Abstract:

The field experiments were carried out in arid region in Xinjiang Province and cold non-infield in Qinghai Province to study the cultivars comparison of Helianthus Tuberosus L. and intensive planting technology of low cost and high quality. The results were as follows: there were variances of biological characteristics among Nanyu 1, Qingyu 2, Qingyu 1 and Nengyu 1 in Qinghai. The tuber yields of Nanyu 1 and Qingyu 2 were higher than the other cultivars. The biological characteristics of cultivars in Xinjiang differed from those in Qinghai. The tuber yield of Nanyu 1 was far higher than the other cultivars in Xinjiang. The tuber of Nanyu 1 with the treatment of E were highest, and under the treatment of C were lowest. The tuber amount of biomass of Nanyu 1 was different under different treatments. Like Nanyu 1. The tuber yield of Qingyu 2 with the treatment of E was highest, and under the treatment of C was lowest. The tuber amount of biomass of Qingyu 2 was also different under different treatments in Xinjiang. The tuber of Nanyu 1 with the treatment of E was highest, and under the treatment of B was lowest in Qinghai. The tuber amount of biomass of Nanyu 1 was different under different treatments. The tuber yield of Qingyu 2 was higher than Nanyu 1 in Qinghai, and with the treatment of B was highest, while under the treatment of E were lowest. The amount of biomass tuber of Qingyu 2 was also different under different treatments in Qinghai. The result was shown that the effects of the measures for cultivation on tuber yield of Helianthus Tuberosus L. in Qinghai and Xinjiang Provinces were significant.
