Do citrus vegetables shed some red fast? Citrus red spider in what case comes quickly

The skin of citrus fruits is relatively soft, and it is easy to be damaged when picking, so you need to be careful. Citrus picking is also particular, so what are the precautions for citrus harvesting? 1. The weather should be suitable:

When picking citrus, it is not said that it can be picked at any time, it depends on the weather conditions, if the weather is bad, it will have a greater impact on the fruit trees after picking, and secondly, it is not conducive to harvesting. Rainy, windy, foggy weather when picking the risk is greater, not suitable for outdoor operation, if the dew is relatively large, need to pick a little later, wait for the dew to dry before picking, otherwise it is easy to cause fruit trees to be infected with diseases. In general, it is best to harvest in sunny or shady weather, so that in addition to convenient harvesting, it will have the least impact on the fruit trees.

2. Harvest in batches: When harvesting, you should pay attention to batches, and do not pick all the fruits at once, some may not be ripe. The first fruits to be picked are the middle and upper positions, which are generally of the best quality and can be used as high-quality varieties to seize the market.

It is better to build a ladder or something like to pick the top citrus to avoid the need to pull hard if the height is not enough, so the loss will be great. Each grade of citrus is packed separately, if a fruit tree is to be picked all the way, you can pick it from the bottom up, everyone according to the demand, as long as you pay attention to the batch. 3 Beware of Hurt Fruits:

The skin of citrus is very thin, so be careful of hurting the fruit. For safety reasons, pickers should wear gloves to avoid finger piercing or nail punctures, because citrus peels are easy to rot and are not conducive to storage and transportation. Scissors are the standard for picking, but some users for the sake of efficiency, no matter whether the fruit is good or not, it is solved with a pair of scissors, resulting in different degrees of damage to many fruits, and it is necessary to pay attention to the problem of hurting the fruit.

The harvested fruit frame should pay attention to the firmness, do not appear on the surface of the protrusion, and try to use a round one, so that it is not easy to be bruised. 4. Do a good job in fruit tree maintenance: After harvesting, it does not mean that the matter is over, and the fruit trees also need to be maintained, so that a complete harvest is over.

It is inevitable that there will be some damage during the harvesting of fruit trees, so it is necessary to carry out ** treatment for these tree species to avoid the expansion of losses. Secondly, the overall disinfection of the orchard is carried out, and there are more wounds left by cutting the fruit, and the citrus trees will be very vulnerable to the invasion of foreign germs. Finally, it is necessary to properly hydrate and fertilize some unripe fruits.

The above is the problem that needs to be paid attention to when harvesting citrus, once the citrus is damaged, it will rot quickly in a short time, and then it will spread to the surrounding fruit. Therefore, when storing, you must check more, and take out the problem directly, don't take this risk.

Now it has entered October, and most of the citrus in the region has entered the veraison period, which is a very critical stage of citrus quality, so most of the fruit growers pay special attention to the fruit at this stageThere will be no shortage of usual management measures, but in the management during this period, we may encounter some pits that we don't know, and we may fall into them if we are not careful.

When our citrus enters the veraison period, some growers will want their citrus to change veraison as soon as possible, so that they can be marketed earlier, so they will blindly choose chromogenic agents containing hormonesHowever, although these chemicals can make the fruit change color in a short time, it can also have some undesirable consequences, such as although the fruit colors very quickly, the color is ugly, and the appearance is relatively poor, which goes against our original intention.

And because the fruit turns color in a short time, the sugar in it is not enough, and it tastes particularly sour. The fruit with hormone color changing agent will be softer, and its shelf life will be shortened a lot, so it cannot withstand long-term storage and transportation. After spraying hormone-containing coloring drugs, the citrus will stay on the tree for a much shorter period of time, and if you don't have time to pick it, the citrus may fall to the ground due to overripeness, and the fruit will rot.

At this stage, we must pay attention to the prevention and control of pests and diseasesIn fact, there are still a lot of diseases and insects on citrus in October, so everyone must pay close attention. Certain pests and diseases can affect the coloring and sweetening of citrus, and these pitfalls need to be paid attention to.

Crops must grow naturally, and any factor that is considered to be harmful to human beings themselves.

If this is the case, then I think the first thing to understand is whether the fruit tree is sick.

The most important thing is to prevent pests and diseases, which is the most important.

In October, it is important to pay attention to the prevention of diseases and insects, which can affect the coloring and sweetness of citrus.

Most growers choose to spray hormones on fruits that are in the veraison period, but some pesticides are more likely to cause rot or uneven color distribution, which seriously affects the aesthetics.

It's a question that really baffles me, because I've never understood it.

Insecticide control is required.

During the growth period of citrus, spraying citrus with biogas slurry stock solution or adding a small amount of pesticide can control citrus aphids, red spiders, yellow spiders, mites, scales and other insect pests; Brushing diseased trees with biogas slurry can prevent and control citrus tree rot disease; Root irrigation with biogas slurry can prevent and control physiological diseases such as root rot, yellow leaf disease, and small leaf disease. The killing rate of red spider adults, the killing rate of eggs was 86%, and the killing rate of yellow spider was 86%.

The biogas slurry is diluted with 1 3 water, the killing rate of red spider adults is 82%, the killing rate of insect eggs is 84%, and the concentration of biogas slurry is getting higher and higher, and the insecticidal effect is better. When spraying citrus with biogas slurry, add 1000 3000 times of cypermethrin to kill insects and eggs, and the killing rate of adults and eggs can reach 100% and the drug period can last for more than 30 days.

It's xiaoqi

It's the water in the digester.

It is a very environmentally friendly insecticide.

Pests can cause fruit drop.

Vitamin C can promote wound healing, and you can eat some fruits and vegetables that are high in vitamin C. For example: oranges, kiwi, citrus, grapefruit, greens, carrots, pumpkin, sweet potatoes, etc.

**After the scab is formed, it is personally recommended to use aloe vera gel, which can speed up**healing, and gradually recover after several months of recuperation.

This will take a long time, be patient, and take your time.

Over time, it will slowly get better.

It's usually good to spend a summer.

Leaf mites prefer a dry and warm environment, and generally the first generation overwinters in the soil and hatches before attaching to grass, and then moving upwards from generation to generation.

Yes, the main reasons are soil acid-base imbalance, citrus roots can not absorb nutrients, high and low temperatures, disposable vegetables and fruits, improper medication, etc.

How to control the yellowing and defoliation of citrus trees in winter.

1.Pay attention to cold protection: the temperature in winter is relatively low, citrus is easy to be cold, especially in winter when the shoots are more likely to be frozen, at this time, you can protect against the cold by soil and mulching, and you can also spray high-purity phosphorus and potassium source reservoir on the foliar surface in advance before freezing.

2.Reasonable fertilization: after picking fruits in winter, winter fertilizer must be applied in time, winter fertilizer is mainly organic fertilizer, thick winter fertilizer is conducive to the recuperation of fruit trees, and at the same time, it can also be combined with "Ribery Yanwo microbial agent".

For trees that remain fresh, organic liquid fertilizer should be applied to the fruit trees in mid-December to supplement nutrients.

3.Prevention of pests and diseases: The main pests and diseases that are easy to cause citrus trees to lose their leaves in winter and spring are red spiders, anthracnose, and yellow spot disease, so we must pay attention to prevention at this time.

Out of the above three kinds of pests and diseases, nematode disease and huanglongbing disease trees will also cause winter leaf loss, at this time must be treated in time for different **.

4.Standardize agricultural operations: scientific and reasonable fertilization, irrigation and medication are the foundation to ensure the healthy growth of citrus trees. Whenever you find pests and diseases, don't be lucky, you must be early, otherwise it will affect the yield of the whole fruit tree.

It is best not to wipe the point, citrus spring shoots are mainly fruiting branches and vegetative branches of the year, which can provide more nutrients for citrus, although the branches and leaves are relatively short and weak compared to summer shoots and autumn shoots, but they can also play a good role in expanding the canopy, which is conducive to the growth of citrus.

If you plant citrus that is not out 5 8 times a year in Lingnan, Guinan and Yunnan and other places, please do not easily erase the spring shoots, which will be the main vegetative branches and hanging fruit branches of citrus fruit set.
