Embodiment 1

[0029] Liangping pomelo organic fertilizer is prepared from the following raw materials by weight: 812 parts of mixed cow dung, 102 parts of urea, 25 parts of monoammonium phosphate, 60 parts of potassium sulfate, and 1 part of ammonium molybdate.

[0030] The preparation method is as follows: S1) Mixing of raw materials: take fresh cow dung with a water content of 80-90%, add bran powder according to the ratio of fresh cow dung and auxiliary materials of 3:1, and mix evenly with a mixer to obtain a water content of about 60%. S2) stacking fermentation: add 1.0% to 2.0% of fermenting bacteria to the cow dung obtained in S1) and mix to form a heap, then ferment, and when the temperature reaches above 60°C, stir every 1 to 2 days once. Among them, the biological strain adopts the "Sanju Lishengyuan" microbial fertilizer produced by Fujian Zhangzhou Sanju Biotechnology Co., Ltd.; S3: adding inorganic nutrients: when the fermentation temperature drops to 35-40°C during the prepara...

Abstract

The invention discloses organic fertilizer and a preparation method thereof. The special organic fertilizer is prepared by taking cow dung as a foundation, adding components including urea, ammonium dihydrogen phosphate, potassium sulfate and ammonium molybdate and fermenting. The organic fertilizer is used for planting Liangping pomelo and the yield and quality of the Liangping pomelo are easily improved. The preparation method of the special organic fertilizer, disclosed by the invention, is simple and has controllable quality; an operation technology is easy to grasp and three wastes are not generated in a production process so that the special organic fertilizer has no pollution to the environment.

Description

technical field [0001] The invention relates to an organic fertilizer, in particular to a special organic fertilizer for Liangping pomelo and a preparation method thereof. Background technique [0002] Liangping pomelo, together with Guangxi Shatian pomelo and Fujian Wendan pomelo, is one of the three famous pomelo in China. It is produced in Liangping County, Chongqing City, with a planting area of ​​130,000 mu. It belongs to the pillar industry of Liangping County, and its output and quality are related to Liangping’s economic development. When Liangping pomelo is ripe, the fruit is huge, rich in aroma, juicy and sweet, and rich in nutrition. It is called "natural canned fruit". However, most pomelo farmers blindly use chemical fertilizers to increase production, resulting in a decline in the quality and taste of the pomelo fruit. Liangping pomelo matures after frost and goes on the market later. Affected the quality and reputation of Liangping pomelo fruit. [0003] Man...
