Problems solved by technology

The following problems exist in the management of cassava fertilization: (1) The fertilization is random, the fertilizer efficiency of the input fertilizer is poor, and the fertilizer utilization rate is low; And the amount of medium and trace elements is insufficient, which does not meet the law of cassava's demand for nutrients; (3) There is no compound fertilizer specially developed for cassava, and the absorption of nutrients during the growth process of cassava has a certain law, according to the law of cassava's nutrient absorption. Reasonable formula helps to improve the utilization rate of chemical fertilizers
Relevant statistics show that the loss rate of chemical fertilizers used in the cassava industry is as high as 40%, resulting in a large waste of energy and environmental pollution, and the pollution of groundwater is becoming more and more serious

Abstract

The invention discloses a Manihot esculenta Crantz compound fertilizer, which consists of the following effective components in parts by weight: 8.0-12.0 parts of nitrogen, 7.0 parts of phosphorus pentoxide, 16.0-20.0 parts of potassium oxide, 2.0-5.0 parts of calcium, 0.5-3.0 parts of magnesium and 0.5 part of boron. The invention additionally discloses a preparation method for the compound fertilizer. The preparation method has the advantages that the method is simple, the cost is low, and the prepared compound fertilizer not only can meet the demands of Manihot esculenta Crantz for nitrogen, phosphorus and potassium, but also can meet the demands of the Manihot esculenta Crantz to trace elements such as calcium, magnesium and boron. By applying the compound fertilizer disclosed by the invention during Manihot esculenta Crantz culture, the yield and the quality of the Manihot esculenta Crantz can be improved, the utilization ratio of the compound fertilizer is improved and the environmental pollution is reduced.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a compound fertilizer and a preparation method thereof. Background technique [0002] Cassava ( Manihot esculenta crantz ) is a shrub-like perennial crop whose roots are rich in starch and can be eaten and fed, and can also be used as a raw material for bio-oil. In recent years, in order to meet the ever-increasing demand for bioenergy, the planting area of ​​cassava in my country has increased year by year. At present, the planting area has exceeded 10 million mu, mainly planted in southern my country such as Guangxi, Hainan, Yunnan and Guangdong. With the continuous increase of cassava planting area, the total demand for chemical fertilizers is gradually increasing, so the high utilization rate of cassava fertilizer has also attracted people's attention. The following problems exist in the management of cassava fertilization: (1) The fertilization is random, the fertilizer efficien...
