一种烤烟育苗营养肥
摘要：
本发明公开了一种烤烟育苗营养肥，其具体成分和配比为硝酸磷肥35‑50%、磷酸二氢钾10‑15%、硝酸钾25‑35%、硝酸铵钙8‑12%、硫酸镁0.1‑3%、氯化钙0.05‑0.1%、钼酸铵0.01‑0.05%、硫酸锰0.05‑0.1%、EDTA锌0.1‑0.5%、EDTA铜0.1‑0.5%、EDTA铁0.1‑0.5%、农用硝酸稀土0.01‑0.05%、硼酸0.1‑0.5%，N：P2O5：K2O比为1.8‑2：0.8‑1:1.8‑2，硝态氮与铵态氮的比为5‑7:5‑3。本发明首先根据烟苗生产需求及生产要求，选用各种肥源，即可以配备成营养液水剂，又可以生产成粉剂。使用本发明提供的所述烤烟育苗营养肥培养出的烟草茎杆粗、叶色绿和根系多，烟苗成苗率高，能有效提高烟苗成苗素质，缩短成苗期和还苗期。
摘要（英）：

The present invention discloses a flue-cured tobacco seedling growing nutrition fertilizer comprising the following specific components: 35-50% of nitrophosphate fertilizer, 10-15% of potassium dihydrogen phosphate, 25-35% of potassium nitrate, 8-12% of calcium ammonium nitrate, 0.1-3% of magnesium sulfate, 0.05-0.1% of calcium chloride, 0.01-0.05% of ammonium molybdate, 0.05-0.1% of manganese sulfate, 0.1-0 .5% of EDTA zinc, 0.1-0.5% of EDTA copper, 0.1-0.5% of EDTA Fe, 0.01-0.05% of agricultural nitrate rare earth, and 0.1-0.5% of boric acid, N: P2O5: K2O ratio is 1.8-2: 0.8-1: 1.8-2, and nitrate nitrogen and ammonium nitrogen ratio is 5-7: 5-3. First, a variety of fertilizer sources are selected according to tobacco seedling growing demands and production requirements for preparation into a nutrient solution water agent or preparation into a powder agent. Tobaccos cultivated by the flue-cured tobacco seedling growing nutrition fertilizer are thick in stems, green in leaves and more in roots, and high in tobacco seedling development rate, tobacco seedling development quality can be effectively improved, and seedling development term and seedling term are shortened.
