进行了人工露地点播、人工地膜覆盖点播和机械地膜覆盖点播花生的经济效益比较试验 ,结果表明 :地膜覆盖能够改善花生生长发育的环境条件 ,促进花生营养器官的发育功能 ,提高生产潜力和花生的质量和品质 ;人工地膜覆盖的经济效益优于露地点播 ;机械覆膜与人工覆膜的经济效益比较 ,每工日劳动力价格临界值为 12 .8元 ,超过这一临界值 ,机械覆膜优于人工覆膜。
The results showed that the plastic film mulching could improve the environmental conditions of peanut growth and development, promote the developmental function of vegetative organs of peanut, increase the production potential and increase the productivity of peanut Quality and quality; the economic benefit of artificial mulching is better than that of open-field; comparing the economic benefits of mechanical mulching and artificial mulching, the critical value of labor cost per working day is 12.8 yuan; beyond this critical value, In the manual coating.
