AI Technical Summary

Technical Problem

The soil in the reclaimed land has low organic matter content, lack of available nitrogen, and poor microbial activity. Traditional fertilization techniques cannot effectively match the nutrient requirements of wheat, resulting in low yields and soil degradation, exacerbating labor shortages. Existing technologies have failed to achieve a precise ratio of fast-acting and slow-release fertilizers and synergistic effects between organic and inorganic fertilizers, leading to an imbalance between environmental and economic benefits.

Method used

The method of applying coated urea in combination with organic fertilizer involves mixing coated urea, ordinary urea, organic fertilizer, humic acid, and phosphorus and potassium fertilizer into the base fertilizer and applying it in a certain proportion. By combining the biodegradability of polyurethane coating material and the soil activating effect of humic acid, precise nutrient supply and soil improvement can be achieved.

Benefits of technology

It significantly increases wheat yield, enhances soil organic matter content and microbial activity, reduces nitrogen fertilizer utilization and environmental pollution risks, is easy to operate and has significant economic benefits, achieving the goals of increasing production and efficiency while being environmentally friendly.

Abstract

The present application belongs to the technical field of re-cultivated land yield-increasing fertilization methods, and particularly relates to a re-cultivated land wheat yield-increasing and fertilization method of combined application of coated urea and organic fertilizer, comprising: S1, base fertilizer preparation and application: preparing base fertilizer 3-5 days before wheat sowing, applying the base fertilizer into the re-cultivated land and plowing or rotary plowing; the base fertilizer is prepared by fully mixing coated urea, ordinary urea, organic fertilizer, humic acid, phosphorus fertilizer and potassium fertilizer, the mass ratio of the coated urea to the ordinary urea is 0.8-1.2:1, the total application amount of the coated urea and the ordinary urea is 12-18 kg / mu of pure nitrogen, the application amount of the organic fertilizer is 80-120 kg / mu, and the application amount of the humic acid is 2-5 kg / mu; S2, sowing and field management: sowing in time after the base fertilizer application, and performing conventional field management during the growth period. In summary, the present application realizes yield increase and efficiency increase, soil fertilization and environment friendliness, and is suitable for large-area popularization and application.
