The organic fertilizer applicable to litchi and longan consists of the following components in parts by weight: 15 to 25 parts of longan pits; 15 to 25 parts of litchi pits; 5 to 10 parts of longan shells; 5 to 10 parts of litchi shells; 5 to 10 parts of bagasse; 2 to 3 parts of kapok; 20 to 25 parts of biogas residue; 3 to 5 parts of pelelith powder. The preparation method of the organic fertilizer includes the following preparation steps: preprocessing, fermentation, refermentation and drying and pelletizing. The invention sufficiently utilizes nitrogen, phosphorus and other nutrient substances which are rich in litchi and longan, coupled with the combination of the pelelith powder and the biogas residue, a large quantity of discarded pits are sufficiently utilized, and therefore the organic fertilizer is environment-friendly and practical.

Description

technical field [0001] The invention relates to the field of agriculture, especially the field of organic fertilizers. Background technique [0002] my country is a large agricultural country. Pesticides and chemical fertilizers play a very important role in agricultural production. With the improvement of people's living standards and health awareness, people attach great importance to the safety of agricultural products, and the demand for pollution-free and green food is increasing year by year. . [0003] Litchi and longan are the "four major fruits in the southern country", and their planting area is in the south, especially in Guangdong and Guangxi. The output is huge, because longan and litchi plants produce a large number of fruits every year, and their pulp has high sugar content and organic matter, which is very important for the fertility of fruit trees. The requirements are particularly high, so fruit farmers apply a large amount of chemical fertilizers to fruit ...

[0003] Litchi and longan are the "four major fruits in the southern country", and their planting area is in the south, especially in Guangdong and Guangxi. The output is huge, because longan and litchi plants produce a large number of fruits every year, and their pulp has high sugar content and organic matter, which is very important for the fertility of fruit trees. The requirements are particularly high, so fruit farmers apply a large amount of chemical fertilizers to fruit trees every year, or some natural fertilizers such as animal manure, but because they do not understand the specific needs of fruit trees for nutrients, the fertilizer effect is not fully utilized, and it also leads to weeds in the orchard.
