Scientific prevention and control of high -yield rice yield is based on comparative trials. The contribution rate of plant protection to late rice production is nearly 50 %.

Hunan Province's rice diseases and insect pest prevention and control effects and plant protection contribution rate evaluation test site observation meeting was held today in Liling. Participants generally believed that rice diseases and insect pests were not defensive and the effect was very different. The expert group evaluated on -site that Ling Ling conducted a test of the effect of late rice disease and insect prevention and treatment. It is estimated that the contribution rate of plant protection to the yield of late rice reached 48.7%.

The reporter saw at the experimental site of Xishang Village, Sifen Town. The scientific prevention and control zone was 100 acres, and the guidance of the plant protection experts was listed. Essence In the completely incomparable control area, pests such as the secondized crickets, rice live lice, and rice vertical rolls are caused by harm. It can be seen that the phenomenon of withered and dry sheaths, and the "white ears" appeared in the group.

Rice diseases and insect pest prevention and control, high technical requirements. In the spontaneous prevention and control zone of farmers, the loss of pests and insect pests has been greatly reduced compared to the prevention of the zone. However, compared to the specialization of the demonstration zone of the specialization of the defense, it is estimated that the production is reduced by about 25%. Luo Wenhua, a large grain family who came to observe, said that after decades of rice, he can be considered "old -fashioned", but from the perspective of the prevention and control of pests and insect pests, he still has to listen to experts and not accept it.

The plant protection experts picked out the "disease plant" of the late rice in the field, peeled out each dry straw, and found the dizen. According to the on -site explanation, Erhua also is also known as the heartworm, which is the main pest of rice production in Hunan Province. Due to the long period of time and difficulty in preventing and control, the effect of specialization and prevention and control. Participating representatives directly opened their eyes. Pests and insect pests were different from those who did not prevent it. The effect was visible.

The relevant person in charge of the Ministry of Agriculture and Rural Affairs stated that Hunan carried out the effectiveness of the prevention and control of rice diseases and insect pests and the evaluation of the contribution rate of plant protection. The test design was scientific and reasonable, and the contrast effect was obvious. At the same time, the combination of agricultural science and education, the cooperation between the department, and the participation of social forces have set a typical example for the country.
