为了防止柳杉瘿瘤病的蔓延对天目山柳杉Cryptomeria fortunei健康的影响,采取了多种防治措施,其中之一就是输营养液.通过对柳杉新梢生长量、相对叶绿素含量、叶绿素荧光参数的测定以及对柳杉瘿瘤分布格局的调查,研究了输营养液对天目山柳杉的影响.结果表明:在3月到10月期间,输营养液柳杉的新梢相对生长量比对照的大5.7%;在8月输营养液柳杉的相对叶绿素含量值比对照的大3.7%,10月两者均迅速降低;8月输过营养液柳杉的光系统Ⅱ光量子效率(F_v/F_m)值是对照柳杉的1.29倍;目前试验柳杉枝的瘿瘤以直径1～3 cm的中瘿瘤最多,直径<1 cm和直径>6 cm的瘿瘤分布很少.输营养液在一定程度能改善天目山柳杉健康状况.图5表2参11

Various measures have been taken to prevent the spread of the tumor disease of Cryptomeria fortunei on Mount Tianmu. and transfusion of nutrient solution is one of them. This paper studied the effects of transfusion of nutrient solution to C. fortunei by measuring the fresh treetop growth, the relative chlorophyll content, the chlorophyll fluorescence parameters and by surveying the tumor distribution pattern. The results showed that from March to October, the relative fresh treetop growth of C. fortunei with nutrient solution was larger than the control by 5. 7 per cent. In August SPAD value of the C fortunei with nutrient solution was larger than the control by 3. 7 per cent, and both of them reduced quickly in October. In August the F_v/F_m of the C fortunei with nutrient solution was 1. 29 times as much as that of the control. At prescnt. the diameters of most C. fortunei tumors were between 1-3 cm and few were less than 1 cm or larger than 6 cm. The transfusion of nutrient solution has improved the health of the C fortunei on Mount Tianmu to some extent. [Ch, 5 fig. 2 tab. 11 ref. ]
