Planting method for high-yield selenium-rich wheat

Abstract

The invention discloses a planting method for high-yield selenium-rich wheat, belonging to the field of crop planting. The planting method comprises the following concrete steps: land selection, soil preparation, seed selection and seed dressing, seeding, and field management and harvesting. With the planting method for wheat provided by the invention, a seed-dressing agent used for seed dressing provides sufficient nutrients for seedlings, promotes development of a wheat root system, and can improve the seedling emergence rate and lodging-resistant, disease-resistant and pest-resistant abilities of the wheat; the seed-dressing agent contains a selenium element, and during spraying of a liquid fertilizer in the step of field management, by adopting a manner of diluting the seed-dressing agent, the fertilizer efficiency is improved, and the application field of a seed-dressing fertilizer is increased; in the aspect of using a fertilizer, by cooperative application of a great amount of elemental fertilizers, organic fertilizers and medium-element fertilizers, the usage amount of a nitrogen fertilizer is greatly reduced; the planted wheat is rich in selenium element which is easy to be absorbed by human body; meanwhile, the wheat has good quality and full grains; and the yield of the wheat is averagely increased by 147.3 jin per mu.

Description

technical field [0001] The invention belongs to the field of crop planting, and in particular relates to a high-yield planting method of selenium-enriched wheat. Background technique [0002] Wheat has been planted in my country for more than 5,000 years. Wheat is the main type of wheat in my country. Wheat is widely planted in China. From south to north, from plains to mountainous areas, wheat is cultivated in almost all agricultural areas. At present, my country's wheat planting area and total output are second only to rice, ranking second in my country's food crops. Wheat is the staple food of the people in northern my country. It has been an important food for nourishing the human body since ancient times. It is rich in nutrients such as starch, fat, protein, vitamins, phosphorus, calcium and iron. It contains proteolytic enzymes and various vitamins. It can enhance the body's disease resistance and prevent and treat various diseases including cancer. [0003] Selenium ...

Problems solved by technology

However, with the continuous changes of natural conditions, temperature and diseases, etc., the harvest of wheat has been troubled.

In order to produce wheat with high protein content, farmers use irrational chemical fertilizers, which leads to soil compaction, and low nitrogen utilization rate. The large loss of nitrogen fertilizer causes eutrophication of water bodies and seriously pollutes the river environment.

With the improvement of production conditions in the vast rural areas, the yield level of wheat has increased, but the increase in planting density and biomass will inevitably lead to the deterioration of the micro-ecological environment of the canopy, and the impact of major diseases and insect pests such as sheath blight and black germ disease. Occurs continuously, seriously affecting the high and stable yield of wheat, and reducing the processing and nutritional quality of wheat
