| 英文简介 | dSouth Xinjiang has dry climate and large evaporation and little rainfall which is belonging to the extreme arid area of inland. Irrigate by surface irrigation manner is easy to cause the soil salinity accumulation in facility because the strong evaporation in soil surface and water loss quickly, at the same time, the water holding capacity of desert soil characteristics is so poor that result in a reduced of soil moisture availability, on the basis of South Xinjiang special climate and soil conditions, this project introduces the technique of moistube-irrigation in low pressure which is appropriate to the irrigation facilities of South Xinjiang, and Start from the hydraulic properties of moistube-irrigation in low pressure, irrigation technique index, water consumption character of protected cultivated tomato, water use efficiency, physiological characteristics and quality, study on the relationship between the pressure head, flow and soil water potential, effects of soil parameters on soil water infiltration and wetting front transport properties, evapotranspiration and water demand law at different stages of protected cultivated tomato, effect of irrigating by moistube-irrigation in low pressure on the quality and physiological characteristic of protected cultivated tomato, find the characteristics of soil moisture diffusivity and movement regulation which irrigate by moistube-irrigation in low pressure, physiological regulatory mechanisms and quality change of protected cultivated tomato, reveal the irrigation technique index and water consumption characteristics of protected cultivated tomato which irrigate by moistube-irrigation in low pressure, establish the technology model of high efficiency water-saving facilities of moistube-irrigation in low pressure, the research results can provide the theoretic foundation and design parameter of the system for the technology of moistube-irrigation in low pressure which is recommendable to be used in South Xinjiang protected cultivation. |
