【摘要】 为检验水稻盘育秧抛栽技术在我区的适应情况,寻求水稻生产新的高产节本增效途径,我们于 1996、1997连续 2a在西青区进行了水稻盘育秧抛栽技术试验研究项目,累计育秧面积 0.8hm2 ,实抛面积 4 6hm2 。通过配套技术措施的实施以及加强水肥管理及病虫害防治,2a平均产量达 4 5 3.6kg/(6 6 7m2 ),较对照增产 4 1.1kg/(6 6 7m2 ),新增效益 12 2.1元/(6 6 7m2 ),累计新增效益 8.4万元,累计节省用工成本 2.76万元,总创效益达到 11.16万元,达到了高产节本增效的目的。更多还原

【Abstract】 In order to examine the adaptation of the technology of rice seedlings raising in plates and cultivation by throwing to Xiqing district, and to seek for the new way of high yield, cost saving and effectiveness increasing in rice production, the experiment on the technology of rice seedlings raising in plates and cultivation by throwing was carried out in Xiqing district for two years continuously in 1996 and 1997. The total area of raising rice seedlings was 0.8 hm 2, and the practical throwing area was 46 hm 2. By the application of auxiliary technical measures, and by strengthening water and fertilizer management and also by prevention and control of diseases and pests, the average yield of two years is 453.6 kg/(667 m 2), 41.1 kg/(667 m 2)higher than control. The new increased benefits is 122.1 yuan/(667 m 2), and the total increased benefits is 84 000 yuan, the total cost saving for labors is 27 600 yuan. Thus the total increased benefits reach 111 600 yuan and the aim of high yield, cost saving and effectiveness increasing is reached.更多还原
