What is the cold resistance of Yimeng frost red peach?

The adult peach tree of Yimeng Frost Red Peach can withstand the low temperature of minus 25 degrees, so seedling raising should be considered as appropriate. The critical temperature of frost at flowering stage varies with flowering phenology. Generally speaking, with the passage of phenology, the ability to resist low temperature is weakened. When the flower buds meet the low temperature of -5.5℃ to-1.7℃ in the coloring stage, Yimeng Shuanghong peach seedlings will be frozen when they meet the low temperature of -2.8℃ to-1. 1℃ in the flowering stage and young fruit stage. Light hurts flowers and young fruits, and the yellow peach seedling wholesale base is on the verge of extinction.

Matters needing attention in maintenance of Yimeng frost red peach

The degree of freezing injury is different in winter. Peach seedlings remind that if the freezing injury is light, it will cause frostbite and freezing of flower buds; If the freezing injury is serious, the branches on the crown will be frostbitten and freeze to death several times; If the freezing damage is serious, the big branches will also be frozen, or even the whole plant will die.

Although peach seedlings like to be dry, drought and water shortage in the spring growth period, especially in the early stage of hard core and the rapid growth period of new shoots, will affect the growth and development of branches and fruits, leading to serious fruit drop. Drought and water shortage during fruit expansion will reduce metabolism, inhibit cell hypertrophy and growth, and at the same time affect the assimilation of leaves and reduce nutrient accumulation.

There is more rain in the south, and early-maturing varieties are generally not short of water. Late-maturing varieties should be properly watered according to the actual situation to promote fruit expansion. Peach trees are not suitable for rainy flowering, and sometimes they encounter continuous rainy weather in peach blossom period, which leads to serious yield reduction in that year. Peach trees are waterlogging-intolerant trees, and they are easy to die after the soil accumulates water.
