Problems solved by technology

At present, most of the tea tree rows are fertilized by ditches and fertilization between rows of tea trees, which requires labor and costs about 300 yuan per mu. Since the rows of mature tea gardens are basically covered by tea tree branches and leaves, some roots and tea branches are easily damaged during the operation.

Abstract

The invention relates to a special compound fertilizer for grown tea as well as a preparation method and an applying method of the tea, and belongs to the technical field of agricultural fertilizers. The compound fertilizer comprises the components in parts by weight as follows: 70 parts-140 parts of monoammonium phosphate, 280 parts-380 parts of ammonium sulfate, 400 parts-600 parts of an organic fertilizer, 40 parts-120 parts of potassium sulphate, 5 parts-25 parts of liquid ammonia and 100 parts-200 parts of a filler. The special compound fertilizer has the benefits as follows: tea trees cannot suffer from a nutrient deficiency symptom, the content of active ingredients in the tea, particularly, the content of free amino acid, can be remarkably increased, and the quality of the tea is improved further.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and in particular relates to a special compound fertilizer for mature tea and its preparation method and application method. Background technique [0002] Fertilizer is the material basis for increasing tea production and improving quality. However, at present, tea fertilizers are very chaotic. There are many single fertilizers used, and some organic fertilizers are used alone and the amount of application is seriously insufficient, resulting in stagnant tea production and difficult to improve tea quality. The use of single chemical fertilizers can cause soil compaction in tea gardens and reduce fertility. It can also cause tea tree deficiency, affecting the yield and quality of tea leaves. There are also special fertilizers such as flue-cured tobacco and so on. [0003] Tea garden soil is different from common dryland soil. The mature tea garden soil forms three parts of soil w...
