水稻稀少平高产栽培法的主要内容是,稀播种培育带蘖壮秧;减少每穴栽插苗数;实行肥水平隐促进。这种栽培法是遵循水稻高产规律,从水稻育苗到收获综合利用合理的栽培技术,超出过去单一强调“秧田稀播”、“小株密植”或“肥田宜稀”等合理密植的范畴。在我省中等以上地力、农田基本建设和栽培技术有一定水平的稻区,可以作为高产再高产或中产变高产的重要途径。但还是要强调因地制宜地加以运用。 据沈阳市农业局1982年在五个县区16点试验,采用稀少平栽培法,秧苗壮、穗粒兼优、纹枯病轻,平均亩产1,169斤,比对照田增产7.8％。我省水资源不足,实行稀播种、早育苗、肥水平稳促进、间歇灌溉的方法也有利于抗旱、省水、高产。稀播种的秧龄弹性较大,如因缺水延期插秧时,也可保证正常生育,减轻晚插对产量的影响。
The main content of rice rare high yield cultivation method is thin seedling cultivation with tiller seedling; reduce the number of planting per hole; implementation of fertilizer level implicit promotion. This cultivation method is to follow the law of high yield of rice, from rice seedling to the comprehensive utilization of harvesting reasonable cultivation techniques, beyond the single emphasis on the “seedling thinning”, “small plant dense planting” or “fertile fields should be thin” and other close planting areas. In middle and upper middle reaches of our province, fertile land with certain level of farmland capital construction and cultivation techniques can serve as an important way for re-yielding high-yielding crops or increasing middle-yielding crops. However, we must also emphasize that we should apply it according to local conditions. According to the Shenyang Bureau of Agriculture in 1982 in 16 counties in five counties, the use of rare flat cultivation method, seedling Zhuang, spike grain and excellent, light blight, the average yield of 1,169 kg, 7.8% more yield than the control field. Insufficient water resources in our province, the implementation of thin seeding, early nursery, fat and stable water to promote intermittent irrigation methods are also conducive to drought, water, high yield. Slender seeding seedling age greater flexibility, as a result of delayed watering seedlings, but also to ensure normal fertility, reduce late plug on the impact of production.
