旱地小麦休闲期耕作+播种方式对幼苗的影响
Effect of Tillage Supported Sowing Method in Leisure Period on Seedling Growth Characteristics of Dryland Wheat
摘要
Abstract
This paper studied the effect of tillage supported sowing method in leisure period on soil water storage at the depth 0 — 60 cm, dry weight in plant, root activity and resistance index in wintering of dryland wheat. The results showed that subsoiling can improve soil water storage at the depth 0~60 cm, dry weight in plant, root activity and soluble sugar content, and reduce POD, SOD activity of leaves. The results also indicated that soil water storage at the depth 0—-60 cm and dry weight in plant were highest under full—film casing bunch; root activity was highest under membrane side of the drill; soluble sugar content, the activity of POD and SOD were lowest under full—film casing bunch, and the difference was significant from other treatments. So, the cultivation practices of subsoiling supported full — film casing bunch in leisure period helped to improve soil water storage capacity, and promoted the growth of dryland wheat. This research can provide a clue to soil water storage in leisure period of dryland wheat.关键词
