Problems solved by technology

[0004] For cassava fertilizers, domestic manufacturers or units currently seldom develop special compound fertilizers. Most of them use conventional compound fertilizers or a mixture of nitrogen and potassium fertilizers. Most organic fertilizers use low organic fertilizer content, which is not conducive to the growth of cassava.

Abstract

The present invention discloses a special manihot esculenta crantz compound fertilizer and a production method thereof, wherein the nutrients (the representation method refers to the GB18877-2009 organic-inorganic compound fertilizer national standard) comprise, by weight, more than or equal to 32% of total nutrient (N+P2O5+K2O), more than or equal to 15% of organic matters, 5-10% of compound amino acids, 0.1-0.5% of medium elements, 0.04-0.1% of trace elements, and 0.5-8% of pyrite ash. According to the present invention, the special manihot esculenta crantz compound fertilizer is prepared by carrying out pre-treatment, granulation and magnetization, such that nitrogen, phosphorus, potassium and other nutrients required by manihot esculenta crantz growth can be provided, the medium-trace elements are contained, and the organic matters are rich; and with the magnetization treatment, the soil malnutrition caused by continuous cultivation can be improved, the physical properties of the soil can be effectively improved, nutrient absorption of crops can be promoted, the special manihot esculenta crantz compound fertilizer has effects of nitrogen fixation and nitrogen fertilizer utilization rate improving, and the average yield per mu is increased by more than or equal to 15%.

Description

technical field [0001] The invention belongs to the field of crop fertilizers, and in particular relates to an organic-inorganic compound fertilizer for applying cassava and a production method thereof. Background technique [0002] Cassava originated in tropical America and is widely cultivated in tropical and some subtropical regions, mainly in Brazil, Mexico, Nigeria, Bolivia, Thailand, Colombia, Indonesia and other countries. Introduced and cultivated in China in the 1820s, it is now widely distributed in South China, with Guangxi and Guangdong having the largest cultivation areas, followed by Fujian and Taiwan, and a small amount of cultivation in Yunnan, Guizhou, Sichuan, Hunan, Jiangxi and other provinces. Cassava is one of the three major potatoes (cassava, sweet potato, potato) in the world. The main uses of cassava are food, feed and industrial development and utilization. Root starch is one of the main starch raw materials in industry. 65% of the world's total ...
