Problems solved by technology

2. The proportion of ecological water used in paddy fields is too large
3. The utilization efficiency of paddy field water is too low, 0.6-0.9 liters / m3 in southern rice areas, and 0.4-0.8 liters / m3 in northern rice areas
Covering upland rice with plastic plastic film can increase production and income, but the plastic film is difficult to decompose in the natural environment, causing secondary disasters of white pollution

Abstract

The invention provides a rice dry-farming direct-seeding planting method, which is characterized by comprising the following: a, a step of preparing land, which is to level and harrow land before sowing, replenish pre-sowing water and keep soil moisture between 75 and 85 percent; b, a step of sowing, which is to uniformly sow rice seeds on the land finished in a step a, wherein the amount of seeds per each Mu of land is 2.5 to 5.4 kg; c, a step of earthing up, which is to earth up at a height of 1.5 to 3 centimeters after sowing is finished; d, a step of compacting, which is to compact after earthing up; and e, a step of spraying film, which is to add 0.03 to 0.06 kilogram of 2-methyl-4-chlorophenoxy acetic acid serving as herbicide to 60 to 80 liters of water, mix and stir the materials and uniformly spraying the obtained product on the compacted land so as to finish the dry farming and direct seeding of rice. The rice dry-farming direct-seeding planting method can leave out two work links of cultivating seedlings and transplanting. After multifunctional degradable liquid mulching film is sprayed on ground, effective accumulated temperature can be increased; rice water shortage is alleviated; the physical and chemical properties of soil are improved; microbial activity is improved; the decomposition and release of soil organic substances are accelerated; the transfer of effective nutrient to plants is accelerated; and the photosynthetic efficiency and nutrient conveying rate of rice are improved. The method has the advantages of ensuring exuberant tillering tendency, low positions of tillering knobs and numerous big ears, saving water by 50 to 70 percent and increasing yield by about 10 percent.

Description

technical field [0001] The invention belongs to a method for planting crops, in particular to a method for direct seeding of rice in dry farming. Background technique [0002] my country's per capita water resources are only 1 / 4 of the world's per capita, ranking 110th in the world, and are listed by the United Nations as one of the 13 water-poor countries in the world. The 15 provinces, municipalities, and autonomous regions in northern my country have an annual per capita water resource of 1,141 cubic meters, and the 16 southern provinces, municipalities, and autonomous regions have an annual per capita water resource that is three times that of the north. The area of ​​the groundwater funnel in the north is 1.5 billion square meters. The reality of severe water shortage in the north has caused the Yellow River to dry up, lakes to dry up and shrink, vegetation to degrade, oases to disappear, and land desertification and salinization to accelerate. By 2030, my country's t...
