How to regulate the vegetative growth and reproductive growth of fruit trees?

The functions of different parts of the plant are divided, and the roots - absorbing water and nutrients, are transmitted through the xylem conduits to the branches and leafy parts. Leaves - Through chlorophyll photosynthesis, organic matter is transported through the screen of the phloem to the roots and fed to each other to form alternate growth of the shoot and the ground.

After understanding the above relationship, different methods should be adopted for the juvenile tree and the result tree: juvenile tree - strengthen the management of fertilizer and water, quickly expand the canopy, lay the foundation for the future yield and stable production, stop growing at each new shoot, and immediately after aging Fertilize, and quick-acting fertilizers are the main fertilizers.

Result trees - For fruit trees that have reached the age of the results, the relationship between vegetative growth and reproductive growth should be strictly controlled, that is, excessive vegetative growth should be controlled to promote the accumulation of more carbohydrates and hormones in the shoots, thereby promoting differentiation of buds and flowering. As a result, people achieve the purpose of planting fruit. You can also spray flower agents such as Hua Guo Ling.

Second, specific measures

1, reasonable adjustment of moisture

Ordinary maintenance of orchards suitable soil moisture, strict control of flower buds before the differentiation of water, which is usually the degree of "water." Prevent the withdrawal of new shoots at this stage, consume the accumulated nutrients, resulting in no flowering, no result.

2, a reasonable fertilization

Fertilizer is the most important material condition for the growth, development and flowering of fruit trees. Reasonable fertilization can promote fruit growth, flowering and fruiting.

(1) Fertilizer should be combined with organic fertilizer and chemical fertilizer. Chemical fertilizers should be reasonably matched with nitrogen, phosphorus, potassium, calcium, magnesium and other trace elements. At present, organic fertilizer is suitable for bean cakes, and fertilizers are used in combination with compound fertilizers and microbial fertilizers.

(2) Pay attention to the application of "pre-flowering fertilizer" and "post-fruit fertilizer." Most fruit trees are the result of spring flowers, so it is very important to reapply this flower before winter (because flowering and young fruit is not suitable for fertilization). The so-called "post-fruit fat" refers to applying heavy fertilizers after harvesting fruit. Because the whole process of fruit trees from the beginning of young fruit to the fruit ripening, it needs to consume a lot of nutrients, apply heavy fertilizer after picking fruit, and quickly add nutrients to restore the vigour. The strong, strong branch shoots are promoted, and most fruit trees are the result of the next year. In the remaining phases, specific conditions are shown and fertilizers are appropriate.

(3) Show the amount of fruit to be plucked, the specific situation of the tree vigor, and spray fertilizers out of the roots as an auxiliary measure.

3, soil management

The provision of grass weeds is the most original method and the most advanced and scientific method. It eliminates the weeds such as thatch and aconite, protects and grows beneficial weeds, maintains soil moisture, reduces temperature, prevents soil erosion, and accumulates organic matter. To protect beneficial organisms.

4, control of pests and diseases

The principle of prevention, prevention, and comprehensive prevention should be implemented.

5, timely harvest

Do a good job of fresh-keeping, packaging, and transportation to increase the value of the fruit.
