负载量对大雅柑果实产量、品质和翌年结果的影响
Effects of fruit load on yield,quality,and fruiting in following year of Citrus reticulata Dayagan
摘要
Abstract
Citrus reticulata Dayagan plants with a crown diameter of 2.5 m and a height of 2.3 m were used to study the effects of fruit load on the fruit yield,quality and the fruiting in the following year and clarify the appropriate range of fruit load.7 levels of fruit load including 40,70,100,130,160,190,and 220 fruits per plant were set up to measure and analyze the characteristics of changes in indexes includ-ing the yield per plant,the proportion of fruit yield with different grades,fruit quality,the content of nutri-ents in the leaves,and the rate of flowering and fruiting in the following year with the changing of fruit load.The results showed that the total yield of Citrus reticulata Dayagan had a linear trend of increasing with the increase of fruit load,but the fruit size decreased.The proportion of large fruits was the highest at the low fruit load of 40 fruits per plant.The proportion of medium and large fruits was close at the fruit load of 100 fruits per plant.The proportion was in the decreasing order of medium fruits>small fruits>large fruits>others at the fruit load of 130 or more fruits per plant.The peel color became more bright and yellow,the peel thickness had a downward trend with the increase of fruit load,the edible rate and the con-tent of TSS in the fruit had a trend of first increasing and then decreasing.The fruit quality at the fruit load of 100 fruits per plant was the best,with the highest content of TSS and Vc of 13.15%and 34.88 mg/100 mL,and the solid-acid ratio of 18.87,respectively.The treatment with the second-best fruit quality was at the fruit load of 130 and 160 fruits per tree.The content of N and K in the leaves decreased with the in-crease of fruit load,while the content of P was not significantly affected.The number and the flowering rate of shoots at autumn,and the yield of fruiting in the following year decreased.The flowering rate of shoots at autumn and the yield of fruiting in the following year at the minimum fruit load(40 fruits per plant)was significantly higher than that at other fruit load.It is indicated that the best and most stable quali-ty is achieved at the fruit load of 100 fruits per plant of Citrus reticulata Dayagan under the conditions of current experiment.The quality is good and the yield is high at the fruit load of 130 to 160 fruits per plant,but the management of promoting the growth of shoots at autumn needs to be strengthened..关键词
