Adding Organic Fertilizer On Tomato Growth And Quality Of Greenhouse Grafting

Tomato is one of the staple vegetables in cultivars in China. According to the organic fertilizer characteristic and the promotion of food safety consciousness, the present study was undertaken to examine the change in growth、quality、yield by adding apply organic fertilizer and grafting. The results show that:1. Adding apply organic fertilizer can promote the tomato growth of self-rooted and grafted tomato. Under the same level of fertilizer, grafting can promote the stem diameter, and inflorescence, which is beneficial to strengthen seeding early and development. How ever, grafting restrains the stem length and it indicates that grafting is suitable for high de nsity cultivation.2. Organic fertilizer and grafting can improve the chlorophyll content of the leaves of tomato and promote photosynthesis. It also can promote the form and accumulation of or ganics and nutrients.3. The contents soluble sugar decreased. It shows that plant growth can be driven by organic fertilizer which can restrain the accumulation of soluble sugar. Meanwhile, graftin g can improve the content of soluble sugar and restrain the nitrates. It indicates that grafti ng plays a part in improving the fruit quality.4. The increasing of organic fertilizer can improve biomass and the accumulation of dry matter and fresh weight in various organs of plant. Grafting can improve the undergro und portion growth and absorption capacity under the same level of fertilizer, so it can hel p the growth of plant aerial portion.5. Adding organic fertilizer can raise the self-rooted and grafted seeding yield effecti vely, but not for the single fruit weight. There is no significant yield-increasing effect wit h the excessive fertilization. Grafting can ensure the high yield under the increasing of org anic fertilizer. Based on analysis, the test process of grafted seedlings on organic fertilizer of15000kg/667m2(J-3) has the best effect to growth and production in this study.
