摘要

国内姜(姜)和姜黄(姜黄)根茎的产量正在增加。本研究的目的是比较使用不同容器体积和种植密度的这些作物的生长和根茎产量。进行了两次温室实验,每次持续28周。在实验I中,将单个生姜品种(布巴蓝)的一个发芽根茎和四个姜黄品种(夏威夷红、BKK、白芒果和黑)移植到小(1.5加仑)或大(13.3加仑)的圆形容器中。在实验II中,将两个生姜品种(布巴蓝和麦当娜)和两个姜黄品种(英迪拉黄和夏威夷红)的一个或三个发芽的根茎移植到大(13.3加仑)或中等(3.9加仑)的圆形容器中。在试验I中,随着容器体积的增加,植物生长和产量都有所增加,因为与小容器相比,两种作物在大容器中生长时产生的茎、根和根茎鲜重(FW)增加了一倍多。在试验II中,生姜的根茎产量在中等容器中比在大容器中高44%,并且容器体积不影响姜黄的产量。在实验I中,两个物种在较大容器体积中生长的植物的总干重(DW)都较高,而姜黄仅在实验II中较高。然而,与大容器相比,实验II中的生姜在培养基中的植物DW高18%。与较低密度相比,试验II中较高的密度增加了产量和每个容器的生物量产量,而与品种和容器体积无关。总体而言,由于根茎产量较高,第二次试验的每个容器的净收入高于第一次试验。在实验一中,尽管每公斤的销售价格较低,但与姜黄相比,生姜的产量较高,增加了该物种的销售收入。相比之下,与生姜相比,Expt.II中姜黄的较高产量导致了更高的销售收入和每个容器的净收入。根据我们的研究结果,在我们研究中评估的条件下,可以使用中等容器来最大限度地减少生姜和姜黄生产的材料和空间成本。

Effect of Container Volume and Planting Density on Ginger and Turmeric Growth and Yield
Domestic production of ginger (Zingiber officinale) and turmeric (Curcuma longa) rhizomes is increasing. The objective of this study was to compare growth and rhizome yield of these crops using different container volumes and planting densities. Two greenhouse experiments that lasted 28 weeks each were conducted. In Expt. I, one sprouted rhizome of a single ginger variety (Bubba Blue) and four turmeric varieties (Hawaiian Red, BKK, White Mango, and Black) were transplanted into either small (1.5 gal) or large (13.3 gal) round containers. In Expt. II, either one or three sprouted rhizomes of two ginger varieties (Bubba Blue and Madonna) and two turmeric varieties (Indira Yellow and Hawaiian Red) were transplanted into either large (13.3 gal) or medium (3.9 gal) round containers. In Expt. I, there were an increase in plant growth and yield with increasing container volume, as both crops produced more than double the shoot, root, and rhizome fresh weight (FW) when grown in large compared with small containers. In Expt. II, rhizome yield of ginger was 44% higher in medium than large containers, and container volume did not affect yield in turmeric. Total dry weight (DW) was higher in plants grown in the larger container volume in both species in Expt. I, and turmeric only in Expt. II. However, ginger in Expt. II had an 18% higher plant DW in the medium compared with the large container. The higher density in Expt. II increased yield and biomass production per container compared with the lower density, regardless of variety and container volume. Overall, net revenue per container was higher in Expt. II than Expt. I because of the higher rhizome yield. In Expt. I, the higher yield of ginger compared with turmeric increased sales revenue of this species, despite a lower sales price per kilogram. In contrast, the higher yield of turmeric in Expt. II resulted in higher sales revenue and net revenue per container compared with ginger. Based on our results, medium containers could be used to minimize material and space costs for ginger and turmeric production under the conditions evaluated in our study.
