What should I do if the autumn harvest in my orchard meets the "autumn rain"?

This is the harvest season in autumn. If there is continuous rainy weather in some places, it will be quite inconvenient for the management of orchards before and after harvest. Let's learn about the management of orchards in rainy days. What are the precautions for autumn harvest?

1, pay attention to drainage and flood prevention. After the rainy season, check the fruit bag in time and drain the water in the bag in time, otherwise it will easily lead to serious blackhead disease and red head disease. September is the period of concentrated coloring of apples. Proper control of water supply can promote fruit coloring and improve appearance quality.

2. At present, there is a lot of rain, the soil humidity is too high, the ventilation is poor, the root suction suffocation is serious, and the leaves are often yellow and dead. Orchard cultivation should strengthen loosening soil, keep soil loose and well ventilated, and create a good soil environment for root growth and development.

3, timely pruning?

(1) Removing sprouted tillers and tillers;

(2) removing thick branches, dense branches and peripheral multi-headed branches behind the main branches;

(3) The opposite branches are soft and grow horizontally to both sides; ?

(4) cutting off some autumn shoots on the developed branches; ?

(5) For the larger branches that grow upward, opening angles can improve the landscape conditions, reduce the ineffective consumption of nutrients and promote the accumulation of nutrients.

4. Pay attention to speed, rationality and science in fertilization and base fertilizer application. The specific requirements are as follows: the best fertilization time is September -65438+ 10. The main types of fertilizers are organic fertilizers, organic organic fertilizers are added, chemical fertilizers are applied appropriately, and trace fertilizers are supplemented. The fertilization depth is 20-40 cm. It is suggested that fertilizer should be added outside the roots before fruit picking, so as to alleviate the problems of insufficient nutrient supply and excessive soil nutrient loss caused by excessive rain and promote the rapid development of fruits.

5, pest control

(1) Don't spend time spraying high-quality fungicides and pesticides once to prevent leaf spot and fruit rot, golden moth, flower aphid, apple cotton, etc.

(2) After unpacking, spray 600-800 times of stock solution and 2000-2500 times of heavy calcium solution quickly and carefully to protect the fruit, prevent the occurrence of erythema, and also play a good role in promoting the development of fruit color.

6. Take the bag, turn the fruit, and stick the reflective film with plenty of sunshine for 3-5 days. Pick up the bag in 8- 12 hours. 2: 30 in the morning, before sunset. Rotating the fruit is to rotate the fruit by 90 degrees to 180 degrees, so that the yin and yang sides of the fruit can be exchanged, ensuring that the original yin side is also illuminated. Stick a reflective film on the leaves after picking. Laying a layer of reflective film under the canopy can reflect the light hitting the ground to the tree, so that the backlight of the fruit and calyx in the inner cavity can also have color.

This is the solution to the autumn harvest "autumn rain". Fruit farmers choose according to their own conditions and needs to reduce economic losses.
