Abstract


Trough sand culture of melon (Cucumis the melo L.var.reticulatus Naud.) \high, stem diameter, leaf area, chlorophyll content, dry matter accumulation, fruit type index, yield, quality and water use. The the melons under different irrigation frequencies moisture variation analysis; explore the different irrigation frequencies melon Physiology and Ecology, growth and development, fruit growth and quality, water use may affect factors; form Daylight greenhouse melon cultivation conditions of non-cultivated land under irrigation system explore and improve water use efficiency to improve the establishment and improvement of the irrigation system of non-cultivated melon and melon yield excellent production has a certain theoretical significance. The main results of this test are as follows: 1. Melon conventional irrigation compared the melon plant height slightly lower increase in irrigation frequency, stem diameter increased significantly. And high frequency irrigation compared with conventional low-frequency irrigation, in terms of growth rate showed the the vegetative growth pre slower late vegetative growth and reproductive growth phase significantly improve the phenomenon. Increased irrigation frequency melon amount of longitudinal growth has been reduced, and a significant increase in the amount of lateral growth. Increase in irrigation frequency melon plants leaf area decreased slightly, but with no significant difference between the control treatment. Increase in irrigation frequency melon leaf chlorophyll content increased significantly. This may be caused by high frequency treatment under the fruit dry weight, root dry weight and plant dry weight and control treatments exist significant differences in the physiological basis of where. 3. Increase in the frequency of irrigation on fruit weight, fruit type index (fruit diameter, fruit length, flesh thickness) and yield, leaf dry weight, stem dry weight and so had no significant impact, but be root dry weight, shoot ratio, fruit dry weight, dry weight of plant to produce a more significant impact. Increase in the frequency of irrigation under high frequency irrigation treatments melon in terms of quality is significantly better than the control low frequency processing W1. Increased irrigation frequency makes more obvious increase in the free amino acids in the melon fruit, fruit soluble total sugar, soluble solids content increased significantly. Increased irrigation frequency does not make a significant increase in fruit weight lower frequency of irrigation, but will in the processing of fruit dry weight and plant dry weight was significantly higher than that of conventional low-frequency processing melon. Increase in irrigation frequency makes the water use efficiency compared with the control increased slightly, but the difference between each treatment did not reach the level of significance. Transpiration efficiency, high-frequency irrigation treatments W3 W2 were higher than the control treatment W1 6 In summary, under the same conditions as irrigation quota, increasing irrigation frequency can significantly increase the plant's stem diameter, chlorophyll content and IF irrigation treatment roots dry matter accumulation and improve shoot ratio, significantly to increase melon fruit free amino acids, total soluble sugars and soluble solids content, improve fruit quality. Therefore, agricultural production, combined with the actual situation, to ensure reasonable conditions of irrigation quota, an appropriate increase in irrigation frequency promote melon growth, effective measures to improve the quality.
