合理密植是水稻增产的有效措施。我省多年来推行合理密植,对提高水稻单位面积产量起了重要作用。合理密植的正确含义应是:合理安徘每亩的基本苗和行株距,在保证足够基本苗的前提下,达到最大的增产效果。但密植增产效果的发挥,同密植方式、栽培条件、自然因素密切关联。为使生产上能比较正确地选用合理的栽插密度,本文旨在阐明密植增产作用的同时,讨论不同密植方式的增产效应、密植与栽培条件的关系。
Reasonable and close planting is an effective measure to increase yield of rice. For many years, our province has implemented reasonable and close planting and played an important role in improving rice yield per unit area. Reasonable and close planting should be the correct meaning: a reasonable amount of seedlings per acre and line spacing, to ensure adequate basic seedlings under the premise of achieving the maximum yield. However, the effect of close planting and yield increasing is closely related to the close planting mode, cultivation conditions and natural factors. In order to make the production more appropriate selection of planting density, the purpose of this paper is to clarify the role of close planting and yield increase at the same time, discuss the different planting mode of yield effect, close planting and cultivation conditions.
