一、试验研究的目的 镇江市地形复杂,有低山丘陵,又有沿江圩区和太湖平原。低山丘陵区岗坡地高旱且土质贫瘠,沿江圩区及太湖平原区地下水位较高,土质粘烂,对小麦生长不利,能否推广精少量播种技术?采用什么类型的播种机进行精少量播种?于是,我们根据镇江市科委的安排,于1998年着手进行小麦机械精少量播种的试验与研究。 二、试验内容与试验方法 (一)排种器选型试验:试验用排种器型号为塑料外槽轮式半精量排种器,分16槽直槽和斜槽两种,淮阴市农机所研制的“江淮JH—A型小
First, the purpose of experimental research Zhenjiang City complex terrain, hilly, polders along the Yangtze River and the plains. Hilly area of hillock high drought and poor soil quality, along the polders and the Taihu Lake plain higher groundwater levels, soil sticky rot, adversely affect the growth of wheat, can promote fine sowing techniques? What type of planter for fine amount Therefore, according to the arrangement of Zhenjiang Municipal Commission of Science and Technology, we started the experiment and research on small precision sowing of wheat machinery in 1998. Second, the test content and test methods (A) Seeding device selection test: The experimental model with a plastic seeding wheel semi-precision seed metering device, divided into 16 slots straight slot and chute two, Huaiyin Agricultural Machinery Developed by "JAC JH-A small
