Autumn harvest "Autumn Lin" orchard management do not care
Recently, the country has entered the rainy autumn "Autumn" weather. It is rainy and rainy, which has caused great inconvenience to the management and harvesting of mid-late ripe fruits. Below, the orchard management techniques in rainy weather are described below.
Pay attention to drainage and flood control
Every time after the rainy weather, the fruit bag should be inspected in time, and the water in the bag should be drained in time. Otherwise, it will easily lead to serious black spot disease and red spot disease. September is the concentrated coloring period of apples. Appropriate control of water supply is conducive to the coloration of fruits and improve the appearance quality.
Strengthen cultivating loose soil
At present, there is more rain, the soil moisture is too large, the ventilation is poor, and the death of the root suffocation is serious, which often leads to browning of the leaves. The arable soil of the orchard should be strengthened to keep the soil loose and well ventilated, creating a good soil environment for root growth and development.
Trimming dimming in time
1. Remove the roots and sprouts; 2. Remove the strong branches, dense branches and peripheral branches of the main branches. 3. The opposite side of the branches is softened and pressed to the sides to grow horizontally. ; 4. Cut off the autumn shoots on some of the developmental branches; 5. For the larger branches that grow upwards, pull the branches and open the corners to improve the scenery conditions, reduce the nutrient inefficient consumption, and promote nutrient accumulation.
Do a good job of nutrient supply
1. The application of basic fertilizer should pay attention to time, rationality and scientificity. The specific requirements are: the best fertilization time is from September to October; the fertilizer type is mainly organic fertilizer, the application of bio-organic fertilizer, the application of chemical fertilizer and the supplement of micro-fertilizer. The depth of fertilization is 20-40 cm (concentrated layer of roots); it is recommended to supplement the roots before harvesting, supplementing the problem of insufficient nutrient supply due to excessive rain and excessive soil nutrient loss to promote rapid fruit development.
Pest Control
1. Grasp the time to spray a high-quality fungicide insecticide to prevent spotted leaf disease and ring-shaped fruit disease, gold-grained moth, apple aphid and so on. 2. After unpacking, quickly spray 600-800 times of high-quality liquid + 2000-2500 times of heavy calcium to protect the fruit and prevent the occurrence of red dot disease. It also has a good effect on promoting the development of fruit color.
Take off the bag, turn the fruit and lay the reflective film
The bagging time should be sunny, and it is sunny in 3 to 5 days. It is best to take off the bag at 8:00 am to 12:00 am and 2:30 pm to the time before the sunset. The result is to rotate the fruit by 90 to 180 degrees, so that the yin and yang faces of the fruit are exchanged to ensure that the original yin is also lascivious. The reflective film is applied after the end of the picking. A reflective film is placed under the canopy to reflect the light that hits the ground to the tree, so that the scorpion fruit and the scorpion of the fruit are also colored.
