Time-saving, labor-saving and income-increasing wheat "no-tillage sowing" technology

No-tillage sowing of wheat

Wheat "no-tillage sowing" technology means that after corn harvest, the straw is uniformly spread on the surface after crushing, without rotary ploughing and deep loosening, and sown with special sowing machine fertilizer in the suitable sowing period of wheat. After years of experiments, the following advantages of this technology are summarized:

1. To realize the "four provinces": Rotary ploughing and deep ploughing are not carried out before wheat sowing, which reduces the number of operations, reduces power consumption, saves labor, time, labor and money, and saves 50 yuan per mu of ploughing investment.

2. Water saving and drought resistance: straw is spread on the ground surface, there is no soil dry cracking in winter and spring, the soil is steady, and the evaporation and loss of soil water are reduced.

3. Keep out the cold and increase temperature: straw mulching is like covering a quilt for wheat seedlings and soil, which is beneficial for wheat seedlings to survive the winter safely and reduce the death of overwintering seedlings; the ground temperature rises quickly in spring, and the growth period can be advanced by 2 or 3 days.

4. Improve fertilizer efficiency: sowing and fertilization is completed at one time, concentrated and deep application is achieved, the volatilization and leaching loss of fertilizer are effectively avoided, and the utilization rate of fertilizer is improved.

5. Ventilation and light transmission: no-tillage planting adopts row sowing with 5 cm sowing width, broadening row spacing, increasing tiller space, more wheat tillers, good ventilation and light transmission between rows, and less occurrence of diseases and insect pests.

6. Increase production and income: wheat planted under no-tillage has strong comprehensive resistance, less diseases and insect pests, stout stems, large spikes and many grains, delayed maturity, prolonged filling period by 3-4 days, yield increased by 5%-10%, and cost-saving and efficiency-increasing per mu was 150-200 yuan.
