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 ...

Abstract

The invention provides a planting method of rice rich in selenium and chromium. The planting method comprises the following steps of: soaking seeds, transplanting rice seedlings, applying a fertilizer, carrying out field management, harvesting and the like. The rice seeds are soaked by selenium and chromium solutions, the compound fertilizer which is rich in selenium and chromium is applied for four times in the planting process, and the compound fertilizer which is rich in selenium and chromium contains rich selenium and chromium elements. According to the planting method of the rice rich in selenium and chromium, the compound fertilizer which is rich in the selenium element and high in nitrogen content and comprises high-quality humic acid and organic trace elements is utilized to improve soil fertility and promote the rapid growth of rice plants, the utilizing rate of the fertilizer is increased, fertilizer losses are reduced, rice yield is obviously increased, and the rice is high in quality, healthy to eat and rich in nutrients.

Description

technical field [0001] The invention relates to a compound fertilizer for agricultural production, in particular to a method for planting selenium-rich and chromium-rich 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 30-6...
