Analysis and explanation:
Because it is located in the low latitude plateau, the air is dry and thin, and the amount and heat of sunlight obtained in various places not only increase or decrease with the change of solar altitude angle, but also are affected by clouds and rain.
The average temperature of the hottest day in summer is about19 ~ 22℃; In winter, the average temperature in Leng Yue is above 6 ~ 8℃.
The annual temperature difference is generally 10 ~ 15℃, and the temperature is low in rainy days.
The daily temperature change is cool in the morning and hot in the afternoon, especially in winter and spring, and the daily temperature difference can reach 12 ~ 20℃.
Summer is affected by the southwest monsoon, which is humid and sultry with abundant precipitation.
Mid-Autumn Red Honey is a new variety with mid-late maturity and super high yield.
Distribution areas are in Hebei, Shandong, Shanghai, Jiangsu, Henan and Anhui.
Peach trees are fond of light and afraid of waterlogging, so pay attention to ridging when planting, drain water in time after rain, and the flowering period should be mainly dry weather.
Therefore, considering the high humidity in summer in this area, it is not conducive to flowering and fruiting, and it is suitable for planting early-maturing varieties, while planting middle-late-maturing varieties is not conducive to fruit setting.
Key points of cultivation of early-maturing varieties:
Proper close planting, using cylinder (trunk) shaping and pruning.
Promote control before planting in that year. Strengthen fertilizer and water management before the end of June, and control fertilizer and water after the beginning of July.
Spraying paclobutrazol 200 times 1-2 times on the leaves promoted the formation of flower buds and laid the foundation for a certain yield in the next year.
This variety has a high fruit setting rate. To form high-quality fruit, it is necessary to strictly thin the fruit and reasonably control the yield.
Excess fruit should be thinned according to the principle of 1 short fruit branches, 2-3 middle fruit branches and 4-5 long fruit branches.
Do a good job in pest control in different seasons.
