Closed apple orchards will cause orchards to be airtight, poor in light, and low in yield. At the same time, it is difficult to carry out fertilization, spraying, bagging and fruit picking in orchards. Most of the mistakes are that the main branch is too long and it is cut off. As a result, the growth of the main branch is even more stimulated, which makes the orchard more confined. Or a large number of main stems are retracted to form full sticks. Due to heavier retraction, a large number of leggy branches are formed on the stems, resulting in canopy closure, difficulty in flower formation, shifting of the resulting parts, reduced result area, and reduced yield. low quality. The correct approach is to make it clear that the fundamental reason for the closure of the orchard is that the planting density is too large. Only by changing the planting density, that is, the thinning of fruit trees, can the problem of confining the orchard be completely changed.
