Problems solved by technology

[0002] At present, the prevention and control of pests in agriculture still relies on chemical control to a large extent, and the large-scale use of chemical pesticides in chemical control has caused three major problems: the increase of pest resistance, the rampant pests, the pesticide residues in food exceeding the standard, and the damage of farmland itself. Severely reduced natural regulation
Wheat-corn rotation is the crop planting mode with the largest planting area in North China. However, under the background of agricultural intensification in

Embodiment 1

[0022] A method for helping to move predatory natural enemies from the wheat field to the corn field, the number of rows of wheat is 40, the number of rows of Fructus Cnidii is 1, the number of rows of corn is 16 rows, and the equal row spacing of the wheat belt is planted, and the row spacing is 20cm. The above-mentioned corn belts are planted with equal row spacing, and the row spacing is 50cm. The wheat is winter wheat, and the corn is summer corn

Embodiment 2

[0024] A method for helping to move predatory natural enemies from a wheat field to a corn field, the number of rows of wheat is 160, the number of rows of Fructus Cnidii is 2, the number of rows of corn is 80 rows, the row spacing of said Cnidium is 40cm, and the number of rows of Cnidium is 40cm. The equidistant planting, the row spacing is 25cm, and the equidistant planting of the corn belts, the row spacing is 50cm. The wheat is winter wheat, and the corn is summer corn

Embodiment 3

[0026] A method for helping to move predatory natural enemies from a wheat field to a corn field, the number of rows of wheat is 180, the number of rows of Fructus Cnidii is 3, the number of rows of corn is 54 rows, the row spacing of said Cnidium is 33cm, and the number of rows of Cnidium is 33cm. The equidistant planting, the row spacing is 21cm, and the equidistant planting of the corn belts, the row spacing is 70cm. The wheat is winter wheat, and the corn is summer corn

Abstract

The invention belongs to the technical field of biological control of agricultural pests, and particularly relates to a method for assisting the migration of predatory natural enemies from wheat fields to maize fields. The method of assisting the migration of predatory natural enemies from wheat fields to maize fields is implemented by planting cnidium monnieri zones beside wheat-maize rotation fields, wherein the ratio of the number of rows of wheat zones to the number of rows of cnidium monnieri zones is 40-80:1 or the ratio of the number of rows of maize zones to the number of rows of cnidium monnieri zones is 15-45:1, the wheat zones, the maize zones and the cnidium monnieri zones are uniform, the row spacing of the wheat zones is 18-25cm, the row spacing of the maize zones is 50-70cm,and the row spacing of the cnidium monnieri zones is 33-40cm. The method for assisting the migration of predatory natural enemies from wheat fields to maize fields provided by the invention is efficient and simple, and can increase the income of farmers. Moreover, the seeds of cnidium monnieri will not diffuse into the farmland to interfere with the growth of crops in the farmland, and thus, themethod is of high safety.

Description

technical field [0001] The invention belongs to the technical field of biological control of agricultural pests, and in particular relates to a method for assisting the migration of predatory natural enemies from wheat fields to corn fields. Background technique [0002] At present, the prevention and control of pests in agriculture still relies on chemical control to a large extent, and the large-scale use of chemical pesticides in chemical control has caused three major problems: the increase of pest resistance, the rampant pests, the pesticide residues in food exceeding the standard, and the farmland itself. Natural regulation is severely reduced. Biological control reduces the use of chemical pesticides by using biocontrol microorganisms and natural enemy insects to control pests. However, in the past, biological control mainly focused on crop habitats, and used physical, chemical and biological methods to control pests, which were rarely used. The method of planting fu...
