specific Embodiment approach 1

[0019] Embodiment 1: In this embodiment, a fertilizer for preventing and treating clubroot of cabbage consists of 8 to 9 parts of organic fertilizer dry basis, 0.8 to 1 part of quicklime and 0.2 to 0.5 parts of sepiolite in parts by weight.

[0020] The advantage of this implementation mode:

[0021] 1. This embodiment can effectively inhibit the generation of cabbage clubroot in the continuous cropping plots of cabbage, which is equivalent to giving the soil anti-cancer drugs;

[0022] Two, use this embodiment to prepare the fertilizer for preventing and treating cabbage clubroot, and the cure rate of cabbage clubroot in the continuous cropping planting area of ​​cabbage can reach more than 98%;

[0023] 3. The disease of cabbage occurs in the roots, which can be damaged at the seedling stage, and the seedlings will die when it is serious; the cabbage clubroot disease bacteria survives in the soil for a long time, and infects cabbage and other cruciferous plants through the s...

specific Embodiment approach 2

[0025] Specific embodiment two: the difference between this embodiment and specific embodiment one is: the dry base of the organic fertilizer is composed of 2 to 3 parts of chicken manure, 3 to 4 parts of cow dung, 1 to 2 parts of pig manure and 1 to 4 parts of straw; the dry base of organic fertilizer is specifically completed according to the following steps:

[0026] 1. Weighing: Weigh 2 to 3 parts of chicken manure, 3 to 4 parts of cow dung, 1 to 2 parts of pig manure and 1 to 4 parts of straw to obtain raw materials by weight;

[0027] 2. Mixing: Mix 2 tons of raw materials weighed in step 1 with 5 kg to 6 kg of probiotic stock solution evenly, then control the water content at 40% to 50%, and then pile it into a pile with a width of 2m to 2.5m and a height of 0.5 The strip-shaped pile of m ~ 0.8m should be covered with straw mats. At 48h ~ 50h, add water to adjust the temperature, control the temperature in the pile to 50°C ~ 55°C, and keep the temperature in the pile at...

specific Embodiment approach 3

[0028] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is: the content of organic carbon in the dry base of the organic fertilizer is 40.6% to 42.0%, and the content of N is 2.6% to 2.7%. The content of P is 0.63%-0.70%, and the content of K is 1.22%-1.35%. Other steps are the same as those in Embodiment 1 or 2.

Abstract

The invention relates to a fertilizer and a preparation method thereof, particularly a fertilizer for preventing and treating clubroot of Chinese cabbage and a preparation method thereof. The invention aims to solve the problem that the Chinese cabbage roots suffer commonly from clubroot in the Chinese cabbage succession cropping region. The fertilizer for preventing and treating clubroot of Chinese cabbage is composed of organic fertilizer dry basis, quicklime and meerschaum. The preparation method comprises the following steps: 1. material weighing; 2. raw material pretreatment; 3. granulation; and 4. drying to obtain the fertilizer for preventing and treating clubroot of Chinese cabbage. The fertilizer can effectively inhibit clubroot of Chinese cabbage in Chinese cabbage succession cropping lots from generation, and is equivalent to anti-cancer drugs which are fed to soil. By using the fertilizer for preventing and treating clubroot of Chinese cabbage, the cure rate of the clubroot of Chinese cabbage in the Chinese cabbage succession cropping region can reach 98% above. The invention can obtain a fertilizer for preventing and treating clubroot of Chinese cabbage.

Description

technical field [0001] The invention relates to a fertilizer and a preparation method thereof. Background technique [0002] The existing method of making special fertilizer for cabbage is to mix urea, potassium sulfate, general calcium, and additives in a weight ratio of 32.6:10.0:35.7:21.7, pulverize each component, mix evenly, dry, cool, and screen to become Pure fertilizer is made by mixing pure fertilizer and effective silicon dioxide at a weight ratio of 100:18; the particle diameter is 14mm. [0003] The prior art mainly studies the method of the basic fertilizer needed for cabbage planting, but the existing method is aimed at purely producing fertilizer, which is a manufacturing method of fertilizer production. The fertilizer produced by the existing method only meets the needs of the normal growth of cabbage. Contents of the invention [0004] The purpose of the present invention is to solve the problem of common cabbage root swelling disease in the cabbage cont...
