腾格里沙漠腹地菊芋种植研究

Research on Planting Helianthus tuberosus Linn.in the Hinterland of the Tengger Desert

为了筛选在腾格里沙漠最适宜的菊芋品种和最佳施肥量及浇水量,对青芋系列的4个品种进行了沙漠种植,开展了N、P、K肥料单因素试验及浇水量试验,并进行不同处理下菊芋块茎产量及个数进行统计分析。结果表明:(1)4个品种以青芋3号产量最高,青芋4号产量最低;(2)滴灌模式下,随着浇水量的增加,产量呈现逐渐增加的趋势,单株产量最高的为T4处理;渗透浇水模式下,4个处理下,随着浇水量的增加,产量呈现减低的趋势;(3)以N4下的单株块茎重量最高达900g;以P6处理下的单株块茎重最大为650g;以K5的单株块茎重最大为738.33g。本研究为后续利用菊芋治理沙漠创造价值奠定了理论基础。

In order to screen the most suitable variety,fertilizer rate and water quantity of Jerusalem artichoke in Tengger Desert,four varieties of Jerusalem artichoke were used for desert planting and N,P,K fertilizer single factor test and watering test,and the tuber yield and number under different treatments were studied.The results showed that:(1) The yield of Qingyu No.3 was the highest,and that of Qingyu No.4 was the lowest.(2) Under drip irrigation mode,the yield increased gradually with the increase of watering water,and the highest yield per plant was T4 treatment,under osmotic watering mode,the yield decreased with the increase of watering quantity.(3) The tuber weight per plant under N4 reached 900 g,and the yield decreased with the increase of watering amount.Under the treatment of P6,the maximum tuber weight per plant was 650 g,and the maximum tuber weight per plant with K5 was 738.33 g.This study laid a theoretical foundation for the subsequent use of Jerusalem artichoke to control the desert to create value.
