厚皮甜瓜的生长发育过程大致可分为发芽期、幼苗期、伸蔓期和结果期四个阶段。不同生育阶段植株的器官形态有不同的变化;在同一生育阶段,因栽培环境的改变,技术措施的差异,也会直接影响植株的生长发育,进而使器官形态有所不同。只有掌握厚皮甜瓜的形态变化,并按照其生育规律进行科学管理,才能种植成功,获取较高的经济效益。一、发芽期的形态诊断从种子萌动到子叶展开为发芽期。厚皮甜瓜发芽适温为28～32℃,在此条件下一般3～4天可出齐苗。温度低于25℃时发芽慢且不整齐;低于15℃,多数不能发芽。若覆土过
Muskmelon growth and development process can be divided into germination, seedling stage, extending and fruiting four stages. Different morphological changes of plant organs in different stages of growth; in the same growth stage, due to changes in cultivation environment, technical measures will also directly affect the plant growth and development, and thus make the organ morphological differences. Only to grasp the morphological changes of muskmelon, and in accordance with their reproductive laws for scientific management, in order to plant success, access to higher economic benefits. First, the germination of the morphological diagnosis from the seed germination to the cotyledon for the germination period. Thick skin melon germination suitable temperature is 28 ~ 32 ℃, in this condition, usually 3 to 4 days can be Qi plate. When the temperature is below 25 ℃ germination slow and irregular; below 15 ℃, the majority can not germinate. If overburden
