水稻全程地膜覆盖湿润栽培是改造低产水田、促进水稻高产的一项新技术。通过对10个试验点产量的统计分析,水稻全程地膜覆盖湿润栽培比对照增产1291.5kg/hm2,增19.7%,达极显著水平。对产量因子的分析表明:该项技术能够有效地增加有效穗、穗总粒和穗实粒,分别增加11.3%、10.7%和10.5%,而千粒重的提高则不明显。该项技术在具体操作上,要严把杂交种、旱育秧、全层肥、湿润管、群体优5个技术关键。
Moisture cultivation of rice covering the whole film is to transform low-yield paddy fields, and promote high-yielding rice is a new technology. Through the statistical analysis of the yield of 10 experimental spots, the whole mulching rice cultivation increased 1291.5kg / hm2 and 19.7% more than the control, reaching the extremely significant level. The analysis of yield factors showed that the technology can effectively increase the effective panicles, spikelets and spikelets by 11.3%, 10.7% and 10.5% respectively, while the increase of 1000-grain weight is not obvious. The technology in the specific operation, to be strict hybrid seedlings, dry nursery seedlings, full-thickness fertilizer, moist tube, the group of five key technical superiority.
