广东蔗区现行的甘蔗播种形式,基本上有两种。一种是单行条播;一种是双行条播。单行条播一般接近于顶接;双行条播除了有一定的播幅之外,种苗间头尾有一定的距离,故有“狗脚迹”之称。现根据一般株行距的变化幅度,整理成下列的亩下种量检索表,供参考。其中株距方面,因为有单行和双行之分,为方便计算,不论单行和双行,株距多少,采取一丈(333厘米)内的放种苗数为计算基础。例如在一块蔗田中,通过几个点的调查,平均行距为3.2尺(相当于107厘米);一丈内的下种苗量平均为2 2条,查表得该田亩下种苗量为4125条。
There are basically two types of sugarcane sowing in Guangdong sugarcane planting area. One is single-line broadcast; one is double-line broadcast. Single-line broadcast is generally close to the top; two-line broadcast in addition to a certain broadcast, the seedling between the head and tail have a certain distance, it is “dog footprint ” said. Are based on the general range of line width changes, sorted into the following acres of species search table, for reference. Among them, the plant spacing, because of single and double lines of points, for the convenience of calculation, regardless of single and double lines, how much spacing, to take Zhang (333 cm) within the number of seedlings planted basis. For example, in a piece of sugarcane field, the average row spacing is 3.2 feet (equivalent to 107 cm) through several points of investigation; the average number of seedlings under a hill is 22, and the number of seedlings per mu under the table is 4125 Article.
