Fertilization method for increasing selenium content in flaxseed and production method of flaxseed

Abstract

The invention discloses a fertilization method for increasing selenium content in flaxseed and a production method of the flaxseed. A selenium element microelement fertilizer is selected as a nutrient substance which is rich in selenium in the flaxseed, the fertilization way is that foliage spraying is performed on flax plants before 11:00 AM and after 15:00 PM in sunny and airless weather, and when the selenium element microelement fertilizer is used, a recommended using quantity for 667m<2> of the selenium element microelement fertilizer is firstly dissolved in a small amount of water, then 30kg of water is added for uniform stirring, and a sprayer is used for uniform spraying. The fertilization quantity, the fertilization period, the number of fertilization times and the fertilization effects are as follows: 1000ml-1500ml of the selenium element microelement fertilizer is sprayed in 667m<2> of flax during green fruit period, and the selenium content in the flaxseed can achieve 0.2mg / kg-0.3mg / kg; 2000ml-2500ml of the selenium element microelement fertilizer is sprayed in 667m<2> of the flax during the green fruit period, and the selenium content in the flaxseed can achieve 1.5mg / kg-1.8mg / kg; and the selenium element microelement fertilizer is respectively sprayed once during squaring period and the green fruit period of the flax, the using quantity in each 667m<2> is 2000ml-2500ml, and the selenium content in the flaxseed can achieve 2.1-2.9mg / kg.

Description

technical field [0001] The technical invention relates to improving the content of essential trace elements in crop products, enhancing the nutrition and health care function of foods rich in trace elements, and the technical field of nutritional biology research. It is a technical method that can significantly increase the selenium content in flax seeds and the production of flax seeds method. Background technique [0002] According to relevant literature reports. Thirty years ago, the World Health Organization announced that selenium is an essential trace element in humans and animals. It has therapeutic and preventive effects on liver cancer, gastric cancer, gastric adenocarcinoma, prostate cancer, cardiovascular disease, neuropathy, tumor and other diseases. At the same time, selenium is also an antidote for heavy metals, which can combine with heavy metals such as lead, cadmium, and mercury, so that these toxic heavy metals are not absorbed by the intestinal tract and...
