The correct method of applying organic fertilizer to fruit trees in autumn

2019/07/10
In recent years, the increasing income of organic fertilizers in the fruit industry has been increasingly concerned by the majority of fruit farmers, and the amount of input has been increasing. How to apply it correctly and scientifically? Can be summarized as follows:
First, don't miss the best fertilization period. From August to late October, the fruit tree is close to the stoppage, and in the case of good blade protection, the optically contracted organic nutrients will accumulate back. Fertilization in this period is beneficial to the differentiation of flower buds, the healing of roots and the growth of new roots when deep turning. At the same time, it can improve the ventilation conditions in the deep layers of the soil, accelerate the microbial reproduction and enhance the decomposition of organic matter, thus laying a solid foundation for the fruiting and fruit growth of fruit trees in the next year. If considering farm work is too busy, the fertilizer is expensive; the best time for fertilization will be missed.


Second, the applying of base fertilizer should be based on the canopy, expanding outwards year by year, deep turning at least 40 cm depth. Then mix the mixed organic fertilizer into layers, backfill the surface of the earth to the lower layer, and place the turf on it. Many fruit farmers use organic fertilizers as chemical fertilizers to bury them or to bury them in shallow ditch. This saves time and effort, but the effect is not good. Organic fertilizer does not infiltrate into the soil like fertilizer, and it can’t solve the deep improvement of the soil at all, and it is easy to cause the roots to float and reduce the drought and cold resistance of the roots. In this way, the desire to stabilize the results is difficult to achieve.

Third, correctly understand and use of organic fertilizer. Organic fertilizer is a fertilizer that is decomposed by various animal or plant residues or residual materials, and decomposed into organic matter and mineral soluble nutrients by fermentation of beneficial bacteria. To put it simply, it is to re-convert waste and useless organic matter into nutrients for plant growth. There are many advantages, such as long fertilizer efficiency, water retention and fertilizer retention, loose soil, and balanced supply. While fertilizers are currently promoting benefits and yields, it is necessary to apply them at the right time. However, the various acid ions contained in the soil often cause the soil to harden and cause environmental pollution.

The content of nitrogen, phosphorus and potassium in some organic-inorganic compound fertilizers in commercial fertilizers is higher than that in pure organic fertilizers. Because of the organic matter, humic acid and biological fungus, the absorption rate in crop growth is better than that of purified fertilizer. However, when applied as a base fertilizer, it should be determined by the amount of soil organic matter. If the soil has high organic matter content and the floor is good, the fertilizer can also be used as a base fertilizer; if the soil has low organic matter content, it is not as good as a high-protein pure organic fertilizer.

Some experts divide organic fertilizer into three types: original ecological type, commercial type, and biologically active type. The original ecological organic fertilizer can be taken locally: human excrement, livestock (bovine, horse, pig, sheep, etc.) fertilizer or poultry moon, soil fertilizer, plant straw heap fertilizer, etc., can be applied as organic fertilizer, but the key is to be fully fermented. If it is not fully and deeply fermented, it will be no beneficial. In our orchards, unfertilized animal manure (including human excrement) is often spilled under fruit trees or digging into shallow pits. As a result, the end-of-the-line fruit trees die in a few years.

In the absence of fermented and fermented native organic fertilizers, it is recommended to use high-quality organic fertilizers. The quality and effect have been verified for many years and are reassuring.High-quality organic fertilizer can improve soil, improve soil fertility, enhance stress resistance, and significantly improve the quality and yield of fruit.
