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(jìn)作物生長(zhǎng)發(fā)育為主要功能的肥料，具有肥效提高，促進(jìn)作物根系吸收養(yǎng)分，減少土壤養(yǎng)分流失等特點(diǎn)。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(jì)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(shí)品質(zhì)、增強(qiáng)作物抗逆性等特點(diǎn)。2、多肽尿素可用于糧食作物、經(jīng)濟(jì)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(jī)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(xué)性狀與碳酸氫銨相似，它同樣也會(huì)發(fā)生氨的揮發(fā)損失，所以要深施覆土。貴陽車用尿素價(jià)格莊稼一枝花,全靠肥當(dāng)家。</p><div

現(xiàn)代田園推薦：施肥時(shí)間，和人一日三餐一樣，作物也得按時(shí)補(bǔ)充營(yíng)養(yǎng)。很多農(nóng)戶現(xiàn)在是“不見兔子不撒鷹”，不見滿枝的病蟲不打藥，葉片不黃不施肥；要不就是行情好時(shí)三天一澆、五天一灌；還有的是追求“大而全”，所有肥料加在一起施用。凡事都得有個(gè)“度”，該施不施，不該施時(shí)亂施，這樣做如何能看到施肥效果？再如鈣肥，因吸收傳輸慢，應(yīng)該在需求高峰前及時(shí)補(bǔ)充施用，否則容易出現(xiàn)缺鈣癥狀。因此應(yīng)該在打好底肥的基礎(chǔ)上，依據(jù)作物的生長(zhǎng)需求及時(shí)、適當(dāng)?shù)淖贩什拍艹浞职l(fā)揮肥效。施肥時(shí)間還包含中適宜施肥的時(shí)間問題，早中晚氣溫、濕度有差異，建議避開中午高溫、高濕、強(qiáng)光時(shí)施肥，特別是葉面施肥時(shí)，這樣有利于避免傷害作物根系、嫩梢和葉片。 </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(guó)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(zhǎng)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。田園化肥,惠及咱農(nóng)民的好肥。</p><div

現(xiàn)代田園推薦：常規(guī)肥料葉面噴施濃度葉面施肥濃度直接關(guān)系到噴施的效果，如果溶液濃度過高，則噴灑后易灼傷作物葉片；溶液濃度過低，既增加了工作量，又達(dá)不到補(bǔ)充柑橘營(yíng)養(yǎng)的要求。所以在應(yīng)用中要因肥、因作物不同，因地制宜對(duì)癥配制。1、磷酸二氫鉀：常用濃度。方法：用300克磷酸二氫鉀加水100公斤，充分溶解后噴霧。2、高氮水溶肥：常用濃度1%~2%。使用時(shí)千萬注意，如果高氮水溶肥中縮二尿的含量如超過就對(duì)作物有毒害作用，所以這種高氮水溶肥就不能進(jìn)行葉面噴霧。3、糖醇鈣硼肥：常用濃度。4、螯合銅：常用濃度。5、螯合錳：常用濃度為。6、糖醇鋅、螯合鋅：常用濃度為。7、米醋：用200~250毫升對(duì)水45~50公斤噴施。8、鉬酸銨：按常用濃度為，噴施豆科作物。各類化肥尿素二銨-〔現(xiàn)代田園〕經(jīng)銷處,廠家直銷！貴州尿素批發(fā)</p><p

現(xiàn)代田園推薦：選擇合理的施肥方法：蔬菜中硝酸鹽含量與蔬菜種類、品種、不同部位有關(guān)，又與施肥技術(shù)和環(huán)境條件有關(guān)。在育種方面，把低硝酸鹽含量作為育種目標(biāo)之一是有意義的；在施肥技術(shù)與環(huán)境條件方面，蔬菜中硝酸鹽含量與土壤中氮的濃度和氮的種類等有密切關(guān)系，土壤中氮濃度越高，蔬菜中硝酸鹽含量越高，尤其在后期。所以，施用氮肥宜早，且不宜過多。使用**、復(fù)合、特種肥：由于農(nóng)產(chǎn)品對(duì)土質(zhì)、肥料要求不同，更需要**肥。例如，生產(chǎn)大蒜需要含硫較高的肥料，生產(chǎn)啤酒大麥需要減少氮肥的比例，生產(chǎn)500公斤小麥與600公斤小麥的配比不同。除了以上幾點(diǎn)外，也要知道肥料之間有“相克”矛盾。比如多施磷肥，多余的有效磷與土壤中的有效鋅結(jié)合形成難溶性的磷酸鋅沉淀，而引起土壤有效鋅的缺乏。不僅如此，多余的有效磷還會(huì)作物對(duì)氮的吸收，引起氮的缺乏。又比如多施鉀肥，多余的鉀會(huì)減少作物對(duì)氮、鎂、鈣、硼和鋅的吸收，引起農(nóng)作物體內(nèi)缺乏這些營(yíng)養(yǎng)元素。即使是有機(jī)肥也不可過多施用。如果施用過多，土壤中微生物與農(nóng)作物會(huì)出現(xiàn)“爭(zhēng)氮”“奪氮”的矛盾，引起土壤一段時(shí)間內(nèi)暫時(shí)缺氮，而且多余的有機(jī)質(zhì)與鋅形成絡(luò)合物或螯合物，會(huì)降低鋅的有效性。貴州農(nóng)業(yè)尿素報(bào)價(jià)</p><p
