近年来,我省各地本着“有灾抗灾、无灾增产、简便易行、就地取材”的原则,开展了用石油助长剂预防小麦干热风的试验研究。从我省多年的试验和我国北方11个省、市的试验情况来看,其作用是明显的。 干热风是发生在我国华北、西北等广大麦产区的主要灾害之一。我省鲁西南、鲁中地区小麦遭受干热风危害的频率最大。小麦受害后,麦芒外张而干枯,群众称为炸 In recent years, based on the principles of “disaster relief, disaster-free production increase, simple and convenient, and local use”, the pilot study on the prevention of wheat dry-hot wind with petroleum aids was carried out. From the years of experiments in our province and the experimental situation of 11 provinces and cities in northern China, its role is obvious. Dry and hot winds are one of the main disasters that occur in the vast wheat-growing areas in North China and Northwest China. Shandong Province, southwest of Shandong, Shandong Province wheat suffered the worst dry-hot wind frequency. After the wheat was damaged, the wheat was wiped out and the masses called it fried
