Apple pest control method through attraction and breeding of natural enemies by using mixed grown grass in apple garden

Abstract

The invention discloses an apple pest control method through attraction and breeding of natural enemies by using mixed grown grass in an apple orchard. According to the occurrence rule and characteristics of apple pests, a mixed grass growing pattern combining artificial grass planting and natural grass growing can be formed in the apple orchard through artificial planting of grass species, and specifically in the apple growing season, the mixed grass growing pattern of natural weeds, Medicago sativa, Vicia villosa Roth, Tagetes patula and Tagetes erecta can be formed in the apple orchard; attraction and breeding of the natural enemies can be achieved through different flowering periods of the grass species, and food and habitats are provided for the natural enemies, so that the species and quantity of the natural enemies in the apple orchard can be maintained at a high level for a long period of time, and the goal of continuous control of apple pest harm can be achieved.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for attracting and breeding natural enemies with mixed grass in an apple orchard to prevent and control apple pests. Background technique [0002] Apple is the largest fruit variety in China. In my country, the cultivated area and output of apples account for about 20% and 30% of the total fruit. Since 2005, my country has become the world's largest apple production and consumption country. At present, serious pest damage is still an important factor restricting the high-quality production of apples in my country. The basic research work on apple pests in my country is relatively weak, and the work on integrated pest control is also relatively backward. In recent years, with the change of orchard cultivation techniques, the types and numbers of pests in the orchard have changed, mainly manifested in the rotation of primary and secondary pests. Aphids and spider mi...

AI Technical Summary

Problems solved by technology

At present, the flowering period of grass species in orchards is relatively short, and most of them are concentrated in May-June, but the peak occurrence of apple pests and natural enemies is mostly concentrated in July-October. The current common grass species and grass-growing methods in orchards are difficult to meet the peak occurrence of natural enemies The demand for nectar sources during the period
