Rice blast is a quarantine disease on rice, which has a great impact on rice yield and quality, in order to explore the effective pharmaceutical agents for controlling rice blast. A pilot study was conducted in 2001 with better results. It is summarized as follows: 1, materials and methods X-Ray Protection,Medical X-Ray Films Powder,Developer And Fixer Powder,X-Ray Films Powder Ningbo Cland Medical Instruments Co., Ltd. , https://www.cland-med.com
1.1 The test agent was "Living Kang Zhuang" and was provided by the Ministry of Development of Active Health Zhuangfeng. The test variety was rice.
1.2 Test setup: The test area is 2 mu. The test is provided with one treatment, one control, and three replicates. The test was sprayed on August 10, 15, and 20, 2001, once each time, and the control sprayed water.
2. Field investigation: After the heading, the incidence of rice blast disease was investigated. At the ripening stage, sampling was conducted at 5 points per acre to measure the yield.
3, the results of analysis
3.1 Disease prevention effects A total of 500 strains were investigated. 16% of the diseased strains were active and robust, and the diseased plant strains were relatively mild. The control strains were 81%, and the diseased plants were severely diseased.
3.2 Effect of increasing production After being verified by the measured production, the “live and strong†community uses an average yield of 938 kg per mu with an output value of 1031.8 yuan, 816 kg per mu compared to the control, and an increase of l22 kg, which is 897.6 yuan more than the control, and the value-added is 134.2 yuan. %.
4. The summary test showed that "Living Kang Zhuang" is the best drug for controlling rice blast, and it should be sprayed locally in August to best prevent and cure ear blast, and also to promote rice growth, root growth, and conservation. The functions of preserved flower, pellets, etc., have extensive application value.
(Note: Because rice blast disease is divided into several species, some are borne by seeds and spread by soil. It is recommended to use “Kang Kang Zhuang†to control rice blast disease. It should be combined with seed dressing to prevent and control rice at the early stage of disease induction.)
