Abstract

The invention belongs to the technical field of agricultural cultivation and discloses a rice straw returning wheat rooting seedling strengthening and fineness maintaining cultivation method. The cultivation method comprises the steps of rice straw fertilizer concomitance, deep tillage and burying of straw, heavy dressing of base fertilizer, rotary tillage raking, excavation of three ditches, accurate and fine sowing, line spacing hole forming, timely topdressing and comprehensive regulation. The phenomenon that wheat seedling emergency is affected due to the fact that rice straw floats on the earth surface or a shallow soil layer is avoided through rice straw fertilizer concomitance, returning and deep burying; ventilation and oxygen aeration of roots of wheat are promoted through mechanical wheat row-sowing excavation of air holes, strong seedling growth at roots is promoted, and later-period lodging is avoided; due to air hole dressing of fertilizer, rapid root absorption and seedling strengthening are promoted; due to air hole irrigation, drought control, wet dissipation and flooded field drainage, the fine growth environment of wheat is maintained.

Description

technical field [0001] The invention relates to the technical field of agricultural cultivation, in particular to a cultivation method for maintaining high-quality roots and strong seedlings of wheat by returning rice straw to the field. Background technique [0002] Wheat is an important food crop and industrial raw material in my country. It is rich in protein, carbohydrates, vitamins and mineral elements. It is a raw material for biscuits, bread and other food industries. It has high nutritional value and is widely used. [0003] In Huainan and Huaibei rice and wheat areas, wheat is harvested in the second year of sowing in autumn and winter. During this period of time, there is relatively little rain, and the surrounding ditches lack water, so normal irrigation is often impossible, which is not conducive to the growth of wheat; 3. High soil moisture is not conducive to the growth of wheat, and often causes rotten roots and dead seedlings due to lack of oxygen in the root...
