膜下滴灌对麦茬夏花生出苗质量和产量的影响

Effects of Drip Irrigation under Mulch on Seedling Quality and Yield of Summer Sowing Peanut

以生产上主推的花育22号为材料、大田机械化生产为基础、"干播湿出"技术为重点,研究了膜下滴灌对麦茬夏花生出苗质量和产量的影响。结果表明:与大水漫灌相比,膜下滴灌显著提高花生出苗质量,花生出苗时间提早近1d,烂种率显著降低,出苗率、幼苗整齐度、有效植株率均显著提高,着生第一对侧枝植株数、苗期叶面积和生物量均明显增加,农艺性状明显改善,膜下滴灌对产量提高具有显著效应。

Huayu22, one of the main planting varieties, was chosen as material. On the basis of mechanized production in the fields, dry-sowing and wet-germination technology is the key point. The seedling quality and yield of summer peanut with wheat stubble were studied for drip irrigation under mulch. The results showed that compared with flood irrigation, drip irrigation under mulch significantly improved the seedling quality. Peanut emergence time was nearly one day in advance, the rate of rotting was significantly reduced. Thus, emergence rate, neatness of seedling and effective plants rate were significantly improved. The plant with the first pair of side branches, leaf area of seedling stage and biomass markedly increased. Agronomic traits obviously improved. The drip irrigation under mulch significantly promoted the increase of yield.
