[0050] A rice potash fertilizer compound, which is made of the following raw materials by weight:
[0051]
[0052] A method for preparing a rice potash fertilizer compound, the steps of which are:
[0053] (1) Weigh out potassium chloride at room temperature (4 or 7 or 10 or 14 or 18 or 22 or 25 or 28°C), add 50 or 75 or 100 ml of water to dissolve to obtain solution A.
[0054] (2) Weigh out ibuprofen and azone in proportion at room temperature (4 or 8 or 12 or 17 or 21 or 24 or 26 or 28℃), mix them, and add 0.3 to the mixture of ibuprofen and azone Or 0.4 or 0.5ml ethanol is fully dissolved, then slowly drip the dissolved solution into 100 or 150 or 200ml warm water, the water temperature is controlled at 60 or 70 or 80 or 90 ℃, and keep stirring until no particles are precipitated to obtain mixed solution B;
[0055] (3) At normal temperature (4 or 8 or 12 or 17 or 21 or 24 or 26 or 28°C), drop the mixed solution B obtained in step (2) into the solution A obtained in step (1), and...
Embodiment 12
[0064] The application of a rice potash fertilizer compound in rice production includes the following steps:
[0065] A. Pick the full and consistent rice seeds, soak the seeds in an incubator at 30°C for 24 hours, and then accelerate the germination for 30 hours. Select rice seedlings with the same germination (root length≈seed length, bud length≈1 / 2 seed length), and wrap them with sponge , Put it into the round hole (pore size ≈ 3cm) of the foam board, and then float the foam board with seedlings in different treatment solutions, place the light intensity 10000Lx, light (29℃, 12h) and dark (26℃, 12h) ) Cultivation in alternate incubators, processing for 30 days to take photos and statistics.
