Flushing construction Shenyang compound fertilizer What are the precautions for:
First of all, the current Compound fertilizer Not all of them can be fully water soluble. Some of them will have residue after being dissolved. Therefore, it is recommended to dissolve them in water before flushing when using them. This can improve the utilization rate of fertilizer without blocking the drip irrigation belt!
Secondly, when flushing compound fertilizers, it is recommended that growers do not flush multiple fertilizers at the same time. The fertilizers may show weak acid or alkalescence in aqueous solution, and flushing multiple fertilizers at the same time may cause reaction and reduce fertilizer efficiency!
Third, it is really not recommended for growers to adopt the method of flood irrigation when flushing compound fertilizers, because flood irrigation will greatly reduce the utilization rate of fertilizers. The compound fertilizer is dissolved in water and irrigated in flood. With the movement and infiltration of water flow, some nutrients will disappear with the water flow, and the utilization rate of fertilizer will decline. The effect will be better if drip irrigation is used!
Fourth, choose the right time to apply. The method of applying compound fertilizer by flushing with water has a quick effect, but the fertilizer effect is relatively short, which is an obvious disadvantage. Therefore, we should pay attention to the time when we use it. Generally, it is used in the critical period of crop growth, such as flowering period, fruit setting period (cowpea fruit setting period, peanut fruit expanding period, etc.). At this time, it can quickly supplement nutrition and promote a physiological process!
Compound fertilizer application with irrigation has become more and more common in the past two years, even in the field area has begun to appear. But we must pay attention to science when using it. Remember to select the appropriate compound fertilizer and apply it at the appropriate time to achieve good results!
