Embodiment 1

[0016] A kind of rice no-till direct seeding method provided by the invention comprises the following steps successively:

[0017] (1) Weeding: Before the winter solstice, first spray herbicides to kill the weeds, let the surface of the land freeze naturally, and loosen the ground surface; spray the herbicides again around the Ching Ming Festival in the second year to kill the grass, and water to keep the field moist after the grass dies. The ungerminated weeds regenerate; before the beginning of summer, spray herbicides to kill weeds. After 9 days of weeding, after the grass dies, water the land for 10 days to soften the land;

[0018] (2) Breeding: Soak the grain seeds in lime water for 12 hours to pick up and accelerate germination, then mix the germinated grain seeds with root powder, so that the seeds take root quickly, and air in the shade for 4 hours;

[0019] (3) Sowing: About 2 weeks before the rice harvest in mid-to-late October, artificially sow the seeds evenly int...

Embodiment 2

[0024] A kind of rice no-till direct seeding method provided by the invention comprises the following steps successively:

[0025] (1) Weeding: Before the winter solstice, first spray herbicides to kill the weeds, let the surface of the land freeze naturally, and loosen the ground surface; spray the herbicides again around the Ching Ming Festival in the second year to kill the grass, and water to keep the field moist after the grass dies. The ungerminated weeds regenerate; before the beginning of summer, spray herbicides to kill weeds. After 9 days of weeding, after the grass dies, water the land for 8 days to soften the land;

[0026] (2) Breeding: Soak the grain seeds in lime water for 10 hours, pick them up to accelerate germination, then mix the germinated grain seeds with root powder, so that the seeds take root quickly, and dry in the shade for 2 hours;

[0027] (3) Sowing: About 2 weeks before the rice harvest in mid-to-late October, artificially sow the seeds evenly in...

Abstract

The invention discloses a paddy rice no-tillage direct-sowing method characterized in comprising the steps of (1) weeding, (2) seed treatment, (3) sowing, (4) secondary weeding, (5) fertilizing, and (6) secondary sowing. With the method, soil organism growth and development are promoted, soil biodiversity is enriched, chemical fertilizer use is reduced, farmland non-point source pollution is reduced, labor and effort are saved, agricultural planting efficiency is improved, and paddy rice quality is improved.

Description

technical field [0001] The invention relates to a method in the technical field of agricultural planting, in particular to a no-tillage direct seeding method for rice. technical background [0002] The core problem of sustainable utilization of cultivated soil in my country is the depletion and deterioration of soil organic matter, which directly leads to the decline of soil function. Soil organic matter is the basic material of the soil system, which affects the physical and chemical properties of the soil, and controls microbial activity through the C and N sources provided, thus playing an important role in soil fertility. Good soil physics, chemistry and biology The properties, as well as the productivity of soil, are closely related to the content and characteristics of soil organic matter. Due to the lack of organic matter, the cycle conversion and utilization rate of various nutrients are low, the soil ecosystem is out of balance, and the soil fertility is reduced. ...
