Method for preventing Athetis lepigone by mechanically removing straw on corn seeding lines

Abstract

The invention relates to a method for preventing Athetis lepigone by mechanically removing straw on corn seeding lines. The method is characterized in that due to the fact that the distance between a furrow opener of a seeder and a fertilizer applying device of the seeder is increased to be 10 cm, the straw scattered on the seeding lines can be separated to the two sides of seeding furrows, straw accumulation does not exist on the seeding lines after corn seedlings emerge, the environment suitable for the Athetis lepigone to inhabit to do harm is not formed, and the prevention effect can be higher than 90%; in addition, the later-period prevention and control labor intensity and the later-period prevention and control economic input are greatly reduced, meanwhile, mechanical operation is achieved, and the method is suitable for large area use; the efficient and nuisanceless prevention aim is achieved; under the condition that at present, the field wheat straw is not advocated to be removed, or turnover plowing after wheat harvesting is not advocated, the method is worthy of popularization and application.

Description

technical field [0001] The invention relates to a method for preventing and controlling agricultural pests, in particular to a method for using mechanized large-area clean sowing rows of wheat straw to prevent and control the spodoptera moth. Background technique [0002] Two o'clock moth[ Athetis lepigone (M?schler, 1860)] is a new agricultural pest in my country's summer corn production areas. In July 2005, it was first discovered in Shijiazhuang, Hebei Province that the two-spot moth harms summer corn seedlings, bores the base of the stem, causes the seedlings to wilt and die, or bites off the corn roots, leading to lodging and severe seedling shortage. Ridge, in 2010, the insect generally occurred in the summer corn area in the central and southern part of Hebei Province. In 2011, it broke out in Hebei, Henan, Shandong, Shanxi, Anhui, Jiangsu and other provinces, with an area of ​​more than 30 million mu, and a few plots were replanted or destroyed , is a rare serious ...

Problems solved by technology

[0005] The purpose of the present invention is to solve the disadvantages that the current conventional sowing can not achieve the purpose of clearing the wheat stalks in the sowing rows, and the method of manually removing the wheat stalks in the sowing rows before the emergence of corn to prevent and control the two-spot moth is labor-intensive and time-consuming, and cannot be popularized in a large area. The method for mechanized removal of sowing row wheat stalks can be achieved through the following steps:
