Problems solved by technology

Rainwater has a great influence on the occurrence of bean hornworm. If the rainfall is moderate and evenly distributed from June to August, it will be conducive to its occurrence; but if there is too much rain, the occurrence period will be delayed, and excessive drought will also be unfavorable for its occurrence.

Abstract

The invention relates to a method for preventing and controlling clanis bilineata tsingtauica in soybean. Clanis bilineata tsingtauica mainly live in soybean, but also is harmful to mung bean, cowpea, robinia pseudoacacia and the like. Clanis bilineata tsingtauica juveniles eat soybean leaves. Young juveniles leave only netty and incised leaves; while old juveniles with greater appetite can eat whole soybean plants in serious cases, so that the soybean can not bear pods. Rain is a main influencing factor of clanis bilineata tsingtauica, and from June to August, a period when rainfall is moderate and uniform, clanis bilineata tsingtauica emerges quickly; while too much rain will delay the emergence period and too early drought is also unfavorable for the emergence of clanis bilineata tsingtauica.

Description

【Technical field】 [0001] The invention relates to a method for cultivating soybeans, in particular to a method for preventing and controlling the soybean hornworm. 【Background technique】 [0002] The main host of bean hornworm is soybean, and it can also harm mung bean, cowpea, black locust and so on. The bean hornworm feeds on soybean leaves with larvae. Young larvae eat into meshes and notches, and older larvae eat more. Rainwater has a great influence on the occurrence of bean hornworm. If the rainfall is moderate and evenly distributed from June to August, it will be conducive to its occurrence; but if there is too much rain, the occurrence period will be delayed, and it will be unfavorable to its occurrence if it is too dry. 【Content of invention】 [0003] The technical problem to be solved in the present invention is to provide a method for preventing and controlling the soybean hornworm. In order to solve the above technical problem, the technical solution adopted ...
