Special formulation fertilizer for rice

Abstract

The invention belongs to the technical field of fertilizers, and in particular relates to a special formula fertilizer for rice. It is characterized in that the weight percent of effective elements in the fertilizer in terms of pure nutrients is 25-15 nitrogen, 15-9 phosphorus pentoxide, 20-12 potassium oxide, 5-0 silicon dioxide, 8-0 calcium, and 5-1 sulfur and zinc 2-1. Compared with the prior art, the fertilizer-nutrient distribution ratio of the rice-specific formula of the present invention is reasonable, conforms to the nutrient absorption rule of rice, can obviously promote rice growth, increase rice yield, increase economic benefits, and improve rice nutritional quality. The application test shows that the special formula fertilizer for rice of the present invention can increase the yield of rice by 660-820kg per hectare, increase the income by 756-1468 yuan, and the brown rice rate, the whole polished rice rate, and the polished rice rate in the rice processing quality increase by 1.4%, 1.7% and 1.8% respectively. The white kernel rate and chalkiness decreased by 3.2% and 1.9% respectively, and the amylose content decreased by 1.0%. At the same time, fertilizer use efficiency increased by 5.1%-13.8%.

Description

technical field [0001] The invention belongs to fertilizers, in particular to a special formula fertilizer for rice. Background technique [0002] Rice is one of the main food crops that humans rely on for survival. Its sown area accounts for about 30% of the total grain area in my country, and rice production accounts for about 40% of the total grain output. Rice is the staple food of more than 60% of the population in my country, and the annual consumption of rice is about 190 million tons, accounting for 35% of the total grain consumption. Therefore, rice is the largest food crop in my country and bears the most important task of food security. [0003] In order to alleviate the pressure of population growth on food demand, my country has always regarded increasing the yield of rice per unit area as the main task of rice production. At present, the country's rice yield per unit area has exceeded 6t / hm 2 , which is higher than the world average level, and plays a very i...

Problems solved by technology

[0005] In terms of fertilizer application technology, although a series of fertilization technologies have been created, such as "two promotions and one control", "stabilization before improvement", "ball fertilizer deep application", leaf age mode fertilization, soil testing formula fertilization, one-time full-layer fertilization, etc. However, due to the lack of labor force currently engaged in rice production and most of them are the elderly, women and children, their cultural and technological quality is low, their ability to accept new technologies is poor, and the grassroots agricultural technology promotion team is unstable, it is difficult to popularize and apply good fertilization technology
