1992~1994年的试验示范表明,早稻应用早育秧栽培技术,秧苗根系发达,抗逆力强,栽后返青分蘖快,个体发育好,穗粒优势明显,比常规水育秧栽培亩增55.6kg,增产13.6%,且能早播早熟。主要技术是用栏肥培肥秧床,用丁草胺除草,3月10~15日播种,每平方米播种140g,5.5叶移栽,大田密植30cm×13.3~16.7cm,常规稻每丛插3~4本,杂交稻每丛插1~2本,大田亩施有机肥750kg,施化学纯氮7.5~8.5kg。
The experimental demonstration from 1992 to 1994 showed that the early seedling cultivation techniques were used in early rice. The root system of developed seedlings was strong, the resistance was strong, the tillering speed was high after transplanting, the individual developed well, and the spike grain had obvious advantages. Compared with conventional aquatic seedling cultivation, the acreage increased by 55.6kg , An increase of 13.6%, and can sow early maturity. The main technique is to use column fertilizing fertilizer seedbed, butachlor weeding, March 10 to 15 sowing, sowing 140g per square meter, 5.5 leaf transplanting, field planting 30cm × 13.3 ~ 16.7cm, conventional Rice inserted 3 to 4 per bundle, hybrid rice inserted 1 or 2 per bundle, field Mushi organic fertilizer 750kg, applied chemical nitrogen 7.5 ~ 8.5kg.
