Problems solved by technology

First, they only provide nutrients and do not condition the soil
Secondly, the nutrient distribution and release rules of these fertilizers are poorly related to the soil nutrient status of orchards in the Jiaodong Peninsula area and the absorption of fruit trees.

preparation example Construction

[0035] The preparation method of the special controlled-release fertilizer for soil conditioning type fruit trees of the present invention, the steps are as follows:

[0036] (1) Preparation of soil conditioning composition

[0037] Potassium humate, calcium humate, and calcium-magnesium phosphate fertilizer are evenly mixed, and granulated according to the prior art to obtain the product. The particle size is 2 to 4 mm.

[0038] (2) Soil conditioning composition, 5% humic acid coated urea, 5% recycled thermoplastic resin coated urea, 5% modified epoxy resin coated potassium nitrate, 4% urea primer Epoxy resin-coated diammonium phosphate, 5% humic acid-coated potassium nitrate, and diammonium phosphate are put into a blender according to the ratio and stirred for 5 to 8 minutes, and fully mixed to obtain the product.

[0039] Then the mixed fertilizer is measured and packaged.

[0040] In the application of the soil conditioning type special controlled-release fertilizer fo...

Abstract

The present invention relates to Jiaodong peninsula soil regulation type fruit tree special controlled release fertilizer, a preparation method and an application thereof. The fruit tree special controlled release fertilizer comprises a soil regulation composition, 5% humic acid coated urea, 5% humic acid coated potassium nitrate, urea undercoated 5% modified epoxy resin coated potassium nitrate, urea undercoated 4% modified epoxy resin coated diammonium phosphate, 5% recycled thermoplastic resin coated urea and diammonium phosphate. The fruit tree special controlled release fertilizer is prepared by uniformly mixing various raw materials. The fruit tree special controlled release fertilizer is applied as basal fertilizer in one time, and does not require dressing. According to the present invention, with the nutrient condition and the acidification characteristics of the Jiaodong peninsula soil, the accurate compounding is performed to form the special controlled release fertilizer, wherein the special controlled release fertilizer provides a regulation effect for the soil, the nutrient ratio and the nutrient releasing basically meet the nutrient absorption regularity of the main fruit trees in Jiaodong peninsula; the fertilizer utilization efficiency is significantly improved; the yield is increased; the physiological diseases due to nutrient deficiency are reduced.

Description

technical field [0001] The invention relates to a controlled-release fertilizer, in particular to a special controlled-release fertilizer for soil conditioning fruit trees suitable for Jiaodong Peninsula and its preparation and application, belonging to the technical field of production and application of controlled-release fertilizers. Background technique [0002] Shandong Province is one of the important fruit producing areas in the north of my country. The cultivated area and output of apples rank the second and the first among all provinces in the country respectively. The Jiaodong Peninsula is the main fruit producing area in Shandong Province. Yantai apples, Laiyang pears and other famous specialty products are well-known throughout the country, and Yantai big cherries, which have developed rapidly in recent years, are even high-end fruits in my country. [0003] The soil in Jiaodong Peninsula is dominated by brown soil, moist brown soil and some cinnamon soils. The pH...
