避雨栽培对红阳猕猴桃光合特性、植株生长和果实品质的影响
Effect of Rain-shelter Cultivation on Leaf Photosynthetic Characteristics,Plont Growth and Fruit Quality of Hongyang Kiwifruit
摘要
Abstract
To investigate the suitable cultivation mode of kiwifruit in Jiangxi Province,the Hongyang kiwifruit was used as the material to analyze the effect of the rain-shelter and open-field cultivation modes on the phenological period of kiwifruit,the garden microenvironment,photosynthetic capacity of leaves and fruit quality.The results showed that the phenophase of Hongyang kiwifruit under rain-shelter cultivation was earlier than that under open-field cultivation,and the fruit-setting rate was significantly increased.Moreover,the diurnal variation of temperature and humidity in rain-sheltered orchard decreased,the canopy temperature decreased by 4.1℃,and the humidity increased by 9.33 percentage points.The surface soil temperature can be reduced by 5.6℃,and soil moisture content can be increased by 2.09 percentage points.During the fruit ripening period,the leaves maintained a high net photosynthetic rate under rain-shelter cultivation,which effectively alleviated the phenomenon of photosynthetic'midday depression of photosynthesis'and promoted plant growth and fruit quality.Besides,the length,width and weight of functional leaves increased by 14.72%,26.18%and 31.38%,respectively,and the diameter and length of fruiting branches increased by 7.91%and 61.79%,respectively.The contents of dry matter,soluble solids,soluble sugar and titratable acid increased by 1.77,0.87,1.28 and 0.22 percentage points,respectively,and the vitamin C content increased by 31.08%.In summary,rain-shelter cultivation can effectively improve the growth microenvironment of Hongyang kiwifruit,advance the phenological period,optimize plant photosynthesis,and improve fruit quality.关键词
