试验采用裂区试验方法(主处理为肥力、副处理为品种),3次重复。分析了有限型沈农黑豆3号和辽黑1号两个黑豆品种在高肥(磷酸二铵225 kg/hm2)和中肥(150 kg/hm2)及无肥(对照)条件下的经济性状,成熟后每小区取10株进行考种,测定项目有株高、节数、分枝数、单株荚数、百粒重、单株粒重、单株粒数等。小区计产,并折合成公顷产量,取两年的平均值。结果表明:施肥可使株高增加、分枝数增多、干物质积累量和叶面积指数相应地提高,并随着施肥量的增加荚数、粒重、粒数和产量也随之提高,辽黑1号的百粒重高于沈农黑豆3。本试验两个供试品种沈农黑豆3号和辽黑1号的产量分别为3532.5 kg/hm2和3641.7 kg/hm2。
Test using split zone test method (main treatment for fertility, deputy treatment for the species), 3 times repeated. The economic traits of two Shennong-Heodou No.3 and Liaodai-1 black bean cultivars under the condition of high fertilizer (225 kg / hm2) and medium fertilizer (150 kg / hm2) and no fertilizer , Each district after maturity to take 10 test species, determination of project height, number of sections, branches, pods per plant, 100 weight, grain weight per plant, grain number per plant. Residential area production, and converted into hectares of output, take the average of two years. The results showed that fertilization could increase plant height, branch number increased, dry matter accumulation and leaf area index increased correspondingly, and pod number, grain weight, grain number and yield also increased with the increase of fertilizer application Black No. 1 hundred grain weight Shennong black beans 3. In this experiment, the yield of two cultivars Shennong Heidou 3 and Liaodigai 1 were 3532.5 kg / hm2 and 3641.7 kg / hm2, respectively.
