青海浅山地区不同土壤含水量对春小麦出苗的影响

Effects of Different Soil Water Content on Spring Wheat Emergence in Shallow Mountain Region Qinghai

利用盆栽种植的方式,人为控制土壤含水量观测对春小麦出苗的影响,其结果表明:春小麦出苗的土壤最低含水量为12%,12%土壤含水量比13%-14%含水量出苗期晚10-12d,13%-14%土壤含水量春小麦出苗快,苗整齐健壮,土壤含水量10%-11%,春小麦种子吸水困难,不能正常出苗。

By planting in pots to control soil content artificial to observe the effects on spring wheat emergence ,the results showed minimum water content for emergence was 12%,the time of emergence （12%） was later 12-13d than that of water content was 13%-14%,seeds germination were quick,being even and strong while water content was 13%-14%,when water content was 10%-11%,seeds were difficult to absorb moisture ,so they could not emergence normal.
