First, postpartum fertilization Why do you want post-fertilization? Because the fruit trees undergo germination, flowering, and fruiting in a year, the fruit is harvested. The tree that picks the fruit is like the mother who gave birth to the child. The body is very weak. If it is not timely provided and protected, it is very easy to be invaded by germs. This fertilizer must be a quick-acting fertilizer, which can be fertilized by water-soluble fertilizer, which can make the fruit recover more quickly. The earlier this stage, the better, and it will be late after the fruit enters the dormant period. Second, the Qingyuan treatment First of all, what is Qingyuan? Why do you want to clear the garden? In fact, the Qingyuan is to clean up the dead leaves of the orchard. Take the apple tree as an example. Some of the fruits of the bark often hide many diseases, such as red spiders, star caterpillars, leaf curlers and other pests. Eggs. Many people say that returning to the roots will turn into better nutrients. In fact, sometimes it is wrong to say that it is best to do incineration, because some of the branches and leaves are diseased leaves, or diseased branches, diseased fruits, and the diseases that cause fruit trees are generally These are caused by these inconspicuous small diseased diseased branches, because many pathogens have an incubation period. It is necessary to seriously clear the garden and not cause harm. It is too late to regret it. Third, the control of pests In addition to the cut off pests, the pest larvae that have been drilled into the trunk for wintering must be removed. After all, the embankment of a thousand miles collapses in the ant nest. You can kill a variety of larvae by using cotton dampened with dichlorvos emulsifiable concentrate and 100 times of water or by mixing it into the worm's mouth. In the orchard, scrape off the cracked rough skin on the fruit tree, brush the stone sulphur mixture to brush the white trunk, and kill the eggs. For the tigers in the soil, pests such as cockroaches can burn the tea cakes to browned and smashed with fire, then soak them in four times of hot water for four hours, and then cool them and pour them into the garden to kill them. Fourth, the base fertilizer and cover grass In the early winter of the fall season, fertilization is required once again. At this time, the fruit has entered a dormant period, and it is necessary to carry out deep soiling, and one plant is applied with sufficient organic fertilizer. Because the fruit trees began to wake up before and after the horror, the roots are the first to start the activity, the roots are to promote the infusion flow to transport nutrients, the branches become soft, and the germination begins. The nutrients needed during this period are all the fertilizers stored in winter. Covering a layer of straw after applying fertilizer is conducive to water retention and fertilizer protection, and can also enhance the anti-freezing of fruit trees. In addition, you need to understand that flower bud differentiation is the result of a variety of endogenous hormone interactions, in which ethylene, abscisic acid and cytokinin promote the formation of flower bud differentiation, while auxin and gibberellin form a flower bud differentiation. It has a suppressing effect. You can spray the fruit tree 1-2 times with paclobutrazol before the new growth stops, which can promote the differentiation of the top bud into flower buds.

[Sample requirements] Vtm Sampling Tube With Swab,Disposable Collection Tube Of Virus Samples,Hi Media Vtm Kit,Amylase Sample Collection Tube Jilin Sinoscience Technology Co. LTD , https://www.jlgkscience.com
The collected nasopharyngeal swab samples should be transported at 2°C to 8°C and sent for inspection immediately, and the sample delivery and storage time should not exceed 48 hours.
[Testing method]
1. Before sampling, mark the relevant sample information on the label of the sampling tube.
2. According to different sampling requirements, use a sampling swab to sample in the nasopharynx.
3. The specific sampling methods are as follows:
a) Nasal swab: Gently insert the swab head into the nasal palate, stay for a while and then slowly turn to exit. Wipe the other nostril with another swab, immerse the swab head in the sampling solution, and discard the tail.
b) Pharyngeal swab: Wipe bilateral pharyngeal tonsils and posterior pharyngeal wall with a swab, also immerse the swab head in the sampling solution, and discard the tail.
4. Quickly put the swab into the sampling tube.
5. Break the part of the sampling swab higher than the sampling tube, and tighten the tube cover.
6. Freshly collected clinical specimens should be transported to the laboratory within 48 hours at 2°C to 8°C.
[Explanation of test results]
After the sample is collected, the sampling solution turns slightly yellow, which will not affect the nucleic acid test result.
[Limitations of the test method]
1. For samples that are seriously contaminated due to improper storage after collection, the final test results will be affected.
2. If the sample is not stored at the specified temperature, the final test result will be affected.
What should I pay attention to in winter fruit trees?
[What should I pay attention to in the winter fruit tree garden?] Nowadays, it is the season when a large number of fruits are on the market. Many orchards are busy doing the final harvesting work. In fact, in addition to harvesting, the harvesting of the orchard is also very important, and is likely to be related to next year's production. The following article introduces you to what to pay attention to in winter fruit trees.
