Abstract

The invention discloses a long-acting slow-release fertilizer for planting cannabis sativa and a manufacturing method of the long-acting slow-release fertilizer. The fertilizer comprises the following raw materials, by weight part, 40-60 parts of cannabis sativa residue, 30-50 parts of silkworm excrement, 15-25 parts of peanut bran, 5-10 parts of humic acid, 20-30 parts of urea, 15-20 parts of potassium chloride, 12-18 parts of calcium superphosphate and 10-15 parts of a coating material. The coating material comprises the following raw materials, by weight part, 4-6 parts of re-dispersible latex powder, 3-5 parts of sepiolite and 3-5 parts of nanometer calcium carbonate. Inorganic fertilizers and organic fertilizers are combined to prepare the long-acting slow-release fertilizer. The long-acting slow-release fertilizer is comprehensive in nutrition, reasonable in matching ratio and consumption of elements, high in utilization rate of the fertilizer, good in slow-release effect, long in fertilizer effect, and low in cost. Through the long-acting slow-release fertilizer, the yield of cannabis sativa is increased, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of plant planting, in particular to a slow-release long-acting fertilizer for planting hemp and a preparation method thereof. Background technique [0002] Hemp (Cannabis sativa L. subsp. Sativa), also known as marijuana, belongs to the genus Moraceae. In my country, it is mainly distributed in Guangxi, Anhui, Henan, Hebei, Shanxi, Shandong, Heilongjiang, Inner Mongolia, Shaanxi, Sichuan and other places. The stem bark fiber of hemp is long and tough, which can be used to weave linen or thread, make rope, weave fishing nets and make paper. The fruit of hemp is called "huomaren" or "hemp kernel" in traditional Chinese medicine. It is flat in nature and sweet in taste. The oil content of hemp seed is 30%. The oil extracted from it is the famous longevity oil and hemp oil. Blood pressure, cholesterol and other diseases have special curative effect. Huomahua is called "Mabo", and it is mainly used to treat b...
