Abstract

The invention discloses a dry direct seeding planting method for rice. The method sequentially comprises the steps of rotary tillage, stubble burying, leveling, fertilization, seeding, primary pressing, watering, film mulching, soil covering and secondary pressing in a planting process. Seedling raising and transplanting links are omitted. Especially when spring sowing is started in May in northern areas, sufficient sunlight exists, but the ground temperature is not enough, and the problem is effectively solved through the dry direct sowing planting method for the rice. The rice automatically drills a mulching film and grows out of the ground, the mulching film is tightly attached to seedlings, and moisture and heat are preserved to the maximum extent. 80% of the surface evaporation capacity is also blocked by the mulching film; and meanwhile, the transpiration amount of rice plants is also reduced, and compared with hydroponic rice, the technology has the advantage that the water consumption can be reduced by more than 50%. In addition, the seedlings covered by the mulching film grow in a soil layer with good soil moisture content, sufficient oxygen and high ground temperature, so that the development of root systems is promoted.

Description

technical field [0001] The invention belongs to the field of rice planting, in particular to a rice planting method using dry direct seeding. Background technique [0002] At present, rice prefers high temperature, high humidity, and short sunshine, and it does not have strict requirements on soil, and paddy soil is the best. The minimum temperature for seedling germination is 10-12°C, and the optimum temperature is 28-32°C. The daily average temperature of tillering stage is above 20℃, and the optimum temperature for ear differentiation is about 30℃; low temperature prolongs the differentiation of branches and spikelets. The optimum temperature for heading is 25 to 35 °C. The optimum temperature for flowering is around 30°C. If it is lower than 20°C or higher than 40°C, fertilization will be seriously affected. Relative humidity of 50 to 90% is appropriate. However, in real life, rice is grown outdoors, and the temperature depends on the weather. Because of the weather,...
