The 10th Regiment of the First Agricultural Division pioneers a new water-saving technique for dryland rice cultivation with drip irrigation under plastic film
In 2010, the 10th Regiment of the First Agricultural Division of the **Production and Construction Corps used new science and new technology to transform traditional agriculture. Faced with a severe shortage of water resources and its disadvantaged position as a unit downstream of the First Division's water supply, it independently developed new machinery for sowing rice on dryland with drip irrigation under plastic film, which was put into rice production and vigorously promoted by Aral City of the First Division. According to Kong Jun, the First Division's deputy division commander in charge of agriculture, this cultivation model not only saves labor in rice planting but also conserves water resources and farmland costs, helping to increase rice yields and efficiency, and it has opened a new chapter for the Corps' agriculture and livestock farms.

Scientific control methods for the first-generation Asiatic rice borer (Chilo suppressalis) in rice
According to surveys conducted across Hubei Province, the overwintering mortality rate of the Asiatic rice borer this year was higher than last year, and the post-winter population base was lower than last year but still relatively high. In addition, suitable climate conditions and the expansion of high-quality rice varieties are both favorable to the occurrence and damage of rice stem borers, and the first-generation Asiatic rice borer will show a major outbreak trend in the rice-growing areas of our province, making the control situation still severe. In response to this severe situation, all localities should strengthen leadership, raise awareness, actively organize control efforts, and quickly launch a campaign to wrest grain from the pests to ensure the safety of grain production. 1. Recognize the situation clearly and strengthen organizational leadership. Last winter, our province suffered freezing ice and
