花生素(TCBA)在花生、大豆植株上的喷施效果

The Effectiveness of Application of TCBA to Peanut and Soybeam

花生素(TCBA)是一种新型的植物生长调节剂。经多年在花生、大豆等作物上进行叶面喷施的小区试验和生产示范试验,都表现出明显的增产作用,尤其对花生的增产效果更显著,增产幅度可达15％以上。增产原因主要是能调节作物营养生长与生殖的关系,使之协调发展,同时能捉高作物叶片中叶绿素的含量和光合效率,并能促进光合产物向产品器官中运输。

TCBA is a new kind of plant growth-regulating agent Syntheszed in Shenyang Agricultural University. The experiments results showed that the yields of peanuts and Soybeans could be visibly increased by spraying 200ppm of TCBA upon their leaf surface durng full bloom. The yield of peanuts increased by more than 50%. The main reason is that TCBA may regulate the relationship between plant vegetative growth and its repro- ductive growth, increase the amount of chlorophyll in leaves, raise the photosynthetic efficiency and promote the transportation of the photosyn- thetic products to their parts.
