摘要:
通过田间调查,对不同施肥水平下紫花苜蓿(阿尔冈金)多叶性状的发生规律作了初步研究,结果表明单独施用不同水平的N、P、K对多叶株出现频率的影响没有显著差异,NPK三种肥料合理配施会显著增加多叶株出现频率。施氮肥能极显著影响苜蓿四、五叶型复叶出现的数目,每公顷施30KgN 和60KgN产生四、五叶型复叶的数目极显著的高于不施N肥的,并且具有随施氮水平的增加而增多的趋势。施用磷肥、钾肥对紫花苜蓿阿尔冈金的多叶数目没有影响。在整个调查范围内,以五叶型复叶数目最多,四叶次之,且远远大于六叶型,七叶型及七叶以上的复叶数目。
Abstract:
The relationship between the foliose character of alfalfa (Algonquin) and different levels of alimentation was primarily studied by field investigation. The results showed that applications of different levels of nitrogen,phosphorus and potassiun alone had no effect on the occurring frequency of multifoliolate alfalfa. The occurence of multifoliolate alfalfa increased when the three nutrients were applied integrategly. And the nitrogenous fertilizer significantly affected the number of fourleaved and fiveleaved alfafa. The number of different types of multifoliolate was: fiveleaved>fourleaved>sixleaved>seven or moreleaved alfalfa. The different levels of phosphorus and potassium had no effect on the number of multifoliolate. And the number of fiveleaved (fourleaved) was far higher than that number of other types.
