摘要
为提高榕江县低产脐橙果园产量,连续三年对榕江县高接换种纽荷尔脐橙果园进行垦复施肥。研究结果表明,每年对高接换种纽荷尔脐橙果园进行垦复施肥,可以显著增加纽荷尔脐橙树的冠幅和果实产量,尤以第三年最为明显,其冠幅是对照的1.90倍,单株挂果数较对照增加27个,提高32%,产量比对照提高369㎏/667m2,增加了27%。可见垦复施肥是一项改造脐橙低产果园的重要措施,值得推广。
To improve the yield of NewhaU navel orange orchards in Rongjiang county, reclaiming fertil- ization measure was taken in continual 3 years. The results showed that the crown diameter and fruit yield were increased apparently as compared to the control. The most significant effect was observed in the third year, with the crown diameter, quantity of fruit, and yield increased by 90%, 32%, and 27%, respectively. Thus, the method of reclaiming fertilization is an important countermeasure for improving the low-yield or- chard of Newhall navel orange, being worth to extend vigorously.
