上海市松江区家庭农场种植业茬口布局实践与对策

Practice and countermeasures of the family farms' crop disposition in Songjiang District

调查了松江区家庭农场种植业茬口模式(秋播种植二麦、绿肥和深翻各占1/3的茬口布局)对稻麦产量、土壤肥力、生态环境、种植效益等的影响,分析了当前茬口布局存在的问题及对策。结果表明,"三三制"种植业茬口模式不但有效解决了家庭农场在稻麦收种阶段机械、劳力与适时播种的矛盾,而且培肥了土壤,改善了生态环境,有利于实现稻麦持续稳产高产。

The family farms＇crop farming was surveyed in Songjiang District to investigate the rice and barley（or wheat）yields, soil fertility, ecological environment and economic results as influenced by the rotation system in which the areas of barley（or wheat）,green manure and subsoiling accounted for 1/3 each in autumn, and the problems and countermeasures of the existing crop disposition were dis cussed. The practice showed that the＂three course system＂ not only effectively solved the contradic tions in machinery,labor and timely sowing of family farms in rice and barley（or wheat）harvesting time, but also improved the soil fertility and ecological environment, being conducive to high and sta ble yields of rice and barley/wheat.
