Fertilizer applicable to planting of tea tree at seedling stage and preparation method thereof

Abstract

The invention discloses fertilizer applicable to the planting of a tea tree at a seedling stage and a preparation method thereof. The fertilizer is prepared by adopting the following raw materials: coal ash, pulverized coal, bentonite clay, chicken manure, pine needle soil, phosphorus mineral powder, sorghum straw, a rooting agent, 6-10wt% roughly-made amino acid solution, calcium magnesium phosphorus fertilizer, shell powder, ammonium dihydrogen phosphate and an appropriate amount of water. The fertilizer is suitable for the stone soil poor in nutrition, organic matters of the soil can be increased, otherwise, the application of a great amount of inorganic elements can increase the occurrence rate of diseases and insects and increase the toxicity in tealeaves, the rooting agent is mixed with special porous particles, the porosity of the particles has a protection effect for the hormones such as the rooting agent, the hormones are unlikely to decompose under the simulation of the environment, the fertilizer is made into a granular form, the air ventilation is increased, and the rooting of the tea seedling can be promoted.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a fertilizer suitable for planting tea trees at the seedling stage and a preparation method thereof. Background technique [0002] The planting of tea is generally planted in the hilly areas of mountainous areas. The planting soil is brick red soil, red red soil or yellow soil. The earliest tea in the world appeared in southern Sichuan, so the planting conditions of tea trees are mainly in hilly areas. Appropriate, similar to the planting structure of terraced fields. [0003] Tea is a perennial crop harvested several times a year. Young leaves are often picked, so nutrients and water must be supplied in a timely manner. The fog in the mountainous area just meets this requirement, and continuous fertilization is required. The main planting feature is that the main root of the tea tree used for production is kept above 1m, and the lateral roots are in the soil lay...
