Among the 16 main elements needed for the growth of fruit trees, carbon, hydrogen and oxygen come from nature, and the other 13 elements need to be provided by the soil and artificially supplemented, so if you want to make good fertilizer, you should understand the proportion of various elements in the plant body. When fertilizing, it is necessary to achieve complete nutrient and balanced fertilization, and clarify the proportion between each element, so as to give the correct fertilization formula. On the contrary, it will affect the fertilization effect.
The salinity index of the soil after the application of chemical fertilizers
If the osmotic pressure of the soil solution is close to or greater than the osmotic pressure of the roots, so as to affect the water and fertilizer absorption of the roots, the crops will wilt quickly and even die. Therefore, the salt index is too low to meet the growth of fruit trees; If the salt index is too high, it will destroy the capillary roots of the fruit tree, which will directly lead to the weakening of the tree. Therefore, the amount of fertilizer per mu of fruit trees should be strictly calculated when fertilizing, and whether there is still residue in the fertilizer applied last time, if there is a residue, the residual fertilizer amount should be calculated in the amount of fertilizer.
Fertilization method
When fertilizing, direct contact between chemical fertilizer and capillary roots should be avoided as much as possible, and repeated fertilization in the same fertilization pit should be avoided by changing the fertilization method (circle pit application, radial pit application, point pit application). At present, the more scientific fertilization method is the integration of water and fertilizer, which solves the problem of total nutrient fertilization and water supply at the same time, and will not cause harm to the soil and root system.
Soil viability and water supply
The higher the organic matter content in soil minerals, the more pores in the soil aggregate structure, the stronger the air storage capacity, the stronger the microbial activity, the higher the water retention ability, and the stronger the adsorption capacity of fertilizer particles. In this way, the soil can provide nutrients to the fruit trees in a sustained, balanced and continuous manner. At the same time, there is the issue of water holding capacity. If the moisture content in the soil is too high, it will crowd out the air in the pores of the aggregate structure, resulting in a decrease in the air content in the soil, which will lead to the suffocation and death of fruit tree roots, and at the same time affect the vitality of soil microorganisms, resulting in a decrease in its ability to decompose minerals and affect the effective supply of nutrients.
The growth potential of fruit trees
The stronger the tree, the more vigorous the root system will be, and the stronger the ability to absorb nutrients. Conversely, the weaker the tree, the lower the root activity, the worse the stress resistance, and the lower the absorption capacity of chemical fertilizers.
Fertilizer mixing
Fertilizers are divided into organic fertilizers, microbial fertilizers, microbial fertilizers, macro-element fertilizers and compound fertilizers, trace element fertilizers, mineral fertilizers, and water-soluble fertilizers. To solve the problem of mixed fertilizer, one of the methods is to use the soil cover method twice when fertilizing, first apply microbial fertilizer and trace element fertilizer and mineral fertilizer to the bottom layer and mix well with the soil, then cover the soil, then apply organic fertilizer and chemical fertilizer, and finally cover a layer of soil. If it is to be mixed in order to reduce labor intensity, the amount of organic fertilizer should be increased and mixed with a mixer to be applied to the soil in time after stirring, and mixed well with more soil. It is best to control the soil salinity index below 1%.
