Control measures of wheat with spike and no seed

Wheat is one of the staple foods of human beings. it has a long history of planting in China, and the planting area is also very extensive. In the process of wheat planting, the phenomenon of spike and seedless is becoming more and more serious, which seriously affects the yield and quality of wheat and harms the planting income of farmers. So how to prevent and cure the phenomenon that wheat has spikes and no seeds? Let's get to know it with the editor.

1. Select superior varieties

Good varieties are the guarantee of high yield of wheat. It is suggested that growers should choose varieties that have been approved by the national or provincial varieties and are suitable for local planting. Before planting, we should first go through a small area of experimental sowing and then spread and apply in a large area to ensure that the variety is suitable for local planting and ensure the yield and quality.

2. Prevention of cold injury

According to the winter and spring habits of millet, we should scientifically arrange the appropriate sowing time and amount, cultivate strong seedlings, promote the early development of seedlings, maintain a reasonable population structure in winter and spring, and promote the strength of individual plants. only in this way can we ensure the normal development of flower spikes and the improvement of seed setting rate. It is suggested that farmers spray chemicals that can improve the stress resistance of wheat at the jointing stage, which can obviously improve the stress resistance of wheat and lay a solid foundation for high yield and high quality in the later stage.

3. Strengthen the field management

It is necessary to strengthen field management and reduce flower degradation habits, which can effectively increase the number of grains per spike of wheat. Potassium dihydrogen phosphate, brassine and boron fertilizer can be sprayed from jointing stage to flowering stage, so as to supplement nutrition for plants and improve the pollination ability of wheat. timely prevention of wheat sheath blight, white ear disease, total erosion disease and other diseases.

4. Scientific use of drugs

The use of drugs should be selected according to the occurrence of diseases and insect pests in the wheat field in order to avoid waste and drug injuries. in the chemical dilution, it is recommended to choose the secondary dilution method to avoid uneven solution and cause wheat drug damage. In the dispensing must be in accordance with the instructions, should not increase the amount of medicine at will, when spraying to avoid flowering, spraying should choose before 10:00 or after 4 p.m., avoid the high temperature period at noon, so as not to occur drug damage. In the use of herbicides, it is also necessary to choose the type, time and dosage of herbicides, and note that no herbicides should be used after the jointing stage of wheat.
