Comprehensive Evaluation And Study On Production Technology Of Tiancao And Hongmeiren Citrus In Quzhou

In this experiment,we cultivated three orchards of Amakusa and Red beauty in citrus research institute of Quzhou,Citrus seed market of Qujiang District and citrus farm of Longyou county,and analyzed the basic characters of soil in three orchards,Regular observation and tracking of varieties of growth,flowers,fruit and other basic conditions,obtained Amakusa,Red beauty in the Quzhou planting comprehensive evaluation.From the construction of the park,planting,soil and water management,plastic trimming,pest control and other aspects of management experience summed up the Amakusa,Red beauty high yield and stability of high quality cultivation of key technologies to further promote Amakusa,Red beauty The development of citrus in Quzhou promotes the adjustment of citrus variety structure.The results of the analysis showed that the soil organic matter in the three plots had little difference in PH value and could meet the normal growing needs of citrus.However,the soil available N and K contents in the three experimental plots were relatively deficient,and the available P content was more suitable.During the field management,some N and K fertilizers should be added.The results showed that the fruit of Amakusa was large,fruit-shaped flat spherical,orange-red with smooth fruit surface,orange flesh and high sugar content,and the fruit was storable and resistant to storage and transportation.Amakusa fruit performance than Satsuma and citrus fruit is good,anti-scab disease stronger than citrus and tangerine.Anti-ulcer disease Hu grapefruit,navel orange,anti-freezing damage than strong orange,worse than the tangerine.Resistance to high temperature and drought less than other varieties,poor soil quality,poor water conditions should not be developed.Red beauty trial in Quzhou showed six excellent characteristics: First,good merchandise,large fruit,oblate,peel orange red thin,beautiful appearance,fruit weight 150 g or so,easy to skin.Second,good quality,Red beauty orange high-sugar low-acid,succulent succulent,slag is good,no nuclear.Third,mature early,matured in late Quzhou in late October,is a precocious quality citrus varieties.Fourth,resistant storage,from late October listing,can be stored until March.Fifth,high yield,high exchange of trees is not easy to weaken,adult tree production in 3T-4T.Six is ??strong resistance,suitable for planting in areas with an annual average temperature above 16 ?,is an ideal variety of citrus north edge region.Based on the investigation of the biological characteristics of Amakusa and Red beauty orange in Quzhou area,this study summarized a set of Amakusa and Red beauty citrus cultivation techniques suitable for Quzhou area,from planting garden,planting,Water management,plastic pruning,pest control and other aspects of management experience and put forward specific measures.
