Introduction of chemical fertilizer,organic fertilizer and biofertilizer
The type of fertilizer can be divided into different type and series.What differences of these fertilizer?What type fertilizer machine to be used in the fertilizer manufacturing process?The three main type fertilizer is the organic fertilizer,chemical fertilizer and biofertilizer.There we take these fertilizer as an example to compare with them.Share with you in this article.
The advantage of chemical fertilizer is that it has high nutrient content,very quick effect and yield increasing effect.There are many disadvantages of chemical fertilizer.For example,its nutrients are relatively simple.Generally,the use of chemical fertilizer should be combined with several fertilizers to release nutrients very quick,and the vertical balance supply of nutrients is relatively poor;it is easy to play,leach,and fix the way to lose,and the fertilizer utilization is not very high;if the fertilizer is not applied properly,it will not only be harmful to the growth of plants,but also may be harmful to the soil,so that the soil deterioation,reducing the fertility of the soil.
Organic fertilizer is a general term for organic rich fertilizer,which mainly includes farmyard manure,humic manure,all kinds of livestock and polutry manure,all kinds of green manure,compost,crop straw,firewood,defoliation,biogas fertilizer,and of course,commerical organic fertilizer.Plants (including fruit trees)can not directly absorb and utilize organic substaces such as plant straw,defoliating weeds,bark,etc.what fruit trees absorb abd utilize are humic acids,amino acids etc.formed by organic substances after maturity and decomposition.So strictly speaking,people's excrement and urine,all kinds of livestock excrement,branches,crop straw,firewood and leaves,which are not fermented and decomposed,can not only be called organic matter,not organic fertilizer.It is like raw rice,flour,oil and meat.It's just food,not food,not even directly edible.The organic fertilizer is widely to be used in the world,we are simplify to talk about the organic fertilizer manufacturing process.
In the fertilizer manufacturing process,it is equipped with different type and series organic fertilizer machine,it is the first step to ferment the raw materials using the fermenting technology to kill the bacterial in the raw materials.Then using the fertilizer mixer machine and fertilizer crusher machine to deal with the raw materials.Next to use the fertilizer granulator machine to make the organic fertilizer into granular shape.After that using the fertilizer screener machine to separate the quality fertilizer granulator from the inquailty fertilizer granulator.
Crop growth needs not only inorganic synthetic nutrition and mineral nutrition such as nitrogen,phosphorus and potassium,but also organic nutrition such as humic acid.Organic nutrition is the link of plant soil,soil microorganism and plant nutrition,which is in the center of plant nutrition.
The main functions of organic nutrition are:
(1)Directly involved in plant metabolism.Plants can directly absorb simple sugars,amino acids,humic acids and other organic compounds,which are directly involved in the biochemical processes of transformation,metabolism,synthesis and so on.
(2)Improve the effectives of mineral elements and fertilizer utilization.A large number of organic acids in humic acid make the insoluble mineral nutrients in the soil soluble,which is conducive to the affinity with lipophilicity and cell membrane,and improve the effectiveness of mineral nutrients.
(3)Improve crop resistance.Humic acid water-soluble polysaccharide can adjust the concentration of plant cytoplasm,reduce the freezing point and make plant cold resistant.Alkaloids and acids resist or kill pathogenic bacteria and harmful insects,and enhance the ability of plant disease and insect resistance.
(4)Active and increase soil benefical microorganisms.Humic acid provides sufficient nutrition for soil microroganism,and increases the population and quantity of soil microorganism.
(5)Improve the physical and chemical properties of soil.The active organic matter,humus and many kinds of nutrient elements that plants need.Organic fertilizer can improve the soil and heavy metals in the soil,improve the structure of the soil,improve the nutrient elements of the soil,enhance the ability of soil to maintain fertilizer and water,regulate the PH value of the soil,promote the activities of soilaggregate structure,and comprehensively improve the water,fertilizer,gas and heat status of soil.
It can be seen that its advantages is that is rich in organic matter,humus and many kinds of nutrient elements that plants need.Organic fertilizer can improve the soil and the heavy metals in the soil,improve the structure of the soil,improve the nutrient elements of the soil,enhance the ability of soil to maintain fertilizer and water,regulate the PH value of the soil,promote the activities of soil micororganisms,and improve the effectivesness of soil nutrients.
The disafvantage is that its nutrient concentration is low and the supply of soil nutrient elements is very slow,so the effect of increasing production is not so obvious.
3.Biological bacterial fertilizer
The application of biological bacterial fertilizer can increase the biomass of soil,active the soil and increase the utilization effect of soil nutrients.Biological bacterial fertilizer can play a catalytic role in the metabolism cycle of plant micrororganisms,promote the formation of soil aggregate structure,improve the intrnal space of soil,increase the biological activity of soil,enhance the release of avaliable nutrients,promote the growth of root system and improve the strees resistance of plants.Biological bacterial fertilizer and organic fertilizer have the best effect.Organic fertilizer provides organic matter,biological fertilizer provides benefical microorganisms.In addition,organic matter is the food of microorganisms.The more organic matter in the soil,the more micororganism can live better.
In the production process,the fertilizer granulator machine can choose different type,like the rotary drum granulator machine to be designed for producing the organic fertilizer,it also can be equipped in the npk,compound fertilizer production process.
