提高尿素利用率的方法1、深施尿素?zé)o論底肥還是用作追肥，尿素在轉(zhuǎn)化前是分子態(tài)的，不能被土壤吸附，應(yīng)防止隨水流失，都應(yīng)該深施覆土，施肥深度宜在10-12厘米為宜，這樣做能明顯提高肥料利用率。據(jù)研究尿素淺施2-3厘米，利用率*為30%；施肥深度為5厘米，利用率為45%左右；如果深施10-20厘米。那么利用率可達(dá)65%。2、早施尿素屬于酰銨態(tài)氮肥，在施入土壤后不能直接被土壤直接吸收利用，需要在土壤中脲酶作用下水解成碳酸銨或碳酸氫銨后，才能被作物根系吸收，因此，要在作物的需肥期前4～8天施用。如果施肥過晚，不*不利于肥效發(fā)揮，而且還有可能引起貪青晚熟。3、噴施分子體積小，極易被葉片吸收，所以尿素也是適合葉面噴肥的化肥，葉面噴肥吸收速度快，不受土壤環(huán)境影響，利用率高，而且施肥量少，但是增產(chǎn)效果明顯。尤其是在生長后期，根系的吸收力減弱，但是植株作物對養(yǎng)分需求量大，這時(shí)極易引起植株早衰，這時(shí)葉面噴肥能極好的解決。噴施過程中千萬要注意濃度，謹(jǐn)防濃度過高灼傷葉苗。4、混用尿素和有機(jī)肥、磷鉀肥以及微量元素混合施用，既能保持土壤養(yǎng)分平衡，又能提高肥料利用率，增產(chǎn)效果明顯。貴州農(nóng)業(yè)用尿素報(bào)價(jià)專業(yè)生產(chǎn)各種肥料,產(chǎn)量高,性能穩(wěn)定。</p><div

現(xiàn)代田園推薦：高鉀水溶肥什么時(shí)候用？首先，各個(gè)水溶肥廠家均推出了高鉀型的水溶肥，從肥料配方的角度，大部分的廠家以磷酸二氫鉀、磷酸一銨等磷酸鹽作為磷的來源，也有廠家采用聚磷酸銨等更穩(wěn)定聚合態(tài)磷酸鹽作為載體。高鉀水溶肥中含有磷，磷作為大量元素，不*是植物體組織的組成成分，還參與植物體內(nèi)包括能量轉(zhuǎn)換、酶的形成等諸多代謝過程，對作物的重要程度不言而喻；但是普通水溶肥的水溶性很差，難以擴(kuò)散并被植物利用?，F(xiàn)代田園商貿(mào)有限公司以誠信，互惠的原則，經(jīng)營和生產(chǎn)不同類型的化肥，如果您有需要，我相信我們一定會有個(gè)愉快的合作！好尿素肥滿地,豐碩果實(shí)滿谷倉。</p><div

現(xiàn)代田園推薦：尿素是在普通尿素生產(chǎn)過程中添加一定比例的尿酶劑制成的。其主要特點(diǎn)是減緩尿素分解速度，延長尿素的肥效期，減少氮素?fù)p失，提高氮肥利用率。有比普通尿素增產(chǎn)、節(jié)肥、省工的優(yōu)點(diǎn)。長效尿素為淺褐色或棕色顆粒，含氮46%。肥效期長，可達(dá)100?130天，做基肥或種肥一次施入，不必追肥。長效尿素施于土壤后，由于春季土壤溫度較低，土壤脲酶活性較弱，并有劑的作用，使長效尿素分解速度緩慢、生成的氨量較少，而作物幼苗需肥量也少；隨著氣溫升高，土壤溫度也增高，土壤中脲酶活性也隨之增強(qiáng)，劑的作用也逐漸減弱，長效尿素分解速度加快，生成的氨量增加，與此同時(shí)，作物生長也進(jìn)入旺季，需肥量大。因此，長效尿素的供氮過程與作物需肥規(guī)律基本趨于同步，使作物生長前期不過肥，中期不瘋長，后期不脫肥，為作物增產(chǎn)創(chuàng)造了良好條件。施用長效尿素比同量的普通尿素增產(chǎn)5%?8%，氮肥利用率提高6%?16%。用好肥，出好產(chǎn)，服務(wù)人民貢獻(xiàn)力量！貴州尿素</p><p

現(xiàn)代田園推薦：過往，農(nóng)戶常常憑借經(jīng)驗(yàn)施肥或者把每畝肥料的投入量，一般控制在自己能接受的成本極限以內(nèi)。從減少肥料投入，提高肥料利用率來說，科學(xué)計(jì)算施肥量，才可以讓農(nóng)戶朋友真正節(jié)約種植成本。施肥量的確定可以分為養(yǎng)分平衡法、田間試驗(yàn)法，這里先介紹養(yǎng)分平衡法的基本計(jì)算原理。養(yǎng)分平衡法的基本概念是：作物的養(yǎng)分吸收量等于土壤與肥料二者養(yǎng)分供應(yīng)量之和。肥料為作物提供的部分養(yǎng)分要通過施肥來進(jìn)行。但作物施肥量與肥料養(yǎng)分供應(yīng)量并不完全相同。因?yàn)橥度宿r(nóng)田的養(yǎng)分*有一部分被當(dāng)季作物吸收利用，考慮到肥料利用率因素，施肥量可通過下式推算：計(jì)劃作物施肥量(kg)＝(計(jì)劃產(chǎn)量所需養(yǎng)分總量－土壤養(yǎng)分供應(yīng)量)÷（肥料養(yǎng)分含量×肥料利用率(%)作物施肥量是指施用某一養(yǎng)分元素的量。具體到化肥品種，實(shí)物化肥用量則要通過下式推算：計(jì)劃作物施肥量(kg)＝實(shí)物化肥用量(kg)×有效成分含量(%)，其中：1.計(jì)劃產(chǎn)量所需養(yǎng)分總量kg)＝（計(jì)劃產(chǎn)量/100）×每形成100kg產(chǎn)量所需養(yǎng)分?jǐn)?shù)量（參照不同作物形成100kg經(jīng)濟(jì)產(chǎn)量所需養(yǎng)分大致數(shù)量表）。貴州農(nóng)業(yè)用尿素報(bào)價(jià)</p><p
