Is ginkgo tree cold-resistant? Ginkgo tree is a deciduous tree of Ginkgo family. The varieties are roughly Dongting Yellow, Little Fingered Citron, Unintentional Ginkgo and so on. The seeds are oblate, round and full at the top and flat and slightly concave at the base. It is produced in Dongting Mountain in Suzhou, Jiangsu, China.
Ginkgo trees can be cold-resistant and can withstand temperatures of MINUS 60 degrees. Will ginkgo trees freeze to death in winter? Ginkgo trees are generally not afraid of freezing in winter, and generally do not need special protection in cold winter, but if they are newly transplanted ginkgo trees, they should be well protected against cold and freezing, otherwise they will easily freeze to death.
Ginkgo biloba is a warm temperate subtropical tree species, which is suitable for growing in places where the annual average temperature is 12- 18℃, the monthly average temperature of 65438+ 10 is higher than -4℃, the absolute minimum temperature is -25℃, the July average temperature is not more than 38℃, and the absolute maximum temperature is not more than 40℃. It is a light-loving tree species and needs strong light to meet its photosynthesis needs. The yield of Ginkgo biloba depends on photosynthetic area, photosynthetic intensity, photosynthetic time, consumption and distribution of photosynthetic products.
Ginkgo tree has developed root system and strong drought resistance. In areas where the annual rainfall is about 1 000 mm, irrigation is generally not needed, and special attention should be paid to drainage and waterlogging prevention in rainy season. It has certain ecological adaptability to parent rock, soil texture and pH value, but it requires deep, loose, moist and fertile sandy loam and loam. Under this soil condition, Ginkgo biloba grows fast, with high yield, large seed core and long tree age.
How to manage ginkgo trees in winter mainly focuses on four aspects:
The first is water resources management.
At present, ginkgo trees are dormant. If the weather is dry, water them once.
The second is soil management.
At present, it is fertilizer management, and the amount of fertilizer applied in winter accounts for 40%-60% of the annual amount of fertilizer applied. The variety of fertilizer is mainly organic fertilizer, and the method is annular and radial fertilization.
The third aspect, plastic trimming.
For big trees, it is mainly to repair overlapping branches, cross branches and pest branches. For young trees, three or four main branches should be used for shaping; In order to keep the crown clean and tidy and reduce nutrient loss.
Fourth, paint the wall to prevent insects.
Painting can not only keep warm, but also remove germs and eggs and reduce the incidence of spring seedlings.
