夏季是玫瑰的盛花期,此时利用未着花的封顶枝配合其他措施进行绿枝扦插,成活率较高。具体做法是:培育插穗玫瑰随着株龄增长,其生活率也随之下降。专家试验表明.用玫瑰老枝作捅穗,发根希望十分渺茫。如何获得更多的封顶枝呢?可以这样做:冬季轻剪,促其在次年春季萌发更多的新枝,对徒长枝进行短截。控水肥,由于新枝多,一旦水肥供不上,当枝条伸长到10～30厘米时就封顶停止伸长(见图)。少给光照,每天只给2～4个小时光照,植株则开花稀疏、封顶枝多(图1,一根老枝萌发13根新枝,
Summer is the flowering of roses, at this time the use of uncapped capping branches with other measures for green branch cutting, higher survival rate. The specific approach is: to cultivate cut rose as the growing age, its life rate also will decline. Expert tests show that with the old branch of roses as a poke spike, hair roots hope is slim. How to get more capped branches? You can do: lightly cut in winter, prompting more new branches in the spring of next year, stubby branches. Control of water fertilizer, due to the new branches, once the water and fertilizer can not, when the branches extended to 10 to 30 cm when the cap to stop elongation (see photo). Less light, only 2 to 4 hours a day light, plants are flowering sparse, capped more branches (Figure 1, an old branch of 13 new branches germination,
