Melon seeds in Northeast China are not suitable for planting in southern China. Melon, also called melon. Mainly divided into thin-skinned melon and thick-skinned melon. Thin-skinned melon originated in southwest China, and northeast and north China of China are the main producing areas of thin-skinned melon. Thin-skinned melon, the fruit is small, soft and thin, which is not resistant to storage, but has strong stress resistance. Spring sowing and summer harvest are mostly used. In the southern part of China, the climate in spring is rainy and humid, and the temperature is low, so planting in the southern part of China is not conducive to survival.

The cultivation of muskmelon requires warm and dry climate and large temperature difference between day and night. Most of them are planted in Xinjiang and Gansu in the northwest of China. It can't be cultivated in the open field in northeast, north and south of China. Therefore, in the northeast and east of China, thin-skinned melon is dominant, and in the arid area of northwest China, thick-skinned melon is dominant.
