种植密度和施肥配比对红小豆形态指标及产量的影响

Effect of Planting Density and Fertilizing Proportion on Adzuki Bean Yield

该研究以2个红小豆品种珍珠红和宝清红为试材,设置不同种植密度和施肥配比组合,研究了种植密度和施肥配比对红小豆形态指标和产量的影响。结果表明,种植密度和施肥配对红小豆形态指标和产量的影响显著,适合黑龙江省西部地区红小豆的最佳种植密度是21万株/hm^2,与之配比的施肥组合是尿素60.3kg/hm^2、二铵154.2kg/hm^2、硫酸钾61.8kg/hm^2。

This study was conducted with two adzuki bean varieties ZZH and BQH to study the effect of planting den- sity and fertilizing proportion on adzuki bean yield.The results showed that ： adzuki bean yield was influenced signifi- candy by planting density and fertilizing proportion, and the optimum density was 21plants/hm2, optimum fertilizer composition was 60.3kg/hm2 of urea, 154.2kg/hm2 of diammonium, and 61.8kg/hm2 of potassium sulfate which is suit- able for western region of Heilongjiang Province.
