Abstract
The experiment was conducted to probe into physiological mechanism of early aging caused by plastic mulching on tomatoes. The result showed that plastic mulching made chlorophyll content in tomato leaves increase before initial harvest stage but decrease remarkably after harvest peak stage, made plant bleeding sap increase all the stages, and made photosynthesis of leaves as well as vigor of roots increase before initial harvest stage but decrease after harvest peak stage. It also increased contents of nitrogen, phosphorus and calcium on dry matter basis in leaves, and increased potassium content before green ripe stage but decreased that after initial harvest stage, and the effect was most remarkable at final harvest stage. The covering made magnesium content in leaves decrease at all the growth stages, and the effect was also most remarkable at final harvest stage. The tomato plants arise early aging at last growth stages. It seems that early aging was related to insufficiency ofpotassium, which resulted in soluble carbohydrate accumulation in leaves.
