| 摘 要： | 为了探讨热带特色经济作物云南小粒咖啡的节水高效生产模式,通过3种滴灌模式(常规滴灌、交替滴灌和固定滴灌)和2个保水剂水平(有保和无保)的完全组合试验,研究灌水方式和保水剂对小粒咖啡生理生态、生物量积累及水分利用效率的影响.结果表明:与常规滴灌相比,交替滴灌和固定滴灌的叶绿素、脯氨酸、丙二醛、可溶性糖含量均大幅提高;交替滴灌的根系活力显著提高,而固定滴灌的根系活力减小.交替滴灌能使小粒咖啡减少耗水量32.07%,提高水分利用效率29.87%.施用保水剂的叶片脯氨酸、丙二醛、可溶性糖含量减小,而生物量积累和水分利用效率分别增大24.81%和33.03%.与常规滴灌不加保水剂相比,交替滴灌配施保水剂能显著提高小粒咖啡叶绿素、根系活力和可溶性糖含量,而减少丙二醛和脯氨酸累积,同时增加总生物量13.80%,提高水分利用效率73.41%.因此,交替灌溉配施保水剂是一种小粒咖啡适宜的节水综合调控措施.

| Abstract: | To explore water-saving and high-efficient production modes of featured tropical cash crop-Yunnan arabica coffee, the effects of irrigation mode and super absorbent polymer(SAP)on physiological and ecological characteristics, biomass accumulation and water use efficiency(WUE)of the arabica coffee are studied experimentally. The experiments are conducted by using three drip irrigation modes, i.e. conventional drip irrigation(CDI), alternative drip irrigation(ADI)and fixed drip irrigation(FDI), and two levels of super absorbent polymer, i.e. SAP and NSAP. The result show that ADI and FDI can increase the content of chlorophyll, proline, malonaldehyde and soluble sugar greatly compared with CDI, and ADI can extend the root activity while FDI reduces it significantly. ADI can reduce water consumption by 32.07%, increasing WUE by 29.87%. The applied SAP can reduce the contents of proline, malonaldehyde and soluble sugar in leaves, causing 24.81%, 33.03% increments respectively in the biomass accumulation and WUE. Compared with CDI plus NSAP mode, ADI plus SAP mode can enrich the content of chlorophyll, root activity and soluble sugar greatly, lower the accumulations of malonaldehyde and proline, increase the total biomass by 13.80% and improve WUE by 73.41%. Therefore, ADI plus SAP mode can be a suitable to comprehensive water saving regulation measure for Yunnan arabica coffee. |
