Abstract

Various novel techniques are continuously popularized and applied with the continuous increase of the potato plantation scope and area. The invention provides a potato nutrient prepared by yeast hydrolysate, which belongs to the crops plantation field. The invention relates to a preparation method of a potato high-yield nutrient, which is capable of directly and effectively raising the per mu yield of the potato. The yeast has abundant nutrition and is composed of protein, carbohydrate, nucleic acid and other substances without toxicity and hormone, is a good single cell protein resource and contains eight amino acid and 14 mineral matters required by human and animal body, almost all the vitamins, nucleic acid, glutathione and the like. The present invention has the goals of overcoming the technical defects of the like technique and disclosing the preparation method of the potato nutrient prepared by yeast hydrolysate. The potato nutrient is a biological growth promoter for processing and producing potato by using chemical and biological technology according to the biological characteristics of yeast. Reports of crops output increased by using yeast cells in fertilizer and planting industry do not exist at present.

Description

technical field [0001] The invention relates to a method for preparing potato high-yield nutrient, in particular to a method for preparing potato nutrient by using yeast hydrolyzate, which belongs to the field of crop planting. Background technique: [0002] Potato is an important food crop and an important raw material of starch. With the rapid development of starch industry, potato planting is developing rapidly in our country. At present, potatoes are widely planted in various parts of our country. In 2009, the potato output has exceeded 100 million tons. . With the continuous growth of planting scope and area, various new technologies have been promoted and applied, including potato detoxification technology, tissue culture, potato professional organic fertilizer, etc. However, the output of potato planting in my country is relatively low at present. The highest yield can reach 2500kg / mu, and there is no direct and effective method to increase the yield of potatoes per m...
