[Method] Light-conversion films and common films were com- pared in terms Of light, air and soil temperatures. [Result] Vegetable greenhouse performed better in transmission of light, which would also improve air and soil tem- perature. [Conclusion] The comprehensive properties of vegetable light-conversion films proved better compared with common greenhouse, which improves light condi- tions for crops.展开更多

[Method] With soils from an ancient course in the Yel ow River as materials, acrylate SAP was taken as water retention materials to conduct the test. [Result] With 0.2%-0.4% SAP added, dewatering period of sandy soil extended after irrigation; the period of water retention quantity over 10% last for 42 d, which was significantly more than that of the control group in 16 d （saturated water reducing to 10%）; water retention effect proved better at the 2nd irrigation without soil stirring compared with the 1st irrigation. [Conclusion] The mixture of SAP with sandy soils promotes water retention in soils.展开更多

[Method] Environmental factors of biodegradable mulch of starch and common mulch were collected to make analysis and compar- isons on temperature, ground temperature, and illumination intensity with different mulches. Furthermore, the germination rates of broach bean and garlic were mea- sured with mulches covered. [Result] The comprehensive property of biodegradable mulch of starch performed better. [Conclusion] The biodegradable mulch of starch could reduce environmental pollutions and the application would be recommended.展开更多

Protected horticulture is independent to some extent, instead of relying greatly on nature, targeting full use of soil, climate and biological potential. The research concluded production characteristics of protected horticulture and analyzed the application of protected hor- ticulture intelligent monitoring system in protected greenhouse cultivation. In addition, the future development was proposed on protected horticulture intelligent monitoring system.展开更多
