The removal of residual fruits will remove all residues, sub-fruits, and fruit cracks, diseased fruits, insect pests, and stagnant fruits that have not reached the requirements of commodity fruit, so as to save tree nutrients and prevent their It is a natural carrier for the transmission of diseases such as pomegranate (fruit rot, dry rot, etc.) and insects (eg Myzus persicae, Pyricularia falciparum, Conradia powder, pomegranate velvet, etc.). In general, the above-mentioned diseases, insects, worms, worms, cracks, and nuts must be removed in early October and buried deep outside the orchard.
Removal of weeds, litter and weeds, litter and fruit droppings, and the breeding of pests. Weeds, litter and fruit must be removed from the garden, and weeds and canopies outside the crown must be removed. Branches, dry branches, delicate branches, overlapping branches, overlapping branches, damaged branches, short-falling fruiting branches, fruiting branches and leggy branches, were buried or burned outside the park.
Moderate pruning at this time of moderate pruning will not only help to restore the tree vigor, but also contribute to the accumulation of nutrients, thereby enriching flower buds and promoting the formation of flower buds, laying a good foundation for safe wintering and high yields for the following year. Pomegranate tree sprouting, branching force are strong, in the pruning method to sparse, short cut, retraction, as much as possible sparse cut; time should be mainly winter scissors, summer scissors as a supplement, while implementing pruning The three principles are as follows: thin and dense, thin and dense, and dense branches.
Pest control The main control targets for this period were peach aphid, peach borer, hook moth, golden caterpillar and other pests and diseases such as dry rot, fruit rot, and brown spot. The control method is to combine pruning and take the following measures.
1. Scrap old skin. In order to prevent the re-infestation of dry rot and other pathogens, after the pomegranate is harvested, the old skin is promptly scraped off, and 50% thiophanate-methyl 100% solution is used, and 50% eutectic WP 100 times solution can also be applied. Scrape old tree trunks to protect the trunk and prevent disease. At the same time, the scraped old skin is burned or buried.
2. Tree spray. In the mid-October after pomegranate picking, if the control of aphid and date turtle wax and pomegranate whitefly, can use 25% imidacloprid 2000 times + 20% fenvalerate (fast killing small) 2000 times liquid mixture for prevention and treatment . If locusts, dates, wax worms, pomegranate mealworms, moths, golden caterpillars and other pests together, can be used 25% imidacloprid wettable powder, 25% diflubenzuron, 20% fenpropathrin EC and water, according to 0.4: The ratio of 0.3:0.3:2000 was used for tree body spray control.
There are mainly the following parts: 1. Sampling swab with disposable sterile plastic rod/rayon head 2. Sterile sampling tube containing 3ml of virus maintenance solution (gentamicin and amphotericin B are selected to better inhibit the fungus in the sample. Avoid the human sensitization reaction that may be caused by penicillin in the traditional sampling solution.) In addition, there are additional parts such as a tongue depressor, a biosafety bag, etc. Intended to use 1. It is used for monitoring and sampling of infectious pathogenic microorganisms by disease control departments and clinical departments. It is suitable for sampling of influenza virus (common influenza, highly pathogenic avian influenza, H1N1 influenza virus, etc.), hand, foot and mouth virus and other types of viruses. It is also used for sampling of Mycoplasma, Chlamydia, Ureaplasma, etc. 2. It is used to transport nasopharyngeal swab samples or tissue samples from specific parts from the sampling site to the testing laboratory for PCR extraction and testing. 3. It is used to preserve nasopharyngeal swab samples or tissue samples from specific parts for necessary cell culture. The virus sampling tubes are loaded with infectious substances, and some are even highly pathogenic substances. Therefore, the requirements for packaging containers are very strict, and three requirements must be met at the same time: 1. The safety of transportation. Ensure that the sample does not leak during transportation. Sampling tubes that comply with WHO regulations and biosafety regulations. 2. The security of preservation. Ensure that the sample does not leak during storage. Sampling tubes that comply with WHO regulations and biosafety regulations. 3. The validity of the sample. Make sure that the sampling tube itself will not have a toxic effect on the sample.
