一、ABT生根粉浸种 ABT生根粉是一种高效、广谱性的植物生长调节剂。玉米播前用ABT4号生根粉15～20毫克/公斤溶液浸种6～8小时,可使种子扎根快,根系发达,出苗早而齐,植株长势健壮,增产11.3%。二、芸苔素内酯浸种芸苔素内酯又称油菜素内酯,简称BR,是一种新型的植物生长促进剂。用0.3～0.5毫克/公斤的芸苔素内酯溶液对玉米浸种12小时,能提高种子发芽率及发芽势,加速幼苗生长,增强抗逆能力,一般增产8.5%～14.1%。三、多效唑浸种多效唑为植物生长延缓剂。
First, ABT rooting powder soaked ABT rooting powder is a highly efficient, broad-spectrum plant growth regulator. Maize before sowing with ABT4 rooting powder 15 ~ 20 mg / kg solution soaking 6 to 8 hours, can make the seeds take root fast, developed root system, emergence early and Qi, plant growth robust, yield 11.3%. Second, brassinolide soaking Brassinolide, also known as brassinolide, referred to as BR, is a new plant growth promoter. Seed soaking with corn 0.3-0.5 mg / kg brassinolide for 12 hours could increase seed germination rate and germination potential, accelerate seedling growth and enhance resilience, generally increasing yield by 8.5% -14.1%. Third, paclobutrazol soaking effect paclitaxel for plant growth retardants.
