To prevent "grossing" between fertilizers, the following methods can be used:
As far as possible to achieve balanced fertilization on the crop or partial application of fertilizer, not only cause waste, increase production costs, but also easily lead to the lack of other certain or certain nutrients. When fertilizing, it is necessary to calculate the amount of fertilizer according to the difference in the structure of the fertilizer needed for crops and the fertility of the soil.
According to the proportion of crop demand, the same fertilizer should be used for the same increase and decrease in fertilizer, supplemented by single fertilizer, such as for crops with high potassium content, such as vegetables with tubers and tuberous roots, the sulfur-based compound fertilizer can be used. Based on the appropriate addition of potassium sulfate as a supplement to the simple fertilizer.
If staggered application period or application site of zinc fertilizer and phosphate fertilizer if mixed, will inevitably produce "phase g". Therefore, phosphate fertilizer should be used as base fertilizer or basal fertilizer, and zinc fertilizer should be used as top dressing. Nitrogen, phosphorus, potassium and other macronutrient fertilizers should be dominated by rhizosphere topdressing, and microfertilizers should be foliar sprayed.
To narrow the contact range, nitrogen and potassium fertilizers can be used as a means of spreading; the phosphate fertilizer can be used as a method of concentrated fertilization; the micro-fertilizer can be seed dressing, soaking, and rooting, so that the trace elements are confined to the smaller range of the root. Not in contact with a large number of elements.
Centrifuges are not only found in labs, but also in surgeries and hospitals. Through centrifugation, blood can be broken down into its different components, depending on with which substance the centrifuge tubes is displaced. In this category, Yingmed offers you a range of various products from Benchtop centrifuges up to Mini centrifuges and centrifuge Tubes.
Other lab liquid handling devices like Blood roller mixer, Vortex, Oscillator, orbital Shaker and Hemoglobinometer will found in this category.
