Abstract:

Tomato cv. ‘Liaoyuanduoli’ was cultivated in order to study the effects on the growth and development of tomato seedlings by super absorbent polymers with different granularity in soil. The results showed that the height, stem diameter, the weight of leaf blade, the fresh and dry weight of tomato seedlings were increased. G value and sound seedling index were also improved. The photosynthesis of function leaves in tomato seedlings was enhanced. The chlorophyll contents and net photosynthesis rate of tomato function leaves were increased. Together, the results demonstrated that the medium granularity of super absorbent polymers had the best treatment efficiency in the growth and development of tomato seedlings.
