Problems solved by technology

At present, there is a lack of mature and effective control measures in production, and there is no specific selective herbicide that can effectively prevent and control the wheat without harming the wheat. It is urgent to control the spread of the wheat.
At the same time, the use of chemical herbicides has the characteristics of endangering human and animal health, polluting the environment, destroying ecological balance, and promoting the emergence of drug-resistant weeds. contradictions, new problems

Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention belong to the protection scope of the present invention.

[0026] A kind of agronomic method for controlling the weeds of winter wheat fields, the agronomic method of the present invention, comprises the following steps:

[0027] 1) Adjust the sowing date: The sowing date of winter wheat is postponed from late September to early October to the middle and late October every year, forming a time difference in sowing time;

[0028] 2) Induce seedling emergence: After the crops are harvested and before the land is plowed again, keep the soil water content to 70%~85%...

Abstract

The invention discloses an agricultural method for controlling Aegilops tauschii weeds in winter wheat fields. The method comprises seeding time adjustment, induction emergence, chemical seedling induction, emergence acceleration, weed killing with flames and rational close planting. The method has the benefits as follows: the method is safe, efficient, environment-friendly and convenient and quick to operate and only takes agricultural measures, no chemical herbicides are used, time and labor are saved, environmental pollution, ecological damage, crop pesticide residues and the like caused by use of chemical herbicides can be effectively reduced, so that green control on Aegilops tauschii in winter wheat fields in the production practice is guided, and the safety of agricultural products is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to an agronomic method for controlling weeds in winter wheat fields. Background technique [0002] Wheat (Triticum aestivum) is one of the main grain crops in my country. The planting area accounts for about 22% of the total grain crop area, and the output accounts for more than 20% of the total grain output. It is the main commodity grain and strategic reserve grain variety in my country. It plays an important role in circulation and consumption, and the development of wheat production is of great significance to the development of my country's national economy and people's lives. [0003] Aegilops tauschii Coss. 2n=14, DD is an annual herbaceous plant belonging to Triticeae and Aegilops of Poaceae. One of the most harmful weeds. This weed competes fiercely with wheat for light, fertilizer, water and other resources, resulting in reduced or even no harvest of wheat....
