Mu yield 634.7 kg! The yield of special varieties for rice and shrimp co-cultivation in Jiangsu reached a new high

On October 22, the reporter of Science and Technology Daily learned that at the national rice industry system "green, high-quality and high-efficiency rice new variety cultivation and demonstration and Jiangsu modern agriculture (Crayfish) industrial technology system rice shrimp co-cultivation special rice 'shrimp excellent 100' on-site production test and observation meeting" held in Qingfeng Village, Touqiao Town, Guangling District, Yangzhou City, Jiangsu Province, the province's first rice and shrimp co-cultivation special variety "Shrimp Excellent 100" selected and bred by agricultural scientific research in Jiangsu Lixiahe area, demonstration planting to create high yield and high efficiency
。 The production test of the expert group on the same day showed that the average mu yield reached 634.
7 kg, which was more than 100 kg
higher than the national standard for special varieties of rice and shrimp.

"'Shrimp You 100' is a three-line hybrid indica rice variety, which is a project for us to organize scientific researchers to focus on the defects of general varieties in rice and shrimp co-cultivation that are not resistant to flooding, poor disease resistance, low yield and poor rice quality
.
After five consecutive years of research and the use of biomolecular breeding technology, the province's first special variety for rice and shrimp co-cultivation has passed the examination and approval of new rice products in Jiangsu Province this year, and has been planted in Yangzhou, Huai'an and other places for demonstration planting of more than 5,000 mu, and will enter a large area next
year.
Researcher Li Aihong, director of the Institute of Agricultural Sciences in Lixiahe Area, Jiangsu, said
.

It is worth mentioning that this variety has won the gold award of "Suitable Yangzhou Fried Rice Rice", and its cultivation has solved the key problem of
the development of the local industrial chain of Yangzhou fried rice.

Researcher He Jinlong, director of Jiangsu Seed Management Station, introduced that "Shrimp You 100" has green leaves, straight leaf posture, strong tillering power, moderate plant type distribution, good group neatness, good color change during maturity, and strong
resistance to falling.

"'Shrimp You 100' in terms of cultivation technology, we guide the demonstration base to carry out early sowing at the appropriate time in accordance with the requirements of production standards, sowing seeds in early May, the seed amount of field acres is about 1 kg, the seedling age is about 30 days, 15,000-20,000 holes are planted per mu, and after transplanting live trees, you can go to the water to raise shrimp, pay attention to the application of special biological fertilizers for shrimp farming, pay attention to maintaining deep water during the pregnant ear and flowering period to reduce the impact of high temperature hazards, and pay attention to drainage and shelving in the later stage to harvest
in time.
" Li Aihong said
.

Zhang Jiahong, a researcher at the Institute of Agricultural Sciences of Lixiahe District, Jiangsu Province, introduced that at present, Jiangsu Province agricultural science and technology independent innovation Qingfeng Village rice field comprehensive cultivation "one rice and three shrimp" demonstration base, is the use of rice field to raise crayfish, harvest one season of rice, two stubble adult shrimp and one shrimp fry in different time periods, has been summarized and refined into rice, shrimp, grass, fertilizer, water, medicine, bacteria, oxygen, bait, enemy, bottom, algae key content of new technology, follow the "three green" concept of green breeding, green nutrition and green prevention and control, can not only achieve stable increase in rice yield, The improvement of rice quality, raising large and good-quality crayfish, can greatly improve the efficiency of rice shrimp farming, can also greatly reduce the amount of pesticide and fertilizer application, and play a good role
in protecting the water quality and soil of rice fields.
