一、果树挤占粮棉用地 粮食、棉花等和果树相比是浅根性作物,必须种在肥沃的地块上才能丰产。况且山区、丘陵区光照充足、温差大,更有利于果树的生长发育,果实品质比平川果园含糖量高,着色好,耐贮运,品质优。所以对经济效益不高的果园应及时退果还田。 First, fruit trees occupy grain and cotton land, cotton and other trees are shallow-rooted crops, must be planted in the fertile plots to high yield. Moreover, mountainous and hilly areas have sufficient light and large temperature difference, which is more conducive to the growth and development of fruit trees. The fruit quality is higher than that of the plain orchard and has good coloring, storage and transportation, and good quality. Therefore, the orchard with low economic benefits should be set off in time.
