Pear trees are highly adaptable to soils and can grow and bear fruit in mountainous, hilly, sandy, lowland, saline and red soils. But the quality of the fruit is slightly different. Under general cultivation management conditions, high yields can be obtained.
Pear trees have a long life span, long economic use years, pear areas in the north and south of China, there are many large trees born in 100~150 years, and the branches and leaves are luxuriant, and the results are abundant, and some single plant yields can reach more than 1000~1500 kg. Seedling propagation mostly uses grafting method, commonly used rootstocks are pear, sorb, bean pear, and sand pear. The dwarf cultivation of pear trees is an important means of intensive cultivation of fruit trees, and in production, the better choice of dwarf anvil is Yunnan quince, which has the characteristics of high survival rate of cuttings and strong dwarf effect; The K-series rootstocks selected and bred by Chinese scientific and technological workers, such as K31.K9.K13.K21.K28, all showed dwarf or semi-dwarf characteristics, strong affinity with various varieties of pears, good grafting and healing, and rooting ability.
The vast majority of pear varieties are self-flowering and do not bear fruit, even if some varieties have a certain ability to self-pollinate, but cross-pollination can be better fruiting, so it is very necessary for pear orchards to have a well-configured pollination combination and sufficient pollination quantity. Generally, the ratio of main cultivars to pollinators is 3:1 and 4:1.
