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

Embodiment 1

[0062] The experiment of the mixed grass pattern of natural weeds + alfalfa + vetch on the number of pests and natural enemies in apple orchard was carried out in the apple orchard of Henghe Family Farm Co., Ltd., Yishui County, Shandong Province. Set up two treatments of mixed grass area and natural grass area, each treatment has 3 repeated areas, each test area has 15 rows of fruit trees, and each row of fruit trees is 80m. In October 2016 in the mixed grass area, alfalfa was planted by machine between rows of fruit trees, every 667m 2 Sow 0.5-1.0kg of alfalfa seeds in the apple orchard, and sow a small amount of vetch in the open space between the fruit trees and on the edge of the apple orchard, every 667m 2 Apple orchards are sown with 0.5-1.0 kg of vetch seeds, and the weeds in the garden are artificially removed in the early stage, and the natural weeds in the garden that consume less water and fertilizer are retained after July. In the natural grass-growing area, the ...

Embodiment 2

[0069] The experiment on the effect of the mixed grass pattern of alfalfa + vetch + peacock grass + marigold + natural grass species on the occurrence of apple pests and natural enemies was carried out in the apple orchard of Chouguoguo Agricultural Development Co., Ltd., Qufu City, Shandong Province. In October 2016, 2 rows of alfalfa were artificially planted between the rows of fruit trees, each 667m 2 Sow 0.5-1.0kg of alfalfa seeds in the apple orchard, and spread a small amount of vetch seeds between the fruit trees, every 667m 2 Sow 0.5-1.0kg of alfalfa seeds in the apple orchard, and artificially sow peacock grass and marigold in the open places between apple rows in May 2017, every 667m 2 Sow 100-200g of peacock grass and marigold seeds each in the apple orchard, and at the same time retain the natural grass species in the garden that consume less water and fertilizer, foxtail, crabgrass, chickweed, and quinoa, and form natural weeds in the apple growing season+ In th...

Abstract

The invention discloses a method for attracting and breeding natural enemies to prevent and control apple pests by mixing grass in apple orchards. According to the occurrence rules and characteristics of apple pests, the invention forms artificial grass and natural grass in the apple orchard by artificially planting some grass species Combined mixed grass pattern, that is, to form a mixed grass pattern in apple orchards in the apple growing season of natural weeds + alfalfa + succulents + peacock grass + marigold, and use these grass species in different flowering periods to attract and breed natural natural enemies, Provide food and habitat for natural enemies, so that the types and quantities of natural enemies in the apple orchard can be kept at a high level for a long time, so as to achieve the purpose of continuously controlling the damage of apple pests.

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...
