Problems solved by technology

The root system of jujube tree, especially the horizontal root system, stretches far and is small in number. After cutting off, the loss of roots is large, and new roots are not easy to appear in the wound. Therefore, repeated fertilization will damage the root system and affect the growth of the tree and the absorption of nutrients.
There is no report on the special controlled-release fertilizer for jujube tree and its preparation method at present

Embodiment 1

[0043] Embodiment 1: special controlled-release fertilizer for jujube trees, total nutrients: nitrogen, phosphorus pentoxide, and potassium oxide are respectively 21%, 12%, and 17%, all of which are percentages by mass. The raw material components are as follows:

[0044] 5% thermoplastic resin coated potassium nitrate 300kg

[0045] 5% thermoplastic resin coated ammonium phosphate 135kg

[0046] 4% epoxy resin coated compound fertilizer 125kg

[0047] 4% thermoplastic resin coated urea 185kg

[0048] Diammonium phosphate 110kg

[0049] Potassium sulfate 65kg

[0050] Urea 70kg

[0051] Zinc sulfate 5kg

[0052] Borax 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.

Embodiment 2

[0054] Embodiment 2: Special controlled-release fertilizer for jujube trees, total nutrients: nitrogen, phosphorus pentoxide, and potassium oxide are 18%, 12%, and 21% respectively, all in mass percent. The raw material components are as follows:

[0055] 5% thermoplastic resin coated potassium nitrate 350kg

[0056] 5% thermoplastic resin coated ammonium phosphate 135kg

[0057] 4% epoxy resin coated compound fertilizer 125kg

[0058] 4% thermoplastic resin coated urea 130kg

[0059] Diammonium phosphate 110kg

[0060] Potassium sulfate 100kg

[0061] Urea 40kg

[0062] Zinc sulfate 5kg

[0063] Borax 5kg.

Abstract

The invention relates to a special controlled-release fertilizer used for jujube trees and a manufacturing method thereof. The special fertilizer is made by compounding 5 per cent thermoplastic resin-coated potassium nitrate, 5 per cent thermoplastic resin-coated ammonium phosphate, 4 per cent epoxy resin-coated compound fertilizer, 4 per cent thermoplastic resin-coated urea, diammonium phosphate, etc. The special controlled-release fertilizer used for jujube trees of the invention is manured once before the germination of jujube trees and the dressing is avoided. the invention has a good effect on increasing yield and can improve the utilization ratio of the fertilizer and save labor.

Description

technical field [0001] The invention relates to a special controlled-release fertilizer for resin-coated jujube trees and a preparation method thereof, belonging to the technical field of slow / controlled release fertilizers. Background technique [0002] Jujube is rich in nutrition and has been a delicious and nourishing food that people have loved since ancient times. Jujube trees have a long history of cultivation in my country. At present, the national cultivation area is about 330,000 hectares, with an annual output of 350,000 to 600,000 tons of fresh dates. Many countries in the world have the experience of introducing jujube trees from my country, but due to climate, living habits and other reasons, there has been no substantial development. At present, except for a certain area in South Korea, there is no large-scale commercial cultivation in other countries. Therefore, in the international market, the price of fresh dates is very expensive, and 1 ton of fresh dates...
