一.引言我国小麦的主要产区,绝大部份为旱地,经常遭受乾旱的威脅,因此如何从生理上去加强小麦的抗旱能力,实为急待研究的问题之一。根据苏联金傑里教授的研究,在种子萌动的初期,予以適当的播种前乾旱锻鍊可以使以後的植株代谢强度增加、原生质的弹性、粘性和束缚水量提高,因而它们的抗热和抗脱水能力也都加强、在不太长期的乾旱年份里、锻鍊小麦可比对照增产15—175％,这种锻鍊方法,目下在苏联農业生产上已有试用。在我国近年来也有一些用小麦进行乾旱锻鍊的试验,但结果未能一致,植物生理研究所用
I. INTRODUCTION The main producing areas of wheat in our country are mostly dry land and are often threatened by drought. Therefore, how to strengthen the drought-resistant ability of wheat physiologically is one of the most urgent problems to be studied. According to the study of Professor Kim Jerry of the Soviet Union, proper early planting of drought forging can increase the metabolic intensity of plants after the seed germinating, and increase the elasticity, viscosity and bound water of protoplasm so that their resistance to heat and dehydration In the less prolonged drought year, forged wheat production could be 15-175% more than in the control. This method of forging is now under trial in the agricultural production of the Soviet Union. In our country, there have also been some experiments of using wheat forging forging in recent years, but the results have not been consistent. In plant physiology research
