Compound fertilizer for improving tea yield and preparation method thereof

Abstract

The invention discloses a compound fertilizer for improving a tea yield and a preparation method thereof. According to a field trial with four-factor five-level quadratic regression universal rotational-combination design, a regression effect model of an organic fertilizer, nitrogenous, phosphorous and potassic fertilizers and the tea yield is established, so as to analyze factors and interaction. The compound fertilizer is prepared from the components at a certain ratio: 799.40-928.10kg / 677m<2> of the organic fertilizer, 15.30-16.92kg / 667m<2> of the pure nitrogenous fertilizer, 15.00-17.14kg / 667m<2> of the pure phosphorous fertilizer, 11.38-13.58kg / 667m<2> of the pure potassic fertilizer. With the adoption of the compound fertilizer provided by the invention, the tea yield can be improved. The compound fertilizer can be applied to fertilization of tea trees of a tea garden.

Description

technical field [0001] The invention belongs to the field of plant cultivation, and in particular relates to the fertilization technology of tea trees. Background technique [0002] Tea is one of the three major non-alcoholic beverages in the world and an important economic crop in China. With the improvement of people's living standards, the problems of tea yield and quality have gradually been paid attention to. Nitrogen, phosphorus, and potassium are the three major nutritional elements necessary for the growth and development of tea trees, which have an important impact on the yield and quality of tea. Reasonable application of N, P, and K fertilizers is the key to high-quality and high-yield tea. In the management of tea gardens, due to partial application of nitrogen fertilizers, no or less application of organic fertilizers, etc., soil fertility degradation and environmental pollution are caused, which indirectly affects the yield and quality of tea. A large number ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, there are many reports on the influence of organic fertilizers, nitrogen, phosphorus, and potassium fertilizers on the growth and development of tea leaves, but most of them are studying the influence of a single factor or two factors in these 4 factors on tea leaves, and there is no report yet. Can fully analyze and use the relationship model between these 4 factors and tea yield, the formula of fertilizer needs to be improved, so as to further increase the tea yield
