Breeding and cultivation method of lodging-resistant and high-yield wheat

Abstract

The invention discloses a cultivation method of lodging-resistant and high-yield wheat. The method includes the steps: planting the wheat on October 8-24; applying mechanical fertilizers to the wheatto serve as base fertilizers, and topdressing the mechanical fertilizers at a jointing stage; irrigating the wheat, and preventing diseases, insect pests and weeds. The planting density of the wheat is 120 thousand to 160 thousand basic seedlings per mu, irrigation is performed before the wheat is sown, field moisture is not lower than 70%, winter irrigation is performed after planting of the wheat, over-wintering water is sufficiently irrigated once, safety over-wintering is ensured, hazards of spring frost, late spring coldness and middle and late drought are prevented, and high and stable yield is achieved. The bred wheat has the advantages that young seedlings are half-procumbent, leaf blades are slightly wide and bottle green, growth vigor is strong, seedling-stage growth is steady, cold resistance is good, tillering ability is medium, ear bearing tiller rate is high, plant types are semi-compact, flag leaves are uplifted, spike layers are tidy, plants are high, stem elasticity isgood, lodging-resistant capability is high, spikes are rectangular, awns are long, shells and grains are white, grains are powdery and full, commodity nature is good, wheat yield per spike is high and the like.

Description

technical field [0001] The invention belongs to the field of wheat seed preparation and relates to a breeding and cultivation method for lodging-resistant and high-yield wheat. Background technique [0002] Wheat is one of the three major grains, almost all of which are used for practical use, and only about one-sixth is used as feed. Mesopotamia is the first area in the world to cultivate wheat. China is one of the countries that first planted wheat in the world. At present, wheat During the planting process, due to climatic factors or improper cultivation measures, a large area of ​​wheat lodging occurs, seriously affecting the maturity of wheat, resulting in a phenomenon of reduced yield. Contents of the invention [0003] The object of the present invention is to provide a breeding method for lodging-resistant and high-yield wheat, which has a high spike rate, neat ear layers, good stalk elasticity, strong lodging resistance, and meanwhile, the grains are silty, plump ...
