| 内容記述 | 緩傾斜で肥沃な土壤に生育する7年生の桃樹2木を供試し, 1本は区劃根群採集法により, 他は塹壕式根群露出法により根群の分布様相を究明した。その概要は次の通りである。1) 地上部生体重210kg, 根量101kg強, T-R率は2.08であつた。2) 水平的分布は半径4m以上に達し, 根量最多は0∿1mの範囲であつた。3) 垂直的分布は地表下120cm以下に達し, 最多に存在するのは0∿30cmの範囲であつた。4) 根群の様相は多分に水平的で, 斜面の上方により多く伸展していた。5) 根群は細根9.56%, 小根11.39%, 中根17.72%, 大根35.37%及び根幹25.96%であつた。6) 細根は特に堆廐肥の施与された部分に分岐し, 細根の分岐には堆廐肥等の有機質の存在が重要な影響を及ぼしていた。 | |||||||||||||||||||

| 内容記述 | We studied on the root-system of two 7-years old peach trees, (Okubo and Rikaku), growing on the low gradient slope in winter, 1956. In the case of Okubo, the soil of the root zone was divided into five concentric circles, each extending 0-1m, 1-2m, 2-3m, 3-4m, and 4-5m, from the trunk, and were separated into five depthes respectively, i.e. 0-30cm, 30-60cm, 60-90cm, 90-120cm and the other deeper than these, that were to say, all forming 25 blocks. The root contained in each block was arranged into five classes by their thickness, i.e. fine root under 0.5cm in diameter, Slender ones 0.5-1.0cm, medium ones 1.0-2.0cm, large ones over 2.0cm and Crown root. In the case of Rikaku, WEAVER'S Trench method was adopted. At the reach of 30cm from the trunk, a trench was dug, to a convenient width, paralleling to the slope. The root zone between the trunk line and the trench was exposed. The results as follow : 1) In Okubo, total weight of its top was 210kg, Roots 101kg, and its top-root ratio was 2.08. 2) The roots, in horizontal, developed to the area over 4m from the trunk, and their most density were consisted in the zone of 0-1m. 3) The roots, in vertical, penetrated under than 120cm from the surface and their most density were consisted in the zone of 0-30cm. 4) The root distribution was more horizontal than vertical and was vigorous in the upper part than downward part of the slopl. 5) In Okubo, the root consisted of 9.56% in fine roots, 11.39% slender roots, 17.72% medium, 35.37% large, and 25.96 root crown. 6) Particularly the heavey distribution of fine roots was observed in the zone at which the manure was included enough. | |||||||||||||||||||
