科学试验和各地生产实践早已证明,使用硫酸铵、硝酸铵作种肥是经济有效的施肥方法。氧化铵、尿素、碳酸氢铵、磷酸铵等,是否也可以作种肥,因过去我省使用不多,还不能肯定。为探求这些化学肥料作种肥对种子发芽率和后期生长发育的影响,我们先后在省农业科学院内作了小区和盆栽试验。小麦品种为南大二四一九。并在肥西县园林公社晚茬瘠薄的黄白土上作了提高单位化肥增产率的种肥大区对比试验。小麦品种为当地迟白麦。现将其初步结果整理于下,供大家进一步研究和指导生产作参考。
Scientific experiments and production practices have proved that the use of ammonium sulfate, ammonium nitrate as seed fertilizer is a cost-effective fertilization method. Ammonium oxide, urea, ammonium bicarbonate, ammonium phosphate, etc., whether it can also be used as fertilizer, because in the past little use in our province, not yet sure. In order to explore the impact of these chemical fertilizers as seed fertilizers on the seed germination rate and later growth and development, we have made plots and pot experiments in the Provincial Academy of Agricultural Sciences. The wheat variety is Nanda 2419. And in the Feixi Garden commune stubble late yellow soil to make unit fertilizer to increase the rate of fertilizer and fertilizer area comparative test. Wheat varieties for the local late white wheat. Now its initial results sorted out for everyone to further study and guide the production for reference.
