不同抗旱类型冬小麦根系特征及其与产量的关系研究
Study on Root System Characteristic and Its Relationship with Yield of Winter Wheat Varieties with Different Types of Resistance to Drought
摘要
Abstract
Under the condition of natural rainfall , the author studied the root system characteristics and their relationships with the yield and yield components of 6 winter wheat varieties (lines) with different types of resistance to drought in Huang -Huai wheat area.The results showed that there was a significant difference in root system gross among different winter wheat varieties , the root number in various soil layers was different , and the root system was mainly distributed in 0~20 cm soil layer.As for the wheat varie-ties with strong drought-resistance and high yield, their root system dry weight was above average , and about 25% of total root sys-tem was distributed in the soil layer with the depth of above 20 cm.So the wheat varieties whose root system had too high (or too low) dry weight and was mainly distributed in 0~20 cm soil layer had relatively low grain yield in arid and semi -arid region.关键词
