盆景树种雀梅,多年来北方地区大都是从江浙以南引入的,尚无自己繁殖培育的先例。我于1990年开始采种繁殖小苗,并加工制作成小型盆景,长势十分喜人。现将试验情况介绍如下: 一、种子采集:我园所养殖的50株雀梅盆景,是1982年从浙江引进的,近十年来几乎没有结籽。经分析,主要原因是多年来只注重施氮肥,很少施用磷、钾肥;雀梅为阳性植物,多年来一直在荫棚内养护,光照条件不足,故难以开花结果。原因找到后,我采取这样一些措施:在春天雀梅未萌芽前翻盆,加入适量的蹄片和腐熟的麻渣;7月份,将雀梅从荫棚内移至全日照下,同时进行一次修剪,加强肥水管 Bonsai tree bird plum, most of the northern region was introduced from Jiangsu and Zhejiang over the years, there is no precedent for their own breeding. I began breeding breeding seedlings in 1990, and processed into small bonsai, the growth is very gratifying. Now the test conditions are as follows: First, the seed collection: I park breeding bird pie bonsai 50 plants, imported from Zhejiang in 1982, almost no seed in the past decade. After analysis, the main reason is that only nitrogen fertilizer has been paid attention to over the years and phosphorus and potassium fertilizer have been seldom applied. Birdfinches are positive plants and have been conserved for years in shade sheds. When the reason was found, I took some measures like this: In the spring, the sparrows did not sprout, turn over the basins, add the proper amount of shoddy pieces and the matured marsh. In July, the sparrows were moved from the shade to the whole sunshine and at the same time Trim, strengthen the fertilizer pipe
