現(xiàn)代田園推薦：尿素是人工合成的有機(jī)物，但它廣存在于自然界中，如新鮮人糞中含尿素。尿素作為氮肥始于20世紀(jì)初，20世紀(jì)50年代以后，由于尿素含氮量高、用途廣和工業(yè)生產(chǎn)流程的不斷改進(jìn)，尿素生產(chǎn)在世界各國(guó)發(fā)展很快。我國(guó)于20世紀(jì)60年代開始建立中型尿素廠。1973年后，隨著年產(chǎn)30萬噸合成氨的大型尿素廠陸續(xù)興建，我國(guó)成為世界上重要的尿素生產(chǎn)國(guó)。尿素已成為我國(guó)氮肥生產(chǎn)中**重要的品種之一。尿素肥料的有效成分分子式為CO(NH?)?，化學(xué)上又稱之為脲。1、尿素化學(xué)特性尿素肥料的含氮率為45%～46%，普通尿素為白色結(jié)晶，呈針狀或棱柱狀晶體，吸濕性強(qiáng)，目前生產(chǎn)的尿素肥料多為顆粒狀，并加用防濕劑制成一種半透明顆粒。在氣溫為20℃以下時(shí)，吸濕性較弱。隨著氣溫升高，其吸濕性明顯增強(qiáng)。尿素20℃時(shí)臨界吸濕點(diǎn)為相對(duì)濕度的80%，但至30℃時(shí)，臨界吸濕點(diǎn)降至，因此，要避免在盛夏潮濕氣候下敞開存放，貴陽長(zhǎng)效水觸膜尿素廠家批發(fā)。此外，尿素與其他肥料混合時(shí)會(huì)明顯降低吸濕點(diǎn)。30℃時(shí)與硫銨混合，可降至相對(duì)濕度的，與氯化鉀混合可降至，與硝銨混合可降至，尿素肥料與其他肥料摻混時(shí)應(yīng)特別注意這一問題，貴陽長(zhǎng)效水觸膜尿素廠家批發(fā)。大粒尿素的生產(chǎn)與試用實(shí)踐表明，這種尿素能較好地防止吸濕和延長(zhǎng)肥效，貴陽長(zhǎng)效水觸膜尿素廠家批發(fā)。承載綠色夢(mèng)想,成就幸福生活。貴陽長(zhǎng)效水觸膜尿素廠家批發(fā)</p><div

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(chǎng)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。貴州車用尿素多少錢一噸莊稼一枝花，全靠肥當(dāng)家。就找現(xiàn)代田園商貿(mào)！</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(fù)合肥料。在土壤中不殘留任何有害物質(zhì)，長(zhǎng)期施用沒有不良影響。畜牧業(yè)可用作反芻動(dòng)物的飼料。但在造粒中溫度過高會(huì)產(chǎn)生少量縮二脲，又稱雙縮脲，對(duì)作物有作用。我國(guó)規(guī)定肥料用尿素縮二脲含量應(yīng)小于?？s二脲含量超過1%時(shí)，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(jī)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(huì)導(dǎo)致PH升高2-3個(gè)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(shí)，便會(huì)對(duì)作物幼根和幼芽起作用，因此尿素不宜用作種肥。 </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）。尿素批發(fā),廠家直銷,質(zhì)量保證！</p><div
