落叶松苗属于喜肥类型。在培育过程中施肥合理与否,直接影响苗木的质量、数量及经济效益的大小。而施肥又受土壤和气候条件的影响,尽管各地土壤气候条件各异,但有些基本规律和经济法则,在育苗过程中还是可以遵循和利用的。为了确定施肥合理而经济效益最大的施肥置,我们对培育落叶松苗进行了初步的研究。一、试验地概况本试验是在吉林市松花江苗圃进行的。土壤类型为淋黑或无石灰性冲积土。土名为黑砂土,质地砂壤土。土壤分析如表1。 Larix seedlings belong to the type of hi fat. Fertilization in the cultivation process is reasonable or not, directly affect the quality of seedlings, the number and size of economic benefits. Fertilization, in turn, is affected by soil and climatic conditions. Although soil and climatic conditions vary from place to place, some basic rules and economic laws can be followed and utilized in the process of nursery. In order to determine fertilization reasonable and most economic fertilizer home, we conducted a preliminary study of the cultivation of larch seedlings. First, the test site Overview This experiment is carried out in Jilin Songhuajiang nursery. Soil type is black or non-calcareous alluvial soil. Soil called black sand, texture sandy loam. Soil analysis is shown in Table 1.
