摘要

在谷物玉米生产中,施肥是一个重要的阶段,为了减少浪费和确保作物生长,必须合理施肥。对一种名为Gasprado的施肥工具进行了校准和评估,以评估其在槟榔屿的MARDI Seberang Perai的谷物玉米作物上施用尿素的性能。对装置滴尿素开度进行校准,设置合适的计量,满足130kg/ha的施用量。这是通过测量特定设置和距离下尿素的投放量来完成的。本机有四个计量装置,分别标示为MD1、MD2、MD3、MD4。此外,施肥器还配有春季栽培装置。对56行62米长的谷物玉米进行了施肥试验。记录拖拉机沿着62米的距离每跑完四行并在岬角转弯所花费的时间,以评估性能。该装置的计量装置MD1、MD2、MD3和MD4分别按B-1.5、B-0、B-0和B-0的设定刻度进行校准,得出的尿素施用量为133公斤/公顷,这是最接近建议用量的。作业平均工作速度为4.08 km/h,理论场容为1.224 ha/h。同时,该机器的有效田间容量为0.5208 ha/h,对于特定的农场设计,田间效率为42.5%。机械的使用可以加快玉米作物的施肥操作,但其性能取决于农场布局。

Calibration and Performance Evaluation of Grain Corn Fertilizing Implement
Fertilisation in grain corn production is an important stage that must be done properly in terms of the amount of fertiliser used to reduce wastage and ensure crop growth. A fertilising implement brand Gasprado, was calibrated and evaluated for its performance to apply urea to grain corn crops at MARDI Seberang Perai, Pulau Pinang. Calibration was conducted to set the right metering for the device's opening to drop  urea that  meets the application rate of 130kg/ha. This was done by measuring the amount of urea dropped for a particular setting and distance. The machine has four metering devices which were labelled as MD1, MD2, MD3 and MD4. Additionally, the fertiliser applicator also comes with spring tine cultivating devices. The implement was tested for fertilising 56 rows of grain corn in the distance of 62 m long. The times taken for the tractor to finish four rows per run along the 62-m distance and to turn at the headland were recorded to evaluate the performance. The implement's metering devices MD1, MD2, MD3 and MD4 were calibrated at setting scales of B-1.5, B-0, B-0 and B-0, respectively that gave the urea application rate of 133 kg/ha, which was the nearest rate to the recommendation. The average working speed of the operation was at 4.08 km/h with the theoretical field capacity to be at 1.224 ha/h. Meanwhile, the machine's effective field capacity was 0.5208 ha/h, which had a field efficiency of 42.5 % for the particular farm design. The use of machine can speed up the operation of applying fertiliser to the grain corn crop but the performance is dependent on the farm layout.
