为探讨中花16的高产高效栽培技术,在田间试验条件下,研究了不同种植密度和肥力水平对中花16产量及农艺性状的影响。结果表明,随种植密度和肥力水平的提高,分枝数、结果枝数、荚果数和饱果数均呈下降趋势。不同肥力条件下,单株叶面积和群体叶面积系数表现一致,而不同密度条件下,两者差异明显。不同肥力与密度互作中 F2×M1组合的产量达301.5kg /666.7m2,显著或极显著高于其他互作组合。综合分析认为,在本区域生态条件下,中花16作为露地春花生种植的适宜密度以0.85万穴/666.7m2为宜,肥料以一次性基施为好,基肥中应氮、磷、钾配合,并配施速效氮肥。

To investigate the high yield and efficient cultivation technique of Zhonghua1 6, field experiment were conducted to study the effects of different planting densities and fertility levels on the yield and agronomic characters of Zhonghua1 6.The results showed that the branch number, pod branch number, pod number, and plump pod number per plant all decreased after the increasing of planting density and fertility level.The leaf area per plant and leaf area index were synchronously changed under separate fertility levels, but differently performed under separate planting densities.In the orthogonal interaction experiment of fertility× density, the highest yield was attained as 301.5 kg /666.7m2 in F2 ×M1 , which was significant or extremely significant among various combinations. In conclusion, based on the ecological conditions of experimental area, 0.85 holes /666.7m2 is the most suitable planting density for cultivation of Zhonghua1 6 in spring without film mulching.Fertili-zation should include base fertilizer (N-P-K) and the supplement of quick effective nitrogen.
