日本歧阜县惠那市一农户在长期的蔬菜生产过程中,总结出一套独特的蔬菜育种技术。 首先,把精选过的牛蒡种子置于一容器内,再将一般家庭用酱油原液倒入盛有牛蒡子的容器中,浸泡一昼夜。然后,在播种之前,用清水反复冲洗被酱油浸泡过的牛蒡种子,直至酱油色完全消失。实验证明,经酱油浸泡过的牛蒡种子与未经处理的种子作田间试验,而前者的发芽率几乎为100％。 A farmer in Huina, Gifu County, Japan, summed up a unique set of vegetable breeding techniques in the long-term vegetable production process. First, the selected burdock seeds in a container, and then the general home soy sauce liquid into the container filled with Arctium, soaking for a whole day and night. Then, before sowing, rinse the burdock seeds soaked in soy sauce with water repeatedly until the sauce color disappears completely. Experiments show that the soy sauce soaked burdock seeds and untreated seeds for field trials, while the former germination rate was almost 100%.
