近年来随着花木市场的发展,菊花优良品种不断出现,笔者根据教学的需要,对菊花的优良品种进行越冬留种及管理的试验,效果很好,现就其方法介绍如下:一、母株脱盆地栽养护越冬1994年12月选出7盆适宜作切花的盆菊,将菊花连同盆土从盆中脱出,修去土坨周围的须根,穴栽于品种园内,栽植深度以盆土高度为宜,过深遇雨雪积水易引起冻害或烂根。剪去残花、枯枝、枯叶,减少养分的消耗,保留活枝和绿叶,进行光合作用,使植株体内最大限度地积蓄养分。雨雪或大风天气,需覆盖干草保温。二、春季的管理1.水肥管理开春后,菊花从母株的根和茎上陆续发出脚芽或茎芽,此时剪去母株老茎,这段时期因母株老根逐渐失去吸收能力, In recent years, with the development of flowers and trees market, chrysanthemum varieties continue to emerge, the author according to the needs of teaching, chrysanthemum varieties for winter maintenance and management of the test, the effect is good, the method is described below: First, From 1994 to December 1994, 7 pots of potted chrysanthemum suitable for cut flowers were selected, and the chrysanthemums were removed from the pots together with the potting soil. The fibrous roots around the potatoes were planted in the garden. Height is appropriate, too deep rain and snow water easily cause frost damage or rotten roots. Cut the residual flowers, dead branches, dead leaves, reduce nutrient consumption, keep live branches and green leaves, photosynthesis, so that the maximum accumulation of nutrients in plants. Rain or windy weather, need to cover the hay insulation. Second, the spring management 1. Water and fertilizer management After the spring, the chrysanthemum roots and stems from the mother plant one after another issued foot buds or stem buds, this time cut off the mother plant old stems, this period due to the mother plant roots gradually lose absorption capacity ,
