Potato medical fertilizer and preparation method thereof

Abstract

The invention relates to a potato medical fertilizer. The raw materials of the special fertilizer include, by weight, 45-45.8 parts of potassium sulfate, 17.3-18 parts of urea, 13.6-14.4 parts of monoammonium phosphate, 8-8.8 parts of sheep manure, 5-5.9 parts of flaxseed cakes, 2.8-3.5 parts of sodium polyacrylate, 1.8-2.5 parts of zinc sulfate, 0.9-1 part of Curzate(Du Pont), and 0.05-0.10 partof Antracol bactericide. The formula proportion of each component in the special fertilizer is the formula which is screened according to the abundance and deficiency index of nitrogen, phosphorus, potassium and trace elements in potato fields in Gansu Province and the ratio of potatoes to absorb the nitrogen, phosphorus and potassium, so that problems of large potato plantation areas, long continuous cropping years, serious soil-borne diseases, low organic matter content of the potato fields and poor water retention capacity can be solved; and the yield of the potatoes can be greatly enhancedby adopting the potato medical fertilizer prepared from the above components. A preparation method of the potato drought-resistant special fertilizer is also related.

Description

Technical field [0001] The present invention relates to the technical field of agricultural chemical fertilizers, in particular to a special fertilizer for potatoes; the present invention also relates to a preparation method of the above special fertilizer.
