Abstract

The invention discloses a compound fertilizer for improving stress resistance of Chinese yams. The compound fertilizer is prepared from the following components in parts by weight: 15 to 25 parts of plant straws, 5 to 10 parts of activated sludge, 5 to 10 parts of livestock and poultry excrement particles, 5 to 11 parts of pine needles, 10 to 15 parts of saw dust, 3 to 6 parts of a microbial agentand 10 to 20 parts of an inorganic fertilizer. According to the compound fertilizer, cellulose nanofiber grafted polyacrylamide gel and nano-hydroxyapatite are used as carriers, and urea, ammonium phosphate, monopotassium phosphate and monocalcium phosphate are used as active components. The invention also discloses a preparation method of the compound fertilizer. The compound fertilizer is goodin slow-release effect, can effectively improve the stress resistance of the Chinese yams, provides nutrients required by the growth of the Chinese yams, and further improves the yield and the qualityof the Chinese yams; and the preparation method is simple and low in cost.

Description

technical field [0001] The invention relates to the field of yam planting, in particular to a compound fertilizer for improving the stress resistance of yam and a preparation method thereof. Background technique [0002] Yam is the underground tuber of Dioscorea yam, which is a traditional medicinal and edible plant in my country. Yam contains vitamins, protein, starch, free amino acids and other nutrients, and some minerals such as calcium, phosphorus and iron are also extremely rich; the functional active ingredients include polysaccharides, polyphenols, saponins, allantoic Cholesterol, ergosterol, choline, etc., have various physiological functions such as anti-oxidation, anti-tumor, lowering blood fat, regulating intestinal flora, enhancing body immunity, etc., and are widely used in functional food, health care products and pharmaceutical industries . [0003] Yam is widely planted in my country and has various varieties. It is an ideal promotion project for the devel...
