摘  要:
通过桶栽试验,研究了地膜和秸秆2种覆盖方式对梨枣树生长的影响。结果表明,覆盖处理提高了桶内的土壤含水率,其中地膜覆盖的保水效应更为明显。受温度及果树自身生长的影响,保水效应在萌芽展叶期更显著。覆盖处理有明显的促进梨枣树生长的作用,新梢和枣吊等指标生长量大,且持续生长时间长,以地膜覆盖最为显著。不同处理对叶绿素相对质量分数影响较大,3个处理的叶绿素相对质量分数均呈增大趋势,其中秸秆覆盖在2个生育期中增量最大,达到了16.5%。

摘  要:
Through the barrel planted test,the effects of plastic and straw mulching on pear-jujube tree growth was studied.The results show that mulching treatments increase the soil moisture content,and the water-saving effect of plastic mulching was more obvious.Influenced by the temperature and the fruit trees' own grow,the water-saving effect in sprouting-leaf unfolding stage was obvious.The treatments of mulching can promote fruit trees growth,the volume of new shoot and panicle growth was more,continuous growth time was longer,the plastic mulching was the most significant.Effect of different treatments on SPAD value was huge,the three treatments SPAD value all presented trend of increase.During the two growth periods,the straw mulching's increase value was the most,reached 16.5%.
