Embodiment 1

[0022] Example 1 Contrast experiment of planting corn multiplication ladybug and controlling peach aphid in round eggplant and sweet pepper greenhouse

[0023] Experiments were carried out in the eggplant and sweet pepper greenhouses of Beijing Noah Organic Agriculture Company in Pinggu District, Beijing. Set up eggplant control greenhouses and eggplant corn belt treatment greenhouses, sweet pepper control greenhouses and sweet pepper corn belt treatment greenhouses, each with a size of 500m 2 The planting spacing, row spacing and density of round eggplant and sweet pepper are the same as conventional cultivation methods, the planting spacing of round eggplant is 60cm, the planting spacing of sweet pepper is 40cm, and the planting density of round eggplant and sweet pepper is 2 rows per border. The border width of round eggplants and sweet peppers in the greenhouse is not less than 60 cm, and the organic vegetable management standards are used for daily farming operations, and...

Abstract

The invention relates to a method for propagating and protecting natural enemy insects by planting corns between vegetables in a greenhouse. According the method, a present method for planting vegetables in greenhouse is kept, the row spacing of vegetables, line spacing of the vegetables and the density of the vegetables are the same as those of a present planting method. The method comprises planting two rows of corns at an inlet of a 500 m2 greenhouse, inoculating 50 Rhopalosiphum padi or Rhopalosiphum maidis on each corn when the corns are as high as 30 cm, and inoculating 10 3rd-instar ladybird larvae on each corn after 5 days. The method provides food for natural enemies in the earlier stage and later stage of production of vegetables in the greenhouse, so the natural enemies can be propagated in position in the greenhouse in advance or collected in the later, the rate and the utilization rate of colonization of the natural enemies can be raised. The natural enemies can be continuously propagated and protected by adopting the invention, and operation is simple and the cost is low.

Description

technical field [0001] The invention relates to a method for planting corn in greenhouse vegetables to proliferate and protect natural enemy insects, belonging to the field of agricultural technology protection. Background technique [0002] Greenhouse vegetables are one of the core production modes in the modern agricultural production system. The production environment of greenhouse vegetables is relatively closed, and herbivorous pests are easy to breed and break out, seriously affecting the quality and safety of vegetables. In recent years, the comprehensive ecological function system of biological control with natural enemy insects as the core has increasingly become the only way to realize pollution-free and green organic greenhouse fruit and vegetable production. Whether natural enemies can colonize in the greenhouse is an important factor affecting the ability of natural enemies to control insects, especially the effect of continuous control. [0003] Aphids are on...
