[Effects of moisture content in organic substrate on the physiological characters, fruit quality and yield of tomato plant].
With tomato cultivar Qifen as test crop, this paper studied its growth, physiological characters, fruit yield, fruit quality, and water use efficiency (WUE) under effects of relative moisture content of organic substrate. The results showed that with increasing moisture content in organic substrate, the plant height, stem diameter, node length, leaf area per plant, leaf pigment content, water potential, osmotic potential, root vigor, and fruit yield increased markedly, but fruit quality and WUE decreased significantly. Considering from the aspects of fruit yield, fruit quality and WUE, 80% moisture content of organic substrate could be used as a favorable quantitative index for the water management of tomato cultivation, under which, 26 kg x m(-2) fruit yield could be achieved. If only considering fruit quality, 50% moisture content could be used as the index for water management.
