“Okubo†peach has always been the pillar industry of Baoding Mancheng and Shunping County in Hebei Province. However, the original "cash tree" has become the "flower tree" of the present, and it is not fruitful without pollination. According to the author's practical experience of more than 40 years of working in fruit and fruit work, the main reasons for this phenomenon are:
First, long-term unilateral pursuit of the use of a large number of elements NPK, neglecting the medium and trace element fertilizer, leading to imbalance of nutrients in the soil, especially the emergence of severe symptoms of boron and molybdenum deficiency, manifested as incomplete development of embryos and ovules, leading to male sterility And female infertility, stigma is too short, closed flowers are not powder, flowers are not real.
Second, only pay attention to the yield and income of the aboveground parts, ignoring the physical and chemical properties and structural adjustment of the soil.
Third, do not distinguish the critical period of peach tree absorption of nutrients, blind fertilization, and even some people mistakenly believe that the more fertilized the better.
Fourth, do not understand the physiological characteristics of peach trees, there are phenomena of disorderly use of drugs, unreasonable use of conditioning agents.
Solution:
First, fertilization is to return the nutrients consumed in the soil. To do organic and inorganic, the size and nutrient are equal, the underground fertilization and the external fertilization are matched. According to the target yield, according to the critical period of the nutrient absorption of the peach trees, what is needed? When do you need to make up, how much to make, and overcome the bad habits of traditional fertilization and blind fertilization.
Second, implement the principle of planting land and raising land, so that the above-ground part and the underground part are equally important, protect the land resources on which we depend for survival, and implement the “fertile soil projectâ€.
3. Peach trees are perennial tree species, suitable for cultivation in high ridges, resistant to drought and fear, suitable for slightly alkaline soil with pH value of 7.1-7.5 degrees, good gas permeability and fertile soil, and require sufficient illumination and good ventilation.
4. The environment is the external condition for the growth and development of peach trees, scientific management, scientific fertilization, scientific use of medicine, to improve production, improve quality, enhance appearance, and ultimately achieve high without prejudice to the growth environment and physiological functions of peach trees. The purpose of the benefit.
Fifth, popularize scientific knowledge and believe in science. Rely on science, overcome the blind plan of chaos, arbitrarily introduce tree species, and adhere to the principles of local conditions to manage fruit trees.
