Fertilization method for increasing selenium content of flax seeds and production method of flax seeds

Abstract

The invention discloses a fertilizing method for increasing the content of selenium in flaxseeds and a production method for flaxseeds. Micro element fertilizer containing selenium is selected as nutrient substance of selenium-rich flaxseeds, the fertilizing way is as follows: fertilizer spraying to leaf surfaces of flax before 11:00 Am and 15:00 Pm in a clear and calm weather, during the use, firstly, the micro element fertilizer containing selenium, with the dose recommended for 667 m<2>, is resolved by a little water, and then added with 30 kg water for stirring, and a sprayer is used for uniform spraying. The fertilizing amount, the fertilizing time, the fertilizing frequency and the fertilizing effect are as follows: in the green fruit stage of the flax, if 1000 ml to 1500 ml of micro element fertilizer containing selenium is sprayed for 667 m<2>, the content of the selenium in flaxseeds can reach 0.2 mg / kg to 0.3 mg / kg, if 2000 ml to 2500 ml micro element fertilizer containing selenium is sprayed for 667 m<2>, the content of the selenium in flaxseeds can reach 1.5 mg / kg to 1.8 mg / kg; and the micro element fertilizer containing selenium is sprayed for one time in each of the green fruit stage and the bud stage, 2000 to 2500 ml micro element fertilizer containing selenium is sprayed for 667 m<2>, and the content of selenium in flaxseeds can reach 2.1 to 2.9 mg / 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...
