穴播き式不耕起播種機の実用化に関する研究

一个凸摆在径向方向上连接到一个垂直旋转盘固定作为一个专用组件种植孔的形成。在旋转的前侧新制作了一个专门用于释放种子的部件。0.82m/s时的跳孔率由19%提高到14%。在原设置中，一穴两粒的比例仅为40%。该装置的一个重要特征是种植距离可以设置为相等。该特征用于制备试验组，其中在与标准相比具有一半行距和两倍种植距离的袋中进行播种。在相同种植密度下，该试验组的单株产量和单位面积产量比另一个试验组高15%左右，杂草干重减少到另一个试验组的3/4-1/2。

A convex pendulum attached in the radial direction to a vertically rotating disc was fixed as a dedicated component for planting-hole formation. A part dedicated to the release of seeds was newly made on the front side of the rotation. The ratio of skipped holes at 0.82m/s was improved from 19% to 14%. The ratio of two seeds placed in one hole in the original setting was only 40%. One important characteristic of the device is that the planting distance can be set as equal. This feature was used to prepare a test group in which seeding was conducted in zigzags with half the distance between rows and twice the planting distance compared to the standard. The yield per plant as well as per unit of area in this test group was about 15% higher than in another test group using the same planting density, with weed dry weight decreased to 3/4-1/2 that of the other group.
