Silicon-zinc fertilizer application method for improving quality of japonica rice

Abstract

The invention belongs to the technical field of rice planting, and discloses a silicon-zinc fertilizer application method for improving the quality of japonica rice. A soil dressing and leaf surface silicon-zinc fertilizer spraying method is adopted, the soil dressing period is the inverted four-leaf period, the silicon fertilizer is an instant silicon fertilizer, the leaf surface spraying period is the booting period, the zinc fertilizer is zinc chloride, and nine treatment levels are set in total; each treatment is repeated for three times, and each cell is 16 m < 2 >. According to the silicon-zinc fertilizer application method for improving the quality of the mid-ripe japonica rice, south japonica 46 is taken as a research material, the influence of different silicon-zinc fertilizer dressing modes on the yield and quality characteristics of the rice is researched, and a reference is provided for optimization cultivation of the variety. According to the method, the silicon-zinc fertilizer is dressed to the soil, so that the taste quality is best, the taste value reaches 90.6, the amylose content is relatively high, the disintegration value is highest, the reduction value is lowest, the chalky rice rate and chalkiness degree are lowest, the brown rice rate is highest, and the yield is also highest and reaches 756.88 Kg / mu.

Description

technical field [0001] The invention belongs to the technical field of rice planting, and in particular relates to a silicon-zinc fertilizer application method for improving the quality of japonica rice. Background technique [0002] At present, with the development of the economy and the improvement of people's living standards, the public has higher and higher requirements for the quality of rice. Reasonable cultivation methods are the main way to improve the quality and yield of rice. Silicon is an essential element for rice growth, its role is second only to nitrogen, phosphorus, and potassium, and it plays an important role in the growth and development of rice. Zinc acts as a nutrient manager in plants, and plays a role in coordinating the distribution of nutrient elements in the body. Rice is a plant that is more sensitive to zinc deficiency. Zinc deficiency will delay the growth and development of rice, reduce the stress resistance of rice, and reduce the number of t...

Problems solved by technology

[0003] Through the above analysis, the problems and defects in the prior art are: the existing rice fertilization method will delay the growth and development of rice, reduce the stress resistance of rice, and finally reduce the yield; the quality of rice obtained at the same time is not good
