What is the best time for fruit tree autumn fertilizer?

In the process of planting fruit trees, it is very important to implement the fertilizer. Some people think that the effect of winter fertilization is good. Some people think that the effect of spring fertilization is good. In fact, experienced fruit farmers say that fruit trees are the best in autumn. Because its effect is significantly higher than other seasons, and the application of autumn fertilizer is mainly based on biological fertilizer, supplemented by balanced compound fertilizer.

1. Improve soil, water and fertilizer

The biological fertilizer in autumn fertilizer not only can meet the needs of crops for various nutrients, but also can loosen the soil, improve the soil environment, retain water, protect fertilizer, and resist drought. The microorganisms in the fertilizer can also inhibit the survival and reproduction of harmful bacteria.

2. Promote root growth

The tree can cut off its roots, rotten roots and weak roots, and apply micro-organic fertilizer to promote the growth of new roots, stimulate the vitality of new roots, and cure diseases such as leaflets, yellow leaves and leaves of fruit trees.

3. Flower bud differentiation

Autumn is an important period for flower bud differentiation of fruit trees. At this time, there is no deciduous, photosynthesis is good, it is beneficial to the decomposition of microorganisms, which is conducive to the absorption of fruit trees. It has unique advantages for the germination, flowering, fruit setting, high yield and high quality of fruit trees.

4. Ability to quickly restore the tree

The quality of the tree directly affects the output next year. After harvesting the autumn fruit, the fruit tree needs a lot of nutrient supplements, just like a woman needs a lot of nutrition after giving birth. Therefore, some places are called "moon child fat". The nutrients required at this time are not only three kinds of elements such as nitrogen, phosphorus and potassium, but also trace elements such as calcium, magnesium, sulfur, copper, iron, boron, manganese, zinc and molybdenum.

5. Conducive to safe winter

Fruit trees with sufficient nutrient storage and robustness are more resistant to disease, cold and drought.

Anthocyanin

Anthocyanidin, also known as anthocyanin, is a class of water-soluble natural pigments, flavonoid compounds, widely found in plants. It is also the main coloring substance in plant petals, and most of the colorful colors of fruits, vegetables and flowers are related to it.Anthocyanins belong to the flavonoids (flavonoids) of the phenolic compounds.

Anthocyanins provide a variety of benefits to the human body. Fundamentally, anthocyanins are a powerful anti
oxidizer, which protects the body from damage caused by a harmful substance called free radicals. Anthocyanins also enhance the elasticity of blood vessels, improve the circulatory system and smoothness of the skin, inhibit inflammation and allergies, and improve the flexibility of joints.
Also used in cosmetics, such as red anthocyanins for lipstick. These commercial pigments (in addition to grape skin pigment) is a common feature of light, heat, oxygen stability, microbial stability. Generally soluble in water and ethanol, insoluble in vegetable oil.

There are over 300 different anthocyanins in nature. They come from different fruits and vegetables such as purple sweet potatoes, lingonberries, cranberries, blueberries, black goji berries, grapes, elderberries, blackcurrants, purple carrots, and red kale, ranging in color from red to blue. These anthocyanins mainly contain Delchindin, Cyanidin, Petunidin and Peonidin. Of these, blueberries contain the largest amount of anthocyanins and have the most nutritional value.
