NPK compound fertilizer contains two or more kinds of macroelements, which can provide rich nutrition for the growth and development of soil and plants. What should be paid attention to when applying NPK compound fertilizer?

There are different concentrations of compound fertilizer, we should pay attention to choose the appropriate concentration. At present, most compound fertilizers are distributed according to the average nutrient status of soil types and the proportion of fertilizer required by crops in a certain area. There are high, medium and low concentration compound fertilizers on the market.

Generally, the low concentration of total nutrients is between 25% ~ 30%, the medium concentration is between 30% ~ 40%, and the high concentration is more than 40%. And crops. Generally speaking, high concentration compound fertilizer is used for economic crops with good quality, less residue and high utilization rate. The concentration of compound fertilizer is high. Avoid direct contact between seeds and fertilizer. The nutrient content of compound fertilizer is high. If the seeds or seedling roots are directly contacted, the emergence of seedlings will be affected, and even the roots will be burnt. When sowing, seeds should be mixed with acupoints, and compound fertilizer should be applied in strips with an interval of 5-10 cm.

Matters needing attention in application of NPK compound fertilizer

It is necessary to pay attention to the nutrient composition of compound fertilizer with different proportion of raw materials. Different brands and concentrations of compound fertilizer use different raw materials, which should be selected and used according to the types of soil and crops. The compound fertilizer containing nitrate is not suitable for leaf vegetables and paddy fields. It is not suitable to use compound fertilizer containing ammonium ion, potassium chloride or chloride ion in saline alkali soil, potassium sulfate in crops or saline alkali soil, and potassium sulfate in paddy field and acid soil, otherwise it will reduce fertility and even poison crops.

The compound fertilizer containing two or more kinds of large elements is easy to volatilize or lose with the rain, and the phosphorus and potassium are fixed by the soil, especially the mobility of phosphorus in the soil is small, and it is not easy to be absorbed. The crop root system is on the surface, which is not conducive to deep root system. The drought condition in the fertilizer can not be dissolved, and it is worse in the development, so the compound fertilizer should go deep into the soil.

Pay attention to the time of fertilization

Organic fertilizer is slow to use, so it should be applied as early as possible. It is usually used as the base fertilizer before sowing or sowing, and fermentation will be better before use. The latter is less effective than the basic fertilizer.

Fertilizer has a quick effect, and should be used as base fertilizer one week in advance. Fertilizer should be applied before the critical period of crops or during the peak period of nutrient absorption to meet their needs.

How to make organic fertilizer, here are complete systems for your reference, https://organicfertilizermachines.com/organic-fertilizer-production-line/

Biological fertilizer plays an important role in inhibiting bacteria in soil. Therefore, under the premise of bacteria having reproductive growth time, it should be applied early, which can be applied with organic fertilizer for soil or during implantation or implantation before application.

NPK Drum Granulation Line

Second, pay attention to the application method

The main function of organic fertilizer is to improve the soil and provide nutrients, which is usually used as the basic fertilizer in the soil. Therefore, the organic fertilizer and soil should be mixed evenly with the deep plough to achieve the purpose of improving the soil. It can also be used in combination with microbial agents for acid-base reproduction, which will improve the soil environment, balance nutrition and increase the structure of soil aggregates. To make fertilizer met the requirements, it is necessary to select a realiable organic fertilizer machine manufacturer.

In the basic fertilizer, because the nutrients in the organic fertilizer are mainly nitrogen, it can reduce the nitrogen fertilizer in the organic fertilizer, the base fertilizer can use 30%, the rear fertilizer can use 70%. Phosphate fertilizer and potassium fertilizer can be paid off as base fertilizer at one time. The fluidity of phosphate fertilizer is poor, and the recovery effect is poor in the later stage. Therefore, the phosphate fertilizer should be applied to the soil as the base fertilizer.

To make compound fertilizer, here are machines for your reference:https://organicfertilizermachines.com/compound-fertilizer-production-line/

The best way to apply the fertilizer is to use the full solution quick acting fertilizer, such as the source Bank of P and K, which can be absorbed quickly after the decomposition of vegetables, which has little influence on the soil. Biomass fertilizer can be concentrated in planting sites or based on organic fertilizer because of its small quantity. The latter can be used to produce long bacteria by using the same kind of biological fertilizer to improve the removal ability and disease prevention effect of phosphorus and potassium solution.

Finally, pay attention to the dose

Different crops have different growth stages. The amount of fertilizer is different, so the amount of fertilizer should be controlled, and the fertilizer should be applied according to the different needs of plants, and the content of nutrient elements in soil should be considered comprehensively

The reason of wear of the shell of double roller granulator
Zhengzhou SX professional technicians will analyze the reasons for the wear of the roller shell on the compound fertilizer production line on the roller granulator

1. raw material moisture, pH

The roller sleeve is made of stainless steel. It reacts strongly with the pH value of the substance. Improper moisture and pH of the material will cause acid-base corrosion on the roller surface and damage the roller surface.

2. material factors

Roller extruder mainly deals with dry powder materials. Due to the different hardness of the material, uneven forces will be produced during extrusion and ball formation, which will increase the wear of roller skin. From the perspective of material factors, the other factor is the uniformity of the raw material particle size. Different sizes of raw materials also lead to uneven force and wear of roller sleeve.

3. feed uniformity coefficient

The center of the axis of the parallel bar of the extruder is parallel to the surface of the roll skin. If the feed is seriously uneven, one end feeds more and the other end is fed less, it will cause uneven force at both ends of the roller, increase the friction between the roller and the material, and cause the roller to wear.

Measures to reduce the wear of the roller shell in the compound fertilizer production line of the roller extruder:
In the process of pelletizing of the roller extrusion granulator, the roller skin is inevitably worn.

However, if used properly, it can effectively reduce the wear of the roller skin, thus extending the service life of the roller skin. According to the above factors, the following aspects can reduce the wear of the granulator.

1. for materials with high moisture content and high pH value, inspection and adjustment shall be carried out.

2. roller material, it is very necessary to select the cylinder cover with good material, wear resistance, torsion resistance and corrosion resistance.

3. in order to supply working materials, the uniformity of feed must be controlled to avoid wear caused by uneven axial force of roller.
Effective maintenance is an important means to reduce wear.

In conclusion, the damage factors should be avoided in the daily operation of the compound fertilizer production line from to the roller extruder. Therefore, manual and conventional use can reduce the wear of the pelletizing roller of extruder, prolong the service life and reduce unnecessary waste.

In the complete set of equipment required for biological fertilizer production, fermentation stacker has gradually become a convenient tool to replace labor and forklift to deliver materials, and is the mainstream product of composting development trend with important influence.

According to the characteristics of organic fertilizer dumper, the characteristics used in composting production are: when making fertilizer, the dumper needs to adjust the carbon nitrogen ratio, pH and water content of raw materials, and some auxiliary materials must be added. add to. Depending on the lathe, the main raw materials and various auxiliary materials which are roughly stacked together in proportion can be evenly mixed to achieve the ideal granulating effect suitable for the granulator.

In the traditional stacker operation, the raw material particles are fully contacted and mixed with the air, and a large amount of fresh air can be cultivated in the stacker, which helps the aerobic microorganisms to produce spontaneous combustion fermentation heat and increase the stacking temperature.

When the temperature is high, adding fresh air to the reactor can reduce the temperature of the chimney. It forms the shape of high temperature exchange, and all kinds of beneficial microorganisms develop and reproduce in the appropriate temperature range.

The stacker system can process the material into small lumps, make the dense material pile loose and elastic, and form the appropriate porosity to promote the entry of oxygen.
After proper moisture fermentation, the moisture content of organic fertilizer is less than 40%. In the fermentation process, the biochemical reaction will produce new water, and the consumption of raw materials by microorganisms will gradually release water as carrier.

Therefore, in the process of fertilizer production, the water content is reduced in time. In addition to the evaporation caused by heat conduction, the raw materials are shifted from the stacker to form a forced water vapor distribution.

Our new organic fertilizer manufacturing equipment includes transverse device, walking device and stacking steering device. The stacking turning device consists of two reducers fixed on the frame, which are connected to the corresponding reducers through couplings and fixed with spiral blades. The utility model has the characteristics of improving the fermentation rate, rapidly decomposing the compost, preventing the generation of peculiar smell, and shortening the fermentation time.

eIt is usually applied to: farm, fertilizer fermentation, fertilizer factory, brewery, food factory and sugar factory fermentation of raw materials in fermentation waste fermentation and sugar residue crushing.
