Pear flowers are frozen and jade-skinned, charming and colorful, which should be the embodiment of femininity; Pear, shaking off the cold, leaving green leaves, opening first and monopolizing the branches, is a high degree of unity of rigidity and softness.
Morphological characteristics of pear The trunk of pear is smooth in the young tree period. With the increase of tree age, the bark will thicken, crack or peel longitudinally. The shoots are hairless or have fine hairs, and then fall off; Branches over 2 years old are grayish yellow or even purplish brown. Winter buds are covered with tile-like scales, generally11-kloc-0/8. Flower buds are plump, brownish red or reddish brown, slightly shiny, and generally mixed buds; The leaf buds are small, sharp and brown. Simple leaves, alternate, serrated, stipules fall off early, tender leaves are green or red, and turn green after unfolding; The leaves are mostly oval or rectangular, and the petioles are different in length.
The flowers are corymbose, bisexual, and the petals are nearly round or broadly oval. Cultivars have 3-5 styles, 3-5 chambers, and each chamber has 2 ovules. Fruits are round, oblate, oval and spoon-shaped. There are two kinds of peels: yellow or brown, and some of the yellow varieties are red; The fruit stalks of Qiuzi pear and Xiyang pear are thicker and shorter, while those of Pak Lei Shali pear and Xinjiang pear are generally longer. There are stone cells in the pulp and cartilage in the endocarp; Seeds dark brown or nearly black.
Pears have been cultivated in China for more than 2,000 years, with a long history and a wide variety. Since ancient times, it has been deeply loved by people, and its elegant appearance has won the admiration of poets. Originally from China, it is cultivated all over the country. The output of pears in China is second only to that of apples.
For example, pear fruit is used to treat heat cough and sliced and applied to treat fire injury; Pour the juice for oral administration, moisten the lungs and cool the heart, relieve sores and hangover. Pear blossoms can remove black acne; Pear leaf soup is a good medicine for treating children's cold, cold and hernia, and bark can relieve symptoms such as qi stagnation and cough.
Pear is the fruit of Rosaceae, Pyrus pyrifolia, Pyrus pyrifolia, etc., which is mostly distributed in North China, Northeast China, Northwest China and the Yangtze River valley provinces. Harvest the fruits when they are ripe in August and September, and use them fresh or slice them to dry. You can soak in water with rock sugar. The main varieties are pear, pear, pear, pear and crisp pear.
Qiuzi pear is distributed in North China and Northeast provinces, and its fruit is round or oblate. Generally, the color of pears is golden yellow or warm yellow, and the inside is bright white, tender and juicy.
The ecological habits of pears are more adaptable to the external environment than apples. Cold tolerance, drought tolerance, waterlogging tolerance and salt tolerance. In areas where the lowest temperature in winter is above -25 degrees, most varieties can survive the winter safely. Developed root system, like light and temperature. It is advisable to choose gentle slope mountains with deep soil layer and good drainage, especially sandy loam mountains. The root system is developed, the vertical root depth can reach more than 2-3m, and the horizontal root is widely distributed, which is about twice the crown width. Strong sense of dryness and obvious layering. Early fruiting and long fruiting period, some varieties begin to bear fruit in 2-3 years, and the complete fruiting period can reach more than 50 years. Most varieties bloom first and then spread their leaves, and a few varieties have flowers and leaves open at the same time or spread their leaves first and then bloom. After pollen fertilization, the fruit begins to develop, the receptacle develops into pulp, the ovary develops into nucleus, and the ovule develops into seed. In the process of fruit growth and development, the early stage is mainly cell division and tissue differentiation, and the later stage is cell expansion and pulp maturity. The fruit volume growth curve is S-shaped. The root growth of pear has two growth peaks every year: the first growth peak appears when the new shoots stop growing; The second peak appeared in September-10. Under suitable conditions, pear roots can grow all year round without dormancy.
Pear trees are widely distributed, so their phenological periods are very different. As far as flowering period is concerned, Huili and pear trees in Sichuan generally bloom in the first half of February, and Yanbian in Jilin blooms in mid-May. Yali pear bloomed in Changsha, Hunan Province in early March and in Beizhen, Liaoning Province in early May, with a difference of nearly two months. Pear trees cultivated in the same area have different phenological periods due to different species and varieties. From germination to flowering, Qiuzi pear is the earliest, Pak Lei pear is a little later, Shali pear is later than Pak Lei pear, and Xiyang pear is the latest, and the variation range is about 10 day.
Pear belongs to Qiuzi pear with strong cold resistance, and most of its cultivated varieties can tolerate the low temperature of -30℃, such as Xiaoxiangshan, Mali, Balixiang and Gai Hua. The cold resistance of Pak Lei can also reach the low temperature of -23 ~-25℃. Pear trees are particularly resistant to waterlogging. According to research, they can endure 9 days in stagnant water without oxygen, second only to grapes.
The Distribution Area of Pears-Oriental Pear

A kind of western pear

The cultivation area and yield of pears in China are second only to apples. Hebei, Shandong and Liaoning provinces are the concentrated pear producing areas in China, accounting for about half of the cultivation area and 60% of the output, of which Hebei Province accounts for about 1/3 of the whole country.
The provinces with the largest pear production are Anhui, Hebei, Shandong, Liaoning, Jiangsu, Sichuan and Yunnan. The main pear producing area is Yantai, Shandong Province, and the cultivated varieties are Huangxian Changba pear, Qixia Dashuixiang pear, Laiyang ancient pear (Cili), Laixi crystal pear and Xiangshui pear. Hebei Baoding, Handan, Shijiazhuang, Xingtai and other places, the main varieties are Yali pear, Xuehuali, Round Yellow pear, Green Sydney, Red pear and so on. Anhui Dangshan and its surrounding areas are crisp pear producing areas; There are autumn Pak Lei, Yali pear and Qiuzi pear in Suizhong, Beizhen, Yixian, Jinxi and Fuxin in Liaoning Province. Gaoping, Shanxi is the only producing area of huanghuali, while Yuanping, Shanxi mainly produces huanghuali and avocado. Lanzhou, Gansu Province is famous for producing winter pears. Jinchuan Sydney and Cangxi Sydney in Sichuan; Cuiguan pears in Zhejiang, Shanghai and Fujian; Korla fragrant pear and crisp pear in Xinjiang, Xiyang pear in Yantai and Dalian and Jinmeng pear in Luoyang are also well-known at home and abroad.
