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(Streptomyces pseudovenezuelae)、肉质链霉菌(Streptomyces carnosus)、密旋链霉菌(Streptomyces pactum)、1株未定种的链霉菌(Streptomyces sp.)、球孢链霉菌(Streptomyces globisporus)等质量混合]和放线菌剂B[肉质链霉菌(Streptomyces carnosus)、密旋链霉菌(Streptomyces pactum)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.1was chosen as materials to study the effect of two application patterns,irrigating root and mixing with soil,with actinomyces A(Streptomyces californianus∶Streptomyces pseudovenezuelae∶Streptomyces carnosus∶Streptomyces pactum∶Streptomyces sp.:Streptomyces globisporus=1∶1∶1∶1∶1∶1(mass mixing ratios))and actinomyces B(Streptomyces carnosus∶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.
