摘　　要：针对5年生以上脐橙“小老树”低产园,探索种植绿肥开沟深压改良土壤的技术措施,结果表明:连续3 a通过间种绿肥、开沟深压、基肥深施、深翻园土等技术措施,试验园脐橙的产量达到1503.18~1615.95 kg/667m^2,产值为7515.90~8079.75元/667m^2,纯收入达到4632.90~5196.75元/667m^2,比对照增加3295.25和3859.10元/667m^2,经济效益显著;同时,果实品质和商品率逐年得到提升,2018年果实商品率达到91.78%~92.16%。Considering the issue of low yield orchards with over 5-year-old stunted navel orange trees,we have explored a series of measures to improve soil conditions.The results showed that through the combined application of soil improvement techniques such as interplanting green manure,ditching and deep pressing,deep application of base fertilizer,and deep plowing of orchard soil for 3 consecutive years in the tested navel orange orchard,the fruit yield reached 22547.7-24239.25 kg/hm^2,the output value was 112738.5-121196.25 yuan/hm^2,the net income was 69493.5-77951.25 yuan/hm^2,increased by 49428.75 yuan and 57886.5 yuan per hectare,respectively compared with the control,and the economic benefits were significant.Meanwhile,the fruit quality and commodity rate were improved year by year,and the fruit commodity rate reached 91.78%-92.16%in 2018.
