施肥对美国杏李生长的影响

Effects of Fertilization on the Growth of Prunus simonii

以美国杏李(味厚、味帝2个品种)为试验材料,采用随机区组,设3个重复,定期分别等量每株施用N 5 g+复合肥10 g、N 10 g+复合肥10 g、N 15 g+复合肥10 g,并设对照,观测美国杏李生长状况,分析研究不同施肥处理对美国杏李地径、株高、苗冠生长的影响。结果表明,施肥处理2(N10 g+复合肥10 g)对美国杏李的苗木地径影响最大;施肥处理1(N 5 g+复合肥10 g)对苗木株高影响较大;各施肥处理对苗木的苗冠影响不显著。

This paper observed the growth situation of Prunus simonii and studied the effects of different fertilizer treatments on ground diameter, height and crown based on the check experiment for two varieties of Weidi and Weihou which were randomly grouped and set 3 repetitions regularly dealing with 10g of N5 g ＋ compound fertilizer , 10g of N10 g ＋ compound fertilizer and 10g of N15 g ＋ compound fertilizer respectively. The results showed that the effect of 10g of N10 g ＋ compound fertilizer on the seedling di- ameter was greatest, the effect of 10g of N15 g ＋ compound fertilizer on the seedling height was relatively great and the effects of all fertilization on seedling crown were not significant.
