Description

Technical Field

[0001] The invention relates to the technical field of organic fertilizers, and in particular to an organic fertilizer special for sweet dragon bamboo and a preparation method thereof. Background Art

[0002] Sweet dragon bamboo is commonly known as "sweet bamboo" or "sweet shoots" in Yunnan. It is a large clumping bamboo species of the genus Bambusoideae, a traditional superior bamboo species for bamboo shoots and one of the important economic bamboo species. It is widely distributed in Yunnan from western Yunnan to southern Yunnan. Sweet dragon bamboo is a common cultivated bamboo species, with an altitude of 380 to 1900 meters. Its fresh shoots are of excellent quality, tender meat, no bitterness, sweet and delicious, especially suitable for fresh eating; its bamboo material has good mechanical properties and is an excellent raw material for making bamboo floors, furniture, farm tools, daily necessities, artificial boards, pulp and other industrial and agricultural products. At present, there is a large demand for sweet dragon bamboo seedlings in the market, so accelerating its seedling propagation is of great significance to expanding the planting area and meeting market demand.

[0003] In modern agriculture, the growth and development of crops cannot be separated from the assistance of fertilizers. According to different chemical compositions, fertilizers can be divided into chemical fertilizers and organic fertilizers. Chemical fertilizers refer to all inorganic fertilizers and slow-release fertilizers produced by industry. Organic fertilizers are a type of natural fertilizers that are accumulated on site or directly buried in rural areas using various organic materials such as animal and plant residues or human and livestock excrement. They are also called farmyard fertilizers. Organic fertilizers have many advantages. They contain a large amount of organic matter, have obvious soil improvement and fertilization effects, and the nutrients they contain are fully balanced; the fertilizer effect lasts for a long time and organic fertilizers come from nature. There are no chemical synthetic substances in the fertilizers, and long-term application can improve the quality of agricultural products. Chemical fertilizers can only provide inorganic nutrients for crops. Long-term application will have adverse effects on the soil, making the soil "more and more greedy". The nutrients they contain are single, and long-term application is likely to cause nutrient imbalance in the soil and food. In addition, chemical fertilizers have a short and fierce fertilizer effect, which is easy to cause nutrient loss and pollute the environment. Improper application will also reduce the quality of agricultural products. However, organic fertilizers also have some disadvantages, such as low nutrient content and the need for large-scale application. And there are few reports on organic fertilizers specifically used for sweet dragon bamboo in the prior art. Therefore, providing an organic fertilizer specifically used for sweet dragon bamboo with a small application amount and high nutrient content is a technical problem that the prior art needs to solve urgently. Summary of the invention

[0004] The purpose of the present invention is to provide an organic fertilizer special for sweet dragon bamboo and a preparation method thereof.
