Embodiment 1

[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.

Abstract

The invention discloses a compounded agent of a potassium fertilizer for rice as well as a preparation method and an application thereof. The compounded agent comprises the following components according to a certain ratio: potassium chloride, ibuprofen, Tween-20, and laurocapram. The method comprises the following steps: (1) potassium chloride is weighed, water is added for dissolving, and a solution A is obtained; (2) ibuprofen and laurocapram weighed and mixed uniformly, ethyl alcohol is added for dissolving, dissolving liquid is dropped into warm water with continuously stirring, and a mixed solution B is obtained; (3) at a normal temperature, the mixed solution B obtained in the step (2) is dropped into the solution A, uniform mixing is carried out, and a mixed solution C is obtained; (4) the Tween-20 is weighed and dropped into the mixed solution C, a mixed solution D is obtained, uniform mixing is carried out, volumetric flask preparation is carried out, and the compounded agent of the potassium fertilizer for rice is obtained. The method has the advantages of low cost, easy and simple operation; the compounded agent can substantially promote growth of rice root, inhibit chlorophyll degradation, and delay leaf aging; with the same application amount of the potassium fertilizer, compared with the common potassium fertilizer, the compounded agent of the potassium fertilizer has obvious yield increasing effects, and yield of rice is increased by 9.1-15.9%.

Description

Technical field [0001] The present invention relates to the field of agricultural technology, in particular to a potash fertilizer (potassium chloride), plant growth regulator IBU (ibuprofen), surfactant Tween 20 (Tween 20), penetrant Azone (azone), and more specifically It relates to a rice potash fertilizer compound formulation, and also relates to a preparation method of a rice potash fertilizer compound formulation, and also relates to the use of a rice potash fertilizer compound formulation, which is suitable for the whole growth period of rice. Background technique [0002] Rice is the main food crop in China, with an annual planting area of ​​about 30 million ha 2 , Accounting for 30% of the country’s cereal planting area and 27% of the world’s rice planting area; the total rice output is nearly 200 million tons, accounting for 38% of the country’s total grain output and 35% of the world’s total rice output. With population growth and economic development, China's food dem...
