Description
Technical field
The present invention relates to agriculture field, particularly a kind of compound manure and preparation method thereof.
Background technology
Cassava (
Manihot esculenta crantz) be shrub shape perennial crop, its piece root contains abundant starch and can eat with feeding, can also be as the raw material of biological oil.In recent years, for satisfying the ever-increasing demand of bioenergy, China's cassava cultivated area increases year by year, and cultivated area surpasses 1,000 ten thousand mu at present, and essential species is implanted in South Chinas such as China Guangxi, Hainan, Yunnan and Guangdong.Along with the cassava cultivated area constantly increases, the chemical fertilizer aggregate demand is also progressively increased, so the cassava fertilizer of high utilization rate has also caused people's attention.Have following problem on the cassava fertilizing management: (1) fertilising is random big, and the fertilizer efficiency that drops into fertilizer is poor, and utilization rate of fertilizer is low; (2) the fertilizer usage quantity is higher, and the nutrient proportioning is unreasonable, and nitrogen phosphorus potassium drops into uneven, potash fertilizer and in, trace element uses quantity not sufficient, do not meet cassava to the nutrient demand rule; (3) do not have to be directed against the compound manure that cassava is developed specially, in the cassava process of growth nutrient absorbing is had certain rules, nutrient absorbing rule is carried out rational formula, help to improve the utilization ratio of chemical fertilizer according to cassava.Relevant statistics shows that the rate of loss of the chemical fertilizer of cassava industry use at present causes the energy to waste in a large number, and causes environmental pollution up to 40%, and phreatic pollution is also more and more serious.
Summary of the invention
In view of this; One of the object of the invention is to provide a kind of cassava compound manure, can satisfy the demand of cassava growth to macroelement nitrogen, phosphorus and potassium and trace elements calcium, magnesium and boron, improves output and the quality of cassava; Improve the utilization ratio of compound manure simultaneously, reduce pollution environment.
For realizing above-mentioned purpose, technical scheme of the present invention is:
Cassava compound manure, the effective constituent of said compound manure be by weight by nitrogen 8-12 part, 7 parts of Vanadium Pentoxide in FLAKESs, potassium oxide 16-20 part, calcium 2-5 part, 0.5 part of composition of magnesium 0.5-3 part and boron.
