| Our product development speed very quickly in recent years, organic fertilizer. Market acceptance of higher and higher. In addition to commercial organic fertilizer for basic fertilizer, the fertilizer is also effective as seed sowing method of administration. In order to adjust the ratio of nutrients and increase the number of nutrients. When as seed and fertilizer mixed fertilizer is necessary. But many commodities in short fertilizer particle surface will produce a lot of water chemical reaction when mixed with organic manure fertilizer. Bonding occurs between the particles to each other so that the fertilizer can’t be achieved, mechanical application. In this paper, commercial organic fertilizer water content and pH, temperature, relative humidity, the type of fertilizer, mixing and fertilizer and effect of different factors of commercial organic fertilizer particle surface coating of inert material on the bond Manure and Fertilizer mix of commodities when. Test photographed at different times by each processing bonding processes and phenomena. Main results:1. Moisture content of 15.5%,13.2%,12.2% and 8.6%(water content of 8% or less does not produce binding) of commercial organic fertilizer mixed with urea. The higher the moisture content of the more obvious bond Commercial organic fertilizer 10% moisture content is critical moisture binding occurs, the basic bond does not occur if the water content is less than 10% organic manure and fertilizer mix merchandise.2. Commercial organic fertilizer urea bond, potato specialty fertilizer, MAP and DAP appeared mixed with varying degrees of MAP obvious bond, salt bond phosphodiesterase most serious, so the bond will be mixing occurs fertilizer types of influence.3. Air relative humidity of 80%, the organic fertilizer and urea mixed after commodity in 3min deliquescence phenomenon arises when the air relative humidity of 60% and 40%, the deliquescence phenomenon appears only in 30min. So with the relative humidity is increased bonding more likely.4. After the commodity organic fertilizer mixed with urea. Ambient temperature at 25℃ 3min appear deliquescence. When the ambient temperature of 5℃℃ 30min to appear deliquescence. Therefore, as temperatures rise fertilizers bonding process will be faster.5. Commercial organic fertilizer at a pH near 7.3 when mixed with urea bonding phenomenon relatively mild pH of 8.3 and 4.2. Bonding phenomenon is most serious pH4.2. So neutral commercial organic fertilizer can reduce the occurrence of adhesion.6. Commercial organic fertilizer and urea mixing ratio of 1:4 and 1:0.2 with respect to 1:0.6 and 1:0.8 bonding occurs less. Therefore fertilizer mixing ratio on the bond influential. Low fertilizer or low proportion of organic fertilizer can reduce the degree of adhesion occurred.7. Inert materials GAT, commercial organic fertilizer anti-adhesion effect HBT better surface after spraying. The maximum amount of talcum powder was 2.4kg/t and 5.8kg/t. GAT relatively inexpensive.These results indicate that:If it happens to take some measures can reduce or avoid the mixing of organic and chemical fertilizers when bonded goods. Recommendation manufacturers by reducing the water content, pH control the size and use of inert material handling manure to reduce the particle surface bonding; Are recommended to be administered at the time of mixing dry air and low temperature, and by choosing the type of compost and adjusting the mixing ratio to lower bond. |
