Problems solved by technology

Wheat needs to absorb trace elements such as manganese, zinc, copper, boron, and molybdenum in the process of growth and development; manganese deficiency: wheat leaves are soft and downcast, and sometimes gray spots appear; zinc deficiency: affects wheat tillering and reduces ear formation rate; boron deficiency: Dysplasia of stamens, less pollen, lower seed setting rate; molybdenum deficiency: short wheat plants, small spikes, few grains, low yield
[0003] In the process of wheat planting, excessive application of chemical fertilizers not only leads to soil compaction, but also low nitrogen utilization rate, a large amount of nitrogen fertilizer loss, serious environmental pollution, and lack of nutrient elements lead to poor quality of wheat

Abstract

The invention discloses a winter wheat cultivation method. The method comprises the following steps: a plot with flat terrain, deep soil layer and fertile soil is selected; the plot is deeply plowed and finely harrowed; drill-seeding is carried out with an equal space of 15cm, wherein a seeding amount per Mu is 5.6-7.2kg; seedling checking and reseeding are carried out 10 days after seeding; in early March when winter wheats turn green, spring harrowing is carried out in time, wherein a harrowing depth is 3-5cm, and harrowing is carried out continuously 2-3 times on saline-alkali lands; first irrigation is carried out when the winter wheats turn green, and second irrigation is carried out 7-10 days after the first irrigation; when the wheats reach a full stand, 0.08% ammonium molybdate and fulvic acid are sprayed to leaf surfaces; during a wheat jointing stage, 150kg of urea is applied per Mu; and during a wheat filling stage, 0.2% sodium selenite is sprayed. According to the invention, with fulvic acid, crop antioxidant enzyme activity can be improved, normal crop photosynthesis is maintained, and plant growth is promoted. Serious adverse effects of nitrogen fertilizer pollution and pesticide residue in high-quality wheat production are reduced. Trace elements of boron, zinc, molybdenum and rich selenium are provided, such that wheat yield and quality are improved.

Description

technical field [0001] The invention relates to the technical field of crop planting, in particular to a planting method of winter wheat. Background technique [0002] Wheat is one of the most important food crops in the world, and more than one-third of the population takes wheat as staple food. The planting area of ​​wheat in my country is second only to rice, with an annual planting area of ​​about 30 million hectares, accounting for one-fifth of the country's total grain crop area. Nitrogen accounts for 2.2% of dry weight in wheat grains and is an important component of cell protoplasm. Phosphorus accounts for 0.7-0.9% of dry weight in wheat grain and is a component of nucleoprotein. Potassium accounts for 0.5-0.6% of the dry weight in wheat grains, and it promotes the synthesis and operation of carbohydrates. Pure nitrogen: 2.75-3.23 kg, converted to ammonium bicarbonate 46.8-54.9 catties; phosphorus pentoxide: 0.88-1.39 kg, converted to calcium superphosphate 106-16...
