Among my small
illustrative posts, especially important during periods of heavy workload, and
in order to keep the blog active, here's one I do, almost by accident, after
finding some trees that have not been thinned.
This is just to
illustrate the importance of the work done, in case the previous post on the subject
(No. 13) was not clear.
If
the farmer dedicates many hours of work, with a high cost, is that there is a
reason.
The thinning
time varies according to the crops and varieties, depending on weather
conditions during flowering, and according to the market purpose of the
company.
Some species
self-regulate their charge very well, as is the case, for example, of cherry or
citrus, although there are some exceptional situations, others, on the
contrary, require the intervention of the farmer, as in the case of apple or
peach.
In
the later case, and with the same objective, the working time can vary from
about 100 hours to over 500 hours per hectare. It is the second biggest
activity, in time and cost, after harvest.
When
thinning is done, the fruits grow in a target of size and quality. The choice
of the intensity of work is done according to the variety, to the tree strength,
to their health status and the purpose of production and quality.
When
thinning is not done, the fruits are too numerous, too tight, do not grow,
deform, and are not of good quality.
The tree,
depending on its leaves volume, has a certain ability to produce the nutrients
necessary for the formation of the fruit and its good feeding. If fruits are
too numerous, they are fed by the same elements, because the plant can not
produce more, and the quality decreases.
It is generally
considered that a peach tree, to make a quality production, must have between
15 and 20 adult leaves per fruit.
Thinning
therefore aims to maintain this balance.
