Abstract:

【Objective】 To study the effects of different drip irrigation amounts on the growth and development of licorice root at seedling stage in desert area. 【Methods】 On the saline soil of the meadow in southern Tianshan mountain in Xinjiang, field plot experiment was carried out with no irrigation(X0), very few amount of irrigation(X1), few amount of irrigation(X2), middle amount of irrigation(X3) and high amount of irrigation(X4) treatments. The licorice seedling emergence rate, plant height, leaf area index(LAI), above ground dry weight, root length, root diameter and root dry weight were measured. 【Results】 The different amounts of irrigation treatments significantly influenced the growth and development of licorice during seedling stage(P < 0.01). The emergence rate of licorice were shown as X2>X3>X1>X4>X0. The emergence rate of X2 was up to 89.30%, 60.00% higher than that of X0. Plant height, LAI and abovegrounddryaboveground dry weight were shown as X4>X3 >X2>X1>X0, which reached the highest in X4 treatment, 63.54 cm, 3.75 and 1 139.56 t/hm2, respectively, which were 44.53cm, 2.60 and 745.91 t/hm2 higher than that of X0. The root length and root dry weight were shown as X2>X1>X3>X4>X0. The root length and root dry weight in X2 treatment were 67.05 cm and 519.17 t/hm2, which were 37.51 cm and 332.99 t/hm2 higher than that in X0. The root diameter and root-shoot ratio were shownasshown as X1>X2>X3>X4>X0, both of which reached the maximum in the X1 treatment, 11.09 mm and 1.03, respectively, which were 7.31 mm and 0.70 higher than that of X0. 【Conclusion】 In summary, the amount of irrigation had has a significant influence on the growth and development of licorice during the seedling stage in desert areas. Thus, in the cultivation of licorice in desert areas, attention should be paid to the reasonable regulation of irrigation amount. In this research, it is suggested to regulate the drip irrigation amount within 2,500 to 5,000 m3 / hm2.

摘要:

【目的】研究不同滴灌量对荒漠地区栽培甘草苗期生长发育的影响,分析不同滴灌量影响甘草苗期生长发育的生理机制过程。【方法】以新疆昌吉州荒漠地区栽培甘草为材料,于2019年在昌吉州三坪农场进行大田试验。设X0(0 m3/hm2)、X1(2 500 m3/hm2)、X2(5 000 m3/hm2)、X3(7 500 m3/hm2)和X4(10 000 m3/hm2)等5种滴灌水平,检测并分析不同滴灌水平对甘草苗期出苗率、株高、叶面积指数(LAI)、地上部分干重、根长、根干重和根直径等生长发育指标的影响。【结果】不同缺水处理对甘草苗地上地下各指标的影响均达极显著水平(P<0.01)。甘草出苗率X2>X3>X1>X4>X0,X2出苗率最高达89.30%,比X0高出60.00%。株高、LAI和地上干重X4>X3>X2>X1>X0,在X4处理达最高,分别为63.54 cm、3.75和1 139.56 t/hm2,比X0高44.53 cm、2.60和745.91 t/hm2。根长和根干重X2>X1>X3>X4>X0,在X2处理最大,为67.05 cm和519.17 t/hm2,比X0高37.51 cm和332.99 t/hm2。根直径和根冠比X1>X2>X3>X4>X0,均在X1处理最大,分别为11.09 mm和1.03,比X0高7.31 mm和0.70。【结论】在荒漠地区滴灌栽培甘草生产中,将滴灌量控制在2 500至5 000 m3/hm2时,甘草苗期生长发育的各个指标能够达到最优值。
