Life habits of peaches
Peach originated in northwest China with high altitude, long and strong sunshine, and adapted to the continental climate with dry air and cold winter, so peach enjoys light, drought and cold resistance. Temperature is the most important factor affecting the distribution of peach trees. In the Shaanxi-Gansu-Ningxia region, southern Xinjiang and northeastern Jilin, when the temperature is below -23 ~-25℃ in winter, freezing injury is easy to occur, and early spring and late frost also occur from time to time. It is very important to prevent freezing and frost. In southern China, where the average temperature in winter exceeds 10℃ for three months, most varieties fall late and enter dormancy incompletely, and germinate late in the following spring, with uneven flowering and reduced yield. Attention should be paid to the chilling requirement of peach trees during cultivation. The cooling capacity of different varieties varies greatly, which is generally expressed by the accumulated temperature below 7.2℃. The chilling requirement of most varieties is 500 ~ 1000 hours. Peach trees are most afraid of waterlogging, and 24-hour flooding will cause plant death. It is ideal to choose sandy slightly acidic soil with good drainage and deep soil layer. Grafting method should be adopted for seedling breeding, and the rootstocks are peaches and peaches. Planting density should depend on soil, plastic methods and varieties. At present, due to the application of dwarfing agent paclobutrazol and various new technologies, the row spacing of plants is 3 m× 4 m, and 55 ~ 83 plants are planted per mu. Trees should be V-shaped, with double main branches or naturally happy.
