High-yield, quality-improving and synergistic cultivation method for strong gluten wheat

Abstract

The invention belongs to the technical field of wheat cultivation, and discloses a high-yield, quality-improving and synergistic cultivation method for strong gluten wheat, which comprises the following steps: selecting varieties, combining wide sowing and close planting during sowing, and pressing after sowing; the total application amount of the nitrogen fertilizer is 240-270 kg / hm < 2 >, and meanwhile, 45-75 kg of sulfur fertilizer is applied to each hectare at a time before sowing; nitrogenous fertilizer is applied as base fertilizer before sowing, nitrogenous fertilizer is applied again as additional fertilizer in spring, and the topdressing period is the jointing period; potassium is applied in stages, wherein the base-topdressing ratio of the potassium application amount in the whole growth period of wheat is 5: 5, and the potassium is applied twice before sowing and in the jointing stage; irrigation and post-flowering water control are optimized, wherein water is irrigated in the jointing stage, and water is irrigated in the heading-full heading stage. Compared with a traditional farmer habit mode, the method has the advantages that a reasonable high-yield, quality-improving and synergistic cultivation technology mode is constructed, the yield, nitrogen utilization efficiency and quality of the strong gluten wheat are remarkably improved, meanwhile, the investment of water and nitrogen fertilizer is saved, the production cost of farmers is reduced, and the economic benefits of the farmers are improved.

Description

technical field [0001] The invention belongs to the technical field of wheat cultivation, and in particular relates to a cultivation method for high-yield, high-quality, synergistic and synergistic cultivation of strong-gluten wheat. Background technique [0002] Strong gluten wheat is an important raw material for making high-quality bread, and an important source of flour for processing staple foods such as noodles, instant noodles, and steamed bread. Demand for high-quality strong-gluten wheat is increasing. However, there are prominent problems in the production of synergy between quality, yield and resource utilization efficiency, poor quality stability, low utilization efficiency of water and fertilizer resources, large investment and high cost, which limit the sustainable development of the strong gluten wheat industry. [0003] The yield, grain quality and fertilizer utilization rate of wheat are not only affected by genotype, but also closely related to ecological ...

Problems solved by technology

However, at present, it is very common to irrigate slurry water at the later stage of wheat growth in Huanghuai and northern wheat regions. Late irrigation is not conducive to wheat production, especially under high-yield cultivation conditions. Too late irrigation will increase the risk of wheat lodging, and lodging will cause colony canopy. Poor ventilation and light transmission conditions will reduce the photosynthetic material production capacity and transport capacity of plants, reduce wheat yield and quality and increase production costs
