果旅融合是果业转型升级的有效途径,是乡村旅游和休闲农业发展的新模式,也是我国农业现代化发展的客观要求,对催生农村新产业新业态、实现生态宜居、增加农民收入具有重要的现实意义。以福建莆田万得福休闲果园为例,分析其发展优势、劣势、机遇和挑战,提出万得福休闲果园果旅融合发展的总体规划,明确园区定位(功能定位、形象定位、市场定位、游客群体定位),从经济性、生态性、便利性、景观性4个原则将园区分区规划为三大休闲带(慢生活休闲体验带、劳作科普体验带、观景运动休闲带)、七个功能区(倚翠听涛、八方迎客、都市农夫、精品果园、琳琅满枝、碧波潺涓、青青山岭),再根据各分区的景观特征与游赏功能需求,设置相应的游乐项目和设施。

采用田间试验研究在土壤重金属Cd(5.943 mg·kg-1)污染条件下,黑麦草和丛枝菌根对"德福mm-8"和"洛贝琪"2个品种番茄产量、抗性、Cd浓度的影响。结果表明,黑麦草和丛枝菌根单一或复合处理使2种番茄叶、茎、根、果实生物量(DW)和植株总生物量(DW)分别比对照增加了2.7%~16.8%、3.0%~16.8%、8.4%~31.5%、4.2%~38.4%和4.5%~36.6%,同时使2种番茄叶和根的丙二醛(MDA)含量及抗氧化酶活性(除叶中SOD含量外)降低;黑麦草和丛枝菌根单一或联合处理均减轻了Cd对番茄根尖细胞的毒害,根尖细胞均有恢复正常的趋势,其细胞较完整、细胞壁增厚,可见液泡、细胞核等细胞器。与对照相比,黑麦草或接种丛枝菌根处理使2种番茄果实、叶、茎和根的Cd浓度分别显著下降了6.9%~40.9%、5.7%~40.1%、4.6%~34.7%和9.8%~42.4%;番茄果实中Cd积累量较少,根、茎和叶为主要积累部位。2种番茄的果实Cd浓度和积累量及植株Cd总积累量表现为"洛贝琪"低于"德福mm-8"。

采用大田试验研究在重金属Cd(5.943mg/kg)污染下,黑麦草和丛枝菌根对2个品种番茄("德福mm-8"和"洛贝琪")产量,Cd质量分数以及对根际Cd形态的影响.结果表明,黑麦草和丛枝菌根单一或复合处理使2个品种番茄果实、叶、茎、根及植株总干质量不同程度增加,增幅达2.67%~38.42%;同时显著降低2个番茄品种的果实、叶、茎及根部的Cd质量分数,降幅达4.59%~42.45%.番茄叶、根和茎为Cd主要积累部位,果实中Cd积累较少."洛贝琪"表现出Cd低积累特性,其果实Cd质量分数、积累量及植株Cd总积累量均低于"德福mm-8".在Cd污染土壤上,种植番茄的同时套种黑麦草或接种丛枝菌根,可减少土壤中可交换态(EXC-Cd),碳酸盐态(CABCd),铁锰氧化态(Fe-Mn-Cd)及Cd全量,其中土壤Cd全量降幅达8.65%~23.21%("德福mm-8")和15.89%~27.52%("洛贝琪").番茄果实Cd质量分数与土壤可交换态Cd,铁锰氧化态Cd质量分数之间呈显著正相关性关系(p<0.05).接种丛枝菌根能促进黑麦草的生长及其对Cd的吸收,黑麦草地上部及总生物量、黑麦草Cd质量分数及Cd积累量均显著增加,分析番茄Cd质量分数与黑麦草Cd质量分数,二者呈显著负相关性(p<0.05).

Two years of eddy covariance measurements of above- and below-canopy carbon fluxes and static opaque chamber and gas chromatography technique measurements of soil respiration for three treatments (bare soil, soil+litterfall, soil+litterfall+seedling) were carried out in a tropical seasonal rain forest. In addition, data of photosynthesis of dominant tree species and seedlings, leaf area index, litter production and decomposing speed, soil moisture, soil temperature and photosynthetic photon flux density within the forest were all measured concurrently. Data from January 2003 to December 2004 are used to present annual variability of carbon flux and relationships between carbon flux and impact factors. The results show that carbon flux of this forest presented unusual tendency of annual variation; above-canopy carbon fluxes were negative in the dry season (November-April) and mainly positive in the rainy season, but overall the forest is a carbon sink. Carbon flux has obviously diurnal variation in this tropical seasonal rain forest. Above-canopy carbon fluxes were negative in the daytime and absolute values were larger in the dry season than that in the rainy season, causing the forest to act as a carbon sink; at night, carbon fluxes were mainly positive, causing the forest to act as a carbon source. Dominant tree species have greater photosynthesis capability than that of seedlings, which have a great effect on above-canopy carbon flux. There was a significant correlation between above-canopy carbon flux and rate of photosynthesis of tree species. There was also a significant correlation between above-canopy carbon flux and rate of photosynthesis of seedlings; however, the below-canopy carbon flux was only significantly correlated with rate of photosynthesis of seedlings during the hot-dry season. Soil respiration of the three treatments displayed a markedly seasonal dynamic; in addition, above-canopy carbon fluxes correlated well with soil respiration, litterfall
