| Abstract: |
| Based on the irrigation interval of 2 days, this study was conducted to evaluate the effects of different plant pan coefficient(Kcp=0.45, 0.60, 0.75 and 0.90) on the growth and physiological characteristics of drip-irrigated muskmelon under film mulch in greenhouse. Irrigation quantities were determined by water surface evaporation (Epan) measured by a standard 0.2 m diameter pan. The results showed that: (1) The ground temperature (15 cm) of muskmelon was remark
ably influenced by different water treatments. Among them, the treatments of T2 and T3 were more suitable to the growth of muskmelon; (2) The leaf size and deve
lopment of muskmelon was greatly influenced by different water treatments. Based on the interval of 2 days, keeping the plant-pan coefficient(Kcp) as 0.6 not only were of advantage to the development of leaf, but also obtained the maximal leaf area; (3) Through analyzing plant height, stem diameter/plant hei
ght, biomass, root/shoot, leaf water status, leaf photosynthetic index, the results indicated that keeping the plant pan coefficient(Kcp) as 0.6 was
more suitable to the development of drip-irrigated muskmelon under film mulch in greenhouse. Water saving and efficient management was reached in the treatment
of T2. |
