Fertilization method capable of improving eating quality of rice with excellent eating quality

Abstract

The invention discloses a fertilization method capable of improving the eating quality of rice with excellent eating quality. The fertilization method comprises the following steps: before seedling transplanting, applying organic fertilizer as basic tiller fertilizer, and performing rotary tillage for making the organic fertilizer penetrate into mud; respectively applying urea as tiller fertilizer on the 5th day and the 12th day after seedlings are transplanted; and at the top fourth leaf age, applying organic fertilizer as panicle fertilizer, wherein the total amount of pure nitrogen of the applied fertilizer is 150.0kg / hm<2>, and the mass ratio of the basic tiller fertilizer to the panicle fertilizer is equal to 9:1. A fertilizer application strategy conforms to the principle of applying the enough basic tiller fertilizer, stably applying the tiller fertilizer and properly applying the panicle fertilizer, and especially, during a late growth stage, nitrogen fertilizer is not applied while organic fertilizer is applied as much as possible. According to the invention, by selecting the proper fertilizer ratio, the fertilizer efficiency of the organic fertilizer is brought into full play, the nutritional requirement of the rice variety with excellent eating quality during the whole growing process is effectively met, the eating quality of the rice is improved on the premise of guaranteeing certain yield of the rice with excellent eating quality, the economic benefit of the rice variety with excellent eating quality planted by farmers is increased, and the large-scale plantation and the industrial development of the rice are facilitated.

Description

technical field [0001] The invention relates to a fertilization method for improving the eating quality of good-tasting rice, which belongs to the technical field of rice planting, and specifically relates to a fertilization method for improving the eating quality of rice under the premise of ensuring a certain yield during the cultivation of good-tasting rice varieties. Background technique [0002] With the development of my country's economic level and the change of consumption structure, people's demand for high-quality rice, especially high-quality rice, has increased rapidly, and some high-grade rice with better quality has been favored in the market (Li Junhui, Zhu Zhiwei, Xie Lihong, my country Rice Research status and development trend of eating quality. China Rice, 2008, 2: 8-12). Therefore, the production of high-quality rice, especially rice with good taste, not only has a broad market prospect, but also an important way to enhance the international competitivenes...

Problems solved by technology

Although the eating quality of rice is mainly determined by the genetic characteristics of the variety, the amount of fertilizer also has a significant impact on the expression of this trait

Increasing fertilizer application within a reasonable range can indeed effectively increase rice yield under the premise of ensuring yield. However, if it is unreasonable, it will also lead to a decrease in fertilizer use efficiency. Serious decline (Zhu Changlan, Zhai Huqu, Wan Jianmin.
