The situation of rice production in Jilin Province is not optimistic this year

Introduction: in recent years, the area of rice growing by well water in some river rainfall collection areas has gradually increased, the groundwater resources have been damaged, and the drought has become more and more serious, resulting in a large amount of paddy fields in the downstream of some large reservoirs lacking water and the production situation is not optimistic Agricultural experts suggested that we should restrict the drilling of wells and rice planting in the rain collection area Jilin Province grows about 10 million mu of rice all year round Basically, river irrigation, water storage project irrigation and well water rice planting account for one third each CHEN Si, deputy director of Jilin Provincial Agricultural Committee, said: "one of the outstanding problems in the development of rice is the lack of downstream water resources caused by digging wells and planting rice in the rainwater collection and storage area At present, Liaohe River, Yitong River, Yinma River and wukai River are the main grain producing areas in the middle of China The problem of digging wells and planting rice in the rain collecting area in the upper reaches is very serious, which leads to the lack of water in large paddy fields downstream of large reservoirs such as Erlonghu reservoir in Siping City, Shitoukoumen reservoir, Shuangyang reservoir and Xinlicheng Reservoir in Changchun City In recent years, the government of Jilin Province has been controlling the development of rice planting area in view of the current situation of drought and water shortage From 2000 to 2002, it organized a large number of farmers to change paddy field to dry field, with an accumulated area of more than 2 million mu Due to the good water storage in autumn of 2003, and the increasingly popular market of high-quality Japonica Rice in Jilin Province, the price remains high Last year, a large number of rice was restored to the paddy field where the dry field crops were changed, and the rice area increased by 1.5 million mu According to Chen Si, the situation of paddy production in 2005 is not optimistic Main basis: first, since 1997, Jilin Province has entered the drought and flood cycle of 11 years The rainfall is decreasing gradually The minimum annual rainfall in Baicheng area is only 150 mm, which used to be more than 400 mm Now the serious drought in spring has been pushed to the first line of Siping in Changchun Especially serious years pushed to Liaoyuan and Meihekou Therefore, the spring drought cannot be ignored Second, before the autumn freeze in 2004, there was less rainfall, coupled with the high temperature in the winter before, and the evaporation of soil water was large Although the snow fell frequently in the later winter, the snow water did not play a role in the water shortage of paddy field in the plain area of the main grain production area Third, affected by the market and high price of Japonica rice, the enthusiasm of farmers to grow rice is increasing day by day, and the area of rice will not decrease in 2005 Fourth, the state supported the policy of "one exemption, three supplements" for major grain producing areas to continue to be implemented in 2005, with more subsidies for rice planting than for other crops, thus encouraging the enthusiasm of farmers to diversify rice Fifthly, due to the imbalance of precipitation last year, it is possible for farmers in water deficient paddy fields to continue to use well drilling and rice planting methods to increase the efficient paddy field area So how to solve this problem? Experts believe that Jilin Province should not take the road of expanding paddy field area, but take measures of drought resistance and water saving, and rely on science and technology to improve yield and quality in order to increase the supply and sales of high-quality refined rice Experts suggest that the government should solve the problem of water shortage in paddy field as a whole, and limit the continuous drilling of wells and rice planting in the rainwater collection and water storage area In addition, every effort should be made to save water and do a good job of water conservation in the project Special attention should be paid to the artificial precipitation enhancement in the rainwater collection and storage area to improve the effect and quality of artificial precipitation enhancement
