在分析我国南方水田地区气候、农艺条件和目前施用化肥状况的基础上 ,研制了一种新型的水田化肥深施机械。该机械采用了将化肥与适量水混合后由螺杆泵将其强制排出的原理 ,克服了一般水田化肥深施机械常遇到的化肥架空、粘附及堵塞问题。试验表明 ,该种机械适应性强 ,工作可靠 ,使用该种机械进行水田化肥深施具有明显的节肥增效作用 Based on the analysis of the climatic and agronomic conditions and the current status of the application of fertilizers in paddy fields in southern China, a new type of paddy fertilizer application mechanism was developed. The machine uses a fertilizer and the amount of water mixed by the screw pump to force the discharge of the principle to overcome the general paddy fertilizer fertilizer facilities often encountered fertilizer overhead, adhesion and plugging problems. Experiments show that the kind of mechanical adaptability, reliable work, the use of such machinery for paddy field fertilizer has obvious fertilizer and synergies
