北京城市绿地中,草坪地被是绿化中不可缺少的重要组成部分,因此,种好草坪和做好草坪的防病工作对于绿化美化好城市环境都将起到重要作用。这里主要谈谈种子繁殖方法和草坪防病措施。一、草坪的种植与管理1.坪床的准备:播种前应对坪床进行深翻和土质改良。深翻深度至少为15-20厘米,若能达到30厘米以上更好。然后在表土15-20厘米层中拌施有机肥,以增加肥力,整地时地表最好做成中间稍高或单向倾斜的形式,以便于排水。2.播种:4月-9月播种均可,尤以早春和初秋最好。播种前,应测量坪床面积以确定播种量,实验证明,大粒种子在20克/平方米左右,中粒种子在15克/
In Beijing’s urban green space, the lawn is an indispensable part of greening. Therefore, planting good lawns and preventing diseases of lawns will play an important role in greening and beautifying the urban environment. Here mainly talk about seed breeding methods and lawn preventative measures. First, the lawn planting and management 1. Ping bed preparation: sowing should be carried out before sowing deep soil and soil improvement. Deep turning depth of at least 15-20 cm, if it can reach more than 30 cm better. Then in the topsoil 15-20 cm layers of organic fertilizer to mix, in order to increase fertility, land preparation is best made when the middle of the ground slightly higher or one-way tilt in order to facilitate drainage. 2. Seeding: April-September seeding can be, especially in early spring and early autumn is best. Before sowing, should be measured Ping bed area to determine the sowing, experiments show that large seeds in 20 g / square meters, medium-grain seeds in 15 g /
