| 内容記述 | 1.化学肥料である硫安と有機質金肥である菜種油粕とを窒素源として, それぞれを元肥として全量を与えた場合(元肥区), 一部を追肥として分施した場合(分施区)の影響を桃及び梨の1年生苗木を供試し, ポット栽培で究明した。元肥は3月下旬の定植と同時に施し, 追肥は年間施用量の40%を6月上旬に施した。2.硫安は分施した方が生育に効果的であるが油粕は分施の効果が不鮮明である。3.流出する肥料成分は季節的には降雨状況に影響され, 窒素のうち硝酸態窒素は新梢の伸長旺盛な5月∿6月に激しく流出し, 以後は激減する。アンモニア態窒素の流出は硝酸態窒素にくらべると甚だ量的に少なく, 時期的にはおそくまで流出する。4.リン酸の流出は季節的にはおそくまで続き, 季節による変化は硝酸態窒素のような激変はなく, 量的にもいちじるしく少ない。5.カリの流出の季節的変化は硝酸態窒素ほどでなくおそくまで続き, 量的には窒素と同じように多い。 | |||||

| 内容記述 | We studied on the nutrient effect of some nitrogen fertilizers. In one case, whole quantity of the nitrozen fertilizers were used at the planting time in the late of March, and in another case, their sixty percent volume was used at the planting time and their forty percent volume was used at the early of June for the additional fertilizer. Ammonium sulfate and rape oil meal were employed for the nitrogen sources in this investigation. One-year-old peach and pear trees that were cultured in special conclete pots were used. The results of the investigation were as follow : 1) The divided application of ammonium sulfate was more effective to the growth of peach and pear trees than the one-time application at the planting, but the application of rape oil meal showed no significant difference between these two methods. 2) Amounts of nutrients in the soil water that ran off from the base of conclete pots depended on severely to the condition of the precipitation during the experiments. 3) The application of the whole quantity of ammonium sulfate used at the planting time was seemed to concerned to the nitrogen deficiency of the late season growth of trees. 4) Nitric acid nitrogen amounts in the soil water ran off most severely during the season from May to June, and after this season very slightly. 5) The fusion of ammonium nitrogen was quite less than that of nitric acid nitrogen through all seasons. 6) The fusion of phosphoric acid was the least amounts among the three nutrient elements. 7) The fusion of potassium was almost similar to that of nitric acid nitrogen. | |||||
