Embodiment 1
[0014] Embodiment 1 preparation active ingredient content is the water dispersible granule of 5.5%
[0015] The specific ratio is:
[0016] Raw material dosage (parts by weight)
[0017] Trichoderma harzianum spore powder 0.5
[0018] Chrysanthemum root powder 2.5
[0019] 6% oligosaccharide·catenin 2.5
[0020] Sodium lignosulfonate 7
[0021] Clay and plaster top up to 100
[0022] The preparation method comprises: weighing Trichoderma harzianum spore powder, chrysanthemum chrysanthemum root powder, 6% oligosaccharide-catenin, sodium lignosulfonate, clay and gypsum, mixing them uniformly, and preparing the active ingredient content of 5.5% by jet milling. Wettable powder; after granulation, it can be made into 5.5% water-dispersible granules.
Embodiment 2
[0023] Example 2 Preparation of water-dispersible granules with an active ingredient content of 8%
[0024] The specific ratio is:
[0025] Raw material dosage (parts by weight)
[0026] Trichoderma harzianum spore powder 0.5
[0027] Chrysanthemum root powder 2.5
[0028] 6% oligosaccharide·catenin 5
[0029] Sodium lignosulfonate 7
[0030] Clay and plaster top up to 100
[0031] The preparation method comprises: weighing Trichoderma harzianum spore powder, chrysanthemum chrysanthemum root powder, 6% oligosaccharide-catenin, sodium lignosulfonate, clay and gypsum, mixing them evenly, and preparing the active ingredient content of 8% by jet milling. Wettable powder; after granulation, it can be made into 8% water-dispersible granules.
Embodiment 3
[0032] Example 3 Preparation of granules with an active ingredient content of 13% (disintegration)
[0033] The specific ratio is:
[0034] Raw material dosage (parts by weight)
[0035] Trichoderma harzianum spore powder 0.5
[0036] Chrysanthemum root powder 2.5
[0037] 6% oligosaccharides·catenin 10
[0038] sodium bicarbonate 1
[0039] Clay and plaster top up to 100
[0040] The preparation method comprises: weighing Trichoderma harzianum spore powder, chrysanthemum chrysanthemum root powder, 6% oligosaccharide chain protein, sodium bicarbonate, clay and gypsum, mixing uniformly, adding binder water to the mixture, mixing, granulating and Drying is prepared into granules with an active ingredient content of 13%. Wherein, the added amount of the water is 7% of the total weight of the mixture, and the water is removed after drying, so the weight of the water is not included in the weight of the granules.
