CuLtivation method for seLenium enriched potatoes

Abstract

The invention discLoses a cuLtivation method for seLenium enriched potatoes. The method comprises the specific steps of seLecting and processing potato seeds, seLecting soiL, appLying base fertiLizer,performing seed sowing, appLying fertiLizer after seed sowing, and controLLing excessive growth. Loamy soiL parceLs with the fLat terrain, deep and thick pLough Layers and Loose soiL Layers or rice stubbLe fieLd bLocks with Loose soiL are seLected, the content of seLenium in soiL is measured, organic seLenium fertiLizer is evenLy appLied to soiL, and the using amount of organic seLenium fertiLizer to the parceLs in each mu is within 10-15 kiLograms. WhiLe the organic seLenium fertiLizer is appLied, 80 kiLograms of nitrogen-phosphorus composite fertiLizer is appLied to parceLs of each mu. HoLeappLied fertiLizer is appLied within 20-25 days after seed sowing, tuber formation fertiLizer is appLied within 55-60 days after seed sowing, and expansion fertiLizer is appLied within 70-80 days after seed sowing. By cuLtivating the seLenium enriched potatoes, the content of seLenium of potatoes is increased, the potato quaLity is improved, and the economic benefits of the potatoes are improved;meanwhiLe, seLenium intake of the human body is increased due to the edibLe seLenium enriched potatoes, human diseases caused by seLenium deficiency are reduced, the human Life is proLonged, and thepotato functionaLization is achieved.

Description

technical field [0001] The invention relates to a method for cultivating potatoes in the field of cultivation technology, in particular to a method for cultivating selenium-enriched potatoes. Background technique [0002] The potato is a herbaceous perennial plant in the family Solanaceae, whose edible tubers are the fourth most important food crop globally. The main potato producing countries are China, Russia, India, Ukraine, the United States, etc., and China is the country with the largest total potato production in the world. Therefore, the yield of potato has important significance for improving grain yield, and the cultivation method of potato has crucial effect for improving potato yield. [0003] Selenium is an essential trace element in the human body and has multiple biological functions, such as preventing and treating Keshan disease, Kaschin-Beck disease, improving the body's immunity, and delaying aging. Simultaneously, because the selenium content of most an...
