| Abstract: |
| 【Background】Melon is an important horticultural crop, and the planting area and yield of Melon in China rank first in the world. With the improvement of living standards, consumers' demand for the yield and quality of melon is increasing day by day, realizing water saving, high yield, high quality and efficient production of melon and other Cash crop, it is an urgent scientific problem to be solved in modern agricultural production.【Objective】The purpose of this paper is to explore the response of the dynamic process of fruit growth and sugar accumulation, and fruit yield and quality to different water and calcium treatments, from which we proposed a suitable management mode of water and calcium .【Method】The experiment consisted of two irrigations: high water content W1, medium water content W2 (2/3 of W1) and lowhigh water content W3 (1/2 of W1),with two levels of calcium treatment:Ca1(0.68L/Plant in total) and Ca0, In each treatment, we measured the related growth physiological indexes of muskmelon.【Result】(1) “Tinglin” is a kind of high sucrose accumulation muskmelon variety, the diameter showed a single "S" curve, and the fruit growth and sugar accumulation trend are similarunchanged under different water and calcium treatments (2) Under high water condition, fruit diameter increase, fruit diameter size and fruit yield are the largest, but irrigation water use efficiency(IWUE) is the lowest. Under medium water treatment, IWUE and fruit quality were the best, while low water treatment had negative effects on fruit growth and reduced the final fruit yield. (3) Compared with no calcium treatment, the yield, fruit weight and IWUE of calcium treatment were increased, and the fruit hardness was increased and the titratable acid content was decreasedwhich alleviated the yield reduction effect caused by deficit irrigation to a certain extent, improved the fruit hardness, and reduced the titratable acid content.【Conclusion】Water and calcium can affect fruit growth and development, sugar accumulation, and final yield and quality. Medium water content with the application of calcium is the suitable management mode of water and calcium in Muskmelon. Our results have important implications for production of muskmelon. |
