Embodiment 1

[0012]A preparation method of rice flavor-enhancing zinc fertilizer, the steps are as follows:

[0013](1) Dissolve 50g of humic acid in 150ml of 0.1mol / L NaOH solution, add 40g of zinc citrate while stirring, and then treat the mixed solution with an ultrasonic cell pulverizer at 25kHz for 1 hour. It is carried out in a high-purity oxygen atmosphere with an oxygen flow rate of 25ml / min. After the reaction is completed, it is filtered and dried to obtain chelated zinc.

[0014](2) After mixing 45 g of chelated zinc, 30 g of ammonium sulfate, 20 g of potassium dihydrogen phosphate, 3 g of brassinolide, and 2 g of indole acetic acid, slowly add 1L of distilled water with a mass of 1L, stir well, and adjust the pH of the solution to 6.8 Obtain flavor-enhancing zinc fertilizer.

[0015]Using the rice variety Yangnongxiang 28 as the test material, each straw substrate tray was evenly sown with 80g rice seeds that had been soaked, sterilized and germinated, darkened for 48 hours, and placed in the...

Embodiment 2

[0019]A preparation process and application method of a flavor-enhancing fertilizer suitable for rice seedling raising substrate, the steps are as follows:

[0020](1) Dissolve 100g of humic acid in 200ml of 0.1mol / L NaOH solution, add 80g of zinc citrate while stirring, and then treat the mixed solution with an ultrasonic cell pulverizer at 25kHz for 1 hour. It is carried out in a high-purity oxygen atmosphere with an oxygen flow rate of 20 ml / min. After the reaction is completed, the chelated zinc is obtained after filtration and drying.

[0021](2) After mixing 45 g of chelated zinc, 30 g of ammonium sulfate, 20 g of potassium dihydrogen phosphate, 3 g of brassinolide, and 2 g of indole acetic acid, slowly add 1L of distilled water with a mass of 1L, stir well, and adjust the pH of the solution to 7.2 Obtain flavor-enhancing zinc fertilizer.

[0022]Using the rice variety Yangnongxiang 28 as the test material, each straw substrate tray was evenly sown with 90g rice seeds that had been soa...

Abstract

The invention relates to a preparation method of an aroma-enhancing zinc fertilizer suitable for a rice straw matrix, which belongs to the technical field of agricultural fertilizers, is simple and convenient, can provide medium and trace element nutrients for rice straw matrix seedlings, provides an excellent root micro-ecological environment for the seedlings by matching with the straw matrix, promotes the absorption of nutrient elements by root systems, and improves the yield of the seedlings. The synthesis and accumulation of aroma substances in rice bodies are improved, the growth of riceseedlings can be promoted, the content and stress resistance of trace elements in rice can be further improved, and the content of aroma substances in rice grains can also be improved. The rice strawseedling raising substrate can be applied to rice straw seedling raising substrates and can also be widely applied to substrates of facility crops, horticulture, flowers and plants and the like, theuse method is simple, the fertilizer absorption level and the fertilizer utilization rate of the crops can be improved, the stress of agrochemical input to the environment is reduced, the yield of agricultural products is increased, the quality is improved, and good application prospects are achieved.

Description

Technical field[0001]The invention belongs to the technical field of agricultural fertilizers, and relates to a method for preparing a rice flavor-enhancing zinc fertilizer, and specifically to a method for preparing a flavor-enhancing zinc fertilizer suitable for a rice straw substrate.Background technique[0002]Fragrant rice is rice with a unique aroma and good quality. In today's market, high-priced, high-quality rice brands are based on ordinary rice mixed with fragrant rice. On a global scale, the selling price of fragrant rice is usually twice as high as that of conventional high-quality rice. Although the global consumption and demand of fragrant rice continue to be at a high level and are still growing year by year, the fragrant rice of various rice-producing countries still cannot meet people's demand for fragrant rice. How to increase the aroma content of conventional high-quality rice on the basis of ensuring rice yield is a research topic of great significance to my count...
