Embodiment 1

[0111] A comparative test of a special water-soluble set fertilizer for reducing pomelo juice cell granulation of the present invention was carried out in a high-yield pomelo garden.

[0112] 1. Materials and methods

[0113] (1) Overview of the test site

[0114] The test was carried out in Qianshan Village, Nansheng Town, Pinghe County, Zhangzhou City (N 24°44′66.41′′, E 117°49′46.59′′), at the Guanxi honey pomelo base at an altitude of 66 meters, which belongs to the south subtropical monsoon area. The annual average precipitation is 1724mm, and the three-year average temperature is 21.3°C. The test site is brick red soil, and the red heart pomelo variety is selected for the test supply, and the plant height is basically the same. The physical and chemical properties of the tested soil are 158.6 mg / kg of alkaline nitrogen, 77.6 mg / kg of available phosphorus, 132.1 mg / kg of available potassium, 24.3 g / kg of organic matter, and pH5.13.

Embodiment 2

[0151] A comparison test of the water-soluble set fertilizer specially used for reducing pomelo juice cell granulation of the present invention in the production of honey pomelo.

[0152] 1. Materials and methods

[0153] (1) Overview of the test site

[0154] The test was carried out in Huangzhuang Village, Xiazhai Town, Pinghe County, Zhangzhou City (N 24°21′32.18′′, E 117°08′19.12′′), at the Guanxi honey pomelo base at an altitude of 412 meters, which belongs to the south subtropical monsoon area. The annual average precipitation is 1724mm, and the three-year average temperature is 21.3°C. The test site is brick red soil, and the red heart pomelo variety is selected for the test supply, and the plant height is basically the same. The soil granulation properties of the test supply were 157.4 mg / kg alkaline nitrogen, 106.3 mg / kg available phosphorus, 131.9 mg / kg available potassium, 24.2 g / kg organic matter, and pH5.11.

Abstract

The invention discloses a special water-soluble set fertilizer for reducing pomelo juice cell granulation and its application method. The mass ratio of phosphorus and potassium is 7.5-9.5:4-4.5:4-4.5; in the young fruit fertilizer, the mass ratio of nitrogen, phosphorus, and potassium is 4.5-5.5:2-3:3.5-4; In fertilizer, the mass ratio of nitrogen, phosphorus and potassium is 5.5-7:5.5-7:7.5-9.5; in fruit picking and maintenance fertilizer, the mass ratio of nitrogen, phosphorus and potassium is 13.5-16.5:8-10:13.5- 16.5. The set fertilizer of the invention can meet the growth requirement of honey pomelo, promote it to alleviate the granulation phenomenon of juice cells, the honey pomelo granulation index is 0.192, and simultaneously achieve high yield and high profit.

Description

technical field [0001] The invention belongs to the technical field of fertilizer preparation, and in particular relates to a special water-soluble set fertilizer for reducing pomelo juice cell granulation and an application method thereof. Background technique [0002] Honey pomelo is a rising star in my country's citrus production family, accounting for 85% of the world's total output. Its fruit is large, with few cores and rich in nutrition. It is a subtropical fruit with high economic value. In recent years, the granulation of honey pomelo juice has become more and more serious, seriously affecting fruit quality and reducing commodity value, which has affected the development of its industry. [0003] Honey pomelo is a high-yield crop that needs more fertilizer. During the growth and development process, it needs to absorb a lot of nutrients, among which nitrogen, phosphorus, and potassium are the most required, followed by calcium, magnesium, boron, zinc and other eleme...
