林木播种苗的播后管理工作是苗圃管理中的重要一环,特别是秋冬季播种苗,播后管理工作尤为重要。1、覆盖:是在播种地上用塑料薄膜、作物秸秆、腐殖质土加以覆盖,保温、保水、防风害、防冻害、防岛害等,减少浇水次数,有利于种子发芽,覆盖厚度视覆盖材料有所不同,作物秸秆以不露地面为宜,腐殖质土以2cm 为宜。对出苗期短、出芽率高、发芽容易的种子可不覆盖。覆盖后还要经常检查,防止覆盖物被风吹走。当幼苗木量出土时,要将作物秸秆及时撤除。2、灌水:种子播种后立即进行滴灌或喷灌,之后的灌水次数、灌水量,应结合气候、土壤、树种特性和覆盖材料综合
Post-sowing forest sowing management is an important part of nursery management, especially sowing seedlings in autumn and winter, after sowing management is particularly important. 1, Cover: It is to cover the plastic film, crop stalks and humus soil on the sowing ground with heat preservation, water retention, wind protection, frost damage prevention and island prevention, etc. to reduce the number of watering, which is good for seed germination, covering thickness as covering material Different, crop stalks to not reveal the ground is appropriate, humus soil to 2cm is appropriate. The seedling is short, high germination rate, easy to seed germination can not be covered. Always check after covering to prevent the covering from being blown away. When the amount of seedlings unearthed, the crop straw should be promptly removed. 2, irrigation: seeds immediately after drip irrigation or sprinkler irrigation, after the number of irrigation, irrigation, should be combined with climate, soil, tree species and comprehensive coverage of materials
