| 摘 要： | 应用多点联合正交设计，研究了湖南蔗区ＣＰ６５－３６７的适宜下种量和Ｎ、Ｐ、Ｋ施用量，结果表明，下种量和施氮量分别是影响甘蔗产量一含糖量的主要和次要因素。增施磷、钾肥效应不明显。文中对有关的试验结果作了单独的和综合的分析，并对较好的因素水平取值范围提出建议。

| Abstract: | An orthogonal design for joint experiment for four farms was employed tostudy proper rates of planting and K. P. K fertilization for CP65-357 in Hunansugarcane producing areas. The results showed that the rate of planting was theprimary important factor affecting cane and sugar yields, and the rate of nitrogenappl teat ion was the secondary. No significant effects resulted from increasing ratesof phosphorous and potassium application were found under the condition of thisexperiment. Individual and comprehensive analysis of the results from four farms werecarried out, and the proper levels of the experimental factors were recommended. |
