西门莲是福建莲子中产量和品质较优的品种,它可能是白莲与红莲自然杂交的一个杂种,生育期180～190天。地下主、侧茎均能开花结实,以主茎开花结实较多。叶片分浮叶和立叶,立叶直径达70～80厘米时,产量最高。花为单生两性花,开花时经“三开两合”,属雌蕊先熟型的自花异交授粉。受精子房发育成坚果,历期28天左右。根据西门莲生育特性,可通过选好莲田种好绿肥、促控莲叶多结莲子、加强授粉提高结实率、控制侧茎争取主茎多结实等技术来提高产量。
It is probably a hybrid between Bailian and Honglian, whose growth period is 180-190 days. Underground Lord, side stems can flowering sturdy, stalks flowering stalks more. Foliage leaves and leaves stand leaf, leaf diameter up to 70 ~ 80 cm, the highest yield. Flowers for the solitary bisexual flowers, flowering through the “three open two together,” is a pistil first cooked self-pollinated pollination. Fertilized sperm into nuts, a period of 28 days. According to the reproductive characteristics of Simmental, we can increase the yield by selecting good green manure for lotus seed, promoting lotus-bearing lotus root, strengthening pollination to improve seed setting rate and controlling lateral stems to gain more stems and more sturdiness.
