Special liquid organic fertilizer for tea tree and preparation method thereof

Abstract

The invention discloses a special liquid organic fertilizer for a tea tree and a preparation method thereof. The proportion of each trace element is strictly controlled by combining organic fertilizers and inorganic fertilizers according to the nutrition required in the tea growth process, and the antagonism is suppressed so that the synergistic effect among the elements is effectively realized and the plant can effectively absorb the elements; and by adding the two trace elements of iron and zinc, the functions of enhancing the photosynthesis of the tea tree and avoiding mosaic disease are realized. The special liquid organic fertilizer for the tea tree disclosed by the invention comprises an organic fertilizer extract liquid, potassium sulfate, potassium dihydrogen phosphate, urea, calcium superphosphate, magnesium sulfate heptahydrate, iron chelate, zinc sulfate heptahydrate and the like. The organic fertilizer extract liquid is composed of amino acid, trace elements and beneficial bacteria and comprises the following nutrient elements in percentage by weight: 21.0-24.0% of nitrogen, 7.0-8.0% of phosphorus, 7.0-8.0% of potassium, 0.6-1.2% of calcium, 0.7-1.4% of magnesium, 1.8-2.8% of sulfur, 0.1-0.2% of iron and 0.1-0.5% of zinc.

Description

technical field [0001] The invention relates to an organic fertilizer and a preparation method thereof, in particular to a special liquid organic fertilizer for tea trees. Background technique [0002] Organic fertilizer is mainly derived from plants and (or) animals, and is applied to the soil to provide plant nutrition as a carbon-containing material whose main function is. It is processed from biomass, animal and plant waste, and plant residues to eliminate toxic and harmful substances, and is rich in a large number of beneficial substances, including: a variety of organic acids, peptides, and rich nutrients including nitrogen, phosphorus, and potassium. nutritional elements. It can not only provide comprehensive nutrition for crops, but also has long fertilizer effect, can increase and renew soil organic matter, promote microbial reproduction, improve soil physical and chemical properties and biological activity, and is the main nutrient for green food production.

Problems solved by technology

The fertilization and fertilization of tea planting and production are generally similar, but due to the different formulas of fertilizers applied in the process of tea planting and growth, there are obvious differences in improving the yield of tea, especially in improving the quality of tea, and the difference in tea quality has different effects on human health. health effects
