Perennial deciduous trees of winter genus are adaptable and resistant to extensive management. They belong to the family of hi-light hi-light species. The pH value is between 6.5 and 7.5 , and the fruit matures from the end of October to the beginning of November . Resistant to storage. Most of the other fruits have been harvested at maturity, just filling the gap in the winter without fresh fruit.
Â
There are more than 6,000 mu of winter peaches in Midu County , mainly distributed in towns and towns such as Lili Town and Miyu Town. Most of them have entered the fruit-bearing period, with an output value of 5000-12000 yuan per mu , which has become a new agricultural industry in the region. Grasping the management work of winter peach orchard in autumn and winter is of great significance for restoring the tree potential, ensuring the robust growth of winter peach trees and stabilizing the annual output. Combining the management of the winter peach garden in Midu County, the following management techniques are proposed:
Â
　　 1. Apply base fertilizer. The application can be started in October , depending on the size of the tree and the growth results. Generally, the high-quality decomposed farmyard manure is 2000-3000 kg, the calcium is 100-150 kg, and the borax is 3-5 kg.
Â
Fertilization method: the saplings should be applied in a circular ditch, that is, a deep and wide 40 × 40 cm fertilization ditch beside the canopy of the canopy , and the soil should be covered after fertilization; the large tree should be applied by the radiation ditch, with the trunk as the center and away from the trunk. Dig 4 - 8 radiation ditch outside 50 cm, cover the soil after fertilization. It can also be applied in the whole garden, combined with the deep turning of the orchard.
Â
　　 2. The orchard is turned over and changed to soil. Combined with the application of base fertilizer to deepen the soil, the depth is 30-40 cm. When the orchard soil is wet, the weeds are turned over to increase the soil organic matter, ripen and fertilize the soil, and promote root growth.
Â
　　 3. Reasonable intercropping. Planting dwarf legumes (such as peas, broad beans), vegetables, and green manure (such as alfalfa seeds), etc., should not plant large crops such as wheat and wheat.
Â
　　 4. Pick up the bag and drink the fruit. The winter peaches that have been placed in the fruit are removed from the fruit bag about 20 days before the fruit picking, and the fruit is dried to increase the coloring and sweetness and improve the fruit quality.
Â
　　 5. Scrape the old skin of the trunk. The peach bark, the peach heartworm, the star caterpillar, etc. use the bark as a wintering place. Therefore, in the autumn, the old skin should be scraped off in time, and the orchard burned out, which can reduce the wintering base of pests and diseases.
Â
　　 6. Qingyuan. After the leaves are fallen, the leaves, dead branches and fruit bags of the orchard are cleaned in time, the dead fruits are removed, the weeds around the orchard are removed, and the grass is burned down to reduce the number of pests. Use lime and stone sulphur mixture residue to form a whitening agent to whiten the branches to reduce sunburn and freezing damage.
Â
　　 7. Fruit harvesting. After the fruit is ripe, it will be harvested in batches in time , lightly handled, to avoid rubbing off the fruit powder. Grading, packaging, and sales. Any pesticides are banned 15 days before harvesting .
Â
　　 8. Pest control: After fruit picking, spray with 50% dichlorvos emulsifiable concentrate 800 times to control aphids, red spiders, star caterpillars, and peaches. The sunflower leaves are sprayed with 50% carbendazim WP 500-600 times or 70% thiophanate-methyl WP 800 times to make it fall normally.
Â
　　 9. Plastic pruning: After the winter peach deciduous sleep, the best time is after the winter solstice - the end of the first 10 days of the spring , easy to flow glue too early, too late to cause injury, will weaken the tree.
Â
The tree shape adopts three main branches and is naturally happy, with a dry height of 50-55 cm. First, cut off the diseased branches, over-twigs, etc., and short-cut the backbone branches to expand the canopy; use the sputum, retraction and other culture results to update the branches. Order: from top to bottom, from inside to outside. After pruning, timely cut down the branches and leaves the floor sweep, Taoyuan away, concentrated fire; Orchard spraying a 3--5 Baume lime sulfur (lime: Sulfur powder: water = 1: 2: 10 ) Carry out clearing gardens to reduce wintering pests and diseases and reduce the number of pests and diseases.

Stop Valves are closed by screwing a rubber gasket down onto a seat in the middle of the valve. Pros only use small versions that act as shutoff valves for fixtures such as sinks and toilets and outdoor sillcocks. Flow is inefficient because of the circuitous route the fluid (water, in most cases) has to follow. It's important to orient the valve in the right direction with the arrow (cast into the side of the valve) aligned with flow direction. That way, water flows against the bottom of the rubber gasket. If the valve is put in backward, the flow will force the gasket away from the top of the valve.
