Abstract
The invention relates to a winter wheat high-yield cultivation fertilizing method considering environment capacity in a moisture soil region of the north Henan province. The method includes the following steps that (1) summer maize straw is completely smashed and returned to the field, according to measurement based on N content, basal application of nitrogen fertilizer ranges from 76 kg / hm<2> to 125 kg / hm<2>; according to measurement based on P2O5 content, basal application of phosphate fertilizer ranges from 90 kg / hm<2> to 180 kg / hm<2>; according to measurement based on K2O content, basal application of potash fertilizer is 80 kg / hm<2> and the plowing depth ranges from 15 cm to 18 cm; (2) wheat seeds are mechanically sown in lines, the sowing depth ranges from 3 cm to 5 cm, and the plant density ranges from 2,600,000 stocks / hm<2> to 2,800,000 stocks / hm<2> in the seedling stage; (3) according to measurement based on N content, after 76 kg / hm<2> to 125 kg / hm<2> of nitrogen fertilizer is dressed in the elongation stage, seedlings are watered in time. According to the method, a wheat-soil-fertilizer system serves as a research object, fertilizer is reasonably applied, the chemical fertilizer input capable of meeting the requirements for high wheat yield and environment friendliness is searched for, non-point source pollution is scientifically prevented and treated, and harmonious development of agricultural production and environmental protection is facilitated.
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 account. 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 security...
