Improve the efficiency of greenhouse vegetable
In recent years, due to many years of heavy-grained planting and production management, the greenhouse vegetable producing areas have caused soil compaction, salinization, and accumulation of pathogenic bacteria in the soil, resulting in severe plant diseases and insect pests, reduced yield, and poor quality. Therefore, it is necessary to change the traditional cultivation management model to improve the planting efficiency of vegetables. Below, introduce six measures for efficient cultivation of vegetables. First, choose the best Excellent varieties are the basis for high yield and high efficiency in the production of vegetables. In particular, greenhouse vegetable production is different from ordinary open field vegetable production. Shelf room vegetable varieties need to be resistant to low temperatures, weak light, strong disease resistance, and high yield. Traits. Second, laying a plastic film The environment inside the shelters is a relatively closed and humid environment, which is conducive to the growth and development of various germs. Vegetables can easily cause various diseases. The mulch film is laid in the cultivation pot to reduce the evaporation of water, reduce the humidity in the shed, and reduce the formation of water droplets, which can effectively reduce the occurrence of vegetable diseases. In production, especially the production of fruit and vegetable vegetables, it can be covered with a 0.014 mm thick polyethylene film. Third, stamping insect nets In recent years, pests that injure vegetables have been intensifying. In particular, pests such as whitefly, aphids, cabbage caterpillars, diamondback moth, and beet armyworm often pose serious threats to the yield and quality of vegetables. Placing pest control nets in protective vegetable production in greenhouses is a kind of measures for controlling pests with low input, high yield, labor saving, and high safety. During the active period of pests, 30 mesh white insect nets were used to cover or cover the air outlets to cut off the entrance of external insects, which can effectively reduce the number of insect populations in the shed. Fourth, the yellow trap Hanging the yellow boards in the sheds must be closely integrated with the stamped insect nets, and the two-pronged approach can effectively curb the occurrence of pests. Generally occupying an acre of sheds can hang about 20 boards, about 60 centimeters from the ground, smear oil on them and evenly hang the yellow boards in the shed. The yellow plate can trap and kill pests such as whitefly, locust, and sucking mouthparts. V. Using drip irrigation The greenhouse vegetable production requires higher investment in fertilizer and water. According to investigations, according to the traditional irrigation method, a vegetable shed occupying an area of ​​one acre has 700 cubic meters of irrigation water per year. In fact, 50% of the moisture penetrates underground and evaporates, causing Serious waste of water resources. The drip-irrigation irrigation method not only can greatly increase the utilization rate of water resources, but also can improve the environment in the shed and reduce the occurrence of diseases. The drip irrigation should be closely integrated with the mulching film in the shed cultivation bed. Six, high ridge cultivation Using high-ridge cultivation is a good measure to increase ground temperature, increase fertilizer utilization, save water, and reduce the occurrence of diseases. Especially fruits and vegetables such as cucumber, eggplant, tomato, sweet pepper, summer squash, etc. have obvious production increase effect by adopting this measure. High ridge cultivation is closely combined with related technical measures such as laying mulch, submerged furrow irrigation or laying drip irrigation pipes, and the effect will be better.
