Sunshine rose at present most people have done the expansion treatment, but the effect has its own advantages, some expansion is ideal, the expansion of about 7 days of fruit and thumb as big, but some of the swelling consequences do not see the long, here a few reasons, just ask yourself how many?
First, the first thing to say is that the most decisive factor in the size of the fruit is related to the tree potential, the tree is weak and doomed to have no good fruit, no large fruit, and it is easy to burn in the later stage. Therefore, for those who have just planted seedlings, we must raise seedlings well, and a good tree determines half of the success.
Second, is there any neglect of flowers before flowers? The biggest consequence of not neglecting flowers before flowering is that the flowering period is inconsistent, resulting in difficult fruit preservation, and even easy to appear large and small fruits and zombie fruits. Talking about this year's problems, many parks this year have had difficulties in fruit preservation, and there are many zombies. The main reason is that the temperature is unstable this year, and there was a lot of rain in the early stage. So don't doubt your own treatment agent problem.
Third, did not play a single layer in time, did not timely thin the fruit, in recent years, labor difficulties, for the park with labor difficulties, in the case of insufficient manpower, first hit the single layer and then thin the fruit, do not underestimate the single layer, the single layer can have a better spike type, and it is easier to make the bottom of the fruit grow evenly.
Fourth, fruit thinning, fruit thinning conditions are best to be finished within 5 days, the large park may not be able to do it, but the problem of the small park must be solved well, early dredging of a day of fruit, the fruit can grow bigger, tree nutrition is limited, limited nutrition delivery to more than 100 fruits and 60 fruits The difference is very large, many of the large particles of the park people's fruits can grow to the size of the thumb before the expansion treatment, not bragging, you look at the large particles around you can do, Which one didn't see the prototype before it was expanded?
Expanded fruit on May 20th
Fifth, the fertilizer water is not right or the fertilizer water supply is insufficient, this has been said earlier under the fertilizer method, weak trees mostly use high nitrogen, but not all use high nitrogen, such as the early fruit preservation before and after the fruit preservation more use of high nitrogen, after expansion with high nitrogen balance alternate. Strong trees with high nitrogen and balance alternate on the line, the early balance can not be used too early, at least before the expansion can not be balanced, because the balance of potassium content is high, easy to promote premature lignification of branches, too early lignification is not conducive to the nutrient delivery of fruit.
