| The objective of this work is to elucidate the influence of straw bioreactor on the growth characteristics of greenhouse tomato in autumn and winter, such as plant morphology, photosynthesis, fruit quality, and yield. Results showed the application of straw bioreactor effectively promoted
the growth of tomato plants, and increased plant height and stem thickness by 8% and 10%, and improved the contents of protein, soluble sugar, Vc, and organic acid by 11%, 17%, 14%, and 12%, as compared with control area. It was suitable for the photosynthesis of the plant and the accumulation of dry matters as soil moisture was maintained at 60%～70% of θf. It is suggested that the minimum limit of soil moisture is at 60%～70% of θf at seedling stage, at 70%～80% at flowering and fruit-setting stage, and at 70%～80% at fruiting stage of tomato growing in winter under drip irrigation. In addition, application of straw bioreactor should be of value for improving yield, quality, and economic benefit of tomato production. |
