Difference of Compound fertilizer

硫基、氯基、尿基复合肥的区别及使用方法

fertilizer

Sulfur based compound fertilizer

 

Potassium is the source of potassium sulfate, or potassium chloride to remove chloride ions made of compound fertilizer, and the content of chloride ions can not exceed 3%, or it is chlorine based compound fertilizer.


硫基复合肥

是指钾素的From采用硫酸钾,或将氯化钾脱去氯离子制成的复合肥料,且氯离子的含量不能超过3%,否则就是氯基复合肥。

Chlorine based compound fertilizer

 

Refers to the potassium is present in the form of potassium chloride can be divided into single chlorine and chlorine products, the single chlorine is that potassium from potassium chloride, nitrogen element is made from urea without chlorine ions ,and double chlorine is potassium to potassium chloride, nitrogen in the form of ammonium chloride to obtain the compound fertilizer.


氯基复合肥 

是指钾元素以氯化钾的形式存在,可分为单氯和双氯产品,单氯是指除钾元素是氯化钾形式外,氮元素为尿素等不含氯离子的制成,双氯是钾元素以氯化钾形式、氮元素以氯化氨的形式取得的复合肥。

 

Urea based compound fertilizer 

 

Refers to obtain nitrogen from urea, urea based compound fertilizer are generally high nitrogen products, especially the nitrogen content is more than 20, ammonium chloride and ammonium bicarbonate production don’t such a high nitrogen content.

sulfur based compound fertilizer prices the most expensive in the same ratio of compound fertilizer, but chlorine radical and urea based compound is complicated, a single chlorine products is generally urea based compound fertilizer, double chloric compound fertilizer price slightly than urea based compound fertilizer with content slightly low.


尿基复合肥

是指复合肥中氮元素以尿素的形式获得,尿基复合肥一般都是高氮产品,特别是氮元素含量20以上的复合肥,氯化氨和碳铵生产不出这么高的氮含量。

这三种同样配比的复合肥硫基复合肥价格最贵,但氯基和尿基比较就复杂了,单氯产品一般都为尿基复合肥,双氯的复合肥价格稍比尿基复合肥同含量稍微低些。

 

1The different composition

Sulfur based compound fertilizer containing low chloride ions, the national standard is less than 3%, and contains a lot of sulfur element, can effectively improve the soil sulfur deficiency symptoms; chlorine based compound fertilizer contains large amounts of chlorine,  Have a bad effect on some crops.Urea based compound fertilizer nitrogen in urea (amide nitrogen) , urea in the soil Urease action of urea in soil by soil microorganism, When the water is suitable for the hydrolysis of ammonium carbonate

 or ammonium bicarbonate temperature is higher, the hydrolysis convey of ammonium carbonate speed faster and faster, fertilizer is fast, ammonium carbonate is not stable, so the application of urea based compound fertilizer, should be deeply that soil, prevent N losses.

一、成分不同

硫基复合肥中含氯离子低,国家标准规定小3%,且含有大量的硫元素,能有效的改善土壤缺硫症状;氯基复合肥含有大量氯元素,对一些作物有不良的影响;尿基复合肥料中氮为尿素(酰胺态氮)尿素在土壤中经土壤微生物分泌的脲酶作用水解成碳酸铵或碳酸氢铵当水分适当时,温度越高,水解越快转达化为碳酸铵速度越快,肥效也就越快,碳酸铵很不稳定,所以施用尿基复合肥时,应深施盖土,防止氮素损失。

2The different process

chlorine ion content is extremely low in Sulfur based compound fertilizer, remove the chlorine ion in the production process; chlorine based compound fertilizer is not removed the chlorine ions which will be bad for the chloride crop in the production process, so products containing large amounts of chlorine; urea based compound fertilizer make up the urea melting urine or molten urine produced by heating of solid urea with potassium sulfate to make slurry.

 二、工艺不同

硫基复合肥中氯离子含量极低,生产过程中脱去了氯离子;氯基复合肥在生产过程中没有去掉对氯作物有害的氯离子,因此产品中含有大量的氯元素;尿基复合肥在生产过程中把尿素制得的熔融尿液或将固体尿素加热制得的熔融尿液与氯化钾或硫酸钾配制成料浆

3The different adaptation scope

Sulfur based compound fertilizer applied in various types of soil and different crops, and can effectively improve the appearance and quality of all kinds of economic crops, can significantly improve the level of agricultural products; chlorine based compound fertilizer is adverse effects on the yield and quality of chlorine crop, which will reduce the economic benefits of this kind of economic crops; urea based compound fertilizer is easy to produce biuret in the production process, as a kind of seed manure, should quarantine seed manure.

三、适作范围不同

硫基复合肥适用各类土壤和各种作物,且能有效提高各类经济作物的外观、品质,可显着提高农产品等级;氯基复合肥对氯作物的产量和品质均有不良影响,严重降低该类经济作物的经济效益;尿基复合肥在生产过程中容易产生缩二脲,作种肥时,应与种肥隔离

4The Different fertilizer effect

The elemental sulfur is the fourth major nutrition elements after nitrogen, phosphorus and potassium of sulfur based compound fertilizer, can effectively improve the situation of lack of sulfur in the soil, supply the sulfur to soil directly; chlorine based compound fertilizer in the soil formed in a large number of chloride ion, easy cause soil compaction, salinization and alkalization and other undesirable phenomena. Thus, to worsen the soil environment, the nutrient absorption capacity of crops decreased,

However, chloride ions can promote photosynthesis and fiber formation and so on. And it is particularly suitable for bast fiber crops. After make the urea based compound fertilizer into the soil, can converted to ammonia nitrogen and nitrate nitrogen plant to absorb, therefore, in the process of application, the lower temperature regions should be applied in advance.

 

 四、肥效不同

硫基复合肥其硫元素是继氮、磷、钾后的第四大营养元素,可有效改善土壤中缺硫状况,为作物直接提供硫元素;氯基复合肥在土壤中形成大量的氯离子的残留,易造成土壤板结、盐化、碱化等不良现象,从而恶化土壤环境使作物的养分吸收能力降低,但氯离子有促进光合作用和纤维形成等作用对麻类等纤维作物施用尤为适宜尿基复合肥中的氮元素施入土壤后,需转化为氨态氮和硝态氮植物才能吸收因此在施用过程中,气温较低的地区应提前施入。

 

5The different methods of application

Sulfur based compound fertilizer can as base fertilizer, top application, seed fertilizer and top dressing; Chlorine compound fertilizer can as base fertilizer and top application,fertilizer and manure in the neutral soil and soil should be better to mix use with organic fertilizer, phosphate rock powder; In urea based compound fertilizer containing biuret, should be more attention firing the seedin the application process, and should be deep application of overlying soil to prevent ammonia losses.

Urea based compound fertilizer application scope decided by the containing of chloride ions or sulfur ions chloride ion containing application in according with chlorine based compound fertilizer, and sulphur containing fertilizer suitable scope in accordance with the applicable range of sulfur based compound fertilizer.

五、施用方法不同

  硫基复合肥可作基肥、追肥、种肥和根外追肥;氯基复合肥可作基肥和追肥,用基肥和种肥时在中性土壤和配性土壤上宜与有机肥、磷矿粉等配合混合使用尿基复合肥中含有缩二脲,在施用过程中,应注意烧苗,同时施用时要深施覆土,防止氨的损失。

尿基复合肥具体适用范围要看,肥料中是含有氯离子还是硫元素,如含有氯离子适用范围按照氯基复合肥,含有硫元素尿基复合肥适用范围按照硫基复合肥的适用范围。
