Four Types of Fertilizers

1. Organic fertilizer. Organic fertilizer is significant in improving the quality of fruit. After organic fertilizer is applied to the soil, the organic matter can effectively improve the physical and chemical conditions of the soil, ripen the soil, enhance the fertilizer supply capacity and buffering capacity of the soil, and create good soil conditions for the growth of fruit trees.

At the same time, organic fertilizer decomposition, provide energy and nutrients for soil microbial activities, promote microbial activities, accelerate the decomposition of organic matter, and produce active substances to promote the growth of the root system and improve the quality of fruit. Insufficient organic fertilizer orchards, can be used to improve the organic matter of the soil grass system, Japan has been commonly used in fruit production grass system, the effect is good. It should be noted that the grass system as far as possible not to raise chickens, ducks combined, otherwise it will not increase the role of soil organic matter.

Pruned branches, leaves, weeds and crop stalks can be crushed and rotted as organic fertilizer.

2. Large amount of elemental fertilizer. Nitrogen, phosphorus, potassium is the three elements necessary for fruit trees, the application of these three elements have been generally recognized and accepted by the majority of fruit farmers, and to improve fruit production has played an important role. It should be noted that a large number of elements not only refers to nitrogen, phosphorus and potassium, but also includes carbon, hydrogen and oxygen. Carbon, hydrogen, oxygen these 3 elements are also very important, they are obtained from the air and water. So the orchard can not be depressed, must be ventilated and light, and watering should be timely, pay attention to maintain the appropriate moisture of the soil.

3. Biofertilizer. Nowadays, there are many kinds of biological fertilizers, and the ones that work well for fruit trees are mainly beneficial bacteria that decompose phosphorus, potassium and accelerate decomposition, and can enhance the decomposition of organic matter and soil permeability.

4. Medium and trace element fertilizer. Medium elements refer to silicon, calcium, magnesium, sulfur, the role of fruit trees second only to the large number of elements, research in recent years has shown that medium elements have an important role in improving tree resistance and fruit quality, should be given great attention, should not just treat them as dispensable trace elements to treat. Especially silicon element, which has good effect on fruit trees, is getting more and more attention.

Trace elements are iron, boron, manganese, copper, zinc, molybdenum and chlorine, which are essential for fruit trees. Trace elements for fruit trees, although the need for a small amount, but the lack of one is indispensable. Often fruit trees have such and such problems, many cases are caused by the lack of certain essential elements. So the appropriate amount of the missing trace elements, to improve yield and quality is very important.

In this regard, we should pay attention to two tendencies, one is not to pay attention at all, only know the application of large amounts of chemical fertilizers; the second is the application of excessive problems, trace elements in excess, will occur antagonism, play the opposite effect. Also note that in the sea cumulative plain area, because the soil contains more chlorine salts, so there is no need to add extra chlorine, and many fruit trees are avoid chlorine.
