How to increase vegetable production in greenhouses to increase economic benefits? This is a problem that growers are very concerned about. Here, we suggest that you can increase production through the following aspects of management: First, thoroughly clean the vegetable garden and do a good job in the disinfection of garden soil The number of continuous cropping vegetables in the greenhouse is relatively high, and the disease is generally serious. Therefore, before the cultivation, the leaves of the leaves of the former tendon must be thoroughly cleaned out of the shed, and then the carbendazim powder or the chemical reagents such as methanol etc. must be used for the garden soil. Thoroughly sterilize it so that it can kill pathogens that spread disease by soil and reduce the incidence. Second, improve the greenhouse structure and improve the greenhouse temperature control capabilities The back wall of the greenhouse is thickened to 1.2 meters. On the outside of the back wall in winter, the layer of corn straw is 30-40 centimeters thick; the drip-free membrane is covered, the quantity of water droplets in the greenhouse is reduced, and the light transmission capacity is enhanced to facilitate the improvement. Room temperature. Double-layer insulation measures are adopted to add a layer of plastic film or a small arch shed in the shed to increase the ground temperature by 2°C. Set reflective film, set a reflective film in the low light area on the north side of the booth, which can significantly enhance the illumination on the north side of the booth and increase the ground temperature by 1.5°C-3°C. Third, fine soil preparation, application of base fertilizer Before the site preparation, 5-6 cubic meters of cooked organic fertilizer, 40 kg of diammonium, and 20 kg of potassium sulfate were applied per acre greenhouse vegetable plots. Then, the soil was deep-turned 25 centimeters, and the fertilizer was turned into the soil and the soil was well-grounded. Reach deep, flat and fine standards. Fourth, reasonable arrangements for gargle, increase the multiple cropping index According to the different fertility characteristics of different vegetables, appropriate varieties were selected, and gingiva were rationally arranged. Multi-cultivation, intercropping, and three-dimensional cultivation were used to increase the multiple crop index. Fully increase the land utilization rate and output 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, so that the economic benefits can be maximized. Fifth, choose suitable for greenhouse cultivation The use of plastic greenhouses to grow vegetables requires stricter varieties. In greenhouses grown in winter-warm greenhouses, varieties resistant to low temperature and low light should be selected; in spring-type plastic greenhouses, winter and spring vegetables should be cultivated, and the early energy-tolerance, low-light, early-maturing and early-maturing conditions should be selected. Variety; greenhouse delayed cultivation in the fall, to use early heat resistance, and the results of more concentrated vegetable varieties. Six, application of plant growth regulators, and 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 eggplant and melon vegetables. Flowers and pods can increase fruit setting rate, prevent flower drop, promote fruit enlargement, and accelerate fruit formation Earloop Kn95 Face Mask,Kn95 Fold Flat Face Mask,Kn95 Filters Respirator,Kn95 Protective Face Mask Jiangmen anjian biotechnology co.
