</p><p> 現(xiàn)代田園推薦：尿素不宜與碳銨混用。尿素施入土壤后，需先轉(zhuǎn)化成銨態(tài)氮或硝態(tài)氮后才能被作物吸收利用，但在堿性環(huán)境中轉(zhuǎn)化速度很慢，然而，碳銨屬于堿性肥料。土壤中碳銨和尿素混用后，會(huì)極大降低尿素的轉(zhuǎn)化速度，降低尿素肥效。3、不宜立即澆水。尿素是酰胺態(tài)氮肥且溶于水，必須要經(jīng)過2-10天的轉(zhuǎn)化過程。尿素追施后不宜立即澆水。如果施用后就澆水，大部分尿素將隨水流失。4、不宜增加使用量。一方面，尿素使用過量容易引起作物徒長(zhǎng)，不利于增產(chǎn)豐收；另一方面，尿素使用過量容易引起肥害，植株的幼嫩部分（幼葉、幼根）被灼傷，甚至可引起幼苗死亡。因此，應(yīng)結(jié)合作物的生長(zhǎng)需求，適量追施尿素。5、早春低溫時(shí)節(jié)不宜施用。尿素在轉(zhuǎn)化為能被作物吸收的銨根離子過程中，其轉(zhuǎn)化效果與土壤溫度密切相關(guān)。試驗(yàn)數(shù)據(jù)顯示，當(dāng)土壤溫度為30℃時(shí)，轉(zhuǎn)化過程較快，一般只需2-3天即可；而當(dāng)土壤溫度為10℃時(shí)，需7-10天甚至更長(zhǎng)時(shí)間。低溫季節(jié)施用尿素，肥效要比碳酸氫銨慢，因此，建議使用碳酸氫銨化肥。另外，尿素水溶液呈中性，容易被作物葉片吸收，可作為葉面肥噴施，但需控制噴施濃度，噴施濃度宜在1%-2%。專業(yè)生產(chǎn)各種肥料,產(chǎn)量高,性能穩(wěn)定。</p><div
