Abstract

The invention relates to a fertilization method for high-yield cultivation of winter wheat in fluvo-aquic soil areas in northern Henan, which takes into account environmental capacity, comprising the following steps: (1) crushing all summer corn stalks and returning them to the field; hm 2 , to contain P 2 o 5 Meter, base application of phosphorus fertilizer 90 ~ 180 kg / hm 2 , to contain K 2 O meter, basal application of potassium fertilizer 80 Kg / hm 2 , the plowing depth is 15~18cm; (2) Sowing wheat seeds in mechanical drills, the sowing depth is 3~5cm, and the plant density at the seedling stage is 2.6 to 2.8 million plants / hm 2 (3) In terms of N content, topdressing nitrogen fertilizer at the jointing stage is 76-125 kg / hm 2 After that, irrigate in time. The invention takes the wheat-soil-fertilizer system as the research object, fertilizes rationally, seeks high-yield wheat and environment-friendly chemical fertilizer input, scientifically prevents non-point source pollution, and promotes the coordinated development of agricultural production and environmental protection.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a method for high-yield cultivation and fertilization of winter wheat in a fluvo-aquic soil area in northern Henan, which takes environmental capacity into consideration. Background technique [0002] Fluvo-aquic soil is the soil formed by river sediments affected by groundwater movement and farming activities. It is named after the phenomenon of night tide. It belongs to semi-aqueous soil. Its main characteristics are flat terrain and deep soil layer. It is mainly distributed in river alluvial Plains, delta floods and low terraces. Northern Henan is located in the middle of the North China Plain. It is the main wheat producing area in Henan Province. Its soil is mainly fluvo-aquic soil. It has always been an important winter wheat production base in my country. Doing a good job in its wheat production is of great significance to ensuring my country's food se...
