内陆干旱灌区次生盐渍化土壤适宜种植菊芋品种筛选

摘要：目的：为内陆干旱灌区次生盐渍化土壤筛选适宜种植的菊芋品种。方法：通过对引进的品种与当地传统种植品种比较试验，采用随机区组试验设计方法进行比较。结果：与当地传统种植品种比较，引进品种产量均高于当地品种，其中以B1产量最高，达59285.71kg/hm2，与其它品种产量呈极显著差异，其次是R4、B8；秸秆产量以B8最高，达28094.29 kg/hm2，其次是R3和R4。结论：在永登县秦王川灌区次生盐渍化土壤上进行比较试验，宜推广B1、R4、B8三个菊芋品种，其在盐碱地具有较高的经济产量和生物产量，综合效益较高。关键词：菊芋；干旱灌区；次生盐渍化土壤；品种筛选

To Screening Helianthus Tuberosus Variety of Suitable Cultivation for Secondary Salinization Soil of Inland Arid Irrigated Area

By planting different varieties of helianthus tuberosus in soil salinization, to select suitable for the cultivation of arid saline areas northwest of New Varieties of the growth of helianthus tuberosus. To provide a technical basis for which Variety of Helianthus Tuberosus are planted in secondary salinization soil of Inland arid irrigated area Use randomized block design method to make an experiment, based on the test results to compare with new helianthus tuberosus varieties and trdditional varieties. Compared with the traditional local varieties, the introduction of varieties yield higher than CK, of which variety B1 is the highest yield, up to 59 285.71 kg/hm 2 , and showed significant difference than other varieties, followed by R4 and B8; In these varieties, the straw yield of B8 is the highest, reaching 28094.29 kg/hm 2 , followed by R3 and R4. The results showed that the helianthus tuberosus variety of B1, R4, B8 is suitable for promotion in secondary salinization soil of Inland arid irrigated area, this results show that these three varieties of helianthus tuberosus can have a higher economic yield, biological yield, and a better integrated efficiency in saline-alkali soil.
