Embodiment 1

[0034]Embodiment 1: select a suitable piece of land to remove weeds and make high-selenium corn production site, mix the nano-selenium plant nutrient with the base fertilizer, and evenly spread it on the surface of the soil layer. The nano-selenium plant nutrient consumption is according to Use 15kg / mu. Rotate tillage immediately after fertilization to a depth of 15-20cm. Break up soil clods to keep the soil particle size below 1cm. Dig a ditch every 1.2m with a depth of 15-20cm. The sowing depth is about 5cm, and about 3500 corns are sown per mu. Irrigate once 5 days after emergence, and the amount of irrigation should be kept at 60-80% of the maximum water holding capacity in the field. Carry out another irrigation treatment at the booting stage of corn, and the irrigation amount is the same as above. During the grouting period, the nano-selenium plant nutrient was supplemented once according to the amount of 5kg / mu, and an irrigation treatment was performed, and the irriga...

Embodiment 2

[0035] Embodiment 2: select a suitable plot to remove weeds and make high-selenium wheat production site, mix the nano-selenium plant nutrient with the base fertilizer, and evenly spread it on the surface of the soil layer. The consumption of the nano-selenium plant nutrient is according to Use 15kg / mu. Rotate tillage immediately after fertilization to a depth of 15-20cm. Break up soil clods to keep the soil particle size below 1cm. Dig a ditch every 1.2m with a depth of 15-20cm. The sowing depth is about 5cm, and 10 kg of wheat seeds are sown per mu. Irrigate once 5 days after emergence, and the amount of irrigation should be kept at 60-80% of the maximum water holding capacity in the field. Carry out another irrigation treatment at the booting stage of wheat, and the irrigation method is the same as above. During the grouting period, the nano-selenium plant nutrient was supplemented once according to the amount of 5kg / mu, and an irrigation treatment was performed, and the i...

Abstract

The invention discloses a farmland planting method of high-selenium crops. The method is characterized by comprising the following steps: (1) uniformly mixing a nano selenium plant nutrient with a base fertilizer, applying the mixture to the surface of farmland soil and plowing so that the nano selenium plant nutrient is uniformly distributed on a plowing layer; (2) uniformly seeding on the farmland soil according to the crop types, and wetting and irrigating the soil surface layer 5-10 days after the crop seedling emerges; and (3) performing conventional field management on the crop according to different crop types until the crops are mature. According to the invention, the high-selenium crops can be cultivated, the selenium content is stable, and the proportion of organic selenium is high.

Description

technical field [0001] The invention provides a farmland planting method for high-selenium crops, aiming at cultivating crops with high and stable selenium content, and the proportion of organic selenium is greater than 80%, which can be widely used in feed and food additives. Background technique [0002] Selenium, the symbol of the element is Se. Scientists at home and abroad have conducted a lot of research on selenium and human health. The results show that although the content of selenium in human tissues is small, it has an indispensable role in human health just like iron, zinc, iodine and other trace elements. The role of neglect. Experts believe that selenium has important functions such as improving the body's immunity, eliminating free radicals, protecting the optic nerve, protecting the heart and liver, and preventing the production of toxic substances in the body. Human Keshan disease, liver disease, anemia, coronary heart disease, Kashin-Beck disease, and diabe...
