舞草又称跳舞草,由于其小叶具有自身舞动的特异功能,所以深得人们喜爱。舞草开花多而结实少,自然授粉结实率仅为2%～5%,限制了它的传播。笔者近年对舞草进行了人工授粉试验,结果表明结实量是自然授粉的5～10倍,大大增加了种源。现将人工授粉的技术要点介绍于下: 1.花的结构舞草属蝶形花科多年生灌木,其花冠为蝶形,由旗瓣、龙骨瓣和翼瓣组成(依次见图1、2、3)。雄蕊为二体,10个雄蕊有9个花丝连合,1个单生,每个雄蕊由花丝和花药组成,位于花冠的内轮,花丝着
Dancing grass, also known as dancing grass, because of its leaflets with their own unique features dancing, so loved by people. Dancing grass flowering more and less strong, natural pollination rate of only 2% to 5%, limiting its spread. In recent years, I conducted artificial pollination experiments on grass and grass, and the results show that the yield is 5 to 10 times that of natural pollination, greatly increasing the provenance. Artificial pollination now introduced the main points in the following: 1. The structure of the flower Dancing is a genus of butterfly flower perennial shrub, the corolla is a butterfly, the flag flap, keel flap and flap composition (followed by Figure 1, 2, 3). Stamens are two-parted, 10 stamens with 9 filaments united, 1 solitary, each stamen composed of filaments and anthers, located inside of corolla, filaments
