| 摘 要： | 【目的】 研究矮壮素喷施次数对甜菜糖分积累及产量形成的影响。筛选适宜新疆南疆喀什新糖区甜菜糖分积累及产量形成的矮壮素喷施次数。【方法】 以KWS-9147甜菜品种为材料,选用矮壮素水剂(50%),采用大田随机区组设计,设置4个处理,分别在不同时间喷施矮壮素0次(CK)、1次(D1)、2次(D2)、3次(D3),研究喷施矮壮素次数对甜菜植株特性、糖分积累动态变化、糖分积累对气象因子的响应及产量形成的影响。【结果】 喷施矮壮素3次(D3)、2次(D2)处理与CK处理相比,使甜菜株高和枯叶数分别降低19.77%、11.24%,17.52%、17.44%;根长及根直径分别增长26.37%、19.90%,10.37%、5.93%;且使甜菜单根重和含糖率分别增加16.54%、13.38%,6.60%和5.95%,甜菜产量增产率及产糖量增产率分别达到12.69%、8.90%,20.17%和15.35%。D2、D3处理间差异不显著(P>0.05),其D2处理糖分积累动态变化与当地积温及日均温动态变化吻合度最高,拟合值分别为0.985 4、0.898 6。【结论】 喷施矮壮素2次(D2)处理有效促进南疆喀什新糖区甜菜含糖量和较高产糖量的形成。

| Abstract: | 【Objective】 To select the suitable application times of chlorpromazine for beet sugar accumulation and yield formation.【Methods】 The KWS-9147 sugar beet variety was used as the test material, and a quanquat solution (50%) was selected. The field random design was used, and 4 treatments were set, and the quanquat was sprayed 0 times (CK) and once at different times. (D1), 2 times (D2), and 3 times (D3). The effects of spraying chlormequat on the characteristics of sugar beet plants, dynamic changes of sugar accumulation, sugar accumulation response to meteorological factors, and yield formation were studied.【Results】 Spraying chlormequat 3 (D3) and 2 (D2) treatments reduced the beet plant height and dead leaf number by 19.77%, 11.24%, 17.52%, and 17.44%, respectively, compared to CK treatment; root length and root diameter increased 26.37%, 19.90%, 10.37%, 5.93% respectively; and the sweet menu root weight and sugar content increased by 16.54%, 13.38%, 6.60%, and 5.95%, respectively, so that the yield of sugar beet and the yield of sugar increased respectively. It reached 12.69%, 8.90%, 20.17% and 15.35%. There was no significant difference between D2 and D3 treatments (P> 0.05). The dynamic changes of sugar accumulation in D2 treatment coincided with the dynamic changes of local accumulated temperature and daily average temperature, and the fitted values were 0.985,4 and 0.898,6, respectively.【Conclusion】 Two times of treatment (D2) effectively promoted the formation of sugar content and relatively high sugar content in sugar beet in Kashi, southern Xinjiang. |
