侧柏春播育苗常因春旱、涝而影响适时播种或推迟发芽期;五、六月间幼苗弱小,根系柔嫩,此时正逢杂草旺季,除草工作繁重;苗木生长发育期短,质量不好,往往当年不能上山造林。笔者实践证明,利用侧柏种子没有休眠期的特点,在种子成熟时随采随播,是解决上述问题的切实可行办法。现将具体做法介绍如下: 淮北和沿淮地区9月中旬侧柏种子自然成熟,抓紧时间在20年左右的优良母树上采种,经水选捞出种子晾干,即可播种。苗床应施足基肥,土碎床平,顺床开沟,用喷壶顺床沟浇
Arborvitae spring nursery often due to spring drought, waterlogging and timely sowing or postpone the germination period; May and June the seedling is weak, tender roots, at this time is the weed season, heavy weeding; seedlings growth and development is short, the quality is not Well, often can not go up the mountain reforestation. The author has proved that the use of Platycladus orientalis seeds without dormancy characteristics, with the seed sowing at maturity, is a practical solution to the above problems. Here are the specific practices are as follows: Huaibei and Huaihe area in mid-September Platycodon grandiflorum seeds mature naturally, seize the time in about 20 years of planting on the fine mother trees, the water pick out the seeds to dry, you can sow. Seedbed should be applied enough base fertilizer, soil crushed bed flat, cis bed ditch, with watering can Shun bed bed ditch
