Double-cropping rice yield in kilograms per mu reaches a new high! High rice yield requires “good seeds and good methods”

Judging from the current rice market, high quality is the mainstream of marketization, and high yield is the key to ensuring planting efficiency. Many experienced growers also say that the key to growing rice is still yield.

When it comes to high yield, we have to mention the recent attention-grabbing yield of 1,365 kilograms per mu. What exactly is it? Let’s take a look.

Judging from the current rice market, high quality is the mainstream of marketization, and high yield is the key to ensuring planting efficiency. Many experienced growers also say that the key to growing rice is still yield.

When it comes to high yield, we have to mention the recent attention-grabbing yield of 1,365 kilograms per mu. What exactly is it? Let’s take a look.

The double-cropping rice yield per mu reached a record high of 1,365 kilograms

It is reported that in the on-site yield testing and acceptance of early and late rice organized by the Hunan Agricultural Society in July and November this year, both early rice and early rice were The yield per mu is 591.7 kilograms, the average yield per mu of late rice is 773.3 kilograms, and the combined average yield of two-cropping rice is 1,365 kilograms per mu, creating a new high in double-cropping rice production in my country.

This "achievement" is about 30% higher than the average double-cropping rice high-yield area, and about 50% higher than the average double-cropping rice yield per mu in Hunan. At the same time, the demonstration area saves fertilizer, costs, and economic and ecological benefits. The benefits are also particularly significant.

The so-called double-cropping rice is a rice farming system in which two crops of rice are planted and harvested in one year in the same rice field.

This time, the team of Yuan Longping, an academician of the Chinese Academy of Engineering, presided over the "13th Five-Year Plan" national key research and development plan for scientific and technological innovation for high grain yield and efficiency - "Hunan Double-cropping Rice Anniversary Green High-quality High Yield and Efficiency Technology Integration and In the "Demonstration" project, it not only set a production record of 1,365 kilograms, but also achieved safe, high-quality, high-yielding and efficient full-process green production of rice by combining high-quality and high-yield rice cultivation technologies with full mechanization.

High rice yield requires a combination of "good seeds and good methods"

In recent years, rice breeding has made great progress, more and more rice varieties have been approved, and there are more high-quality rice varieties with high yield and high quality.

One of the hot topics in the seed industry this year is "third generation hybrid rice technology", which is currently entering the application and transformation stage and may further increase the yield of hybrid rice. In this regard, Academician Yuan Longping said: "The third generation hybrid rice technology "Generation hybrid rice technology allows ordinary farmers to obtain a yield of more than 1,000 kilograms per mu using conventional cultivation methods."

With good varieties, we also need good production areas (good fields) and corresponding cultivation methods (good methods).

The cultivation techniques adopted in some experimental demonstration fields in my country mainly focus on technical points such as accurate water and fertilizer supply, precise seedling insertion, and prevention of premature aging in the later stage.

Precise quantitative rice cultivation technology is an advanced high-yield cultivation technology. According to the basic rules of high-yield rice cultivation, based on the target yield of the crop, different stages of growth and development, soil fertility, and demand for the season, etc., Accurately determine the supply of water and fertilizer.

This technology is being widely used in existing rice cultivation in various places. In recent years, it has been used in the creation of high-yield rice in southern Jiangsu, creating a large number of high-yielding recipes with a yield of 650-700 kilograms per mu.

At present, our country will continue to improve its technology in cultivation management. Cultivation is not based on experience, but can be managed quantitatively.

Achieving such results is inseparable from the rationally designed cultivation techniques of the expert technical team.

Growers should also pay more attention to the progress of rice breeding and cultivation technology, learn to summarize planting experience and manage carefully.
