Moisture soil soil-rice single fertilization technology

Abstract

The invention discloses a moisture soil soil-rice single fertilization technology which includes the steps of rice seedling bed preparation, formulated fertilizer preparation, side deep fertilizer applicator adjustment, rice seedling transplanting and fertilization and field management. Preferably, a monitoring and shooting step adopts a plurality of monitoring cameras, and the rice seedling bed preparation includes the steps of plowing and stubbling, shallow rotary tillage and land flattening and watering. Compared with the prior art, the technology has the advantages that zinc fertilizers and silicon fertilizers needed by rice growth are added, requirements of rice for medium trace elements can be met, the used fertilizers are slowly released and can be prolonged to a fertilizer needingcritical period of rice growth to be released, nutrient absorption of rice can be facilitated, a lot of loss of the fertilizers can be avoided, so that influence of the fertilizers on ecological environments is low, single fertilization is implemented by machinery, and the fertilizers are applied onto root areas of rice seedlings in a concentrated manner, so that labor cost is saved while the utilization rate of the fertilizers is higher.

Description

technical field [0001] The invention discloses a one-time fertilization technology for rice in night-flush soil soil, and belongs to the technical field of rice fertilization. Background technique [0002] Rice planted in high sandy soil has poor water and fertilizer retention performance, so in fertilization, it is necessary to fertilize multiple times according to different periods of rice growth. Conventional fertilization mainly includes: base fertilizer, tiller fertilizer (if it is transplanted by machine, it needs to be applied 3 times), Flower-promoting fertilizer and flower-preserving fertilizer. [0003] The traditional fertilization method is not only labor-intensive, but also requires a large amount of fertilizer. Due to poor soil fertility, nitrogen fertilizer loss is serious, and the nitrogen utilization rate is less than 35%. A large amount of nitrogen is partly lost to the river with the water body, and part of it is turned into gas. , run into the air, which...

Problems solved by technology

[0003] The traditional fertilization method is not only labor-intensive, but also requires a large amount of fertilizer. Due to poor soil fertility, nitrogen fertilizer loss is serious, and the nitrogen utilization rate is less than 35%. A large amount of nitrogen is partly lost to the river with the water body, and part of it is turned into gas. , running into the air, which not only causes waste of resources, but also pollutes the soil environment, water environment and atmospheric environment. For this, it is necessary to propose a one-time fertilization technology for night-flush soil and rice.
