石油助长剂是山东淄博红旗化工厂生产的一种新型的植物刺激素。喷施后能够提高叶片含水率、增强保水能力、加强光合强度,减弱呼吸强度,在干热风发生时,喷施石油助长剂的麦田可以使叶片含水率增加5—28%,叶面蒸腾强度减少600—3,0002毫克/克/小时,有利于有机物质的制造和积累,使植株生长健壮,增强抗干热风的能力。1975年我们地区共喷施33.8
Petroleum Additives is a new type of plant stimulating hormone produced by Shandong Hongqi Chemical Plant. Spraying can increase the leaf water content, enhance the water retention capacity, strengthen the photosynthetic intensity, weaken the respiration intensity. When dry and hot wind occurs, the wheat field sprayed with the petroleum extender can increase the leaf water content by 5-28% and reduce the leaf transpiration intensity 600-3,0002 mg / g / h, is conducive to the manufacture and accumulation of organic substances, so that plants grow robust and enhance the ability of anti-dry hot air. In 1975, 33.8 were sprayed in our area
