Abstract

The invention discloses a fertilizer for the potato tuber growth period. The fertilizer is prepared from, by weight, 20-40 parts of urea, 20-30 parts of potassium phosphate, 10-30 parts of shrimp andcrib shell powder, 20-30 parts of chicken manure, 40-60 parts of rice straw, 20-30 parts of egg white paste, 10-15 parts of peanut shells, 40-60 parts of plant ash, 1-3 parts of EM fungicide, 5-10 parts of microelements, 1-3 parts of vitamin, 0.5-1 part of auxin and 20-40 parts of additive, wherein the additive is prepared from Arabic gum, decomposed coal, charcoal and potassium polyacrylate. Theinvention further discloses a preparing method of the fertilizer for the potato tuber growth period. Through mutual cooperation of all substances, the release speed of all elements is adjusted while rich nutrients are provided for potatoes, so that the fertilizer satisfies the fertilizer need characteristic of the potato tuber growth period, the water retention is high, the soil environment and nature can be improved, and the fertilizer promotes the growth of tubers.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a fertilizer for potato tuber growth period and a preparation method thereof. Background technique [0002] Potatoes are the fourth largest food crop in the world and a staple food with important edible value and processing value in China. The crop has a high water demand and is sensitive to water deficiency, which can hinder or even severely damage the normal development of potatoes. However, about 60% of the potatoes in China are planted in arid and semi-arid areas, and there are very few potatoes with irrigation conditions. [0003] Potato tuber growth period is the period when potatoes require the most water. At this time, the tubers rapidly expand, accounting for about 50% of the total water demand. At this time, potatoes need more fertilizer, especially potassium fertilizer. People often add fertilizers with good water retention properties during the growth of potato ...
