一、当前苗木生产、供求特点(一)苗木生产滞后,无计划生产,盲目性较大。从事苗木生产,季节性较强,又需要较长的生产周期,既不能向工业产品那样,需要时加班、加点组织生产,不需要时可以储存;也不同于短周期的农作物生产,不同树种苗木的生产周期长短不一,短生产周期的树种需要2～3年,长生产周期的树种需要5～8年以上。所以,苗木如果根据造林绿化工程做到按时供应,至少需要提前3～5 First, the current production of seedlings, supply and demand characteristics (A) lag production of seedlings, no planned production, blindness. In the production of seedlings, seasonally strong, but also the need for a longer production cycle, neither to industrial products, as needed overtime, add some production, when not required can be stored; also different from the short cycle of crop production, different tree seedlings The production cycle of different lengths, short production cycle tree species need 2 to 3 years, long production cycle tree species need 5 to 8 years. Therefore, seedlings if afforestation projects according to timely supply, at least 3-5 days in advance
