At present, the production of high quality and large fruit by Red Fuji Apple has become an inevitable trend to adapt to market development and increase economic efficiency.
First, look at the appearance of the prediction of fruit size. Observations in recent years have confirmed that the top fruit of the fruit is prominent, and the angular fruits can develop into large fruit, and the axils are shallow and flat. The fruits without edges can only develop into small fruit. Fruits with long fruit shape, thick long stems, and deep stems and pits develop into large fruit. Therefore, the fruit should be left with more pods, ribs, longer fruit shapes, thicker fruit pods and deeper dents.
Second, if you want to produce more than 250g fruits, you need to leave fruit at a ratio of 1:40 to 50. If you do not reach this ratio, it will be difficult to grow large fruit.
Third, due to the lower part of the fruit of the branches and leaves less than 6 large leaves of the short branches without leaving fruit; thin and thin branches without leaving fruit; branches may occur on the branches of fruit grinding does not stay; buds on the buds of fruit does not stay; no fruit As far as possible, Taiwan's auxiliary shoots will not leave fruit; they will leave more fruit on the branches and branches.
Fourth, if the production and fruiting is calculated according to each fruit 250g, 666.7m2 (1 acre) yield 3750kg calculation, fruit tree fruit 666.7m2 amount of fruit should not exceed 15,000, the amount of high-grade fruit must be reduced, 666.7m2 can not More than 12,000.
Fifth, do not leave double-bundle Usually stay double-big and big and small, so generally do not leave double fruit, moderate tree can be a 20~25cm left a fruit.
Sixthly, removing pests and fruits to eliminate pests and fruit and rough skin can reduce nutrient consumption and ensure nutrient supply of high-quality and large fruit.
VII. Strict fruit thinning time In the inflorescence separation period, on the basis of clearing the flowers on the side flowers, squid flowers, weak branches, and peripheral branches, one week from the week after flower closure and stalk snaking are completed, to save Nutrition, concentrated nutrition.
