大邑县有黄壤耕地197,284亩,占耕地面积41.6％。1984年我局土肥站参加了省农科院土肥所的红黄壤小麦配方施肥区域(回归)试验。试验结果说明黄壤施用磷钾肥小麦有明显增产效果;在施氮磷基础上增钾则增产显著。1995年我们依据土壤普查各类土壤养分含量和肥料——作物产量反应模式,在全县大面积推广了配方施肥。我站在韩场乡六合村搞了小麦配方施肥百亩高产示范片,均实行撬窝点播,氮钾肥重底早追7∶3,磷肥全作底肥。试验结果,配方施肥明显地增加了小麦最高苗和有效穗,产量居全县高产示范片之首,单产689斤,比全县单产555斤增产24.1％,比六合村单产578斤增产19.2％。亩增纯收15.94
Dayi County has 197,284 mu of arable land of yellow soil, accounting for 41.6% of the arable land. Soil and Fertilizer Station in 1984 Bureau I participated in the Provincial Academy of Agricultural Sciences soil fertilizers red and yellow soil formula fertilization area (regression) test. The results showed that the application of P and K fertilizers significantly increased the yield of yellow soil; In 1995, we popularized the formula fertilization on a large scale in the whole county based on the soil nutrient content and the fertilizer-crop yield response mode of soil survey. I stood in the village of Han Liuhe village engage in wheat formula fertilization mu high-yielding demonstration films, are practicing paring nest on-demand, nitrogen and potassium heavy-end chase 7: 3, all phosphate fertilizer. The results showed that the formula fertilization significantly increased the maximum seedling and effective spike of wheat. The yield was the highest among all the high-yielding demonstration plots in the county with a yield of 689 kg, an increase of 24.1% over the yield of 555 kg in the county and a 19.2% increase over the yield of 578 kg in Liuhe Village. Mu increase net income of 15.94
