Blueberry fruit tree dedicated fertilizer using rabbit excrement as main raw material and preparation method of fertilizer

Abstract

The invention belongs to the technical field of fruit tree fertilizers and relates to a blueberry fruit tree dedicated fertilizer and a preparation method thereof. The blueberry fruit tree dedicated fertilizer using rabbit excrement as the main raw material is a solid organic fertilizer which is prepared from the following raw materials in mass percent: 40-60% of rabbit excrement, 30-50% of straws, 3-6% of nitrogenous fertilizer, 1.5-2% of phosphatic fertilizer and 1.5-2% of potassic fertilizer. The preparation method for the blueberry fruit tree dedicated fertilizer comprises the following steps: fermenting the mixture of the rabbit excrement and the straws, adding the nitrogenous fertilizer, the phosphatic fertilizer and the potassic fertilizer, culturing liquid mycorrhizal fungi, and the like, so that the blueberry fruit tree dedicated fertilizer provided by the invention is prepared. According to the blueberry fruit tree dedicated fertilizer, sulphur is not added, so that the soil pH is prevented from being excessively low or excessively high; the mycorrhizal fungi is added to promote growth of bacilli of the blueberry root system; according to the characteristics of the rabbit excrement raw material, the straws and other ingredients such as ammonium sulfate, monoammonium phosphate and potassium sulphate are added to ensure uniformity and stability of the product; the preparation method for the blueberry fruit tree dedicated fertilizer has the advantages that the process is simple, the raw material is easy to obtain, the rabbit excrement and straws are used as main raw materials, and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of fruit tree fertilizers, and relates to a special fertilizer for blueberry fruit trees and a preparation method thereof. Background technique [0002] Blueberry is an evergreen or deciduous shrub of the family Ericaceae (Vaccinium), with a bell-shaped corolla and a lower ovary. The berries are black, brown or red, often covered with white fruit powder. As a new fruit tree, the cultivation management of blueberry is obviously different from other fruit trees. Blueberry has few root hairs, shallow roots, and the root group is distributed in shallow soil. It is suitable for growing in soil with an organic matter content of more than 3%, and the soil pH is required to be 4.5-5.5. [0003] Blueberry is an oligotrophic species, and the amount of fertilizer required for blueberry is far lower than that of other fruit trees or berries. The content of N, P and K in the fertilizer should not be too high or too low...

Problems solved by technology

However, due to the large difference in the organic matter content of various organic materials, and the large difference in the original pH of different soils, the adaptability of the above-mentioned organic fertilizers is very poor.
