Jiachen year - March southern citrus management technology points

The number of affected flowers decreased after navel oranges were frozen

After experiencing heavy snow and frost damage in early spring this year, citrus in many places in Hunan and Hubei Province was severely frozen, and fruit farmers also suffered greatly after the snow in many places. Of course, God has also given special care to Fujian Province, most of the orchards after the snow, the next day the temperature is very fast, there is no recurrence of low temperature frost damage, snow shake and no snow shake in Fujian is not much different, for Hunan, Hubei and Jiangxi many places are very different.

After the freeze, many fruit farmers in southern Gannan said: "This year's navel oranges are not flowering, please ask the boss of the car dealership to cancel the order of 'Maybach' I ordered, and then call me Mr. Chen when the navel oranges are flowered next year."

It is expected that the production of navel oranges in 2024 will be reduced in a large area, and the impact on the south of Hunan and Hubei provinces may be reduced this year due to the impact of a small year followed by a large year and frost damage. Like everyone else, Ah Guan expects that his fruit grower friends will have a better time in 2024.

Personal prediction: citrus scab in 2024 will be much more serious than in previous years.

The above is the overall pre-assessment of the local citrus industry in 2024.

Let's talk about the key points of orange management in March 2024.

The first is to conscientiously do a good job in the application of spring fertilizer for citrus and the prevention and control of diseases and pests in early spring.

Winter fertilization is not enough, look at the early spring fruit trees at a glance. If the new shoots have whiskers to come out, it means that there are flowers and leaves, which is very good; if they are all bald flowers, you must be careful, and hurry up to chase the fertilizer to force the spring shoots out in an all-round way!

When Ah Guan visited the fruit farmers, the fruit farmers also communicated with Ah Guan, last year's spring drought, the extra early ripening citrus shoots could not be pumped out, last year Ah Guan was equipped with water and fertilizer to water the fruit farmers, the new shoots with watering fertilizer are normal, there are flowers and leaves, the fruit is large and uniform and the amount of flowers in the new year is normal, and this year will not be a small year. Confession: The right thing to do every year!

For the large and small years of mandarin, early-maturing Wenzhou mandarin and navel orange orchards; last year, there were those who followed Ah Guan to do flower promotion treatment, and this year they visited the fruit farmers, and most of them told Ah Guan: this year's treatment of flowers is normal, last year's big year, this year's probability will not reduce yield or small year. It shows that some early intervention measures are effective.

Many extra-early-maturing citrus seedlings are infected with brown spot disease, which should attract the attention and attention of the majority of fruit farmers, that is, the disease is relatively difficult to prevent and control, and the general fungicide control effect is not good; This disease is not unpreventable, only with the wrong medicine will it be unpreventable!

Let's talk about conventional pest control, pay attention to the control of flower buds maggots, thrips, leaf miners and malignant leaf insects when the flowers are white in March. If you remember to treat the red spider with a cheap and easy acaricide in March, basically there will be no outbreak of red spider at the end of March, and if you don't use the medicine to prevent it once, it is likely that there will be a big outbreak in April.

Second, the newly opened orchard species are very important to the variety.

In a newly opened orchard, planting the right variety is more important than having strong capital, and going in the right direction is more important than your diligence and bravery.

Two sentences seem simple, but it is too difficult to comprehend and do well.

No one expected that the sales of Gannan navel oranges in the winter of 2023 would face such a difficult situation, and no one expected that the final sales situation of ultra-late-maturing varieties would be so difficult and dangerous.

In Fujian Province, there are only a few varieties in which the sales situation continues to be strong, and in order to ensure the interests of fruit growers, those who want to communicate with Mr. Guan can contact them privately.

Third, in the face of difficulties, fruit farmers must strengthen their confidence and face the future.

Citrus in late 2023 will not sell well, and many fruit farmers do not want to apply fertilizer or pesticides. Ah Guan guessed that it was likely to wait until May to see that there were still a lot of fruit hanging on the tree, and then think about fertilizing and using medicine, but by then it might be completely too late.

Last year's small trees with flowering promotion treatment are a little rare this year, and the tube is enough.

Fourth, let's talk about the original intention of popularizing popular science articles.

Ah Guan only talks about technical problems and their solutions, and only hopes that the fruit farmers who read the article can predict the development of pests and diseases in advance, and make prevention and preparation in advance.

Ah Guan overheard a friend talk about an orchard he had never been to before, and said that Ah Guan used pictures of his family's orchard to illustrate the problem of fruit trees, and he felt very hurt. Ah Guan later learned that he had never been to his orchard, so there could be no picture of the fruit trees in his orchard, so the appearance of the fruit tree was very similar to the problem fruit tree, which was not Ah Guan's fault, but only showed that the problem was very common. When encountering this kind of problem, it can only be like writing a novel story: this picture is purely unintentional and quoted, if there is any similarity, please do not sit down!
