Production method for selenium-enriched rice

Abstract

The invention relates to a production method for selenium-enriched rice. The production method comprises the following steps: preparing a selenium-enriched organic liquid fertilizer; improving a ricefield when the rice field overwinters; applying the selenium-enriched organic liquid fertilizer to rice from breeding, raising rice seedling and planting processes for management. In the embodiment process, the rice field is improved by means of a biofertilizer formed by combining crop straws, animal feces and chitin and the selenium-enriched organic liquid fertilizer composed of organic selenium,organic matters and chitin when the rice field overwinters. The soil of a used land is conditioned to be neutral with biological bacterial manure, the improving effect of the soil is obvious, and then the selenium-enriched organic liquid fertilizer is sprayed to the land, so that a selenium-free plot is changed to selenium-enriched soil within a short time, and therefore, the phenomenon that a natural high-selenium soil resource at present is extremely scanty is overcome effectively, and selenium-enriched agricultural products are developed quickly. Meanwhile, the prepared selenium-enriched organic liquid fertilizer is low in cost, high in selenium and organic matters and obvious in using effect.

Description

technical field [0001] The invention belongs to the technical field of rice planting, and in particular relates to a production method of selenium-enriched rice. technical background [0002] Selenium-enriched rice grows selenium-rich rice by supplementing selenium when rice is planted. Belonging to functional agricultural products, it is a food rich in selenium and has high nutritional value. Because of the special nutritional value contained in selenium itself, the nutritional value of selenium-enriched rice is higher. Because selenium has the following functions: [0003] 1. Anti-oxidation and anti-aging: Selenium can delay aging, reduce depression, fatigue and other phenomena, improve eyesight, prevent and treat cataracts, and fundamentally improve the quality of life of the elderly. [0004] 2. Protecting and repairing cells: Selenium in the whole cytoplasm can digest and reduce the peroxides produced in the metabolic activities of the body, and protect the cell memb...

Problems solved by technology

However, due to the different selenium content in the soil, there will be great differences in the selenium content in food from different places, which will affect the quality of selenium-enriched rice.

[0013] However, not every place has high-selenium soil. If the selenium content of the soil is below 0.6 mg / kg, it belongs to the selenium-poor soil. According to the research of geologists: 72% of China's areas are selenium-deficient areas, and natural foods such as grains The selenium content is low. In most parts of China, about 700 million people live in low-selenium-deficient areas, and long-term intake of seriously selenium-deficient foods will inevitably cause selenium-deficiency diseases! Therefore, natural high-selenium soil resources are extremely limited, which is why Greatly inhibited the development of selenium-enriched rice
