Abstract:
Taking melon variety ‘Jingshuai’ as test material,with soilless nursery nutrition organic substration，effect of 20% (T1),40% (T2),60% (T3),80% (T4),100% (T5) five kinds of water content substrate on physiology and photosynthetic characteristics of melon were studied，to explore suitable substrate water content for melon plug-seedling in Gobi District of Xinjiang Province,The results showed that T1 treatment and T5 treatment decreased the rate of carboxylation of melon leaves,thereby inhibited the photosynthesis of melon plants.While T1 (20%) treatment,significantly reduced free water/bound water ratio,chlorophyll a/b ratio in melon leaves,leading to its decline in photosynthesis.Comprehensive analysis of the test results showed,the proposed facility in the Gobi District of Xinjiang under the management of water melon plug-seedlings,relative water content of 60% to 80% was appropriate.
