As the weather turns cold, vegetable production is transferred to greenhouses and greenhouses. How can we increase the output of greenhouse vegetables and increase economic benefits? The vegetable farmers can manage it carefully in the following ways: First, thoroughly clean the vegetable garden Because of the number of consecutive crops in greenhouses, the diseases are generally serious. Therefore, the stubble leaves of the former tendon must be thoroughly cleaned out of the shed before farming, and the garden soil must be completely sterilized with chemical agents. Soil-borne disease pathogens reduce the incidence. Disinfection method is: 3-5 grams of carbendazim powder is sterilized per square meter of garden soil. Second, improve the greenhouse structure The back wall of the greenhouse is thickened to 1.2 meters. In the winter, on the outside of the back wall, it is surrounded by a layer of 30-40 centimeters thick corn stalks; it covers the blue non-drop film, reduces the formation of water droplets in the greenhouse, and enhances the light transmission capacity. Raise the room temperature; adopt multi-layer covering and heat preservation measures, add a layer of plastic film or set a small shed in the greenhouse; setting a reflective film in the low light area on the north side of the shed can significantly enhance the light on the north side of the shed. Increase the ground temperature 1.5°C-3°C. Third, fine soil preparation, application of base fertilizer Before the site preparation, apply 5-6 cubic meters of decomposed high-quality organic fertilizer per acre, and then apply 40 kg of diammonium and 20 kg of potassium sulfate. Then deep-dip 25 cm deep with a shovel and turn the fertilizer into the soil. It is well-grounded to allow the soil to reach deep, flat and fine standards. 4. Arranging mouth rinsing rationally and increasing the multiple cropping index According to the different fertility characteristics of different vegetables, selecting appropriate varieties, rationally arranging estuaries, using intercropping, three-dimensional cultivation and other forms to increase the multiple cropping index and fully increase the land utilization rate. In addition, the vegetable varieties planted in the shed must be determined according to the market conditions, aiming at the market is empty, supplement the shortages, and develop more fine vegetables and high-grade vegetables. V. Selecting good varieties suitable for cultivation The cultivation of vegetables in greenhouses requires stricter varieties. In the greenhouse cultivation of cucumbers, varieties that are resistant to low temperature and low light, such as Changchun Mimi, Xintai Michong, and 87-2, etc., should be selected; in the spring-use plastic greenhouses, winter and spring vegetables can be cultivated, and the early energy-tolerance, low light, and early maturing must be selected. , late to adapt to high temperature environment, disease resistance, high yield varieties. In late autumn cultivation of greenhouses, it is necessary to select vegetable varieties with early high temperature resistance and relatively concentrated results. Six, application of plant growth regulators, while artificial pollination Solanaceous vegetables can't be pollinated under conditions of low temperature and no insect pollination. Therefore, plant hormones, such as 2,4-D butyl ester and anti-dropping agents, are applied in time after the flowering of solanaceous fruits and legume vegetables. Flowers and pods can increase fruit setting rate, prevent flowering and fruit drop, promote fruit enlargement, accelerate fruit ripening, and effectively increase yield.
