Problems solved by technology

[0003] In the production of rice, due to some unreasonable factors in the use of fertilizers, the application of nitrogen fertilizers is emphasized in the process of rice planting, and the application of organic fertilizers and micro-fertilizers is ignored. The ratio of organic fertilizers to inorganic fertilizers is seriously unbalanced, and fertilization is unreasonable and improper. As a result, the fertilizer utilization rate is low, leading to nutritional imbalance of rice crops, lodging, yield reduction, and quality decline. At the same time, the soil properties of cultivated land deteriorate and seriously pollute the environment.
The potential of rice production and the efficiency of natural resources such as soil cannot be

Embodiment 1

[0038] The planting method of selenium-enriched rice of the present invention comprises the following steps:

[0039] A, seed soaking treatment: select mature and plump seeds, soak for 1 day with sodium selenate solution and lime water, the concentration of sodium selenate is 0.05mg / L, change the water once a day until the seeds are white;

[0040] B. Configure fine and soft slurry. The slurry is made of the following raw materials: 150kg of animal manure, 8kg of nitrogen, phosphorus and potassium compound fertilizer, 1kg of sodium selenate, 1kg of sodium selenite, and 500kg of fine mud. When configuring, mix the ingredients evenly. Pave into a 3cm thick slurry layer in the field; in the NPK compound fertilizer, the ratio of nitrogen fertilizer, phosphorus fertilizer and potash fertilizer is 3:1:2;

[0041] C. Then sow the seeds on the slurry layer, gently press the seeds into the slurry, so that the surface of the seeds is just covered with a thin layer of slurry; cover the s...

[0053] B. Equipped with fine and soft slurry, which is made of the following raw materials: 160kg of animal manure, 10kg of nitrogen, phosphorus and potassium compound fertilizer, 1kg of sodium selenate, 2kg of potassium selenate, and 600kg of fine mud. When configuring, mix the ingredients evenly. Pave into a 5cm thick slurry layer in the field; in the NPK compound fertilizer, the ratio of nitrogen fertilizer, phosphorus fertilizer and potassium fertilizer is 4:2:3;

[0054] C. Then sow the seeds on the slurry layer, gently press the seeds into the slurry, so that the surface of the seeds is just covered with a thin layer of slurry;...

Embodiment 3

[0064] The planting method of selenium-enriched rice of the present invention comprises the following steps:

[0065] A. Seed soaking treatment: select mature and plump seeds, soak them in sodium selenite solution and lime water for 3 days, the concentration of sodium selenite is 1 mg / L, change the water once a day until the seeds are white;

[0066] B, configure the soft slurry, the slurry is made of the following raw materials by weight: animal manure 170kg, NPK compound fertilizer 12kg, sodium selenate 1kg, potassium selenate 1kg, sodium selenite 1kg, potassium selenite 1kg, 700kg of fine mud, mix each component evenly when preparing, and spread it into a 6cm thick slurry layer in the field; the ratio of nitrogen fertilizer, phosphorus fertilizer and potassium fertilizer in the nitrogen, phosphorus and potassium compound fertilizer is 5:3:4;

[0067] C, then sow the seeds on the slurry layer, gently stroke the seeds and press them into the slurry, so that the surface of the...

Abstract

The invention provides a selenium rich paddy rice planting method. The selenium rich paddy rice planting method includes the steps: seed soaking and processing, transplanting, topdressing, field management, harvesting and other steps. Paddy rice seeds are soaked in selenium liquid, and is fertilized by selenium rich compound fertilizer for four times during the planting process, and the selenium rich compound fertilizer contains rich selenium. The selenium rich paddy rice planting method utilizes the compound fertilizer with rich selenium, high nitrogen content, high-quality humic acid, and organic trace element to improve the fertility of soil and increase growth speed of paddy rice plants, thus improving the utilization rate of fertilizer, reducing loss of fertilizer, and significantly improving paddy rice yields. So that the selenium rich paddy rice obtained through the method has high quality, and is healthy to eat and is nutrient-rich.

Description

technical field [0001] The invention relates to a compound fertilizer for agricultural production, in particular to a method for planting selenium-enriched rice. Background technique [0002] my country is a big agricultural country, and it is also a big country in the production and use of chemical fertilizers. The domestic use of chemical fertilizers has increased from less than 0.1% in 1949 to the vast majority of crops currently being planted with chemical fertilizers. At present, my country's total output and application of chemical fertilizers rank first in the world. . The status of fertilizers in rice production is very important, especially chemical fertilizers, which play a pivotal role in increasing agricultural production. The input of chemical fertilizers is increasing year by year. However, at present, the approximate range of the utilization rate of chemical fertilizers in the current season in my country's rice fields is: nitrogen fertilizer 30-60% for phospha...
