Water-fertilizer integration-based planting technology for rice drip irrigation direct seeding on dry land

Abstract

The invention discloses a water-fertilizer integration-based planting technology for rice drip irrigation direct seeding on dry land. The technology comprises the following steps: S10, after tillage and raking are conducted in autumn every year, performing fine preparation on soil by using a soil crusher in spring; S20, selecting rice seeds, and performing treatment; S30, performing sowing at theright time through a wide-narrow row hole seeding method, applying base fertilizer, and performing compacting by using a land roller in time; S40, after sowing is conducted for making the rice seeds into a growth period, performing fertilization and / or disease and pest control and / or grass damage prevention and control during the whole growth period, and after closed weeding is conducted, laying drip irrigation belts according to the specifications capable of achieving control of one drip irrigation belt on four rows of rice; and S50, performing harvest timely according to the rice growth period, and performing planting of the next crop of crops. According to the drip irrigation direct seeding planting on dry land, drip irrigation of fertilizer is conducted on rice roots through the drip irrigation belts by using the water-fertilizer integration technology, so that the absorption and utilization rate of water and fertilizer by rice are improved greatly.

Description

technical field [0001] The invention relates to a rice cultivation method, in particular to a rice planting technique for drip irrigation and dry direct seeding, and belongs to the field of crop planting and agronomy. Background technique [0002] Rice is the most important fine grain crop next to wheat in terms of cultivated area and total output. my country's rice planting area accounts for 23% of the world's total rice area, ranking second in the world, and its output accounts for 39% of the global total output, ranking first in the world. At the same time, my country is also a country with severe drought and water shortage. The per capita fresh water resources are only 1 / 4 of the world's average level, ranking 110th in the world, and it is one of the countries with the poorest per capita water resources in the world. However, there are problems such as large water consumption and low water use efficiency in the conventional rice transplanting planting production. The ir...

Problems solved by technology

[0004] In order to achieve the above object, the present invention provides a rice drip irrigation dry direct seeding planting technology based on the integration of water and fertilizer. The water and fertilizer are drip-irrigated to the root of rice through the drip irrigation belt by using the integration of water and fertilizer technology, which can greatly improve the absorption of water and fertilizer by rice. It not only solves the technical problems of seedling cultivation and transplanting, high labor intensity, low fertilizer and water use efficiency in traditional rice cultivation technology, but also solves the problems in the existing dry direct seeding planting technology. Problems of low water and fertilizer absorption and utilization rate and insufficient timely and accurate irrigation range
