摘要

持续的气候变化增加了一些地区的干旱次数,从而影响了农业生产。椰壳小米(印尼的Jali植物)的种植是有利可图的,因为它对干旱胁迫的适应性很强,而且它的种子对身体健康有益,有潜力用作食物。选择施用有机物质,即壳炭,在干旱胁迫下提高农业产量。因此,本研究旨在确定谷壳炭在干旱胁迫下营养期对椰壳小米生化和生理特性的影响,并确定该植物能耐受的最长浇水间隔。研究安排在三个重复的分裂地块设计中。主地块由三个浇水间隔组成(每两天、四天和六天)。子地块由三剂壳炭组成,即0 g聚乙烯袋⁻(0吨公顷⁻cco),32克塑料袋⁻cco(10吨公顷⁻和64克塑料袋⁻(20吨公顷⁻cco)。使用方差分析(ANOVA)对数据进行分析,并使用邓肯多重距离检验(DMRT)在5%的显著水平上进行测试。结果表明,壳炭能提高干旱胁迫下植物的叶绿素含量。椰壳小米在最佳剂量下(64克聚乙烯袋)可耐受的最长浇水间隔⁻cco)每四天一次。

Effects of husk charcoal and watering on the biochemical and physiological properties of coix millet (Coix lacryma jobi L.) during vegetative phase
Continuous climate change increases the number of droughts in some areas, thereby affecting agricultural production. Cultivation of coix millet (Jali plant in Indonesian) is profitable because of its high adaptability to drought stress, and its seeds have the potential to be used as food due to their benefits for body health. The application of organic matter, namely husk charcoal, was chosen to increase agricultural production under drought stress. Therefore, this study aimed to determine the effects of husk charcoal on the biochemical and physiological properties of coix millet during vegetative phase under drought stress and to determine the longest watering interval the plant can tolerate. Research was arranged in a split-plot design with three replications. The main plot consisted of three watering intervals (every two, four, and six days). The sub-plots consisted of three doses of husk charcoal, namely 0 g polybag⁻¹ (0 tons ha⁻¹), 32 g polybag⁻¹ (10 tons ha⁻¹), and 64 g polybag⁻¹ (20 tons ha⁻¹). The data were analyzed using analysis of variance (ANOVA) and tested using Duncan's Multiple Distance Test (DMRT) at a significant level of 5%. The results showed that husk charcoal could increase the chlorophyll content in plants experiencing drought stress. The longest watering interval that could be tolerated by coix millet given husk charcoal at the optimal dose (64 g polybag⁻¹) was once every four days.
