ABT生根粉是一种高效、广谱性植物生根、生长和增产的促进剂。1991年我省在小麦、玉米、水稻、花生、甘薯等作物上应用,示范面积11万亩,效果比较显著。一、水稻。全省水稻面积大部分集中在冀东唐、秦二市。春季气温低,缓苗慢、分蘖少是影响产量的一大障碍。因此,在唐山、秦皇岛示范200亩,结果是;秧苗素质提高;植株增长快;增产显著。如昌黎县在三叶一心期和拔节期,用10ppm的药各喷一次,亩穗数达32.2万,穗粒数102.4个,千粒重26.6克,亩产745.5公斤。分别比对照增加3.4万、11.5个、0.7克和169.2公斤,增产率达29.4％;在三叶一心期喷一次的,亩增产94公斤,增产率16.3％;
ABT rooting powder is an efficient, broad-spectrum plant rooting, growth and yield promoter. In 1991, the province applied wheat, corn, rice, peanut, sweet potato and other crops with a demonstration area of 110,000 mu and the effect was remarkable. First, rice. Most of the rice area in the province is concentrated in Jidong Tang, Qin two cities. Spring low temperature, slow seedling slow, less tiller is a major obstacle to yield. Therefore, in Tangshan, Qinhuangdao demonstration 200 acres, the result is; improve the quality of seedlings; plants grow fast; significant increase. Such as Changli County in the clover of a heart and jointing stage, with 10ppm of the drug spray once per mu number of 322,000 acres, 102.4 grains per spike, grain weight 26.6 grams, 745.5 kilograms per mu. Respectively, increased by 34,000, 11.5, 0.7 and 169.2 kg compared with the control, and the yield increase rate reached 29.4%. In the period of one-leaf clover spraying, the output of mu increased by 94 kg and the rate of increase was 16.3%.
