現(xiàn)代田園推薦：近年來，農(nóng)民朋友使用復(fù)合肥越發(fā)頻繁，而復(fù)合肥市場也是種類頻出，讓人應(yīng)接不暇。關(guān)于硝硫基、硫基、氯基、尿基復(fù)合肥到底有啥區(qū)別，你真的懂嗎？下面小編就帶大家了解一下。硝硫基復(fù)合肥是指氮元素由硝酸銨提供，鉀素的來源采用硫酸鉀，或?qū)⒙然浢撊ヂ入x子制成的復(fù)合肥料。不含縮二脲，氯離子低于3%。硫基復(fù)合肥是指鉀素的來源采用硫酸鉀，或?qū)⒙然浢撊ヂ入x子制成的復(fù)合肥料，且氯離子的含量不能超過3%，否則就是氯基復(fù)合肥。氯基復(fù)合肥是指鉀元素以氯化鉀的形式存在，可分為單氯和雙氯產(chǎn)品，單氯是指除鉀元素是氯化鉀形式外，氮元素為尿素等不含氯離子的制成，雙氯是鉀元素以氯化鉀形式、氮元素以氯化氨的形式取得的復(fù)合肥。黔南州長效水觸膜尿素生產(chǎn)廠家現(xiàn)代田園化肥,農(nóng)民豐收的好伴侶。</p><div

現(xiàn)代田園推薦：高鉀水溶肥的優(yōu)點(diǎn)都在什么地方？1.高鉀水溶肥可以促進(jìn)酶的活化，鉀是植物體內(nèi)多種酶的活化劑。氧化還原酶、合成酶、轉(zhuǎn)移酶和磷酸激酶等均需要鉀的活化，它們參與植物體內(nèi)重要的生理代謝，包括糖分代謝、蛋白質(zhì)代謝、核酸代謝等。2，提高產(chǎn)量與果實(shí)品質(zhì)，鉀能提高細(xì)胞膜的運(yùn)輸能力和促進(jìn)同化產(chǎn)物的轉(zhuǎn)運(yùn)，并向著果實(shí)的方向進(jìn)行，葉面噴施鉀肥后，首先葉片中的含鉀量提高，隨后向果實(shí)中轉(zhuǎn)移，促進(jìn)果肉細(xì)胞生長，從而促進(jìn)果實(shí)膨大，增加果樹產(chǎn)量。第二十七段：高鉀水溶肥就是含有大量的鉀而成為的水溶肥料，高鉀水溶肥現(xiàn)在是我們公司眾多水溶肥種類中使用比較多的一種配方肥，對(duì)瓜果類膨大、上色、加快成熟等作用明顯，具體優(yōu)勢如下幾點(diǎn)：（1）高鉀水溶肥元素能提高植物抗倒伏、抗旱、抗病的能力。其實(shí)正規(guī)來講養(yǎng)分是無法提高作物抗病能力，可以理解成作物吃的好自然長的好，就像人身體吃好喝好營養(yǎng)跟的上健康才不會(huì)生病是一個(gè)道理。（2）加快成熟，可溶性的鉀元素如水溶肥中常用的、磷酸二氫鉀等這些鉀源對(duì)促進(jìn)作物果實(shí)膨大、快速上色成熟等有明顯促進(jìn)作用。

現(xiàn)代田園推薦：施用有機(jī)肥要科學(xué)合理,應(yīng)注意以下幾點(diǎn)，一、注意選擇的有機(jī)肥。的有機(jī)肥是作物高產(chǎn)的基礎(chǔ)，而現(xiàn)在農(nóng)民施用的有機(jī)肥，大都是買來的商品肥，質(zhì)量普遍較低，有些甚至摻雜了城市污泥、生活垃圾等，根本就達(dá)不到有機(jī)質(zhì)含量的標(biāo)準(zhǔn)。即使是一些買來的雞糞，也有不少摻雜了泥土，或被一些不法商販摻入了火堿（用于增加體積），這些劣質(zhì)有機(jī)肥施入土壤后，效果可想而知。因此，生產(chǎn)中一定要選用的有機(jī)肥，選用商品有機(jī)肥時(shí)比較好選用正規(guī)大廠家生產(chǎn)的。二、充分腐熟發(fā)酵后再施用。有機(jī)生物肥料，能活化土壤、改良土壤，增強(qiáng)農(nóng)作物的抗病、抗蟲、抗災(zāi)能力，能提高作物品質(zhì)和產(chǎn)量。但自然界中的禽畜欄、人畜糞肥及餅粕類等有機(jī)肥必須要充分腐熟發(fā)酵后再施用。經(jīng)過發(fā)酵后，一是均衡了有機(jī)肥中的酸性，減少了硝酸鹽含量，補(bǔ)充了水分，有利于自然界土壤中微生物菌的組合應(yīng)用；二是發(fā)酵后能殺滅原糞肥中寄生蟲卵、有害生物病菌等直接給作物和土壤帶來的病菌與危害。三、配合生物肥施用效果好。有機(jī)肥無論基施還是沖施，比較好配合生物肥使用。為什么要配合生物肥呢？因?yàn)橛袡C(jī)肥在與生物肥配合沖施后，生物肥中的生物菌能加速有機(jī)肥中有機(jī)物的分解，使其更有利于作物吸收。控釋肥，肥效長。品種全，多營養(yǎng)。用量少，效果強(qiáng)。黔西南車用顆粒尿素化肥價(jià)格</p><p style="text-indent:25px">尿素化肥看這里，土地肥沃收成好。銅仁長效水觸膜尿素廠有哪些</p><p> 尿素易溶于水，20℃時(shí)的溶解度為105g/100g水，比硫銨高出一倍。尿素為中性有機(jī)分子，在水解轉(zhuǎn)化前不帶電荷，不易被土粒吸附，故很易隨水移動(dòng)和流失。尿素一經(jīng)施入土壤，在脲酶催化作用下即開始水解。脲酶由多種土壤微生物所分泌，也廣存在于多種植物體內(nèi)。脲酶數(shù)量及其活性常與土壤有機(jī)質(zhì)含量高低有密切關(guān)系。表土中脲酶比心土和底土中多。尿素水解的反應(yīng)式為：CO(NH?)?+2H?O→(NH?)?CO?(NH?)?CO?→2NH?↑+H?O+CO?尿素水解速度與土壤酸度、溫度、濕度以及土壤類型、熟化程度及施肥方式等有關(guān)。濕度適宜時(shí)，氣溫越高水解速率越大。一般來說，當(dāng)氣溫為10℃左右時(shí)，全部水解需1～2周，20℃時(shí)4～5d，30℃時(shí)1～3d。作物根系可以直接吸收尿素分子，但數(shù)量不大。施入土壤的尿素主要以水解后形成的銨和硝化后的硝態(tài)氮形態(tài)被吸收。因而，尿素施入土壤后表現(xiàn)出的許多農(nóng)化性質(zhì)與碳銨相類似。尿素水解后由于生成了氨氣，氨揮發(fā)損失成為氮素?fù)p失的重要途徑。國內(nèi)外的研究結(jié)果表明，若將尿素撒施于水田表面，由于水解后產(chǎn)生氨，稻田水層的pH值明顯上升(有時(shí)可達(dá)到)，加上水層中藻類快速生長大量利用二氧化碳，使水中的氫氧根難以與二氧化碳結(jié)合，氨揮發(fā)可能會(huì)進(jìn)一步加劇。銅仁長效水觸膜尿素廠有哪些</p><p
