[Effects of air temperature, solar radiation and soil water on dry matter accumulation and allocation of greenhouse muskmelon seedlings and related simulation models].
With different sowing dates and irrigation upper limits, the effects of air temperature, solar radiation and soil water on the dry matter accumulation and allocation of greenhouse muskmelon seedlings were studied, with related simulation models established. The results showed that the dry matter accumulation and allocation of the seedlings had correlations with the changes of effective accumulative temperature, accumulative solar radiation, and irrigation upper limits at different seasons in a year, but the correlation coefficients differed with sowing dates and irrigation upper limits. Comprehensive analysis showed that the dry matter accumulation model was an exponential function, while the dry matter allocation model was a conic function, both of which were driven by effective accumulative temperature. The constant term in the functions was driven by accumulative daily temperature difference and accumulative solar radiation, and the correlation was a linear function. Model test showed that the models were able to objectively simulate and predict the changes of plant dry matter accumulation and allocation, and possessed practical value for the growth analysis and production management of muskmelon seedling.
