- 摘要:
- 针对拉萨市设施番茄土壤连作障碍,通过盆栽试验,在番茄连作土壤中添加4种不同的微生物菌肥,研究微生物菌肥(F1,绿士达根病专家0.1 g·盆-1;F2,生绿土菌净0.08 g·盆-1;F3,阿瑞斯0.1 g·盆-1;F4,微朵复合微生物菌剂0.1 g·盆-1;CK1,温室附近露地土壤;CK2,连作土壤)处理土壤对番茄不同时期的生长及其叶片防御性酶活性的影响。结果表明:4种微生物菌肥均能不同程度促进连作番茄的生长,其中F1处理番茄的株高、茎粗、植株总干质量及叶面积均较CK1和CK2显著增加。POD、PPO、PAL活性均呈现先增后降的趋势,番茄开花坐果期Ⅰ时F2处理的POD活性达到最大值,POD活性分别比CK1增加66.1%,比CK2增加77.6%,F3处理的PPO活性达到最大值,PPO活性分别比CK1增加47.7%,比CK2增加40.4%。番茄幼苗期Ⅱ时F3处理的PAL活性在达到最大值,F3处理的PAL活性分别比CK1增加67.4%,比CK2增加59.8%。总体来看,4种微生物菌肥均能不同程度的提升番茄抗性酶的活性。
- Abstract:
- Aiming at the soil continuous cropping obstacle of greenhouse tomato in Lhasa,pot experiments were conducted,adding 4 different microbial fertilizer on tomato continuous cropping soil,treatment effect of soil microbial fertilizer(F1,Lyushida root disease expert 0.1 g·pot-1;F2,Shenglyu soil bacteria clean 0.08 g·pot-1;F3,Aruisi 0.1 g·pot-1;F4,Weiduo compound microbial fertilizer 0.1 g·pot-1;CK1,uncovered soil near greenhouse;CK2,continuous cropping soil)on tomato in different periods of growth and defensive enzyme activity in tomato leaves were studied.The results showed that,4 kinds of microbial fertilizer could promote the growth of tomato continuous cropping in different degrees,the plant height,stem diameter,plant dry weight,leaf area of tomato treated with F1 were significantly higher than those of CK1 and CK2.The activities of POD,PPO and PAL increased first and then decreased,the POD activity of F2 treatment reached maximum at flowering and fruitⅠ,POD activity increased by 66.1% compared with CK1,and increased by 77.6% compared with CK2,the PPO activity of F3 reached maximum,PPO activity increased by 47.7% compared with CK1,and increased by 40.4% compared with CK2.The PAL activity of F3 treatment reached the maximum at the seedling stage II,the PAL activity of F3 treatment was 67.4% higher than that of CK1 and 59.8% higher than that of CK2.Overall,4 kinds of microbial fertilizer can enhance tomato resistance enzyme activity to varying degrees.
