摘要
播前干旱锻炼是抗旱增产的措施之一。本文根据有关资料及笔者的工作,分析了有关锻炼方法的关键因素及其对植物抗旱性的影响和生理基础。种子干旱锻炼能够提高植物在土壤干旱条件下的萌发成苗能力,对干旱地区抢播保苗有一定的意义。锻炼是否增加经济产量,只有在严格控制环境因素的条件下测定产量,并进一步搞清有关生理机制,才能得出正确结论。
Pre-sowing drought hardening is one of physiological measures to improve drought-resistance and raise crop yields.Based on research results, this paper analyses some key factors of the pre-hardening, effects of this technique on plant growth and its physiological bases.It is considered that the hardening trcatment is of great importance in improving plant germination and seedling survival as well as rush planting in the arid areas.As to whether it can increase yield or not, only by strictly controlling environmens under which crop yields are deteimined, can the correct conclusions concerning physiciological mechanims be obtained.
