The correct pronunciation of grape is pú táo.
Grape (scientific name: Vitis vinifera?L.) is a woody vine of the genus Vitis of the Vitaceae family. The branchlets are cylindrical, with longitudinal ribs, hairless or sparsely pubescent, the leaves are oval, and the inflorescences are panicles. Dense or scattered, with well-developed base branches, spherical or oval fruits, flowering period from April to May, and fruit period from August to September.
Grapes are one of the oldest fruit tree species in the world. Plant fossils of grapes were found in the Tertiary strata, indicating that they were already spread across Europe, Asia and Greenland at that time. Grapes are native to western Asia and can be found all over the world. About 95% of the world's grapes are cultivated, concentrated in the Northern Hemisphere.
Grapes are a famous fruit. They are eaten raw or made into raisins and made into wine. The lees after winemaking can improve the acidity of the wine. The roots and vines are used medicinally to stop vomiting and prevent miscarriage.
Extended information:
1. Nutritional value
Grapes are similar to most crops. There are about 17 kinds of nutrients required for their growth: carbon, hydrogen , oxygen, nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, iron, manganese, zinc, copper, boron, molybdenum, chlorine, cobalt. The carbon and oxygen in the base are obtained from carbon dioxide in the air during photosynthesis, and hydrogen comes from Most of the water and other elements in the soil, except nitrogen, are absorbed from the soil by the roots.
Their proportional relationship is: 94-99.5 of the fresh tissue of crops is composed of carbon, hydrogen and oxygen from air and water, while only about 0.5-6 is from nutrients in the soil. Chemical fertilizers mainly provide the three elements of nitrogen, phosphorus and potassium. Some chemical fertilizers also contain large amounts of calcium, magnesium and sulfur. Although the effect of using chemical fertilizers is obvious, excessive use can easily cause fertilizer damage, especially the amount of potassium fertilizer should be used carefully.
Organic fertilizers have low nutrient content, can be used in large quantities, and can improve the physical, chemical, and biological properties of the soil. In addition, soil amendments can be added depending on the soil condition. Generally speaking, strongly acidic soils are more likely to lack phosphorus, potassium, calcium, magnesium, silicon, molybdenum, zinc, copper, boron and other elements; alkaline or calcareous soils are more likely to be deficient in nitrogen. , phosphorus, iron, manganese, zinc, copper, iron and other elements.
Nutritional supplementation is mostly done in three ways: basal fertilizer, top dressing, and foliar fertilization. The basal fertilizer is used after hibernation or harvest. Top dressing is to apply chemical fertilizer after rain or watering after flowering. Dolomite powder or lime can be top applied to soil with a pH value below 6.0.
2. Distribution range
Grapes are native to western Asia and are cultivated all over the world. About 95% of the world’s grapes are concentrated in the northern hemisphere. The main producing areas in China include Xiao County in Anhui. , Turpan and Hotan in Xinjiang, Yantai in Shandong, Zhangjiakou, Xuanhua, and Changli in Hebei, Dalian, Xiongyue, and Shenyang in Liaoning, and Lumiao Township, Minquan, and Yifeng in Henan.
