根据发育阶段生长度日恒定的原理和温室栽培试验,将温室甜瓜生长发育阶段划分为播种期、幼苗期、伸蔓期、开花坐果期、果实生长盛期、果实成熟期,建立了温室甜瓜发育的动态模拟模型,并确定了发育阶段生长度日的参数,系统地预测甜瓜生长发育阶段。模型检验结果表明,温室甜瓜发育动态模拟模型具有较高的精确性。 According to the principle of constant growth stage and greenhouse cultivation experiment, the stages of melon growth and development in greenhouse were divided into seeding stage, seedling stage, spreading stage, flowering stage, fruit growth stage and fruit ripening stage. The dynamic simulation model was established, and the parameters of the growth stage and development stage were determined. The stages of the growth and development of melon were systematically predicted. The results of the model test showed that the simulation model of greenhouse muskmelon development has higher accuracy.
