Anonymous users2024-02-15It's autumn harvest season. If there is continuous rainy weather in some places, it will be quite inconvenient to manage the orchard before and after harvest. Let's learn what to look out for in rainy day orchard management and autumn harvest?
1. Pay attention to drainage and waterlogging, after the rainy season, check the fruit bag in time and drain the water in the bag in time, otherwise it is easy to cause serious blackhead disease and red head disease. September is the period of concentrated coloring of apples, and the water supply should be properly controlled to promote the coloring of fruits and improve the appearance quality.
2. At present, there is more rain in the season, the soil moisture is too high, the aeration is poor, the suffocation of the roots is more serious, and the leaves often brown and die. Cultivation in the orchard should strengthen the loose soil, keep the soil loose and well ventilated, and create a good soil environment for the growth and development of the root system.
3. Prune at the right time.
1) remove germinated tillers and tillers;
2) remove the robust branches, dense branches and peripheral multi-headed branches at the back of the main branch;
3) The contralateral branches are softer than the vigorous branches, and grow horizontally to both sides;
4) cut off part of the autumn shoots on the developed branches;
5) For the larger branches that grow upwards, open the corners to improve the landscape conditions, reduce the inefficient consumption of nutrients, and promote the accumulation of nutrients.
4. To do a good job in fertilization and basal fertilizer, we should pay attention to speed, reasonableness and science. The specific requirements are as follows: the best time for fertilization is from September to October.
The type of fertilizer is mainly organic fertilizer, adding organic organic fertilizer, appropriate application of chemical fertilizer, and supplementation of micro-fertilizer. The depth of fertilization is 20-40 cm. It is recommended to supplement fertilizer outside the roots before fruit picking to alleviate the problem of insufficient nutrients and excessive soil nutrient loss caused by excessive rainfall and promote the rapid development of fruits.
5. Pest control.
1) Do not take the time to spray high-quality fungicides and insecticides once to prevent leaf spotting and fruit rot, golden moths, flower aphids, apple cotton, etc.
2) Spray 600-800 times high raw liquid + 2000-2500 times heavy calcium solution quickly and carefully after unpacking to protect the fruit and prevent the occurrence of erythema, which also has a good effect on promoting the color development of the fruit.
6. The time for taking the bag, moving the fruit, and pasting the reflective film should be sunny, 3-5 days for sunny, and the time for taking the bag should be 8-12 hours. Morning and afternoon on the eve of sunset. Rotating the fruit is to rotate the fruit 90 to 180 degrees, so that the yin and yang sides of the fruit are interchanged, so as to ensure that the original yin side is also illuminated.
Leaves are picked and then applied reflective film. Laying a layer of reflective film under the canopy can reflect the light that hits the ground onto the tree, so that the backlight of the fruit and calyx in the inner cavity also has color.
This is the solution to the "autumn shower" encountered in the autumn harvest, and the fruit growers choose according to their own situation and needs to reduce economic losses.
