几种综合施肥措施对早熟温州蜜柑生长和产量的影响

对广西国有良丰农场十二年生早熟温州蜜柑采用几种施肥方法,比较不同施肥措施下,该地区早熟温州蜜柑各个物候期的生长发育情况和果实产量。结果表明:处理4分别在各个物候期前进行5次合理的氮、磷、钾配方施肥,明显影响果树的生长发育情况,果实成熟期相对提前;平均单果重量增加,达到125 g/个;平均单株产量明显增加,达到93.60 kg/株;平均产量最高,为73.94 t/hm~2。因此,针对该地区独特的地理气候环境,适合于该地区的合理施肥方式对于提高果树产量和增加经济收入显得尤为重要。

Effects of Fertilization Measures on Growth and Yield of Satsuma Mandarin (Citrus unshiu Marc.)

An experiment was carried out in the State-owned Liangfeng Farm of Guangxi to study the effect of several fertilization measures on the growth and yield of 12-year-old Satsuma mandarin (Citrus umhiu Marc.) in different phonological periods.The results showed that Treatment 4 (dressed 5 times with N,P and K formulated fertilizer according to the local conditions prior to each phonological period) significantly affected the growth of fruit trees of Satsuma mandarin.In Treatment 4 fruit matured relatively earlier,the average weight of single fruit increased to 125 g,the average yield per plant increased significantly,upto 93.60 kg per plant,and the average yield per ha was the highest (4929.50 kg).So,it is of particular importance to employ a reasonable fertilizer application measure in this area with special geographical and climatic conditions to increase the production and economic benefit of fruit trees.
