Differences Between London Plane, Chinese Parasol Tree and Paulownia - A Quick Guide to Telling Them Apart
In the vigorous development of urban greening and landscaping, identifying and selecting tree species is an important task. The London plane, paulownia and Chinese parasol tree may look like three sisters in urban landscaping, but in fact they belong to different families and genera, and differ greatly in morphology. The London plane is a large deciduous tree of the genus Platanus in the family Platanaceae. Its name comes from its leaves resembling those of the Chinese parasol tree; it was introduced from abroad in old China and was first planted in the French concession of Shanghai, hence the name "fa tong" (French plane). The London plane is actually a collective name for Platanus orientalis and Platanus acerifolia of the genus Platanus. Platanus orientalis reaches 30 m tall, with dark gray bark that peels off in thin flakes, revealing a greenish-white inner bark. Young branches are covered with yellow-brown stellate hairs. Leaves are 8 to 16 cm long and 9 to 18 cm wide, with 5 to 7 deep lobes reaching to or below the middle, the lobes narrow and long, covered with gray-yellow stellate hairs when young and later shedding. The common stalk bears spherical fruit heads 2 to 2.5 cm in diameter, with spiny styles 3 to 4 mm long; flowering in May, fruiting in September to October. Platanus acerifolia is a hybrid of Platanus orientalis and Platanus occidentalis, bred in London, England. It reaches 35 m tall, with bark peeling off in thin flakes and a pale greenish-white inner bark. Young branches and leaves are densely covered with pale brownish-yellow stellate hairs. Leaves are 10 to 24 cm long and 12 to 25 cm wide, with a flat or slightly heart-shaped base, 3 to 5 deep lobes, the middle lobe nearly equal in length and width, with entire or sparsely coarse-toothed margins. Fruit heads are about 2.5 cm in diameter, with spiny styles 2 to 3 mm long. Flowering in April to May, fruiting in September to October.

Quick-freezing method for peaches and detailed operating steps
Fruit selection: Peaches intended for quick-freezing processing should have fine flesh, few coarse fibers, good flavor, uniform size, neat fruit shape, no pests or diseases, no mechanical injury, easy pit removal (preferably freestone varieties), and resistance to browning. Harvest at slightly lower maturity; after arriving at the plant, a processing volume for 4 to 8 days can be stored. If stored in a cold storage, the processing period can be longer, but chilling injury to the peaches must be prevented. Generally, for white-fleshed peaches, Okubo is preferred, and for yellow-fleshed peaches, Albat is preferred. Cut in half and remove pit: Cut along the suture line into two halves and remove the pit, place the fruit cups

Ten observation points for sick pigs, so pig farmers can quickly identify swine diseases
At present, for rural farmers raising pigs, in terms of feeding and management, some people pour feed into the pig trough and turn around and leave, rarely paying attention to observing the pigs' growth and development or whether they show signs of illness. As a result, they do not know when a pig gets sick, and by the time the pig is down in the pen, it is too late and difficult to treat. To prevent disease before it occurs and treat it early when it does, symptoms must be discovered in time. Observation can be made from the following ten aspects. 1. Look at demeanor. Healthy pigs are spirited, with tails raised and swinging freely, while sick pigs are listless, slow to move, prefer lying still, and have drooping tails.

Act quickly on wheat pest control, wheat farmers please pay attention to prevention and treatment
The reporter learned from the Provincial Plant Protection General Station that this year the pest source base in the frequent outbreak areas of wheat blossom midge in our province has generally rebounded, with most places seeing the highest values in recent years, and the expected affected area across the province is about 4.5 million mu. Relevant experts suggest that fields where the "two periods" (the wheat heading and flowering period and the peak emergence period of adult blossom midges) overlap highly should be designated as target fields for control. The station's survey found that in the central Huaibei and along the Huai areas, which are frequent outbreak areas of wheat blossom midge, the pest population base is higher than in the same period in recent years. At present, wheat in the areas along the Huai and western Huaibei is

What do pigs eat to fatten quickly? Adding seasonings to pig feed works well
Pigs have a well-developed sense of taste, with as many as 15,000 taste cells in the oral cavity. Adding seasonings (flavoring agents) to feed can promote the secretion of the salivary glands, gastric glands and pancreas, increase feed intake, and promote growth and development. At present, the following seasonings are used more often: Sweet seasonings. Adding 0.05 g of saccharin per kg of finishing pig diet can increase the average daily gain of pigs by 6.4% and reduce feed consumption by about 5%. Adding 60 ppm of saccharin to the diet of lactating sows can prevent anorexia and excessive

Detailed Explanation of Key Points of Peach Quick-Freezing Processing Technology
(1) Process flow: raw material selection → pitting and color protection → blanching and cooling → peeling → packaging and adding sugar syrup → pre-cooling → quick freezing → frozen storage. (2) Key operating points. Raw material selection: after peaches are picked, ripe ones must be processed immediately; hard, unripe fruit must be ripened. Properly ripened peaches have bright color, rich flavor, and are easy to pit and peel. Pitting and color protection: after the raw material ripens, remove the pit with a small knife or a pitting machine, and immediately place the flesh in cold water to avoid contact with air and prevent discoloration. The pitting machine has fruit
