果園施肥撒布機之開發

臺東縣栽培的果樹主要包括番荔枝、鳳梨釋迦、柑桔及高接梨等，其中以番荔枝栽培面積達5,319公頃最多，收益較佳，最近幾年在番荔枝新品種(大目種、都蘭種)的生產上，果實重量在1台斤以上之特級品售價高，果農大量栽培及嫁接生產，並控制調節產期，每年7月至翌年4月為採收期，配合果實優質生產，須適時施肥，供應果樹養分，經調查果農施肥次數一般除每年2-3月利用小型挖土機挖溝全層立體施有機肥一次外，配合果樹生長及果實生育之養分需求再追肥，果農依據葉片診斷，土壤養分需求，以複合肥料或三要素混合肥料施肥達8-9次，果園施肥作業是重勞動，費體力的工作，尤其對水源較缺乏之地區更需把握時間，儘速在雨後快速施肥，由於農村勞力的逐漸老齡化、婦女化及勞力不足，勞動者從事重勞力的果園作業意願不高，致使雇工困難，果農希望施肥作業能輕體力化、省工作業。

Taidong County cultivates the fruit tree mainly includes the annona squamosa, pineapple Shakya, the sweet orange and Gao Chiehli and so on, amounts to 5,,319 hectares by the annona squamosa cultivation area many, income better, recently several years in the annona squamosa new variety (big item kind, Dulan planted) in the production, the fruit weight in 1 catty above top grade selling price was high, the fruit farmer massively cultivated and grafts the production, and the control adjustment childbirth time, every year from July to the next year April was the recovery time, the coordinate fruit high quality production, had at the right moment to apply fertilizer, supply fruit tree nutrient, After investigates the fruit farmer to apply fertilizer the number of times generally to use the small excavating earth machine trenching entire level besides the every year 2-3 month three-dimensional to execute organic fat, The coordinate fruit tree growth and the fruit birth nutrient of demand topdressing, the fruit farmer rests on the leaf blade diagnosis again, the soil nutrient demand, applies fertilizer by the compound fertilizer or three essential factors mixed fertilizer reaches 8-9 time, the orchard applies fertilizer the work is overtask, spends the physical strength the work, especially comparatively lacks the area to the water source to have to grasp the time, as fast as possible fast applies fertilizer after the rain, because countryside labor force gradually old age, woman and labor force insufficient, the worker is engaged in the heavy labor force the orchard work wish not to be high, causes the employee to be difficult, the fruit farmer hoped applies fertilizer the work to be able the light physical strength, the labor saving work.
