Aquatic and dry amphibious planting method for rice

Abstract

The invention discloses an aquatic and dry amphibious planting method for rice, which comprises the following steps of: 1) dry farming: conducting dry farming or dry field conservative farming under the condition of a dry field; 2) ridging: using a ridging machine to complete ridging at one step or using a furrowing machine to open furrows to form a required ridge mode; 3) rice seedling transplanting: filling water into the furrows and transplanting rice seedlings when the water and the surface of the ridges are on the same level; and 4) water management: filling water to the level of the surface of the ridges at a rice seedling transplanting stage; implementing half-furrow water infiltration irrigation at a seedling emergence stage, a green turning stage, a tillering stage, a heading stage, a grain filling stage and all future growth stages; and shifting to a dry farming state when droughts occur, filling running water to replenish water supply at a proper time and filling deep water in rainy seasons to prevent flooding, wherein the stored water is used for preventing droughts. The aquatic and dry amphibious planting method has the advantages that the water can be saved, the pollution can be controlled, the crop yield can be improved, the farming cost can be saved, the agricultural labor productivity can be promoted, and the economic benefit, the ecological benefit and the social benefit can be improved at the same time.

Description

technical field [0001] The invention relates to a paddy and drought amphibious planting method of rice. Background technique [0002] Rice is one of the most important food crops for human beings, and it has a long history of cultivation and consumption. Rice is eaten by half of the world's population, mainly in Asia, southern Europe, and parts of tropical America and Africa. The total output of rice accounts for the third place in the world's food crop output, lower than that of corn and wheat, but it can maintain the lives of a large number of people. [0003] Rice is an amphibious crop of flood and drought. Rice has a set of physiological mechanisms adapted to dry farming under dry farming conditions, and another set of physiological mechanisms adapted to water farming under water farming conditions. Therefore, according to the conditions required for rice growth, that is, water irrigation conditions, rice can generally be divided into paddy rice and dry rice. In order...

AI Technical Summary

Problems solved by technology

Current research shows that changing rice from paddy to dry can save a lot of water, but the yield of dry-fed rice can only reach 80-90% of that of paddy-fed rice at most

Insufficient yield is an important defect of current dry-fed rice

[0007] Moreover, another deficiency in dry rice is that a large amount of cultivation work is required in the planting process, resulting in a significant increase in work intensity, a serious increase in farming costs, and a significant reduction in agricultural labor productivity.

[0008] Therefore, there are some deficiencies in the simple dry farming conditions and water farming conditions, and there is an urgent need for a paddy and dry amphibious planting method of rice in this area, which can solve the problems of huge water consumption, fertilizer waste and environmental pollution of existing paddy rice, and It can solve the problem of insufficient yield of dry rice at present, and can also save farming costs and improve agricultural labor productivity
