Planting method of rice rich in strontium

Abstract

The invention provides a planting method of rice rich in strontium. 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 a strontium solution, the compound fertilizer which is rich in strontium is applied for four times in the planting process, and the compound fertilizer which is rich in strontium contains rich strontium elements. According to the planting method of the rice rich in strontium, the compound fertilizer which is rich in the strontium element and high in nitrogen content and comprises high-quality humic acid 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 strontium-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 30-60% for phosphate ...

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 brought into full play, which limits the increase of rice yield, ultimately affects the economic benefits of farmers and brings a series of ecological and environmental problems

[0004] Planting paddy fields year after year not only absorbs a large amount of nitrogen, phosphorus, potassium and a certain amount of calcium, magnesium, sulfur, iron and other elements from the soil every year, but also absorbs a small amount of chlorine, zinc, manganese, boron, and copper. Molybdenum, molybdenum and other trace elements are about 10 times that of nitrogen. A large amount of various nutrients are absorbed, and some of them are lost by leaching. The supplement of inorganic fertilizers alone is far from meeting the needs of rice production.
