Drought-resistant drought-resistant hillside planted baby rice

In September, the farmers of Dujiangyan City in the town of Dujiangyan were surprised to find that in the township, on a steep and dry hillside, there was a golden rice wave!

After learning about this news, the reporter immediately went to the interview. On September 20th, the reporter walked into this sloping land covered with rice. I saw a single rice plant that was not high enough in individual rice varieties, and had more and fewer cultivars. However, they all grew well.

The area of ​​the slope is 2.4 acres. In the eyes of local villagers, the yield of rice above it is only about two or three hundred kilograms, and there is no big seed at all; but in the eyes of experts, it is a treasure, and the rice planted is even more priceless. "This is our country. The first new dryland rice variety obtained through heterologous hybridization has broad prospects for research and application. Zeng Xianping, a rice expert from the Provincial Academy of Agricultural Sciences, told reporters with excitement.

"Original Breeding to Obtain Drought-resistance Characteristics of Sorghum." The exact name of the new dryland rice is called "Sorghum-Rice". It is an expert in the United States Zhu Peikun's application of original chromosome hybridization technology to introduce the drought-resistant chromosome fragments of sorghum into southern rice recipient cells. Through the reorganization and hybridization of chromosome fragments, a new dryland rice variety with high drought resistance characteristics was obtained.” Zeng Xianping described the new variety accurately.

Zeng Xianping told reporters that traditional hybridization techniques are sexual hybridization techniques and are generally carried out among homologous plants, such as hybrids of rice and rice, and sorghum hybrids with sorghum. It is very difficult to hybridize heterologous plants and the success rate is very low. This unique technology opens the door for the cross-breeding of heterologous plants. “Let's see a new dawn in the application of science and technology.” Moreover, unlike genetically modified plants, chromosome hybridization occurs between plants that people eat daily. It is psychologically easy for consumers to accept.

Small amount of water should be cultivated on farmland. "The current output of this species is relatively low, because it is still an intermediate product and needs continuous improvement. If the cultivation techniques are also followed, there will be no problem with 500 kg per mu." The current status of the “rice” production is relatively low, Zeng Xianping explained.

The success of on-demand “Sorghum-Rice” on this hillside site not only attracted local villagers to visit, but also attracted the attention of the National Industry Technology Innovation Committee. "China's agricultural water accounts for 70% of the total water use, and rice water accounts for 70% of the country's water consumption." In an interview with reporters, Zhu Peikun said, "The newly-cultivated "Sorghum-rice" is drought-resistant and drought-resistant. To compete for water, rice can be cultivated on land that is suitable for agriculture. It is one of the ways to solve the problem of national food security."

“We use 1000 square meters of water for one acre of rice and only 10% for traditional rice.” Zeng Xianping added: “Sorghum-rice” rice seedlings can be grown like wheat and corn without germination after germination. Live broadcast; relying on natural precipitation to complete the growth and development, in Dujiangyan City only 105 days of growth; if the use of three-line technology to make this dryland rice into hybrid rice, is expected to yield 1200-1500 kg per mu, "these advantages show that The research and application prospects of this species are very broad."
