What is Sprayer Calibration? Why does calibration matter? Well, calibration is alerting the operator of a sprayer to the amount of product being applied to the turfgrass during the application. The process of calibration is simple and needs to be conducted every 6 months. So how to calibrate?
什麼是噴藥車校正？為什麼校正很重要？校正能夠提醒噴藥車的操作手在施作時噴灑到草坪草上的產品用量是多少。校正的程序很簡單，需要每 6 個月進行一次。那麼如何進行校正呢？
Calibration is done slightly differently depending on what sprayer you are calibrating. A boomless nozzle is going to be done differently than a spray hawk – however the process is more or less the same. We need to measure the speed in which we are applying the chemicals. Whether its walking, driving, or flying – we need to know how fast we are going. The faster we go, less product is going to be applied if we are spraying at a constant rate. We need to know what pressure we are spraying at. We need to know the spray width, how many nozzles, and nozzle spacing. From here, we need to measure the output each nozzle for a set amount of time. We then plug that output into an equation, and it will give us our application rate. A relatively simple process.
校正的方式會根據噴藥車的種類而略有不同。無尾翼噴桿的噴嘴會與手推式噴桿的校正方式不同 – 但程序大致上還是差不多的。我們需要測量施作化學藥劑時的行進速率。無論是步行、開車還是飛行 – 我們都需要知道我們行進的速度有多快。如果行進的速率是不變的，那麼我們走得越快，施作的產品量就越少。我們需要知道噴灑的壓力是多少。我們需要知道噴灑寬度、噴嘴數量和噴嘴間距。然後，我們需要測量每一個噴嘴在一段預設時間內的輸出量是多少。接著我們將此輸出量代入一個公式，就會得到單位面積施作量。這是一個相對簡單的過程。
Why does this matter you must ask. A lot of other golf courses in Taiwan don’t calibrate their sprayer, why should I if they don’t. Well, simply put, you are running the risk of wasting money and destroying what you are attempting to groom every day. All calibration is, is an observation of what you are doing. 300LPH and 1000LPH are 2 very different application rates. These 2 different applications would have 2 very different purposes. You would not want to apply foliar products at 1000LPH, that’s simply too much water. Thus, if you don’t know if you are spraying at 300LPH or 1000LPH, how are you going to understand how much product you are using. You run the risk of wasting money by either applying way too much product, or way too little product. Any misapplication should be considered money wasted.
您會想問，為什麼這很重要？台灣很多高爾夫球場都沒有在校正他們的噴藥車，如果他們沒在做，那我為什麼要做？ 簡單地說，這樣的風險在於，會浪費金錢以及破壞您每天努力培養的成果。所有的校正都是對於您的作業進行的觀察。每公頃300公升 和 每公頃1000 公升 是兩種截然不同的單位面積施作量。這 2 種不同施作量的目的會是不同的。您不會想要以每公頃1000 公升的量來施作由葉面吸收的產品，那樣的水量實在是太多了。因此，如果不知道是以每公頃300公升還是每公頃1000 公升進行噴灑的話，那麼您將如何知道施作的產品用量是多少呢？如果施作過多或太少的產品用量，您將會有浪費金錢的風險。任何錯誤的施作都應視為浪費金錢。
Calibration is a simple process that is necessary when understanding what you are trying to achieve. Without calibration, you run the risk of killing all your grass. Without calibration, you run the risk of wasting a lot of money. Calibrate your sprayer the correct way, it doesn’t hurt anything.
