甜菜种株为无限花序,自始花起直至种子收获时花序顶端仍有小花开放,而晚开花朵不能形成有效的种子,白白消耗种株的营养物质。因此,采种实践上凡有条件的地方,便采用种株人工摘尖的技术措施,以改善种子的品质,提高种子产质量。但人工摘尖限制因素较多,如因用工量大,难采用,在长势繁茂的采种田,株枝相连,田间处于封闭状态,若数人进田操作,将折损部分果枝。鉴 Beet species is an inflorescence inflorescence, from the beginning of the flower until the seed is harvested when the top of the inflorescence flowers are still open, and the later flowering can not form effective seeds, in vain consumption of plant nutrients. Therefore, the practice of mining where the conditions permit, they will use artificial seed picking technology measures to improve the quality of seeds and improve seed quality. However, there are many limiting factors for manual picks. Due to the large amount of labor and hard work, the growing branches are connected with the growing branches and branches, and the fields are in a closed state. If several people work in the fields, some branches will be damaged. Kam
