[0002] Rice is an important food crop and cash crop. Effectively utilizing limited land resources and improving the yield and quality of rice crops are the direction and eternal subject of people's efforts. Among them, rice sheath blight is a fungal disease caused by infection of Rhizoctonia solani. It is one of the most common diseases of rice. Generally, early rice is more serious than late rice, often resulting in incomplete grains and increased empty shell rate. In severe cases, it can cause the plant to fall and die.

[0163] Comparative Example 13.

[0164] The difference from Example 3 is that no boron nitride powder or urea is added to the regulating solution.

[0165] The products of Examples 1 to 3 and Comparative Examples 1 to 13 were subjected to performance tests, and the test results are as follows:

[0166]

[0167]

[0168] It can be seen from Comparative Examples 1 to 13 and Examples 1 to 3 that;

[0169] The product of Example 3 has excellent resistance to rice sheath blight infection rate and excellent rice yield increase performance, and at the same time, the nitrogen absorption and utilization rate and the zinc content of rice are significantly improved;

[0170] The product did not contain any of the property-adjusting and strengthening linking agent or wollastonite hybrid modifier, and the product's performance showed a significant trend of deterioration. The combination of the two agents can achieve synergistic effects, and the coordinated balance of the product's yield increase, disease resistance and rice quality can be improved.

[0171] The properties of the products tend to deteriorate when the continuous adjustment halloysite nanotube agent is not used for treatment in the preparation of the property-adjusting strong linking agent, the continuous adjustment liquid is not used for treatment in the preparation of the continuous adjustment halloysite nanotube agent, the irradiated halloysite nanotube is not used for treatment in the continuous adjustment halloysite nanotube agent, the silane coupling agent KH560 and hydroxyapatite are not added to the continuous adjustment liquid, and the strong modifying liquid is not used for treatment in the preparation of the property-adjusting strong linking agent. The continuous adjustment liquid obtained by the method of the present invention is combined with the strong modifying liquid treatment of the present invention, and the specific continuous adjustment halloysite nanotube agent treatment of the present invention. At the same time, the fact that the strong modifying liquid treatment is not used in the preparation of the property-adjusting strong linking agent has the greatest influence on the preparation of the property-adjusting strong linking agent.

[0172] The performance of the products tends to deteriorate when the wollastonite hybrid modifier is not treated with a zinc agent adjusted by nano-silica, the zinc agent adjusted by nano-silica is not treated with a re-adjusting liquid, the zinc agent adjusted by nano-silica is not treated with a heat-insulating nano-silica, the wollastonite hybrid modifier is not treated with a regulating liquid, the wollastonite impregnating agent is not added to the regulating liquid, and boron nitride powder and urea are not added to the regulating liquid. The performance effect of the product adjusted by nano-silica obtained by the specific regulating liquid treatment and the re-adjusting liquid treatment combined with the heat-insulating nano-silica treatment of the present invention is the most significant. The wollastonite hybrid modification prepared by using other methods and agents instead is not as obvious as the effect of the present invention.

[0173] Fertilizer was applied at a rate of 100 kg per mu to test the performance of rice. Saline-alkali and cadmium soil with a salt content of 0.60% and a cadmium content of 0.8% was selected to test the cadmium content in rice.

[0174] Cadmium content in rice (mg / Kg) Example 1 0.04 Example 2 0.03 Example 3 0.03 Comparative Example 1 0.25 Comparative Example 2 0.20 Comparative Example 3 0.15 Comparative Example 4 0.17 Comparative Example 5 0.11 Comparative Example 6 0.21 Comparative Example 7 0.28 Comparative Example 8 0.22 Comparative Example 9 0.18 Comparative Example 10 0.15 Comparative Example 11 0.24 Comparative Example 12 0.20 Comparative Example 13 0.17

[0175] It can be seen from Examples 1-3 and Comparative Examples 1-13 that Product Example 3 has an excellent effect on inhibiting cadmium absorption by rice, and the cadmium content in rice is the lowest. At the same time, no wollastonite hybrid modifier and no property-adjusting and strengthening linking agent are added. The cadmium inhibition effect of Product Example 3 on rice has a significant trend of deterioration, and the performance change of the product without adding the wollastonite hybrid modifier is higher than that of the product without adding the property-adjusting and strengthening linking agent. The wollastonite hybrid modifier has an excellent effect on inhibiting cadmium absorption by rice.

[0176] The present invention further explores the product performance through the preparation of a strong modified liquid;

[0177] The strong modifying liquid comprises the following raw materials in parts by weight:

[0178] 4.5 parts of nano-mica powder, 5.5 parts of 6% sodium alginate solution by mass, 2 parts of nano-calcium carbonate, 3.5 parts of 5% dopamine hydrochloride solution by mass and 1.5 parts of nano-silica sol.

[0179] Experimental example 1.

[0180] The same as Example 3 except that no nano mica powder is added to the strong modifying liquid.

[0181] Experimental example 2.

[0182] The same as Example 3 except that no dopamine hydrochloride solution is added to the strong modifying liquid.

[0183] Experimental Example 3.

[0184] The same as Example 3 except that no nano calcium carbonate is added to the strong modifying liquid.

[0185] Experimental Example 4.

[0186] The same as Example 3 except that no nano silica sol is added to the strong modifying liquid.

[0187] Experimental Example 5.

[0188] The same as Example 3 except that no sodium alginate solution is added to the enhanced modified liquid.

[0189] The performance test results of Experimental Examples 1 to 5 are as follows:

[0190]

[0191]

[0192] It can be seen from Experimental Examples 1 to 5 that the performance of the product deteriorates most significantly in the strong modifying liquid without adding nano mica powder, followed by the absence of nano calcium carbonate. At the same time, the performance of the product tends to deteriorate when no dopamine hydrochloride solution, nano silica sol, or sodium alginate solution is added to the strong modifying liquid. Only when the raw materials such as nano mica powder in the formula of the present invention are coordinated and matched, the performance effect of the product is the most significant. When other methods are used instead, the performance effect is not as significant as that of the present invention.
