适时灌水:采穗圃里要设置排灌沟渠,使之旱能灌涝能排。第一年苗木灌水8～10次,头遍水要灌饱,2～3遍水浅灌少灌,6、7、8月要灌足,苗木生长后期停止灌水。第二年灌水次数减少为5～6次,每次灌水量适当增加。 松上除草:扦插或栽植初期,采取浅松土,深度3～5厘米,同时除草。6月中下旬以后,根系已木质化,降雨和灌溉易造成土壤板结,杂草滋生,所以要深松土勤除草,松土深度6～8厘米。全年需松土
Timely irrigation: Excavated nursery irrigation and drainage channels to be set to make irrigation drought can row. The first year of seedlings irrigation 8 to 10 times, head to full irrigation, 2 to 3 times shallow irrigation less irrigation, 6,7,8 months to fill foot, seedling growth late stop irrigation. The second year the number of irrigation reduced to 5 to 6 times, each time the amount of irrigation increased. Loose weeding: cutting or planting early, take shallow loose soil, depth 3 ~ 5 cm, while weeding. After the middle and late June, the roots have been lignified. Rainfall and irrigation can easily lead to soil compaction and weeds breeding. Therefore, soil should be subsoiled and ground weeded with weeds to a depth of 6 to 8 cm. Loose soil throughout the year
