马尾松幼林施肥持续8年的生长效应
Study on Consecutive 8 year Effect of Fertilizer to Juvenile Masson Pine Plantation
【摘要】 1992~ 1999年在福建省邵武市花岗岩发育的低丘红壤上 ,对马尾松幼林施肥进行了持续 8年的观测研究。结果表明 :在第 8年时 ,无论是施 P还是其它肥料 ,其对总生长量或连年生长量的增长效应已不显著 ;单施钙镁磷肥或再配合尿素、氯化钾肥料的效应至少可以持续到第 6年 ,至第 7年仍维持一定的增长效应 ;而单施尿素、氯化钾肥料的效应一直均无明显表现
【Abstract】 The research into consecutive 8 year effect of fertilizer to juvenile masson pine ( Pinus massoniana ) plantation was conducted in hilly red soil derived from granite at Shaowu City of Fujian Province from 1992 to 1999. The results show that there is no significant effect both for P (calsium magnesium phosphate) and other fertilizers to total growth or average annual growth in young masson pine plantation at the eighth year after treatment. The effect of P lonely or its mixture with N (urea) and K (potassium chloride) could be observed at least until the sixth year and the seventh year to some extent.And single urea treatment or potassium chloride did not significantly influence the growth.
