摘要
为了促使沙田柚丰产、高产,通过4组处理方式对沙田柚进行疏花疏果试验对比,结果表明:疏花疏果对沙田柚产量影响很大,单株花蕾数大于120个时,留花量越多,产量越低,果实品质越差;单株花蕾数小于60个时,留花量过少,产量也会相应降低;当单株花蕾数控制在60~120个时,落蕾率低于7.50%,坐果率高达90.83%以上,平均单果重达1.43kg,单株产量也相对较高,每株可达88.32kg,既能增加产量,同时也能提高果品质量。
In order to improve yield and quality of Shatian pomelo, four groups of treatments were compared for Shatian pomelo deblossoming and fruit thinning test. Experimental re-sults showed that deblossoming and fruit thinning had great effect on the ypomelo. When the number of buds per plant was more than 120,more preservedto lower yield and poorer quality of fruits. W h e n the number of buds per p60,the amount of flower was little,and the production reduced accordingly too. When the buds per plant were between 60 and 120, the deblossoming rate was lower tthe fruit rate was above 90. 83 % with average fruit weight of 1. #reaching 88. 32 kg. Thusit can not only increase the yield,but also improve tfruit.
