“利丰收是一种新型植物生长调节剂.具有促进根系发生和生长,扩大叶面积,提高叶片光合能力,延缓叶片和根系衰老等作用.已广泛应用于各种作物,蔬菜,瓜果上,一般能增产10%～20%.我们于1996～1998年在内蒙古兴安盟扎賚特旗,进行了三年的水稻浸种试验,并同时在黑龙江省五常县和吉林省松原市进行多点生产示范,均取得良好效果.试验采用的水稻品种为“东农419号”,由东北农业大学提供.该品种生育期132天.试验、示范的“利丰收”粉剂由江苏省淮阴市环宇生物技术应用研究所提供.浸种药液浓度为万分之一(lg利丰收粉剂溶解在10kg水中),浸种时间为2小时,捞出后随即进行催芽.
“Li & Fung is a new plant growth regulator with the role of promoting root growth and development, expanding leaf area, increasing leaf photosynthetic capacity, and retarding leaf and root senescence. It has been widely used in various crops, vegetables, fruits, Generally increase production by 10% to 20% .We conducted a three-year rice soaking test at the Xing’an League Zhaju Teqi in Inner Mongolia from 1996 to 1998. At the same time, we carried out multi-point production demonstration in Wuchang County, Heilongjiang Province and Songyuan City, Jilin Province , All achieved good results.The rice variety used in the experiment was Dongnong 419, which was provided by Northeast Agricultural University.The growth period of this variety was 132 days.The powder of ”Li & Fung Harvest" tested and demonstrated by Huaiyin City, Jiangsu Province, Institute provided immersion liquid concentration of one ten thousandth (lg Li Feng Powder dissolved in 10kg of water), soaking time of 2 hours, remove the germination immediately after.
