Fifth, the autumn pull is not timely and not in place
Fruit trees can be opened all year round, but it is best in autumn. Because the autumn pulls the back of the branch without sticking, it is easy to shape. But there are very few orchards in the autumn. The gardens that were individually pulled are not in place, but they are not pulled down, Larry is not pulled, and pulling small is not big. Improvement measures: Starting from the beginning of September, the branches will not open, and the branches and branches of the same year with a length of more than 1 meter will be pulled. The size of the opening angle of the branch should be different depending on the variety, rootstock, tree shape, branches, etc., pay attention to the operation: do not go to the sky, do not enter the ground, do not bend the bow, straight line before and after.
Six, the bag is not standardized
When I removed the bag, the author saw that some of the fruit farmers were afraid of trouble, saving money and saving the bag. In a bad climate, a good bagging fruit is not green, and the coloring is not good, that is, it forms a sunburn and becomes a "defective". The correct method is: choose from 8:00 am on the cloudy day to the end of about 5 pm, and the time for clearing the bag is 8-11:30, and 3:7-7 pm is appropriate. When operating, first tear off the outer paper bag, and then remove the inner bag after 3 sunny days. And pay attention to the weather changes, avoid unpacking in the hot sun and rainy days, so as not to affect the quality of the fruit.
Seven, picking leaves and turning fruit into a small number
Picking leaves and turning fruit is a practical technique to improve apple commodity rate and fine fruit, but this technology has not received much attention in most fruit farmers in fruit areas. It is always troublesome to do so, so that many good apples are only shaded by a petiole, a small branch or less than half of the leaves, causing the fruit to not be fully colored. Specific measures: 15-20 days before fruit ripening (after bagging fruit removal), remove the shading leaves and fruit leaves in the upper part of the fruit, pay attention to retain the petiole; when the fruit sun surface reaches the color tone of the variety, use Gently hold the fruit and turn the sun to the shade to make it fully colored.
To be careful of:
1. picking leaves and turning fruit should be selected in cloudy or cloudy weather; should not be carried out at noon in the hot sun.
2. the degree of leaf picking should be controlled moderately, otherwise it will affect photosynthetic efficiency and nutrient accumulation.
Eight, no matter after picking the fruit
For the orchard after fruit picking, pruning and spraying, some fruit farmers think that this is an extra move. Neither spray or leaf, nor tree treatment. It should be said that this is not right.
Do a good job of four things:
1. Spraying, spraying fertilizer, killing pests and diseases, supplementing nutrition;
2. Weeding, weeding, reducing the number of pests and diseases;
3. soothe the branches, adjust the light, strong body strong branches;
4. check rot, apply pharmacy, rehabilitation tree
