摘  要:
以"金鹏一号"番茄为试验材料,研究放线菌剂A[加州链霉菌( Streptomyces californianus ) 、假刺孢链霉菌(Streptomycespseudovenezuelae)、肉质链霉菌( Streptomyces carnosus )、密旋链霉菌(Streptomycespactum)、1株未定种的链霉菌(Streptomycessp.)、球孢链霉菌(Streptomycesglobisporus)等质量混合]和放线菌剂BL肉质链霉菌(Streptomycescarnosus)、密旋链霉菌(Streptomycespactum)等质量混合]按照灌根和拌土2种不同方式施入对连作番茄生长的影响.结果表明,2种放线菌均可促进番茄地上部、地下部和整株鲜质量的增加、根系活力的增长和叶绿素质量分数的提高,且随着生长时期的延长,菌剂效应有所降低,菌剂A采用灌根方式的促进作用最为明显.

摘  要:
Tomato cv. Jinpeng No. 1 was chosen as materials to study the effect of two application pat- terns, irrigating root and mixing with soil, with actinomyces A (Streptomyces californianus :Strep- tomyces pseudovenezuelae : Streptomyces carnosus ~ Streptomyces pactum : Streptomyces sp..Strep- tomyces globisporus=1:1 : 1 :1: 1 :l(mass mixing ratios) ) and actinomyces B (Streptomyces car- nosus : Streptomyces pactum = 1:1(mass mixing ratios)) on tomato growth. The results showed that, application of actinomyces A and B increased root fresh mass, shoot fresh mass and total fresh mass, and promoted root activity and chlorophyll mass fraction. The actinomyces effect decreased with tomato growth. Actinomyces A used in tomato root by irrigating had better effects to tomato growth.
