Green comprehensive prevention and control method for thrips on southern melon type vegetables

Abstract

The invention discloses a green comprehensive prevention and control method for thrips on southern melon type vegetables, and relates to the technical field of agricultural planting. According to themethod, sufficient photo-thermal conditions in southern China are utilized for soil disinfection to kill thrip adults, nymphs and pupae, and traditional Chinese medicine type active defense is performed on diseases and pests by cultivating strong seedlings, additionally applying organic fertilizer and Chinese herbal medicine extraction nutrient solutions, reducing application of chemical fertilizers and the like to improve plant immunity. The number of thrips is controlled by releasing natural enemies such as predatory mites and predatory stinkbugs and the like in the field, tight bagging is performed by using insect-proof mesh bags after fruit setting to prevent the thrips from damaging melons and fruits; agricultural prevention and control, physical prevention and control and biologicalprevention and control measures are taken as main measures, chemical prevention and control measures are taken as auxiliary measures in the field management process, so that damage of thrips to melonvegetables is reduced; after the method is comprehensively implemented, thrips are prevented and controlled from multiple angles and multiple time periods, a good thrip prevention and control effect can be achieved, the yield and quality of melon vegetables can be improved, the quality safety of vegetable products can be guaranteed; and meanwhile, environmental pollution caused by excessive use ofchemical pesticides can be avoided, and therefore better economic benefits, social benefits and ecological benefits are brought.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a comprehensive method for green prevention and control of thrips in the production of melon vegetables in southern regions.
