| 摘 要： | 以毕引2号为材料,研究施用有机肥对马铃薯农艺性状的影响、不同施肥量对马铃薯淀粉含量及商品薯率的影响、施用有机肥对马铃薯产量的影响以及施肥量和马铃薯产量的相关性分析。结果表明:马铃薯株高随着施肥量的增加呈先上升后下降,主茎数则随着施肥量的增加而减少。在A4(4 500 kg/hm~2)处理下,马铃薯株高、淀粉含量、商品薯率及产量分别为38.4 cm、18.2%、60.1%、35 638.9 kg/hm~2比CK(农户习惯施肥)处理下,分别提高了7.3%、2.3%、22.9%、24.2%,且除淀粉含量外,其它均达极显著差异水平。

Effects of Organic Fertilizer Regulating on Agronomic Traits and Yield of New Potato Varieties Biyin No.2 |

| Abstract: | Using Biyin No.2 as material, this paper researched the effects and correlations of organic fertilizer and its amount to the agronomic characters, the yield, the starch content, and the commodity rate of potato. The results showed that the plant height rose ifrst then fell with the increase of fertilizer, while the main stem number decreased. Under A4 (4500 kg/hm2) treatments, the plant height, starch content, commodity rate and yields of potato were 38.4 cm, 18.2%, 60.1% and 35 638.9 kg/hm2, 7.3%, 2.3%, 22.9%, 24.2% higher than that of the control (CK), all of them reached extremely signiifcant difference level except the starch content. |
