Trees are like people, the one with full nutrition will be spiritually high, resplendent and conduct high yield while the one lacked of nutrition will be spiritually low, with dim color and not even in receive and output. So, in the period of applying fertilizer, farmers must carefully cultivate and adjust agents according to true situation of soil granular structure and value the life of trees.

1. Do not apply fertilizer at any time you want when issues come out

The growth of trees is just like natural phenomenon, germinate in spring, grow in summer, harvest in autumn, store in winter. Some fruit farmer do not apply as the required time, but apply with their own feelings, labor situation and whether busy or not. “No time to apply when is needed while so much time to apply but is not needed anymore”, this finally lead to disorder of trees growth and nutrition, strong leaves but weak bodies, forming so many physiological fruit drop and do not color when coloring. Missing the best applying time will greatly discount the yield amount.

2.It not true that the more fertilizer, the better effect, the application should be based on the soil and actual conditions of the fruit trees in your own orchard

Fertilization needs to be determined based on comprehensive factors such as the plot, strength and size of fruit trees, yield, fertilizer type, and soil fertility conditions. Blindly applying too much fertilizer within a certain range can cause root and seedling burning, which not only wastes money and make soil compaction, but also burns and kills fruit trees, resulting in reduced yield. So scientific fertilization is necessary.

3、 The nutrition of fruit trees is not only nitrogen, phosphorus, and potassium but also other elements

Many fruit farmers buy hearsay of nitrogen, phosphorus, and potassium compound fertilizers or single organic fertilizers, and once applied and watered, everything will be fine. Little did they know that forming a fruit requires not only three major elements, but also a certain amount of various elements such as calcium, magnesium, sulfur, boron, silicon, iron, zinc, etc. When fruit trees suffer from yellow leaf disease, small leaf disease, black spot disease, rot disease, and low yield, they can only be helpless.

4、 It is necessary to apply fertilizers scientifically according to the growth and nutritional period of fruit trees

September to November is the peak period of fertilizer and water demand for fruit trees throughout the year. Firstly, it is necessary to expand the fruit; secondly, it is necessary to enhance its color; thirdly, it is necessary to provide the necessary nutrients for flower-bud differentiation; fourthly, it is necessary to store nutrients for the bark, xylem, roots, branches, and leaf flower buds to provide various nutrients. But many fruit farmers are afraid of dropping a small amount of fruit at this time and do not fertilize or water them. They are eager to cherish the fruit, and most fruit farmers throw away the golden fertilization period and push it to November or even February or March of the next year. According to practical calculations, fertilization at the end of September and October accounts for 80% to 85% of the total nutrient storage in the tree body. Fertilization at the end of November and December, due to low temperatures, causes the root system of the tree to stop growing and the absorption rate to decrease. At this time, fertilization utilizes only 65% to 70% of the stored nutrients in various parts of the fruit tree body, especially phosphorus, which is more fixed. Nitrogen utilization rate is relatively low due to low temperatures. Not fertilizing in a timely manner due to fear of knocking off a few fruits is a small loss, which affects the yield of the following year.

5、 Autumn fertilizer is very important

Many fruit farmers are afraid that fertilizing in autumn will cost them money, and when the "late frost" freezes in March or April of the following year, it will be all in vain. Therefore, they intentionally do not fertilize. They wait until the next spring when the flowers are warm and the fruits are "sitting" down before fertilizing and watering in large quantities. As a result, the trees and flower buds store less nutrients in autumn, and the freezing damage is exacerbated when the late frost invades. The result of this kind of work goes against the growth and development laws of fruit trees, causing the trees to become weak and artificially leading to fruit drop, reduced yield, and a decrease in high-quality fruits. There are products without commodities, let alone fine ones, and some even have half a tree of flowers and half a tree of fruits, causing many unnecessary losses to the growth and physiology of fruit trees.

6、 There should be scientific fertilization methods

Many fruit farmers are afraid that the fertilizer will not be absorbed by the roots, so they try to apply it as close as possible to the roots, less than 20 centimeters away from the trunk. In some cases, they even apply it to the roots of the trunk. As a result, due to too close and concentrated fertilization, the edges of the fruit tree leaves dry up after a few months, and the leaves turn yellow and fall off. Finally, the tree is burned to death, having great loss finally. The agricultural proverb goes, “ It's better to let the roots search for fertilizer than to let the fertilizer search for the roots.” This is to prevent fertilizing too closely and damaging the roots. Fertilization is best applied in shaded areas of tree tops.

7、 Be cautious when using farm manure

Many fruit farmers do not apply fertilizer to determine yield, or use yield to determine fertilizer for scientific fertilization. Instead, they apply large amounts of fertilizer in big harvest year and small amounts in small harvest year, and do not apply fertilizer until there are no fruits; Some wanted to make it simple, treat the big harvest year, small harvest year, strong, and weak trees all the same. The result is aimless, with excessive yield in the big harvest year and bold growth of trees in the small harvest year.

Most fruit farmers know of underground fertilization, but they underestimate or do not have a clear understanding of the role of applying foliar fertilizer, which leads to serious physiological diseases such as yellow leaf disease, small leaf disease, fruit shrinkage disease, and early leaf fall disease, and a decrease in leaf photosynthetic function. The comprehensive use of organic fertilizer, three major element fertilizer, and trace element fertilizer in autumn is the fundamental fertilizer. Fertilizer has its uniqueness and irreplaceability. Only through comprehensive fertilization can guarantee high and stable yields year after year. No single fertilizer can achieve high quality, high yield, and stable yield.
