关于现代月季(Rosa hybrida Hort.)在营养诊断和施肥方面,国外曾有零星报道。为了了解大量营养元素及水分在不同生长阶段的含量分布及趋向,本试验对几个现代月季品种在不同生长阶段其植株内的大量营养元素氮(N)、磷(P)、钾(K)、钙(Ca)、镁(Mg)及水分含量作了分析测定。 材料与方法 一,材料 选用当前较流行的三个现代月季切花品种: 1.超级明星( SuperStar);2.荷兰粉红( Holland Pink) ;3.基督教徒( Christian Dior)。 二、采样方法 根据南方气候特点,月季在当年9月至翌年5月为生长适期,本试验采样时间为1986年12月,随机切取健康芽接苗之地上部分在不同生长时期的全部组织。各生长阶段如下:1.营养生长阶段:(1)初期(2)旺期2.生殖生长阶段:(1)见蕾期(2)花蕾增粗期(3)花朵开放期3.谢花后期。
About Rosa hybrida Hort. There have been sporadic reports abroad on nutrition diagnosis and fertilization. In order to understand the content distribution and trend of macronutrients and water in different growth stages, the effects of nitrogen (N), phosphorus (P) and potassium (K) in the plants of several modern rose cultivars at different growth stages were studied. , Calcium (Ca), magnesium (Mg) and moisture content were analyzed and determined. Materials and methods First, the material selection The more popular three varieties of modern rose cut: 1. SuperStar (SuperStar); 2. Holland Pink (Holland Pink); 3. Christian (Christian Dior). Second, the sampling method According to the characteristics of the southern climate, the rose in September of the following year to May next year for the growth period, the test sampling time in December 1986, randomly cut the buds of healthy buds at all parts of the growth of all tissues. The growth stages are as follows: 1. Vegetative growth stage: (1) initial stage (2) Wang period 2. Reproductive growth stage: (1) see the bud stage (2) bud thickening period (3) .
