摘要:
通过对昭苏马场春秋草场不同围封年限草地主要种群分布格局的研究,结果表明:围封草地自然恢复过程中,种群分布格局相对稳定.除草原糙苏和黄花苜蓿表现为随机分布外,其它种群均为集群分布.大部分种群聚集强度的变化趋势是先减小后增大,未围封草地的聚集强度最大.
Abstract:
We used the good qualified species Yannong 475 of winter wheat as the study materials,and studied the influences of different irrigation amounts and stages on the water consumption characteristics,physiological characteristics,grain yields and water use efficiency of winter wheat.The results show that excessive and insufficient soil water content would both have affected the grain yields and water use efficiency of winter wheat.And different irrigation stages would also influence the grain yields.In addition,the irrigation treatment W4 has the highest grain yield and higher water use efficiency which shows that W4 treatment is the best irrigation method with higher yields and lower water consumption.
