Studies On Cultivation Techniques With Humping Support Of Mini-Watermelons

Since mini-watermelon varieties had been imported mainland of China, because most of mini-watermelon varieties is with thickly percarp, easily dehiscent fruit, and highly price, Most of these were planted in dependency. They were planted on the ground, covered with tri-level plastic membrane in early spring, or planted floor stand in high plastic shed in spring and on the ground in low plastic shed in full in Zhejiang province. Mini-watermelons are less planted in open field because of the more dehiscent fruit and lowly quality.In 2000, it was haphazardly found that the mini-watermelon's yield and quality had been improved by scramble on the trees. After then, I began studie on cultivation techniques with humping support of mini-watermelons.By the results of varietals yield test, mini-watermelon varieties so as 'Zaochunhongyu', 'Sweet', 'Texiaofeng', 'Nabite',.etc, are fit for this technique. By the results of date test, the fit plant date is from Apr 10^th to May 20^th , especially from Apr 20^th to May 20^th . By the results of density test, double row cultivation, 80cm spacing in the rows is the best. By the results of graft test, rootstock varieties so as 'Jinxinzheyihao', 'Anjiyuanhugua', 'Hangahouchangua', ' warrior' have high affinity and success ratio with the 'Sweet'. Use these 4 rootstock varieties, it is no influence about the fruit surface and less influence on quality on 'Sweet'. Use 'Jinxinzheyihao', 'Anjiyuanhugua' 'Hangahouchangua' and ' warrior' as rootstock, it can observably improve the resistance of Fusarium oxysporum f.sp. mvewm(E.F.Smith) Wolle). 'Jinxinzheyihao', 'Anjiyuanhugua' and'Hangahouchangua' can observably improve the resistance of Colletotrichum orbiculare (Berk.& Mont)Arx But ' warrior' can't improve the resistance of Colletotrichum orbiculare (Berk.& Mort)Arx. By the study of Matrix, use the materials such as burnt marl which is customarily seen in farmhouse as Matrix. We also may use the soil which never been plant watermelon in the past 5years as Matrix. The Matrix is separated from self-soil by plastic membrane. This method can most observably reduce the rate of Fusarium oxysporum f.sp. niveum(E.F.Smith) Wolle). This is one of the available methods that solved the problem about watermelon continuous cropping. Use the burnt marl which has been burnt as Matrix, it lost most of the organic matter of the soil. We must add organic matter and nitrogenous fertilizer in this Matrix. If we use this Matrix or new soil separated from self-soil by plastic membrane , we should cooperate it with trickle irrigator. We can control moisture of the soil accurately. Gravitational trickle irrigator is a easy to predominate. Adding any nutrient in liquid of trickle irrigator, it can greatly improve the yield of watermelon. It can Improve the plant ability of Counteracting adversity. It also can extend the harvest period . It can made watermelon one plant and more batch. It can greatly improve the economic benefit of watermelon planting.
