Effects Of Commercial Organic Manures On The Growth And Development And The Fruit Quality Of Greenhouse Watermelon

Three kinds of commerial organic manure, which were extensive used for vegetable production in Shandong, were chosen to study their effects on the growth and development and fruit quality of grenenhouse watermelon. There were two control treatments, one was the traditional organic manure, chicken manure, and the other was no organic manure at all. This study will provide theorical gists for the exploiture and development of commercial organic manure. The chief results were as follows:1.Using organic manure benefited for the plant growth and the fruit development of watermelon.The wine length of watermelon plant of each treatment with organic manure was longer than that of the control treatment. The differences among effects of organic manure on the RGRs of the trunk, the first branch and the second branch in stageâ… (from breedling stage to blossom stage), stageâ…¡(from blossom stage to early bearing stage), stageâ…¢(from early bearing stage to inflated fruit stage), were all up to 0.05 level. The rate of growth of the wine was the largest in stageâ…¡as for each treatment, and that of the plant with chicken manure was larger than the others, and that of the brough, the first branch and the second branch were increasing in turn.The stem diameter of watermelon plant of each treatment with organic...
