Jiangsu symptomatically solves the problem of using medicine for characteristic economic crops

With the rapid development of high-efficiency agriculture, specialty cash crops such as vegetables have become the pillar industries of agricultural efficiency and farmers' income increase in many places. In view of the fact that some special cash crops have few registered pesticide products, and there are problems of over-range drug use and drug abuse in the production process, the agricultural department of Jiangsu Province organized the screening of drug use for vegetables and other special cash crops, and guided farmers to use pesticides scientifically and strive to improve the quality and safety of agricultural products. Level.

 Release time : 2020-05--09  Hits : 0

Pyraclostrobin （Kairun, pyraclostrobin） is named because it has one more pyrazole ring in the molecular structure than that of pyraclostrobin. It has all the characteristics of methoxy acrylate fungicides, and has the functions of protection, treatment and leaf penetration and conduction. Its performance and application range are similar to that of azoxystrobin.

 Release time : 2020-05--09  Hits : 0

　　It is suitable for controlling rice, vegetables and cotton, and has a high activity against various pests such as Lepidoptera, Hemiptera, Orthoptera, Coleoptera, Diptera and Isoptera. Other azoxystrobins have protective and therapeutic effects, and have permeability and systemic activity. It can be used for stem and leaf spraying, seed treatment and soil treatment. It has good control effect on grape powdery mildew and apple scab. Mycotoxin not only has a broad spectrum of bactericidal activity, but also has good protection and therapeutic effects. 　　Promethoxone has no cross-resistance with other commonly used fungicides and has a longer shelf life than conventional fungicides. Mycotoxin is highly selective, safe for crops, humans and animals, and beneficial organisms, and basically has no pollution to the environment. It has no systemic effect on crops and requires uniform and thorough spraying. Insect pests should be sprayed before they reach the crops. Do not mix with strong alkaline pesticides. Permethrin is the only pyrethroid pesticide allowed to be registered on rice. 　　Fast-acting and long-lasting properties are better than pymetrozine and nitenpyram. Since 2009, pyrethrin has been listed as a key product for promotion by the National Agricultural Technology Extension Center. Since 2009, plant protection stations in Anhui, Jiangsu, Hubei, Hunan, and Guangxi have included pesticides in key promotion varieties of plant protection stations.

my country’s 3,000 green super rice genome original sequencing data shared from the "cloud" to the world

 Release time : 2015-09--21  Hits : 0

　　On September 15th, the Chinese Academy of Agricultural Sciences, Alibaba Cloud Computing Co., Ltd., Huazhi Rice Biotechnology Co., Ltd., and Beijing Judao Technology Co., Ltd. jointly launched the “Cloud Rice Project” in Changsha, with 3,000 raw sequencing data of the green super rice genome. It will be officially opened to the world through the Alibaba Cloud platform for free. This is not only conducive to accelerating large-scale discovery of excellent rice genes, breaking the technical bottleneck of rice complex trait molecular improvement, but also accelerating the process of breeding new varieties with high yield, high quality and wide adaptability, and comprehensively improving the level of rice genome research and molecular breeding in China and the world. . 　　3,000 copies of rice core germplasm genome sequencing data from 89 countries around the world are important project achievements of the “Major Science and Technology Project” of the Ministry of Science and Technology and the Bill Melinda Gates Foundation for the cultivation of green super rice in resource-poor regions in Africa and Asia This is by far the largest plant genome sequencing project in the world. The project aims to cultivate new rice varieties that can be widely applied to the ecological environment of irrigation and rain-fed areas, and have the characteristics of efficient use of nitrogen and phosphorus, disease resistance, insect resistance, high yield, high quality, stress resistance （drought, salt and alkali）, etc. China's demonstration and promotion to promote hybrid rice seed production capacity and establish an efficient rice genotype analysis technology platform for rice molecular breeding in sub-Saharan African countries, Asia and Southwest China. 　　Genome sequencing for rice core germplasm is a huge project. The gene database resource has at least two uses. One is to retrieve data from the gene library and study the distribution, evolution, and function of the target gene. The second is to analyze polymorphic sites between genomes and use them to develop molecular markers and even gene chips for molecular breeding. By sequencing the genome analysis of 3000 core rice germplasm, we can answer the question of how much genetic diversity of rice can be applied and where to obtain the genetic resources needed for biological breeding. The data obtained from the analysis will provide basic information for basic understanding of rice and biological breeding Resources. This research can reveal the genomic diversity of global cultivated rice resources, as well as the genetic characteristics and application value of each rice resource. In addition, bringing 3,000 rice germplasm resources to rice breeding applications will provide materials and new ideas for innovation in rice breeding. The analysis of the data will also fill people's knowledge gap in genomics about rice and even various species. 　　According to experts, when the rice genome research meets “cloud computing”, it will produce great magic. For example, the deficiencies of the newly-exited “Liangyou 0293” variety is that the resistance to rice blast is relatively poor, and the 3,000-point rice genome study will rely on the “Yunzhi Rice” project. Within three years, not only can you find more There are many disease resistance genes, and it is expected that the resistance of new varieties of rice blast will be improved to above 3, so that relatively comprehensive new rice varieties such as yield and resistance will be cultivated, and the adaptability of super rice varieties will be better and wider.
