摘要
In order to study the effects of different fertilizers on the growth and yield of Moringa seedlings,potted Moringa seedlings were randomly divided into 5 treatments:nitrogen(treatment 1),phosphorus(treatment 2),potassium(treatment 3),compound fertilizer(treatment 4)and non-fertilization(CK).The ground diameter,plant height,leaf,sprouting,crown width and yield of Moringa seedlings were measured one month later.The results showed that treatment 3 was beneficial to the growth of ground diameter of Moringa seedlings,which was 24.4%higher than CK(P<0.05).Treatment 4 significantly promoted plant height and leaf yield of moringa seedlings,being 56.8%and 76.9%higher than those of CK,respectively(P<0.05).Treatment 2 significantly promoted the sprouting of Moringa seedlings,being 53.8%higher than that of CK(P<0.05).Fertilization treatments had no significant effect on leaf size of Moringa seedlings(P>0.05).
为了研究不同肥料对辣木幼苗生长和产量的影响,盆栽辣木幼苗,采用随机区组试验,设置氮(处理1)、磷(处理2)、钾(处理3)、复合肥(处理4)和不施肥(CK)5个处理,1个月后测定辣木幼苗地径、株高、叶片、抽芽、冠幅和产量等生长指标。结果表明:处理3有利于辣木幼苗地径的增长,比CK高24.4%(P<0.05);处理4对辣木幼苗株高和枝叶产量有显著的促进作用,分别比CK高56.8%和76.9%,(P<0.05);处理2对辣木幼苗抽芽有显著促进作用,比CK高53.8%(P<0.05);各施肥处理对辣木幼苗叶片大小没有显著影响(P>0.05)。
