摘要
过龙缸栽培圆柏试验,研究A(田园土)、B、C、D、E、F、G、H、I(B、C、D、E、F、G、H、I分别为用田园土、河沙、鸡粪、玉米芯和花生壳按不同体积比混合组成)等9种不同基质对圆柏树径和顶端分枝数、以及叶绿素、丙二醛(malonaldehyde,MDA)、脯氨酸和可溶性糖含量的影响。结果表明:8种加入不同比例农业废弃物混合栽培基质的圆柏树径增长率、顶端第一分枝数、顶端第二分枝数、顶端第三分枝数及叶绿素、可溶性糖和脯氨酸含量等指标各不相同,但均高于A基质(田园土);MDA含量也各不相同,而均低于A基质(田园土)。聚类分析显示,9种栽培基质大致可分3类:最适宜圆柏生长的基质为H、G、F;中等适宜的为I、E、D;最差的为C、B、A。隶属函数法评价显示,9种基质中栽培的圆柏生长状况由强到弱依次为H、G、F、I、E、D、C、B、A。因此,上述9种基质中以田园土、河沙、鸡粪、玉米芯和花生壳按1.0∶0∶0.5∶1.5∶1.5∶1.5比例混合的栽培基质(H)最适宜圆柏生长,其次为G、F基质,再其次为I、E、D、C、B基质,田园土(A基质)效果最差。
Sabina chinensis was transplanted in earthen pots with drainage hole to examine the effect of A（field soil）, B, C,D, E, F, G, H or I substrates（the cultivation substrates mixed with field soil, sand, chicken manure, corncob and peanut shell in the different proportions of volume） on the tree diameter, number of branches at the top, the contents of chlorophyll,malondialdehyde（MDA）, proline（Pro） and soluble sugar. Results showed that the growth rates of tree diameter, the number of branches at the top（including the first branch, the second branch, third branch）, the contents of chlorophyll, pro and soluble sugar of S. chinensis cultured with B, C, D, E, F, G, H or I substrates mixed with agricultural waste in varying proportions were diverse from each other, while the values of these parameters were all higher than those of substrate A（field soil）. MDA contents were also different from each other, but they were lower than that of substrate A. Cluster analysis revealed that nine cultivation substrates were divided into three categories： the most suitable substrates for S. chinensis growth were H, G, F, the moderate substrates were I, E, D, and the worst were C, B, A. The evaluation by membership function method indicated that the growth status from strong to weak of S. chinensis cultivated with nine different substrates followed by H, G, F, I, E, D, C,B, A. Therefore, among nine different substrates, H mixed cultivation substrate in the proportion of 1.0 ∶0.5 ∶1.5 ∶1.5 ∶1.5 with field soil, cinders, river sand, chicken manure, corncob and peanut shell was the most suitable for S. chinensis growth,followed by substrate G and F, then followed by substrate I, E, D, C, B, and the worst was field soil.
