Problems solved by technology

For a long time, most hemp bamboo forests have been in a state of natural extensive management, with low yield and poor quality
Even if there are operating farmers, most of the fertilization of bamboo forests is chemical fertilizers. There is no scientific guidance on the ratio of nutrients and the amount of fertilizers. Fertilization is relatively blind, resulting in poor quality of bamboo forests, and a decline in bamboo shoot production, quality and economic benefits, which not only wastes manpower and material resources. and financial resources, and often cause environmental pollution due to blind fertilization, which affects the sustainable development of the hemp bamboo industry

Embodiment 1

[0028] The special fertilizer for hemp bamboo is prepared from the following raw materials by weight: 460 parts of fermented cow dung, 275 parts of urea, 90 parts of monoammonium phosphate, 174.5 parts of potassium sulfate and 0.5 part of sodium selenite.

[0029] The preparation method is as follows:

[0030] Step 1) Mixing of raw materials: take fresh cow dung with a water content of about 90%, add bamboo chips in a ratio of 3:1 by weight of fresh cow dung and bamboo chips, and use a mixer to mix evenly to obtain a water content of about 74%. fermented cow dung;

[0031] Step 2) Stacking fermentation: Add 1.5% of the fermenting bacteria to the cow dung obtained in step 1) and mix to form a pile, then ferment. When the temperature reaches above 60°C, turn it once every 1-2 days. Among them, the biological strain adopts the "Sanju Lishengyuan" microbial fertilizer produced by Fujian Zhangzhou Sanju Biotechnology Co., Ltd., which contains thermophilic and heat-resistant Cellul...

Abstract

The invention provides a special fertilizer for Dendrocalamus latiflorus Munro, wherein the special fertilizer is prepared from the following raw materials: fermented cow dung, urea, monoammonium phosphate, potassium sulfate and sodium selenite. According to the present invention, the produced special fertilizer is rich in organic matters, wherein the content of the organic matters is more than 25%; the produced special fertilizer has complete nutrients of nitrogen, phosphorus and potassium, wherein the effective nutrients of nitrogen, phosphorus and potassium are more than 25%; the produced special fertilizer is rich in selenium; with the application of the produced special fertilizer in soil, the advantages of long-lasting fertilizer efficiency, high nutrient utilization rate, no livingbacteria, no egg, no harmful substance, no pollution and good quality can be achieved; the special fertilizer can increase the yield and improve the quality of bamboo shoots; the yield per mu of the bamboo shoots obtained after the special fertilizer application is increased by more than 60% compared with the Dendrocalamus latiflorus Munro forest with no fertilizer application; with the special fertilizer, the contents of soluble saccharides, proteins, amino acids, vitamin C and other nutrients of bamboo shoots are significantly improved, the cellulose content of bamboo shoots is decreased significantly, and the taste is crisp and tender; and the preparation method is simple, and is suitable for large-scale promotion.

Description

technical field [0001] The invention relates to planting hemp bamboo, in particular to a special fertilizer for hemp bamboo and a preparation method thereof. Background technique [0002] Dendrocalamus Latiflorus Munro (Dendrocalamus Latiflorus Munro) is one of the most widely cultivated bamboo species in southern my country. It is a large clustered bamboo species of the genus Dendrocalamus in the subfamily Bambusoideae of Poaceae (Poaceae) and mainly produces shoots. Bamboo bamboo grows fast, has a long shoot period, high yield, and excellent quality of bamboo shoots. Its bamboo shoots are rich in nutrients, contain a lot of crude fiber, more than 20 kinds of amino acids and trace elements necessary for human body. They are delicious and are deeply favored by people. There are a large number of dried bamboo shoots and cans on the market, even exported to Japan, Europe and the United States and other countries. It has a very broad market, and Mazhu is fast-growing and high-y...
