Special high-concentration garlic long-acting slow-release fertilizer and preparation method thereof

Abstract

The invention discloses a special high-concentration garlic long-acting slow-release fertilizer which comprises the following raw materials in parts by weight: 200-300 parts of urea, 200-280 parts of monoammonium phosphate, 200-300 parts of potassium sulfate, 150-240 parts of a calcium magnesium phosphate fertilizer, 20-70 parts of activated humic acid, 1-20 parts of zinc sulfate, 1-20 parts of borate, 1-20 parts of a urease inhibitor, 1-20 parts of a nitration inhibitor and 20-40 parts of a concrete fertilizer. Due to addition of the activated humic acid and calcium magnesium phosphate fertilizer, the special high-concentration garlic long-acting slow-release fertilizer disclosed by the invention is capable of increasing content of organic matters in soil, promoting absorption of nutrients by garlic plants and reducing the problem of 'bread garlic' caused by continuous cropping nutritional deficiency and poor soil environments in main garlic production regions, and has great significances for promoting positive cultivation circulation of soil in the main garlic production regions and stable garlic supply.

Description

technical field [0001] The invention belongs to the technical field of special fertilizer formulations for crops, and in particular relates to a long-acting slow-release fertilizer special for high-concentration garlic and a preparation method thereof. Background technique [0002] Garlic is an annual plant of the Liliaceae family, whose main edible parts are bulbs and flower stems. In my country, garlic is mainly grown in Zhongmu and Qixian County in Henan, Jinxiang and Lanling in Shandong, Pizhou in Jiangsu and other places, and winter garlic is the main one. Garlic is a crop with high economic added value. Generally, it is planted around October in the Gregorian calendar and harvested in May of the next year. The growth period lasts for 7 months. During its growth period, it is generally necessary to fertilize according to the soil fertility and the growth of garlic, including base fertilizer and top dressing. Most of the nutrients needed for the growth of garlic seedli...

AI Technical Summary

Problems solved by technology

[0004] (1) The fertilizer effect time is short, which cannot meet the nutrient requirements of garlic throughout the growth period;

[0005] (2) The ratio is unscientific, resulting in low fertilizer utilization efficiency;

[0006] (3) Nutrients are single, resulting in the lack of trace elements in crops and soil;

[0007] (4) Long-term use is likely to cause soil compaction;

[0008] In order to solve the above problems caused by the application of most special compound (mixed) fertilizers for garlic, a special long-acting slow-release fertilizer for garlic is now introduced. The raw materials of traditional slow-release fertilizer nitrogen fertilizers are mainly coated and coated. The addition of trace element raw materials in products produced by membrane is limited, which is not conducive to the supplement of medium and trace elements, and traditional craft products will generate waste water and waste gas during the production process, which has a great adverse impact on the environment
