近年来关于水稻最适密度有过许多研究和报道，但就本地区高产水稻栽培最适密度模式的探讨还研究较少。为了探讨本地区水稻高产栽培的最适密度模式，从而为生产上合理密植提供科学依据，应用近代数理统计学方法，进行了藤系１３８为应试品种的不同密度比较试验，提出适应延边地区气候特点和产量水平的最适密度模式。通过整理分析，得出本地区取得公顷９．４２１吨稻谷的最适密度为：１８．７４×１０４苗／１０ａ，密植形式采用２３．１＋９．９ｃｍ４穴正条式小四角，并分析了产量及其因素间的关系。
In recent years, there have been many researches and reports on the optimum density of rice. However, the research on the optimum density model of high yielding rice cultivation in this area is still less studied. In order to explore the optimum density model for high-yield cultivation of rice in the region, and to provide a scientific basis for reasonable planting density in production, the modern density-based mathematical methods were used to compare the density of Fujuyou 138 with the tested varieties. And the optimal density pattern of production levels. Through the analysis, the optimal density of 9.421 tons of hectare in the area was obtained: 18.74 × 104 seedlings per ten years, 23.1 + 9.9cm4 points in dense planting form, and the yield and The relationship between the factors.
