Method for planting high-yield selenium-enriched rice

Abstract

The invention discloses a planting method for high-yield selenium-enriched rice, and relates to the technical field of rice planting. The planting method comprises the following steps: (1) soil preparation of a rice field; (2) soaking seeds and accelerating germination; (3) raising rice seedlings; (4) rice transplanting; (5) rice topdressing; (6) field management; (7) harvesting the rice. According to the planting method for the high-yield selenium-enriched rice, when the rice field is subjected to soil preparation, the breeding fish ditches are dug for fish fry breeding, a subsequent fish and rice symbiosis mode is facilitated, nutrient soil is prepared in the rice seedling raising process, and nutrition needed by growth of rice seedlings is conveniently provided; rice is planted in equilateral line positions of equilateral triangle or hexagon rice planting areas, staggered planting is carried out between rows, ventilation and light transmission are achieved through the planting mode, the number of effective plants can be increased, and the problems of uneven light and heat and low yield caused by too many plants in a traditional mode are solved; in addition, a proper fish fry breeding space can be reserved.

Description

technical field [0001] The invention relates to the technical field of rice planting, in particular to a method for planting high-yield selenium-enriched rice. Background technique [0002] Paddy rice is a cereal crop belonging to Oryza genus, and the representative species is rice. Selenium-enriched rice is rice rich in the trace element selenium. Rice cultivation is mainly distributed in the Asian monsoon region. The cultivation of rice in the monsoon region has a history of about 7,000 years. Rice is the main food loved by local people, and the rice produced accounts for the vast majority of the world's total rice output. China is the largest rice producing country in the world, and rice cultivation methods are used in the rice production process. [0003] The existing method for planting high-yield selenium-enriched rice has low crop absorption efficiency when selenium fertilizer is applied, which makes the selenium content of rice insufficient and the breeding mode i...

Problems solved by technology

[0003] The existing method for planting high-yield selenium-enriched rice has low crop absorption efficiency when selenium fertilizer is applied, which makes the selenium content of rice insufficient and the breeding mode is single. Therefore, we propose a method for high-yield and rich rice. Selenium rice planting method
