.

3, scientific fertilization, Shizujifei: According to the demand in time to deepen the sun, soil disinfection, the commonly used disinfectants are Green Heng No. 1, No. 2, seedbed disinfection to prevent seedling disease. To raise the seedlings in the leeches, sifting 100-150 kg of rotten organic fertilizer and 1-1.5 kg of ternary compound fertilizer per 15 m2 of nursery bed, doubly mixing with the soil. Do not apply ammonium bicarbonate, sulfuric acid because the surface is sealed. Ammonium is used as a basal fertilizer to prevent ammonia from injuring the seedlings.

4, sowing, nursery: Shanghang general in February such as the use of greenhouses, plastic film covering seedlings can be sown. In order to raise the seedlings in the field, after the completion of the earthworms, fill the bottom water, fertilize and flatten the land, spread the seeds of sweet pepper evenly, cover 0.5 - 0.8 cm of fine soil, do not exceed 1 cm, increase the seedling emergence rate, and then cover the mulching film. Sealed with plastic film, control the temperature during the day about 25 °C, night 18 °C -20 °C. After 60% emergence, remove the plastic film, pay attention to moisturizing, and use a fine watering can to spray water evenly to increase the humidity, increase the intensity of photosynthesis, and protect the growth of seedlings.

Plastic seedlings are used. Preparation of nutritious soil: 50% of the fertile surface sandy loam soil not grown with eggplant vegetables, 50% of manure with decomposed sifting, 0.5-1 kg of NPK fertilizer per cubic meter, 50% carbendazim 80- 100 grams or green hen No. 5 grams. After mixing with good materials, the soil and fertilizer are fully mixed and then filled with nutrients, soaked in bottom water before sowing, and seeds that have been rushed through the seed are broadcast live.

5, seedling management: to avoid overcrowding seedlings, starting from the heart of 1 leaf, seedlings should be divided in time, between the seedlings, 3 leaves 1 heart Dingmiao, 5 cm from the hole to ensure that there is sufficient nutritional area. In 2-3 true leaves, 3-4 true leaves and 7-10 days before colonization, spray 0.2% potassium dihydrogen phosphate + 0.1% urea + 0.2% zinc sulfate mixed fertilizer solution to promote flower bud differentiation and Improve plant disease resistance.

Temperature control, soil temperature after sowing can maintain 28 °C -30 °C. When the seedlings plow soil to about 25 °C, the minimum soil temperature maintained at night 18 °C -20 °C can promote seedlings. The daytime maximum temperature of the seedlings should be maintained at 23°C-25°C and gradually decreased from 20°C to 15°C-17°C at night. Gradually reduce the temperature 7-10 days before planting, seedlings for low-temperature exercise, the daytime temperature can be reduced to 18 °C -20 °C, night 10 °C -12 °C.

When the pepper seedlings grow up to 18-25 cm, the stalks are thick, the internodes are short, the stems are 0.3-0.5 cm thick, there are 8-14 true leaves, the cotyledons are intact, the true leaf color is dark green, and the leaves are large and thick, with 70 %-80% of plants have big buds, no pests and diseases, transplanting can be carried out when the root system is developed.

Greenhouse Wet Pad For Cooling System

"Wet curtain - fan" of the vertical ventilation cooling combination is the most economical and effective measures to cool the greenhouse in summer.
Years from the application of a real show, even in the heat of the day reported, the rational design and installation of a fan of wet curtain cooling system can still control the greenhouse temperature at 30 °C, in order to heat the greenhouse to reduce the adverse effects minimum. In the summer, your production needs Jienuo wet curtain to help.
