去年,我们大队放养了夏萍一千二百多亩,占全大队水稻总面积近六成。为夺取晚造粮食丰收创造了良好条件。在实践中,我们初步总结了夏季放养红萍的水肥管理和防治病虫害的做法: 一、水的管理红萍是水生作物。萍体浮在水面,萍面接触空气,萍根点到泥面,过高的水温、气温、土温都直接影响红萍的生长。其生长的适温是25℃左右。30℃以上,随着温度的不断升高,红萍就由繁殖不快到抑制生长直至死亡。我们通过大量的萍田温度量测,认识到:在我们地
Last year, our brigade stocked Xia Ping with 1,200 mu, accounting for nearly 60% of the total paddy area of the entire brigade. In order to seize the late harvest of food created a good condition. In practice, we initially summed up the management of water and fertilizer and the prevention and control of pests and diseases during the summer stocking of rhizome. First, water management Rhodiola is an aquatic crop. Ping body floating in the water, Ping Ping exposure to air, Ping root point to the mud surface, high water temperature, temperature, soil temperature directly affects the growth of Hongping. The temperature of its growth is about 25 ℃. More than 30 ℃, with the rising temperature, Red Ping by the proliferation of unhappy to inhibit growth until death. Through a large number of Ping Tin temperature measurement, we realized: in our place
