Macadamia nut green peel matrix organic fertilizer and preparation method thereof

Abstract

The invention relates to the technical field of planting, in particular to macadamia nut green seedcase matrix organic fertilizer. The organic fertilizer is mainly prepared from bean dregs, corncob powder, macadamia nut green seedcase extract, EM fungicide, carpesium abrotanoides extract, pomegranate peel extract, fructus cnidii extract and cortex phellodendri extract. The organic fertilizer provided by the invention can provide sufficient fertilizer efficiency for the growth of the macadamia nuts and enhance the disease resistance of the roots of the macadamia nuts through the mutual cooperation of the raw materials and the cooperation of the scientific preparation method.

Description

【Technical field】 [0001] The invention relates to the field of planting technology, in particular to a macadamia green bark matrix organic fertilizer and a preparation method thereof. 【Background technique】 [0002] Macadamia is a high-grade economic crop in the tropics and subtropics. Macadamia nuts are rich in nutrients, with an oil content of 70%-79%. They are rich in unsaturated fatty acids and rich in protein, calcium, phosphorus, iron, vitamin B1, vitamin B2 and 8 kinds of essential nutrients for human body. amino acid. At the same time, the monounsaturated fatty acid in macadamia nut oil can reduce the content of low-density lipoprotein cholesterol in the blood, and has high medicinal value for the treatment of atherosclerosis, cardiovascular diseases, diabetes, and tumors. [0003] However, because the macadamia tree has a shallow root system and is not resistant to wind, it is suitable for planting on hills or flat land below an altitude of 1200m. In addition, the ...

Problems solved by technology

[0003] However, because the macadamia tree has a shallow root system and is not resistant to wind, it is suitable for planting on hills or flat land below an altitude of 1200m. In addition, the applicant found that the shallow root system of the macadamia tree is likely to make its roots vulnerable to insect damage, resulting in fruit tree disease. disease, low yield, poor quality of nuts, and a series of problems. At present, the macadamia nut fertilizer in the prior art is mainly based on the nutrient content in the fertilizer, and does not take into account whether the fertilizer used can solve the problem caused by the shallow root system. After the occurrence of pests and diseases, the pests are often eliminated by spraying pesticides. Not only is the effect not good, but the drugs will also reduce the organic matter content in the soil where the planting site is planted, and even cause pesticide residues in the nuts.

[0004] In addition, since macadamia nuts are planted in humid and rainy areas such as tropical and subtropical regions, they are often planted in southern regions such as Guangxi and Yunnan in my country. After years of research, the applicant found that Phytophthora camphora is easy to breed in the soil where macadamia nuts have been planted for many years due to wet soil. , Dispora fungi and other fungi are susceptible to macadamia stem canker disease. After infection with stem canker, the cortex of the infected part of the tree becomes hard, and then sags, the cortex and xylem become discolored, black jelly oozes, the bark cracks, and the leaves Chlorosis, leaf drop and fruit drop, and in severe cases, the trunk will dry up and even die
