摘要
研究了几种早熟栽培措施对红芽芋 (ClocasiaescalentaSchott)生长和产量的影响 ,结果表明 :以大棚加地膜覆盖的催芽效果最好。其中 ,催芽处理植株高、整齐度好 ,叶片抽生速度快 ,比未催芽处理增产 2 6 .1% ,增产达极显著水平 ;地膜覆盖可改善土壤耕层的气候条件 ,比露地栽培产量提高 6 0 .75 % ,增产达极显著水平。不同播期的试验表明 ,提早播种能极显著增加产量。越早播种并加地膜覆盖的增产效果越明显。增施基肥有机肥和追肥能极显著提高红芽芋产量。
Effect of several early maturing culture ways on growth and yield of red sprout Clocasia escalenta was studied. The results showed that plastic mulch with shed has the best effect on germination hastening. Germination hastening were taller and more regular in plant height and faster in leaf growth speed. The yield of germination hastening was higher of 26.1% than that of no germination hastening. The difference was very significant. The soil climatic condition was improved by plastic mulch. The yield of plastic mulch was higher of 60.75% than that of in open cultivation. The difference was very significant. By sowing in different dates, the results showed it was very significant that pre-seeding had raised yield. Early and early seeding time, the effect of plastic mulch covering on raising yield was better and better. Add organic fertilizer to subsoil and additional fertilizer can very significantly raise yield.
