沙田柚由于其固有的特性,需要通过异花授粉才能结实。而生产实践上往往因授粉期气候不同,柚树的长势各异造成授粉后使受精和座果率有很大差别,因而挂果极不平衡;有的树不挂果或挂果少,有的树或枝条挂果特别多,而挂果多的树和枝条则又需要疏果。疏下的幼果白白浪费掉。这样影响了柚果的产量和品质。为了使沙田柚树挂果既平衡且均匀,把疏果时丢弃掉的幼果充分利用起来,提高株产 Shatin pomelo due to its inherent characteristics, need cross-pollination to be strong. The production practice is often due to the pollination of different climates, the growth of pomes different pollination after fertilization and fruit set rate is very different, and thus fruit is extremely unbalanced; some trees are not fruit or fruiting little, and some trees or Branches particularly large number of fruiting, and fruiting trees and branches need to be thinning fruit. Shu sparse young fruit wasted. This affects the yield and quality of pomelo fruit. In order to make Shatian pomelo fruit tree is balanced and even, to discard fruitless fruits in full utilization, improve plant production
