本文以几年来营口地区杂交水稻的高产调查实例为依据,对其中的资料进行了一些统计和相关分析。从中提出了亩产1300斤以上的杂交水稻在栽培上应该注意的特点是:充分发挥分蘖的作用,努力争取有较高重量的单蘖,以提高收获指数;在利用分蘖的问题上要掌握降低分蘖节位和加强保蘖两个环节,以确保有效茎数,在中、后期的田间管理措施中,与防止地面节间过度伸长的同时,要促进最上部第一节间的长度,以改善株间的受光态势。
Based on the high yield survey of hybrid rice in Yingkou in recent years, this paper makes some statistics and correlation analysis on the data. It is proposed that more than 1300 pounds per mu of hybrid rice cultivation should pay attention to the features are: give full play to the role of tillers, strive for a higher weight of single tillers, to improve the harvest index; in the use of tillers to master the reduction Tillering nodes and tighten the tillering two links to ensure that the effective number of stems, in the late field management measures, and to prevent over-expansion of the ground section at the same time, to promote the length of the first section of the top to Improve the light-receiving situation between strains.
