The management of greenhouse pepper after colonization

First, soil preparation Fertilizer greenhouse pepper generally nursery in early August, three leaf stage seedlings, planting in late September to early October. Before the planting, per acre Shi Man farmyard fertilizer 6000 ~ 8000 kg, 10 kg of DAP, cooked cake fat 50 ~ 100 kg, deep plowing, picking fine, leveling, do saddle-shaped stilts, the width of 1.2 meters. Planting large row spacing 70 cm, small row spacing 50 cm, plant spacing 25 to 28 cm, planting water after planting.
Second, strong seedlings The standard seedling age is about 30 days. The stems are short and thick, the internodes are short, the seedling height is not more than 25 centimeters, and there are 8 to 12 true leaves. The buds of the first inflorescence can be seen; the leaves are thick and stretched. Dark green and shiny; roots developed, many lateral roots, white. Balanced development of the whole plant, no pests and diseases.
Third, after the planting, the peppers were controlled and then poured into a slow water, shallow loose soil and bacon. In mid-to-late October, the shed was tarred. After the shed is properly watered, soil loosened, ridges raised, and then covered with plastic film. The daytime temperature is maintained at 25°C to 30°C and nighttime at 13°C to 18°C. After the fruit is set, the temperature begins to drop and attention should be paid to keeping warm. When the temperature is low and it is not easy to set fruit, 2,4-D or anti-dropping agents can be used. When the bell pepper begins to expand, it will combine irrigated water to recover 8 to 10 kg of urea per mu. After that, every 2 to 3 weeks will be followed by a thin fertilizer. Before and after the New Year's Day, depending on the market conditions, it is appropriate to market the peppers. Each young plant has about 10 young fruits and it is topped with water to promote growth. All markets are harvested before and after the Spring Festival market.
Fourth, chemical regulation When the early flowering pepper grows too prosperous long time, you can use paclobutrazol, chlormequat or shrinkage and other plant growth regulators for chemical control, in order to increase the fruit set rate of autumn greenhouse post greenhouse, can also be used auxin (2 , 4-D or anti-dropping) treatment, the effect of flower protection and fruit preservation is good, 2,4-D concentration is 15 ~ 20ppm, the effect of flowering before 10 o'clock in the morning is better.
5. The peppers growing in the pruning-proof greenhouses have strong growth, large plant shape, and easy branching of branches. They are convenient for operation and convenient for ventilation. They can be suspended on plastic ropes or fixed on the outside of ridges with bamboo rafts to prevent plant lodging. . The branches that are too thin and the old leaves and fruitless branches on the lower part of the plant can be sparsely cut to save nutrients and are conducive to air and light transmission.
VI. Insulation In the cold winter season, the outside temperature drops sharply, and the growth of peppers is relatively slow. Therefore, it is important to prevent freezing injury in temperature management. However, when the weather is good at midday, the air should be released for a short time to reduce the temperature, humidity and ventilation. After mid-January, in order to prolong the harvesting and supply period of peppers, a small shed can be taken in the greenhouse and covered at the same time for insulation.
Seven, disease prevention and pest control using greenhouse isolation cultivation, the surrounding mesh and sunroof net yarn should be intact, can be repelled insects and other insect transmission routes, therefore, few pests, virus disease can also be effectively controlled. When the virus disease is slightly harmful, use virus A to spray 2 or 3 times continuously to control the hazard.
VIII. When the timely harvested peppers are ripe, if the price is reasonable at the time, the peppers and peppers can be removed from the sale to reduce the burden on the plants, which is beneficial to the growth and expansion of the fruits above the peppers. The price is also low.
