皇嘉天然芸苔素是直接从植物体内提取的最新一类高效、广谱、无毒植物生长调节剂,它能促进植物根系发育,均衡各部分生长,增强抗逆能力等。为摸清其在直播稻上的应用效果,1998年在直播早稻的籼、粳不同类型品种上进行浸种对比试验,现将结果报告如下。1 材料方法 0.15%皇嘉天然芸苔素乳油系浙江省义乌市皇嘉生化有限公司生产,药剂浸种处理浓度为10000倍。直播早稻品种为中熟早籼Z90—15,特早熟早粳春江早5105。试验安
Huangjia natural brassinolide is the latest type of high efficient, broad-spectrum and non-toxic plant growth regulator directly extracted from plants. It can promote plant root development, balance the growth of various parts and enhance the resistance to stress. In order to find out its application effects on direct seeding rice, we conducted soaking contrast experiments on different varieties of indica and japonica rice in direct seeding early rice in 1998, and the results are reported as follows. 1 Materials and methods 0.15% Huangjia natural brassinin EC Department of Yiwu City, Zhejiang Province Wong Ka Biochemical Co., Ltd. production, medicine soaking seed concentration 10000 times. The direct-seeded early rice varieties are Zhongzao Zhanzhan Z90-15, especially early-maturing early spring Chunjiang 5105. Test safety
