Abstract

The invention discloses a sustained/controlled-release fertilizer for tea trees. The sustained/controlled-release fertilizer is characterized by containing the following substances in parts by weight: 30-45 parts of chicken manure, 15-20 parts of ammonium nitrate, 9-12 parts of potassium sulfate, 0.1-0.2 part of lactobacillus powder, 0.1-0.2 part of nitrobacterium powder, 0.1-0.2 parts of rhizobium powder, 3-6 parts of zinc sulfate, 10-15 parts of diammonium phosphate, 5-9 parts of calcium dihydrogen phosphate, 15-20 parts of pigweed cakes, 15-20 parts of rice bran, 10-20 parts of red pine wood sawdust, 10-14 parts of black walnut wood sawdust, 11-20 parts of lemon wood sawdust, 5-8 parts of oilseed straw powder and 14-19 parts of veronica linariifolia straw powder. The sustained/controlled-release fertilizer has the beneficial effects that the fertilizer gives priority to organic fertilizers, and a great deal of microelements are added, so that the growth needs of tea are supplemented, the quality of the tea is improved, and the soil is also improved greatly; moreover, the sustained/controlled-release fertilizer is high in activity and high in utilization ratio, is free from secondary pollution and is environmental-friendly.

Description

The slow control of a kind of tea tree fertilizer

Technical field

The present invention relates to the slow control of a kind of tea tree fertilizer.

Background technology

Current tea tree planting fertilizer type used is a lot, and wherein tealeaves special fertilizer adopts the nitrogen-phosphorus-potassium compound fertilizer that can buy on market mostly, and mainly by N, P, K tri-, large inorganic elements forms for it, can meet at short notice the growth needs of tea tree.But life-time service can make soil aggregate be destroyed, easily cause soil compaction, soil property hardening, thereby affect growth of tea plant, tea leaf quality declines.Though simple fertilizer is rich in organic matter simultaneously, nutrient discharges slowly, and tea tree absorbs slowly, fertilizer efficiency is low, between various available nutrient, do not reach active balance, due to tealeaves fertilizer formula science not, cause tea yield not high, in tealeaves, chemical composition and micronutrient levels are not high.

Slow release fertilizer claims again slow-release fertilizer or release and release control fertilizer, and compound release rate in the soil control slow or that nutrient releasing speed can obtain to a certain extent that contains nutrient in its fertilizer continues to absorb for crop.Use slow release fertilizer can reduce the particularly loss of nitrogen in soil of fertilizer nutrient, improve utilization rate of fertilizer, reduce fertilising operation number of times, save labour and expense, and can alleviate the pollution that excessive fertilization causes for environment.Current slow release fertilizer both domestic and external is all generally by coating, to wrap up the physical methods such as packing coating to reach the object that extends fertilizer efficiency, as the coated fertilizer coated fertilizer of bag Thio Urea polymer coated fertilizer fertilizer bag fertilizer and by Quick-dissolving fertilizer and the mixing formed Wrapped fertilizer of rubber latex etc.Also have and adopt slow controlled-release technology that physics and biochemical method combine to produce slow release fertilizer.The general cost of these fertilizer is higher, and seldom possesses hole and adsorptive power, more without increasing soil fertility, improves the features such as Soil structure.

Summary of the invention

Technical problem to be solved by this invention is to provide the slow control of a kind of tea tree fertilizer.

For solving the problems of the technologies described above, the technical solution used in the present invention is:

The slow control of a kind of tea tree fertilizer, it is characterized in that, the material that comprises following parts by weight: chicken manure 30-45 part, ammonium nitrate 15-20 part, potassium sulfate 9-12 part, milk-acid bacteria powder 0.1-0.2 part, nitrobacteria powder 0.1-0.2 part, root nodule bacterium powder 0.1-0.2 part, zinc sulfate 3-6 part, Secondary ammonium phosphate 10-15 part, monocalcium phosphate 5-9 part, Lay cake 15-20 part, rice bran 15-20 part, Korean pine wood chip 10-20 part, black walnut wood chip 10-14 part, lemon wood chip 11-20 part, oilseeds stalk powder 5-8 part, turnip stalk powder 14-19 part.

The invention has the beneficial effects as follows: it is main adopting fertilizer, but has increased Macro and microelements, supplementing tea growth needs, and improves tea leaf quality, has also improved widely soil, and active high, and utilization ratio is high, non-secondary pollution, environmental protection.
