近些年,福建上杭县芋农在芋叶开始满垄,即有5~6片芋叶、株高1.2~1.3米时,亩淋施600~700克多效唑来控制芋苗生长,以减少叶面积,增厚叶肉,增粗芋柄,从而提高抗性、品质和产量。但这种做法导致多效唑在作物、土地中严重残留,影响后茬作物生长,是一种不可持续的做法。近年来,有技术人员通过综合各地做法,提出了一种绿色安全生产办法。1.剥残叶、除芋荪。①剥残叶。剥叶有利芋田通风透光,减少养分消 In recent years, Fujian, Shanghang County, taro farmers began to full ridge, that is, 5 to 6 taro leaves, plant height of 1.2 to 1.3 meters, acres of leaching 600 to 700 grams of paclobutrazol to control taro growth to reduce Leaf area, thickened mesophyll, thick taro taro, thereby improving resistance, quality and yield. However, this approach has led to the serious residues of paclobutrazol in crops and land and the subsequent growth of stubble crops. This is an unsustainable practice. In recent years, technicians have put forward a green safe production method by comprehensively taking the practices of all parts of the country. 1. Stripping the leaves, except taro sun. ① stripping the leaves. Leaf stripping taro favorable ventilation, reduce nutrient consumption
