Embodiment 1

[0043] Embodiment 1: special controlled-release fertilizer for tea tree, total nutrient: nitrogen, phosphorus pentoxide, potassium oxide content are respectively 19%, 11%, 11%, all are percentage by mass. The raw material components are as follows:

[0044] Sulfur coated compound fertilizer 200kg

[0045] 6% thermoplastic resin coated compound fertilizer 240kg

[0046] 4% thermoplastic resin coated urea 100kg

[0047] 6% thermoplastic resin coated urea 80kg

[0048] 8% thermoplastic resin coated urea 55kg

[0049] Potassium sulfate compound fertilizer 200kg

[0050] Diammonium phosphate 70kg

[0051] Magnesium sulfate 50kg

[0052] Zinc sulfate 5kg.

[0053] The preparation method is that the above-mentioned raw materials are put into a blender and stirred for 5-10 minutes, and fully mixed to obtain the product. Then the mixed fertilizer is sent to the metering and packaging machine for metering and packaging.

Abstract

The invention relates to a special controlled-release fertilizer for tea plant and a preparation method. The special controlled-release fertilizer is prepared by the ingredients of sulphur-coated fertilizer, thermoplastic resin-coated fertilizer of 6 percent, thermoplastic resin-coated urea of 4 percent, thermoplastic resin-coated urea of 6 percent, thermoplastic resin-coated urea of 8 percent, potassium sulphate compound fertilizer and diammonium phosphate. The invention can be fertilized in one time before the sprouting of the tea plant without topdressing, and the yield result is better; the utilization of fertilizer can be increased with labor saving.

Description

technical field [0001] The invention relates to a method for producing a special controlled-release fertilizer for crops by using sulfur and a thermoplastic resin coating, in particular to a special controlled-release fertilizer for tea trees and a preparation method thereof, belonging to the technical field of slow / controlled release fertilizers. Background technique [0002] Tea is originally produced in the Yunnan-Guizhou Plateau. my country is the first country in the world to discover tea trees and utilize tea. As of 2003, the world's harvested tea garden area was 2.41 million hectares, and the tea output was 3.2 million tons. In the past 20 years, the area of ​​my country's tea gardens and tea output have grown steadily, with a total area of ​​1.1 million hectares, ranking first in the world; the annual output of tea is 700,000 tons, accounting for 23% of the world's total, ranking second in the world. Tea has also become one of my country's important export agricultu...
