水肥耦合对树莓光合特性和果实品质的影响
Effects on the Photosynthetic Characteristics and the Quality of the Raspberry Fruit Under the Water-Fertilizer Coupling
摘要
Abstract
Based on anti-canopy and measured pit facilities in the field,influences of different water and fertilizer coupling on the photosynthetic characteristic and the quality of the raspberry fruit was studied.The results show that: When the soil moisture was moderate,the Pn and Ci of raspberry leaf were increased by adding appropriate amount of fertilizer,and control the fertilizer applied could effectively reduce the Tr;when the fertilizer was moderate,the Pn,Gs and Ci of raspberry leaf were increased by adding appropriate amount of soil moisture,but not conducive to control the reduction of Tr.If the fertilization levels were under the same condition,moderate soil moisture was conducive to the accumulation of organic acids,soluble sugars and SOD nutrients in the raspberry fruit,and sufficient soil moisture were conducive to the accumulation of soluble solid and Vc content.If the lower control limit of the soil water content equaled 32% and the fertilizer reached 460.95 kg/hm2,it was beneficial to improve the Pn,Gs and shortened the time of midday depression middle level;if the lower control limit of the soil water content equaled 26.2% and the fertilizer reached 270 kg/hm2,it was beneficial to decrease the Tr of raspberry and improve the quality of raspberry fruit.关键词
