Microalgae fertilizer suitable for northern tea leaves

Abstract

The invention relates to the technical field of fertilizers for tea leaves, in particular to a microalgae fertilizer suitable for northern tea leaves, the microalgae fertilizer comprises the following components in parts by weight: 5-10 parts of medium trace element fertilizers, 3-5 parts of nannochloropsis oculata liquid, 2-5 parts of trichoderma viride and 50-80 parts of tea residues. According to the microalgae fertilizer, the nannochloropsis oculata solution, the trichoderma viride and the tea residues are jointly used, so that soil can be effectively improved, and the yield of tea leaves can be increased; the nannochloropsis oculata solution has a nitrogen fixation effect, a biological membrane can be formed after the trichoderma viride and the nannochloropsis oculata solution are mixed, tea leaf effective components such as tea polyphenol contained in the tea residues are acidic substances, the pH of soil can be reduced, media are provided for the nannochloropsis oculata solution and the trichoderma viride, and the promotion effect is achieved; the medium trace element fertilizer is matched so that the fertilizer efficiency is improved, and the soil quality is improved.

Description

technical field [0001] The invention relates to the technical field of tea fertilizer, in particular to a microalgae fertilizer suitable for northern tea. Background technique [0002] Tea tree is a plant that loves acid and fears alkali. The pH value of the soil suitable for tea tree growth is below 6.4, especially 4.0-5.5 is the best. The northern tea area is brown loam soil, the soil is highly viscous, and the pH value is generally 6.5 to 7.0. Therefore, newly transplanted tea seedlings or newly planted tea gardens in the northern episode often have difficulties in rooting and low survival, which hinders the development of northern tea. develop. At the same time, a large amount of chemical fertilizers are used in tea gardens, resulting in barren soil and poor water and fertilizer retention capacity in tea gardens, which also affects the yield of tea. Microalgae are an important part of soil microorganisms, and have the characteristics of nitrogen fixation, carbon fixati...

The northern tea area is brown loam soil, the soil is highly viscous, and the pH value is generally 6.5 to 7.0. Therefore, newly transplanted tea seedlings or newly planted tea gardens in the northern episode often have difficulties in rooting and low survival, which hinders the development of northern tea. develop

At the same time, a large amount of chemical fertilizers are used in tea gardens, resulting in barren soil and poor water and fertilizer retention capacity in tea gardens, which also affects the yield of tea.
