摘要:
研究了不同耕作方式棉花根系的发育能力。结果表明，根系生物量、根系体积、侧根数在不同耕作方式间差异明显，在土壤中表现为从表层到深层逐渐递减。免耕方式根系分布较浅，主要集中在0~10 cm土层，而翻耕方式根系主要分布在10~20 cm土层。侧根的发生部位受不同深度土壤含水量的影响，侧根发生的主要部位在0~20 cm的主根段，40 cm以下没有侧根发生。
Abstract:
The root system development ability of cotton with different cultivation way is analyzed.The results show that there are difference among different cultivation way in root system biomass,root system volume and the number of secondary root.Vertical distribution of root system biomass,volume and secondary root are decreased from 0~10 cm depth to 40~50 cm depth.The root system of zero tillage distribute relatively shallow,mainly concentrate on 0~10 cm soil layer,while the root system of plowing are mainly distribute on 10~20 cm soil layer.Secondary root is affected by soil water content in different depth.The secondary roots of cotton grow mainly from the taproot underground 0~20 cm depth,and there are no secondary roots below 40 cm depth.
