连茬栽培对人工营养土理化性质及番茄产量的影响

通过利用当地的玉米秸秆为主要材料与土壤、草炭分别按不同的比例配制的人工营养土与土壤做比较,通过物理化学的方法检测所配人工营养土的营养成分、物理化学特性的好坏,并在日光温室内对番茄进行试验,研究所配制的人工营养土对番茄的生长发育、产量和各种品质的影响。研究结果表明,人工营养土栽培可以在很大程度上改善番茄植株的产量。在本试验所做的四个处理中,处理B:土:玉米秸秆=1:2+鸡粪(15kgm-3)和处理D:草炭:玉米秸秆=1:2+鸡粪(15kgm-3)的处理效果较好,考虑到经济和节省资源等因素,建议在生产中应用处理B:土:玉米秸秆=1:2+鸡粪(15kgm-3)。

Effects of Artificial Compositive Soil in Continuous Culture on Physical and Chemical Characteristic and Yield on Tomato

Compared with only soil, effect of artificial compositive soil on tomato growth, output and each kind of quality were researched in greenhouse, by using local maize straw as the main material, soil and peat under different preparation, and nutrition ingredient, physical and chemical characteristics were also tested. Results showed that artificial compositive soil could improve physiological index of tomato, such as yield. Among the four treatments, treatment B: (soil: straw =1∶2) and chicken manure 15kg m-3 and treatment D(peat: straw=1∶2) and chicken manure 15kg m-3 were better. Considering factors as economy and saving resources, treatment B(soil: straw =1∶2) and chicken manure 15kg m-3 was advised for producing.
