Abstract

The invention provides a pollution-free insect prevention method for a vegetable greenhouse. The method comprises the following steps of 1, performing planting pretreatment A and setting an insect prevention net, wherein two insect prevention curtains are arranged at a greenhouse inlet; performing soil preparation and building a closed plastic shed, wherein weeding is performed, during deep ploughing, attapulgite, quick lime and organic fertilizer are spread into soil, exposure is performed for 4-5 d, a greenhouse membrane is uncovered, after 1-2 days, water is sprayed, a hymexazol aqueous solution with the concentration of 30% added with water is sprayed to soil, 0.15-0.25 kg of the hymexazol aqueous solution with the concentration of 30% is applied to each mu of soil, the greenhouse is covered with a film again, dry lantana, dry rosemary and dry Dalmatian chrysanthemum are burnt inside the greenhouse, the closed plastic shed is built, ploughing and airing are performed, and biological bacterial fertilizer is applied; 2, performing planting post-treatment, wherein an insecticidal lamp is arranged, insect prevention treatment is performed, and natural plant insecticide is sprayed into the greenhouse every 20-30 d. On the condition that a small amount of low-toxicity and pollution-free chemical pesticide is adopted, the good insect prevention effect is achieved, the vegetable growth soil environment can be improved, and environment-friendly organic vegetables can be obtained.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a pollution-free and insect-proof method for vegetable greenhouses. Background technique [0002] Greenhouse vegetable planting technology is a relatively common technology, it has good heat preservation performance, it is very popular, because you can eat off-season vegetables at any time. Under normal circumstances, greenhouse vegetables use bamboo and steel-based structural framework, and then cover one or more layers of thermal insulation plastic film on it, such a simple structure can create a complete greenhouse space. The plastic film can effectively prevent the loss of carbon dioxide produced during the growth of vegetables, so as to achieve the insulation effect required in the greenhouse. [0003] Because the temperature and humidity in the vegetable greenhouse are more suitable for the growth of various vegetable pests, the existing vegetable greenhouse ...
