There is a certain regularity in the accumulation and consumption of nutrient material in the fruit tree, especially for deciduous fruit trees. Different fertilizers, different dosages, different use time, the effect is also quite different, which is also called "autumn application of gold, winter application of silver, spring fertilization is rotten iron."
Qiu Shiji Fertilizer is one of the most important links in the annual management of the orchard, and plays a role in linking up and down. It not only has obvious effects on rejuvenating the tree and promoting fruit expansion, but also closely related to the yield and quality of the coming year.
Promote the expansion of late-maturing varieties
After the fall, the late-maturing varieties enter the last expansion period before maturity. The expansion is mainly to increase cell fluid and sugar. If the tree is not rich in nutrients, the synthesis and transport of nutrients will be affected. In the case of potassium, potassium is involved in the activity of more than 60 enzymes in the tree. The enzyme activity is strong, the metabolism of the tree can be vigorous, and the synthesis of various organic substances can be successfully completed. The various nutrients applied by the base fertilizer in autumn are the same as the potassium elements, and each has its own function. When their effects are combined, they can promote fruit enlargement and promote fruit coloration, thereby improving fruit quality.
Increase tree nutrient accumulation
In autumn, the vegetative growth of the tree enters the lowest period of the year, and the photosynthetic capacity of the leaves is maximized throughout the year. The nutrients synthesized by the leaves are rarely used for the construction of vegetative organs such as shoot growth, and most of them are used for storage, which is used for the growth of spring trees in the coming year. It can be said that the autumn nutrient storage of the tree is to engage in "savings". The more "money" is stored, the more "rich" the fruit trees will be in the coming year, and the stronger the ability to flower and fruit. If the storage nutrients in autumn are insufficient, the tree in the coming year must be weak, the amount of fruit hanging is low, and various pests and diseases are serious. For example, rot disease and root rot are directly related to the strength of the tree. These most difficult diseases are caused by a large amount of storage nutrients.
Significant rooting
Guan Shu first takes root, this is what everyone understands, but how to root, most people are blind. In autumn, the fruit trees enter another peak of rooting. This time, the roots last longer and the roots are large. Through the autumn application of base fertilizer, moderate rooting is conducive to the healing of the root of the wound, which is beneficial to the doubling of the root coefficient. The annual physiological diseases such as yellow leaf disease and lobular disease are high in fruit trees. One of the main reasons is that the root system is poorly developed and the effective nutrients in the soil are not absorbed.
Promote further differentiation of flower buds
Flower bud differentiation of fruit trees is an ongoing process. Looking at the full buds in the fall, it is not a good flower bud in the coming year. Looking at the autumn and winter is the phenomenon that flower buds become large leaf buds in the coming year, and it is not uncommon in production. This is because flower bud differentiation is not done in one go, and there are continuous physiological and biochemical activities inside the bud. The differentiation of flower buds continues until the flowering is completed. Autumn is an important stage of flower bud differentiation. Flower bud differentiation requires fertilizer to provide energy. Therefore, the basic fertilizer can not be ignored.
