中国农科院气象室科技人员承担“七五”国家旱地农业攻关课题,在山西省屯留县将农用液态膜制剂系列引入晋东南地区,大力试验推广农业气象实用技术—农业化学,取得良好结果,受到长治市、屯留县政府的肯定和农民群众的欢迎.农用液态膜系列包括保水剂、抗旱剂和保鲜剂,它们主要针对干旱,充分发挥每种液态膜制剂对水分的调节控制机能,在作物生长的不同时期和阶段,达到吸水保水、抑制蒸腾、保墒增温、抑蒸防腐等目的,从而增强作物的抗旱能力,在产前、产中、和产后各时段形成完整的系列化的防早保水技术体系,达到有灾抗灾,无灾增产。经试验,小麦用
Chinese Academy of Agricultural Sciences meteorological room science and technology personnel to undertake “75” national dry land agriculture research topic, in Tunxi County, Shanxi Province, agricultural liquid film formulations introduced into the southeast of Shanxi Province, vigorously test the promotion of agricultural meteorological practical technology - agricultural chemistry, and achieved good results , Recognized by the governments of Changzhi City and Tunliu County and welcomed by peasants.The series of agricultural liquid films include water-retaining agent, drought-resistant agent and preservative, which are mainly aimed at the drought and give full play to the regulating and controlling functions of each liquid membrane preparation to water, In different stages and stages of crop growth, water absorption and water retention, evapotranspiration control, warming soil moisture preservation and anti-steeping and preserving purposes are achieved so as to enhance drought resistance of crops and form a complete serialized series of products at prenatal, intrapartum and postpartum periods Anti-early-water technology system, to disaster relief, disaster-free production. After testing, wheat
