現(xiàn)代田園推薦：而要防止肥料之間“相克”，可采取以下方法：1.盡可能做到平衡施肥對農(nóng)作物偏施或多施單質(zhì)肥料，不*浪費了肥料，增加了生產(chǎn)成本，而且易導致其他某種或某些營養(yǎng)元素的缺乏。施肥時，要根據(jù)農(nóng)作物需肥結(jié)構(gòu)的不同和土壤的供肥能力，做到量出為入，不偏不少營養(yǎng)元素的平衡，這樣就可以相安無事。2.要增同增，要減同減根據(jù)不同作物對各種營養(yǎng)元素的需求比例關(guān)系，要增同增，要減同減。相對單質(zhì)肥料而言，復合肥或復混肥營養(yǎng)元素的比例關(guān)系比較適當和協(xié)調(diào)。因此，施肥時應以復合肥為主，以單質(zhì)肥料為輔，如對于以塊莖、塊根為收獲對象的蔬菜等需鉀量大的農(nóng)作物，可在施用硫基復合肥的基礎(chǔ)上，再適當增加硫酸鉀單質(zhì)肥料作補充。3.錯開施用時期或施用部位鋅肥和磷肥若混施，必然會產(chǎn)生“相克”，貴州車用尿素價格，貴州車用尿素價格。因此磷肥應作底肥或基肥施用，鋅肥應作追肥施用。氮、磷、鉀等大量元素肥料應以根際追肥為主，貴州車用尿素價格，微肥應采取葉面噴施的方法。4.縮小接觸范圍氮、鉀肥可采用撒施的方法；磷肥可采用集中施肥的方法；微肥可采用拌種、浸種、蘸根等方法，使微量元素局限在根部這一較小的范圍內(nèi)，盡量不與大量元素接觸。要想作物長得好，使用尿素少不了！貴州車用尿素價格</p><div

現(xiàn)代田園推薦：多肽尿素是一種新型化肥，它以多肽聚氨基酸為主要載體，是以刺激和促進作物生長發(fā)育為主要功能的肥料，具有肥效提高，促進作物根系吸收養(yǎng)分，減少土壤養(yǎng)分流失等特點。多肽尿素和普通尿素有什么區(qū)別?1、多肽尿素和普通尿素相比，肥料利用率提高5%以上，節(jié)肥20%左右。糧食作物增產(chǎn)，棉花等經(jīng)濟作物增產(chǎn)，每667平方米(1畝)節(jié)本增收76～。還具有改善果實品質(zhì)、增強作物抗逆性等特點。2、多肽尿素可用于糧食作物、經(jīng)濟作物、油料作物以及蔬菜、花卉、果樹等，均具有的增收效果。3、普通尿素是中性、分子態(tài)有機氮化物，作物根系能夠直接吸收的分子態(tài)尿素，但數(shù)量很少。尿素施入土壤后，只有在土壤中脲酶的作用下，被水解轉(zhuǎn)化成銨態(tài)氮以后，才能大量地被作物根系吸收。4、普通尿素需經(jīng)轉(zhuǎn)化才能被作物大量吸收。尿素在土壤中轉(zhuǎn)化的產(chǎn)物是碳酸銨和碳酸氫銨，因此，尿素施入土壤后的農(nóng)業(yè)化學性狀與碳酸氫銨相似，它同樣也會發(fā)生氨的揮發(fā)損失，所以要深施覆土。貴陽車用尿素作用用好肥，出好產(chǎn)，服務人民貢獻力量！</p><div

現(xiàn)代田園推薦：尿素是一種高濃度氮肥，屬中性肥料，也可用于生產(chǎn)多種復合肥料。在土壤中不殘留任何有害物質(zhì)，長期施用沒有不良影響。畜牧業(yè)可用作反芻動物的飼料。但在造粒中溫度過高會產(chǎn)生少量縮二脲，又稱雙縮脲，對作物有作用。我國規(guī)定肥料用尿素縮二脲含量應小于?？s二脲含量超過1%時，不能做種肥，苗肥和葉面肥，其他施用期的尿素含量也不宜過多或過于集中。尿素是有機態(tài)氮肥，經(jīng)過土壤中的脲酶作用，水解成碳酸銨或碳酸氫銨后，才能被作物吸收利用。因此，尿素要在作物的需肥期前4～8天施用。尿素適用于一切作物和所有土壤，可用作基肥和追肥，旱水田均能施用。由于尿素在土壤中轉(zhuǎn)化可積累大量的銨離子，會導致PH升高2-3個單位，再加上尿素本身含有一定數(shù)量的縮二脲，其濃度在500ppm時，便會對作物幼根和幼芽起作用，因此尿素不宜用作種肥。 </p><p> 提高尿素利用率的方法1、深施尿素無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，應防止隨水流失，都應該深施覆土，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，這時極易引起植株早衰，這時葉面噴肥能極好的解決。噴施過程中千萬要注意濃度，謹防濃度過高灼傷葉苗。4、混用尿素和有機肥、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。一分耕耘一分財,肥料就用現(xiàn)代田園尿素化肥。</p><div

現(xiàn)代田園推薦：農(nóng)業(yè)尿素可作基肥和追肥，有時也可作種肥。尿素在轉(zhuǎn)化前處于分子狀態(tài)，不能被土壤吸收，應防止隨水流失；轉(zhuǎn)化后形成的氨也容易揮發(fā)，應與土壤深施尿素。（一小部分土壤以分子形式溶解在土壤溶液中，通過氫鍵被土壤吸收。剩下的部分用脲酶水解成碳酸銨，然后生產(chǎn)碳酸氫和氫氧化銨。NH4+可以被植物和土壤膠體吸收，nco3-也可以被植物吸收。因此，尿素施入土壤后不會殘留有害成分。此外，尿素中的縮二脲在脲酶的作用下也能分解成氨和碳酸。尿素在土壤中的轉(zhuǎn)化受土壤pH、溫度和水分的影響。土壤中性時，土壤溫度越高，轉(zhuǎn)化越快；當土壤溫度為10℃時，尿素完全轉(zhuǎn)化為銨態(tài)氮需要7-10天，20℃需要4-5天，30℃需要2-3天。尿素水解后產(chǎn)生氨氮，表面施氮會引起氨揮發(fā)，特別是在堿性或堿性土壤中。因此，在施用尿素時，應深施土壤，并應施用于稻田的還原層。）尿素適用于所有作物和所有土壤。可作基肥和追肥，也可用于旱田。尿素能在土壤中積累大量的銨離子，使土壤pH值提高2-3個單位。此外，尿素本身也含有一定量的縮二脲。當尿素濃度為500ppm時，會作物的幼根和幼芽生長。因此，尿素不宜作為種子肥使用。尿素（氮肥）能促進細胞分裂和生長，使枝葉生長茂盛。綠色環(huán)保+肥效高,〔現(xiàn)代田園商貿(mào)〕,提高作物養(yǎng)分！貴陽尿素廠</p><p

style="text-indent:25px">現(xiàn)代田園推薦：尿素，又稱碳酰胺，是由碳、氮、氧、氫組成的有機化合物是一種白色晶體。簡單的有機化合物之一，是哺乳動物和某些魚類體內(nèi)蛋白質(zhì)代謝分解的主要含氮終產(chǎn)物。也是目前含氮量比較高的氮肥。作為一種中性肥料，尿素適用于各種土壤和植物。它易保存，使用方便，對土壤的破壞作用小，是目前使用量較大的一種化學氮肥。工業(yè)上用氨氣和二氧化碳在一定條件下合成尿素。尿素易溶于水，在20℃時100毫升水中可溶解105克，水溶液呈中性反應。尿素產(chǎn)品有兩種。結(jié)晶尿素呈白色針狀或棱柱狀晶形，吸濕性強，吸濕后結(jié)塊，吸濕速度比顆粒尿素快12倍。粒狀尿素為粒徑1～2毫米的半透明粒子，外觀光潔，吸濕性有明顯改善。20℃時臨界吸濕點為相對濕度80%，但30℃時，臨界吸濕點降至72.5%，故尿素要避免在盛夏潮濕氣候下敞開存放。在尿素生產(chǎn)中加入石蠟等疏水物質(zhì)，其吸濕性下降。貴州車用尿素價格</p><p
