摘要
以三年生沙地柏移植苗为材料,采用对比试验方法,于缓苗期、生长初期、速生前期、速生后期分别对土壤进行不同施肥处理,测定苗木各项生长指标,研究了不同施肥对沙地柏苗木生长的影响。结果表明,施用多元素复合肥对促进叶绿素的合成,加速苗木生长影响较大;施用N、P、K肥与多元素复合肥对苗木生物量积累影响较大。
Taking three Sabina vulgaris＇ transplant seedlings as the material, uses the contrast test , through doing diverse fertilization treatments at different times of the suspend stage of seedling , the initial stage, the early stage of rapid growth and the later stage of rapid growth on Sabina vulgaris＇ transplant seedlings, the paper studied the Effect of diverse fertilization on the Growth of Sabina Vulgaria Seedlings by measuring seedlings＇ every growth index. The results show that it has more effect for seedlings＇ high growth, chlorophyll content through using many element composite fertilization at different times; It has more effect for seedlings＇ biomass through using N, P, K fertilization and many element composite fertilization at different times.
