1980年我场第一年大面积试种直播稻,平均亩产超过650斤,个别条田达到800斤,科研站种植的试验田亩产927.斤。81年全场晚稻面积万亩,其中直播稻面积1300亩,平均亩产800斤,成熟收获前考查测定,全场亩产超过900斤的16条(面积在35～60亩)条田,其中有6条是直播稻,这6条田比另7条同品种插秧田的单产,加权平均后相比较产量接近(见表)。种植直播稻的面积比例应该适当,过大就难掌握,产量难以保证。根据农场实际情况,直播稻面积以占水稻总面积的20～25％为宜。种好直播稻应注意以下几个问题:
In the first year of my field in 1980, a large area was planted with direct-seeded rice, with an average yield of over 650 kg per mu and 800 kg of individual strips. The experimental plot planted at the research station produced 927 kg of mu. 81 years of late rice area of mu, of which 1,300 acres of direct seeding rice, the average yield of 800 pounds, mature before harvest test test, the audience more than 900 pounds per mu 16 (area of 35 to 60 acres) fields, of which Six of them were direct seeding rice, which were close to the yield of the same breed in the same field and the yield was close to the weighted average (see table). The proportion of areas planted with direct-seeded rice should be appropriate, too difficult to grasp, yield is difficult to guarantee. According to the actual farm conditions, the area of direct seeding rice accounts for 20-25% of the total area of paddy. Direct broadcast of rice should pay attention to the following questions:
