以珍贵树种土沉香(Aquilaria sinensis)1.5年生幼苗为材料进行试验,设定了4种不同施肥措施,即对照(ck)、复合肥N1、叶面肥N2和根肥N3,研究不同施肥处理对土沉香苗期土壤环境肥力变化的影响。结果表明,不同施肥处理土壤水分、温度和电导率在不同时期变化不一致。土壤养分在不同月份及不同处理间变化情况不同,土壤铵态氮N1处理时最高,土壤速效磷均在施肥处理时显著高于ck,土壤速效钾在施肥1个月时低于ck,3个月时,叶面肥处理(N2)土壤速效钾含量有所提高,其余施肥处理仍显著低于ck。
The experiment was conducted on 1.5-year-old seedlings of Aquilaria sinensis, and four different fertilization measures were set up, ie CK, N1, S2 and N3. The effects of different fertilization treatments Influence of soil seedling ’s soil environment and fertility on seedling radix. The results showed that soil moisture, temperature and conductivity of different fertilization treatments changed inconsistently at different periods. The changes of soil nutrients in different months and in different treatments were different. Soil ammonium nitrogen N1 was the highest, soil available phosphorus was significantly higher than ck when applied fertilization, soil available potassium was lower than ck and 3 Month, foliar fertilizer (N2) soil available K content increased, the rest of the fertilization is still significantly lower than the ck.
