Oxygenating cultivation method for irrigating rice with micro-nano bubble water

Abstract

The invention relates to an oxygenating cultivation method for irrigating rice irrigation with micro-nano bubble water, belonging to a rice cultivation method. The method comprises the following steps: 1) conditioning a rice seedling bed, thinly sowing seeds, and cultivating strong seedlings tillering; 2) carrying out soil preparation process and deeply applying basal fertilizers before transplanting, and then transplanting young seedlings; 3) using micro-nano bubble oxygenated water to irrigate rice after transplanting, wherein the rice should not be irritated with the water again until the water is naturally consumed to enable transform the field surface to a wetting state, so that repeated alternation between shallow water and wetting can be formed; applying tillering fertilizers within 7-10 days after transplanting the young seedlings; and drying the field in time after the seedlings grow to enough height; and 4) preventing pests and plant diseases in due time, and harvesting the rice when 95% of grains in the entire field are in the yellow ripe state. By using the invention, the root zone oxygen environment of rice is improved, the root system growth development and the function establishment of rice are promoted, raises the absorption efficiency and utilization efficiency of nitrogenous fertilizer for rice are raised, the contents of available nutrients in soil are increased, obviously the low-position tiller proportion of rice at tillering stage is increased so as to improve percentage of earbearing tiller, and can postpone the leaf senescence can be postponed in grain filling stage, thereby obviously raising setting percentage and improving the rice yield.

Description

technical field [0001] The invention relates to a rice cultivation method, in particular to a rice micro-nano bubble water oxygen-increasing high-yield cultivation method using a micro-nano bubble generating device. Background technique [0002] In facility horticulture and dryland drip irrigation at home and abroad, measures such as air pump oxygenation have been widely used to increase dissolved oxygen content in water, increase crop rhizosphere oxygen content, promote root growth, increase yield, and improve water and fertilizer use efficiency. At present, domestic and foreign researches on rice aerobic cultivation are mainly carried out by sun-drying, irrigation methods, cultivation methods or the application of calcium peroxide and other methods for aerobic treatment. Due to the difficulty of technical operation, weather and other reasons, these rice cultivation techniques It is difficult to fully exert the oxygen-increasing effect when it is applied in a large area, so...

Problems solved by technology

At present, domestic and foreign researches on rice aerobic cultivation are mainly carried out by sun-drying, irrigation methods, cultivation methods or the application of calcium peroxide and other methods for aerobic treatment. Due to the difficulty of technical operation, weather and other reasons, these rice cultivation techniques It is difficult to fully exert the oxygen-increasing effect when it is applied in a large area, so it is difficult to better improve the soil aeration condition on the basis of meeting the physiological and ecological water demand of rice, and essentially solve the contradiction between water and air in rice fields
