试验所用品种为不知火及中生新千本,研究目的系针对日本西南部水稻产量不高是由于生长过旺,以致结实不良的这一说法而设计的,试验在不同肥力的土壤上,以不同时期和不同施量施用氮肥,使稻株的生长量和含氮量产生种种差异,以求找出(1)成熟较好的氮素营养和生长模式(各器官的干重)(2)抽穗前的氮肥施用
The species used in the experiment was ignorant of fire and a new one in middle school. The aim of the study was to design a rice plant with low yield of rice in Southwest Japan due to overgrowth and poor fruitfulness. The experiment was conducted in different fertile soil with different periods And different application of nitrogen fertilizer, so that the growth of rice plants and nitrogen content produced a variety of differences in order to find out (1) well-matured nitrogen nutrition and growth patterns (organs of the dry weight) (2) before heading Nitrogen fertilizer application
