Dry farming direct seeding planting method of rice

Abstract

The invention discloses a dry farming direct seeding planting method of rice, which comprises the steps of preparing sprinkling irrigation equipment: the lifting micro-sprinkling irrigation equipment is buried under to-be-planted ground for 30-40cm; processing a field: straws of last stubbles of crops on the to be planted ground are cut into sections, the lengths of the straw sections are 2-20cm, the straw sections are broadcast in soil, a base fertilizer is applied on the soil, and the soil is subjected to ploughing and rotary tillage; preparing rice seeds and seeding: the selected rice seeds are sown on the processed soil uniformly, and then the soil is compacted; and performing sprinkling irrigation: the lifting micro-sprinkling irrigation equipment buried under the ground is used for irrigating the soil sown with the rice seeds, and the water content of the surface of the soil is 40-60%. Therefore, the precision irrigation to the crops is realized; excess water accumulation in the rice field is avoided; and the utilization ratio of water resources is increased. In addition, the straws are turned into organic fertilizers with the passage of time; straw turnover is realized indeed; the method contributes to improving the yield and quality of grains; and environmental pollution due to straw burning is avoided.

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] Rice is the main crop planted in our country. So far, the cultivation method of flood irrigation is generally adopted, which consumes a lot of water. However, my country is a country with relatively scarce water resources. At the same time, due to climate change, there are some rice-growing areas in our country. The lack of water has led to a decline in local rice. [0003] The technique of using mulch to plant rice in dry fields to save water and increase production is a relatively new technique, and these techniques have also been popularized and applied. However, there are certain defects in these technical methods: more drip irrigation belts and plastic films are required, and the cost is higher. At the same time, if the plastic film covering method is used for rice dry field planting all the year ...

AI Technical Summary

Problems solved by technology

However, there are certain defects in these technical methods: more drip irrigation belts and plastic films are required, and the cost is higher. At the same time, if the plastic film covering method is used for rice dry field planting all the year round, more plastic film fragments will be produced in the field soil. Great soil pollution

Growers often burn the straw, which causes serious environmental pollution

In addition, because the straw returning to the field has not been solved well, and the land is not or rarely applied with farmyard manure and organic fertilizer, the land becomes more and more barren, and the more chemical fertilizers are applied, the loss is also serious. Moreover. Growing in water, rice pests and diseases occur seriously, and the amount and frequency of pesticide use are increasing. At the same time, due to the backwardness of rice irrigation technology and the shortage of labor force, the increase in rice yield per unit area has been small for many years.
