植物生长调节剂在长效有机—无机复混肥料中的应用方法

Plant Growth Regulators in Long-term Organic Inorganic Mixed Fertilizer Application Method

植物生长调节剂一般每亩用量只需几克或几毫升,文章介绍将微量植物生长调节剂均匀加入复混肥料中的方法,包括以下步骤:(1)脲醛浆配制;(2)调节剂加入;(3)脲醛浆聚合;(4)含植物生长调节剂长效复混肥的生产。在脲醛浆反应时加入复硝酚钠、萘乙酸钠等植物生长调节剂,能有效地溶解到反应液中,待脲醛浆聚合后植物生长调节剂能均匀地分布在固相中,实现微量植物生长调节剂在复混肥料中均匀添加。

Plant growth regulator in long-term organic-inorganic compound fertilizer production method, which comprises the following steps： （1） ureaslurry preparation; （2） adding conditioning agent; （3） urea slurrypolymerization; （4） containing plant growth regulator long-acting fertilizer： urea formaldehyde polymer after drying. The effective content of mixed nitrogen, phosphorus and potassium fertilizer in three elements are calculated to press the N, P2Os, K20, N, P205, K2O weight ratio according to N ： P205 ： K20=14-18 ： 11-15 ： 11-15, plus the weight of organic matter from 15 % to 20 %, fully mixing granulation to obtain the urea formaldehyde containing organic - inorganic plant growth regulator compound fertilizer.
