作物在田间的排列与分布问题与合宜密植问题有很密切的关系。对这两个问题的研究都是为了使植株能够充分地利用日光和地力,达到高产。如果一块田的植株总数是合宜的,但植株的排列和分布很不合理,则合宜密植的优越性仍不可能表现出来。从理论上说,植株在田间分布得愈均匀愈好,但是植株本身有较 The arrangement and distribution of crops in the field are closely related to the issue of proper planting. Both of these issues have been studied in order to allow plants to make full use of the sun and soil to achieve high yields. If the total number of plants in a field is appropriate, the arrangement and distribution of the plants are not reasonable, and the superiority of proper density is still not possible. In theory, plants are more evenly distributed in the field, but the plants themselves are better
