Can Mopan persimmon be planted in cold areas? Can it be planted in Minqin County Hospital of Gansu Province?

Mopan persimmon can't be planted in cold areas, nor can hospitals in Minqin County, Gansu Province. Panshan persimmon likes warm climate and grows well in the area with annual average temperature 10 ~ 15℃. In winter, it can tolerate the low temperature of -2 1℃, and the freezing damage begins at -22℃. The germination temperature of Panshan persimmon should be above 65438 02℃. The growth of branches and leaves should be above 65438 02.8℃; The flowering temperature should be above 65438 08℃; The fruit development period needs 2 1 ~ 26℃, and if it exceeds 30℃, the fruit quality will be affected (the surface of the fruit is thick and the taste is light). Panshan persimmon is the most suitable area for cultivation along the Great Wall and Panshan area in Jixian County, Tianjin.

Panshan persimmon has a large root system, the vertical roots of mature persimmon trees can reach more than 3 ~ 4 m, and the horizontal root system distribution is often about 3 times of the crown width. In addition, Panshan persimmon has many root hairs, strong absorption capacity and is very drought-tolerant. However, excessive drought is easy to cause falling flowers and fruits. Especially in the long-term spring drought, summer rain is abundant and concentrated, which often causes serious fruit drop and directly affects the yield and quality. The growth of persimmon shoots and fruit development need sufficient water. Water in time when there is no rain in spring drought; The rainfall in summer and autumn is large and concentrated, which makes the soil water content too much, so it must be drained in time, otherwise it will affect the formation and growth of new roots and the yield and flower bud formation in that year. Therefore, it is not suitable to plant Panshan persimmon in the plot where the groundwater level is higher than 1.5m, and water often accumulates in summer and the drainage condition is not ideal.

Air humidity also affects the growth and development of persimmon trees. If there is continuous rainy weather in flowering period and young fruit period, it is easy to drop flowers and fruits; If it happens at harvest time, it can make persimmon fruit lighter in color, lower in sugar content and lower in quality.
