摘 要:本试验以冬小麦泰农18为试验材料,以齐河县为试验地点,对小麦生长环境和生长生理进行了研究。结果表明:试验区内大部分土壤质地为壤土,且均呈碱性;随着土层加深,有机质和全氮含量均呈现先降低后增加的趋势;速效磷和速效钾含量均在表层土壤处含量最大,电导率呈现先升高后降低最后略有升高的趋势;最高气温为23.78℃;最低相对湿度为21.33%;泰农18整个生育期共计228 d,大约在播种后的160 d左右分蘖达到高峰;株高前期增长较快,后期缓慢,最高达到75.38 cm;叶绿素含量在抽穗期达到最大。In this experiment,Tanong 18 winter wheat was used as test material,and taking Qihe County as the test site,the growth environment and growth physiology of wheat were studied.It shows that most of the soils in the test area were loam and alkaline.With the deepening of soil layer,the contents of organic matter and total nitrogen decreased first and then increased.The contents of available P and available K were the highest in the surface soil,and the conductivity showed a trend of first increasing,then decreasing and finally slightly increasing.The highest temperature is 23.78℃;The lowest relative humidity was 21.33%.The total growth period of Tainong 18 was 228 days,and the tillering stage reached its peak about 160 days after sowing.The plant height increased rapidly in early stage and slowly in late,reaching 75.38 cm at the highest.Chlorophyll content reaches its maximum at heading stage.
