抛秧栽培是水稻栽培方式的一项重大改革 ,其中塑盘育秧抛栽是目前推广轻型栽培的主要方式之一。从宏观上讲 ,按计划盘数确定抛栽量是相对均匀的 ,但在微观环境下 ,由于人工抛撒 ,随机分布 ,没有划格移栽那样统一的行株距 ,必然会出现稀密不匀 ,使水稻个体所拥有的营养面积和生? Throwing rice cultivation is a major reform of rice cultivation methods, including plastic plate throwing seedling throwing is one of the main ways to promote light cultivation. From a macro point of view, according to the number of planted dishes to determine throwing planted volume is relatively uniform, but in the micro-environment, due to artificial disintegration, random distribution, there is no cross-transplanted line spacing is inevitable there will be uneven, So that rice individuals have the nutritional area and health?
