磷素肥料可以促进作物根系发育,增强吸收能力,提早成熟,增加产量。但土壤中的磷肥因有很多原因,使一部分磷不能被作物吸收利用,称为无效磷。磷菌肥施入土壤后,在生命活动的过程中能产生一种酸性物质,把土壤中的无效磷转化为有效磷,被作物吸收利用,促使农业产量的提高,据我县近几年的试验结果,凡使用磷菌肥的作物一般都增产20%左右,高的达30%以上。但磷菌在生命活动时间范围很小,使用时应尽量与种子或根部接触。为此现把使用方法介绍如下:(一)烟叶:①烟苗追肥,烟苗十字叶时,每亩可施一百斤,施后喷水,可以
Phosphorus fertilizers can promote crop root development, enhance absorption capacity, premature, increase production. However, there are many reasons for phosphorus in the soil, so that some phosphorus can not be absorbed by the crop and is called as invalid phosphorus. Phosphate fertilizer applied to the soil, in the process of life activities can produce an acidic substance, the soil of phosphorus into available phosphorus, absorbed by the crop to promote agricultural production, according to my county in recent years Test results, where the use of phosphorus fertilizer generally increase the yield of about 20%, up to 30% higher. However, phosphorus in the life of a very small range of time, use should be as far as possible with the seed or root contact. Now use the method is introduced as follows: (A) tobacco: ① top-dressing tobacco, tobacco cross-leaf, per kilogram can be applied one hundred jins, after spraying, you can
