Developing and rolling out new higher-yielding strains is much easier and quicker for annual crops like wheat than for perennials such as palm trees that take time to mature and will bear fruit for many years.

Liming is a traditional and effective method to amend acid soil. Previous studies mostly focused on annual crops, but rarely on the perennial fruit trees.

施用石灰是一项传统而有效的酸性土壤改良措施，而以往的研究多集中在一年生作物上，对于多年生果树研究较少。
