Biological green manure for promoting high yield of longan and preparation method thereof

Abstract

The invention relates to the technical field of longan cultivation, and particularly relates to a biological green manure for promoting high yield of longan and a preparation method of the biological green manure. The green manure comprises a green manure base material, a soil conditioner and a sterilizing and pest expelling substance, wherein the mass ratio of the green manure base material to the soil conditioner to the sterilizing and pest expelling substance is (50-60):(10-15):(3-8). The main ingredients of the green manure base material are astragalus smicus, radix isatidis residues, soybean straw, washing water of rice, citrus peel, passion fruit peel and green tea residues; and the base material is rich in nitrogen, phosphorus and potassium to meet the growth requirement and the fruit bearing requirement of longan. The soil conditioner is further added in the biological green manure, so that the soil is further conditioned, and the fruit cracking rate of longan is reduced. The sterilizing and pest expelling substance in the biological green manure is mainly from a plant source, is easy to degrade under light conditions, is an environment-friendly and efficient sterilizing and pest expelling substance, and does not cause pesticide residues.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of longan cultivation, in particular to a biological green manure for promoting high yield of longan and a preparation method thereof. [0003] 【Background technique】 [0004] Longan (scientific name: Dimocarpus longan), also known as longan, lychee slave, sub-lychee, and swallow egg, is a Chinese fruit; the longest life span can reach more than 400 years. Because of its sweet, delicious, and high nutritional value, it is loved by people. Guangxi is a subtropical region and has unique advantages in cultivating longan. However, in recent years, in order to increase the yield of longan, many growers have continuously applied inorganic fertilizers to fertilize and promote longan during the planting process; using inorganic pesticides to prevent and control longan diseases and insect pests, although the short-term effect is significant, can bring fruit growers Huge economic benefits, but in the long run...

Problems solved by technology

However, in recent years, in order to increase the yield of longan, many growers have continuously applied inorganic fertilizers to fertilize and promote longan during the planting process; using inorganic pesticides to prevent and control longan diseases and insect pests, although the short-term effect is significant, can bring fruit growers Huge economic benefits, but in the long run, the disadvantages of inorganic fertilizers and pesticides are becoming more and more prominent; long-term application of inorganic fertilizers will cause soil compaction due to the lack of humus, which will affect the nutritional value of the soil, resulting in an acid-base imbalance in the land. Longan is prone to cause fruit cracking; and the application of pesticides can drive away pests and diseases, but since most of the pesticides come from inorganic chemical components and cannot be degraded in nature, they will be enriched in the longan pulp. If the pulp is dried, the content will be greater, and the It will seriously affect the health of human beings. Therefore, the following problems need to be solved in the longan planting process: (1) solve the problem of soil compaction caused by the application of chemical fertilizers, longan is easy to crack fruit, and the quality is not good; (2) solve the problem of using pesticides to sterilize , Deworming, causing pesticide residues to threaten human health
