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.
