桧柏为常绿树种,树形高大优美,是城市庭园绿化的优良树种之一。桧柏育苗有播种、扦插两种方法,播种苗枝叶密茂,树冠丰满,树形更为美观。用播种苗的枝条作插穗,进行扦插育苗成活率也高。过去,我们繁殖桧柏时,把元月份采得的种子,沙藏至10月间进行冬播,2年生苗高仅12.2厘米,亩产苗木17262株。近年来随着城乡绿化事业的发展,桧柏苗木已供不应求。为了提高桧柏苗木的产量和质量,我们试用桧柏种子隔年沙藏春播育苗,获得了良好效果。10月间调查,当年生苗平均高21.6厘米,亩产量达20705株,每亩提高经济效益688元。我们采用的方法如下:1.种子处理:元月采种后,揉搓果实,阴干,除去果皮即得净种。对取得的净
Cypress cypress is an evergreen species, tall and beautiful tree, is one of the fine tree species of urban garden. Cypress nursery sowing, cutting two methods, sowing seedlings leaf Mimaru, full crown, the tree is more beautiful. Sowing sowing branches for cuttings, cutting seedling survival rate is also high. In the past, when we breed juniper cypress, the seed we collected from January of the same month in the sand bank was winter sowed in October. The 2-year-old seedling height was only 12.2 cm, and 17,262 mu of seedlings per mu were produced. In recent years, with the development of urban and rural greening, cypress cypress seedlings have been in short supply. In order to improve the yield and quality of cypress cypress seedlings, we try cypress cypress seedlings next year, spring sowing seedlings, obtained good results. Survey in October, when the average annual height of 21.6 cm seedlings, per mu yield of 20,705 plants, 688 yuan per acre to improve economic efficiency. We use the following methods: 1 seed treatment: January harvest, rub the fruit, dried, remove the peel that was net. Net gain
