Embodiment 1

[0017] A control method for subterranean pests that can be used for returning wheat corn stalks to the field, comprising the following steps:

[0018] (1) Mechanically pulverize the harvested corn stalks, perform deep plowing and burying, apply fertilizers, and sow wheat after land preparation; the wheat is treated with a suspended seed coating agent; field management is carried out, and the wheat is harvested after it is mature;

[0019] (2) Wheat stalks are pulverized while harvesting wheat, deeply plowed and buried, and corn is sown with a no-tillage seeder, and the corn is treated with a suspended seed coating agent; fertilization is applied at the corn seedling stage and bell mouth stage;

[0020] The active ingredients in the suspension seed coating agent are dinotefuran and dinotefuran; and the weight percentage of the active ingredients is 5% of dinotefuran and 35% of dinotefuran.

Embodiment 2

[0022] A control method for subterranean pests that can be used for returning wheat corn stalks to the field, comprising the following steps:

[0023] (1) Mechanically pulverize the harvested corn stalks, perform deep plowing and burying, apply fertilizers, and sow wheat after land preparation; the wheat is treated with a suspended seed coating agent; field management is carried out, and the wheat is harvested after it is mature;

[0024] (2) Wheat stalks are pulverized while harvesting wheat, deeply plowed and buried, and corn is sown with a no-tillage seeder, and the corn is treated with a suspended seed coating agent; fertilization is applied at the corn seedling stage and bell mouth stage;

[0025] The active ingredients in the suspension seed coating agent are dinotefuran and dinotefuran; and the weight percentage of the active ingredients is 15% of dinotefuran and 25% of dinotefuran.

Embodiment 3

[0027] A control method for subterranean pests that can be used for returning wheat corn stalks to the field, comprising the following steps:

[0028] (1) Mechanically pulverize the harvested corn stalks, perform deep plowing and burying, apply fertilizers, and sow wheat after land preparation; the wheat is treated with a suspended seed coating agent; field management is carried out, and the wheat is harvested after it is mature;

[0029] (2) Wheat stalks are pulverized while harvesting wheat, deeply plowed and buried, and corn is sown with a no-tillage seeder, and the corn is treated with a suspended seed coating agent; fertilization is applied at the corn seedling stage and bell mouth stage;

[0030] The active ingredients in the suspension seed coating agent are dinotefuran and dinotefuran; and the weight percentage of the active ingredients is 30% of dinotefuran and 10% of dinotefuran.

Abstract

The invention provides a prevention and control method for underground pests in wheat-maize rotation fields with returned straws. The prevention and control method provided by the invention has the advantage that by adoption of a suspended seed coating agent to treat maize or wheat seeds, underground pests can be effectively prevented.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a method for preventing and controlling underground pests that can be used in wheat moons as straw returning to the field. Background technique [0002] Crop straw is a ubiquitous organic agricultural waste resource. How to dispose of crop straw scientifically and efficiently has become an urgent problem for agricultural production and environmental protection. Straw contains a large amount of organic matter, nitrogen, phosphorus, potassium and other nutrients. Therefore, direct or indirect return of straw to the field can establish a good soil ecosystem and is also an important measure to improve the basic fertility of farmland soil. Although straw returning to the field is an important way to improve the fertility and productivity of farmland soil and the comprehensive utilization efficiency of straw, it will inevitably bring some negative effects, such as aggravation of ...
