Planting method of selenium-rich bananas

Abstract

The invention discloses a planting method of selenium-rich bananas. The planting method comprises the steps of pretreatment of soil, wherein the soil is sterilized with an ultraviolet germicidal lamp and fertilized with selenium-rich organic fertilizer, planting, sunshading to protect seedlings, fertilization and management, intercropping, banana plant infusion, wherein at the beginning of August, a hole is processed in banana plant cauloid base portions downward in a inclined mode at 45 degrees, the liquid outlet of an infusion bottle is connected to an infusion tube, a plug on the other end of the infusion tube is inserted into the processed hole, the infusion bottle is suspended on a banana plant, and the infusion bottle is filled with selenium-rich amino acid nutrition liquid which is prepared from, by weight, 3-5 parts of selenocystine, 2-4 parts of selenomethionine, 4-5 parts of selenocysteine, 5-7 parts of methylselenocysteine, 6-8 parts of selenohomocysteine, 3-5 parts of honey, 2-3 parts of selenosulfate and 300 parts of water, and pest and disease control. The planting method can improve the survival rate of the banana plant, promote absorption of bananas to selenium elements, increase the selenium content of the bananas and remarkably improve the economic benefits of planting bananas.

Description

technical field [0001] The invention relates to the field of banana planting methods, in particular to a planting method of selenium-enriched bananas. Background technique [0002] The different selenium content in the soil will cause great differences in the selenium content in food in various places. If the selenium content in the soil is below 0.6mg / kg, it belongs to the selenium-deficient soil. 72% of my country's land is selenium-deficient or selenium-deficient soil. Long-term intake Serious selenium-deficient foods will inevitably cause selenium-deficiency diseases. At present, the selenium-rich areas that have been discovered in my country include: Fengcheng in Jiangxi, Ping'an in Qinghai, Enshi in Hubei, Ankang in Shaanxi, Kaiyang in Guizhou, Longyou in Zhejiang, Wanyuan in Sichuan, Wanchang in Jilin, Liuhe, etc. However, some of these selenium-enriched areas are small in size, and some areas are accompanied by undesirable minerals such as lead and mercury, which are...

Problems solved by technology

However, some of these selenium-enriched areas are small in size, and some areas are accompanied by undesirable minerals such as lead and mercury, which are not suitable for direct consumption by the human body. A survey conducted by the Chinese Nutrition Society on 13 provinces and cities in my country shows that adult daily The average selenium intake is 26-32 mg, far from the minimum recommended by the Chinese Nutrition Society of 50 micrograms
