桃園地區溶磷菌肥料效果田間驗證與整合性施肥方法之建立

Abstract

近年來行政院農業委員會農糧署大力推動友善環境農業，提出許多補助措 施，其中包含國產微生物肥料補助，希能引導農民使用微生物肥料，藉以改善農 田地力，替代部分化學肥料，並帶動微生物肥料產業發展。補貼標的以農糧署網站公告登載推薦國產微生物肥料品牌名單為限，目前可以選擇之微生物肥料商品達24 個，其中溶磷菌肥料商品佔22 個。為了解溶磷菌肥料於田間施用之功效，本場於2017 年及2018 年分別進行溶磷菌肥料產品肥 (功) 效田間驗證試驗，栽種需磷肥較高如青割玉米、嫩莖萵苣及紅莧菜進行田間試驗。結果顯示，溶磷菌肥料效果與土壤有效性磷具有相關性，若土壤有效磷缺乏，則所施用之溶磷菌肥料效果有限，另雖然施用溶磷菌肥料未見明顯增產效果，但若在肥力較高之土壤環境，減少化學肥料用量並配合使用溶磷菌微生物肥料，仍可達到一定的產量水準。 Quantitative indicators of activity of microbial fertilizer and evaluation methods of fertilizer (work efficiency) will be established to provide a reference for the future revision of the commodity specification of microbial fertilizer by the Agricultural Development and Reform Commission to ensure the quality of microbial fertilizer products and protect the rights of farmers. 2017 of microbial fertilizer products field evaluation methods established, the test crop is feed corn, according to the amount of fertilizer in the soil to adjust the amount of farmland soil and fertilizer on the two kinds of phosphate-solubilizing bacteria regularly to observe the impact on the yield. The results showed that the effects of using phosphate solubilizing fertilizer on the yield of maize under different phosphorus contents were all different. 2018 Establishing a field evaluation method for the fertilizer effect of phosphate-dissolving bacteria fertilizer products in Tao-yuan area and experiments of integrating phosphorus-dissolving bacteria microbial fertilizer with chemical fertilizer or organic fertilizer integrated fertilization method, Asparagus lettuce and Red Amaranth was tested in the field. The results showed that the yield difference between the treatments was not significant, although the application of the phosphate solubilizing fertilizer did not significantly increase the yield, but the reduction of the amount of chemical fertilizer and the use of phosphorus-dissolving bacteria microbial fertilizer conditions, can still achieve a certain level of production.
