Description
Technical Field
The invention belongs to the technical field of agriculture, and particularly relates to a foliar fertilizer for promoting early germination of tea trees and application thereof.
Background
Tea is one of the longest beverages in the history of China, and is called three-major nonalcoholic beverage with coffee and cocoa. Spring tea is the most dominant form of consumption in the domestic tea market, especially in the green tea market. The young shoots of the tea trees germinate in advance, which is beneficial to increasing the number of famous tea and achieving the effects of increasing yield and quality. Meanwhile, the tea tree can effectively promote the competitive power of tea leaves in the market in the early stage of germination, so that the economic benefit of tea farmers is increased.
The spring tea fertilizer is a material basis for forming and germinating and growing young shoots in spring, and the foliar fertilizer can effectively avoid the influence of leaching, fixing, combining and the like of nutrients in soil, and is a cultivation measure for improving crop nutrition, preventing and treating nutrient deficiency and regulating and controlling growth and development in agricultural production. Therefore, when the soil fertilization can not meet the requirements of high yield and high quality of crops in time, the growth and development of the crops are regulated and controlled by spraying nutrient elements or physiologically active substances on leaf surfaces, and the absorption and utilization efficiency of the crops on the nutrients is promoted, so that the purposes of improving the yield of the crops and improving the quality of the crops are achieved.
Brassinolide is a class of sterols that is ubiquitous in plants and is currently classified by many plant physiology as the sixth largest class of hormone in plants. Brassinolide plays an important role in the growth and development process of plants, such as promoting growth, increasing stress resistance of plants, delaying senescence, promoting cell re-differentiation and the like. Potassium is a mineral element essential for crops, it exists in the interstitial fluid of various organs of plants in an ionic state, and its main function is related to metabolism of plants. It is known that more than 60 enzymes require potassium as an activator. The effect of potassium ions on promoting germination of crops and vegetable seeds has been studied.
The invention firstly provides that 24-epibrassinolide, monopotassium phosphate and dipotassium phosphate with proper concentrations are prepared into the tea leaf fertilizer, so that the dormancy of winter buds of tea trees is relieved in advance, the photosynthesis of the tea trees is improved, and further the germination of the tea trees is promoted. Up to now, no report or invention has been made in the world that the ingredient can promote the early germination of tea trees, and even similar reports have not been made.
