Description
技术领域
本发明涉及农业技术领域,具体的,涉及一种增产硅碳螯合剂的制备方法和应用。
背景技术
螯合剂是一种广泛应用于农业、医药、环保等领域的化学物质。在农业领域中,螯合剂可以提高土壤中的微量元素利用率,促进植物生长和增产。目前市场上已有多种螯合剂产品,但是它们的效果有限,且存在一些问题,如溶解度低、稳定性差、毒性大等。
当今,农业生产中,土壤中的微量元素对植物的生长和发育起着至关重要的作用。然而,由于土壤中微量元素的含量较低,且不易被植物吸收利用,导致植物生长缓慢,产量低下,品质下降。因此,研发一种高效的螯合剂,提高土壤中微量元素的利用率,成为了农业领域的热门研究方向。
发明内容
本发明提出一种增产硅碳螯合剂的制备方法和应用,解决了相关技术中的螯合剂对提高土壤中的微量元素利用率有待提高的问题。
本发明的技术方案如下:
一种增产硅碳螯合剂的制备方法,包括以下步骤:
S1、向碳材料中加入水和含硅有机助剂加热至40-50℃;
S2、加入乙二胺二邻苯基乙酸钠、2-膦酸丁烷-1,2,4-三羧酸,加热至60-80℃;
S3、继续加入苹果酸和蛭石,降温至40-50℃,离心得到螯合剂。
作为进一步的技术方案,所述含硅有机助剂包括质量比为1:(2-3)的四(2-羟基乙氧基)硅烷和硅烷偶联剂KH-570。
作为进一步的技术方案,所述碳材料包括草本泥炭或藓类泥炭。
作为进一步的技术方案,所述碳材料、水、含硅有机助剂的质量比为1:(2-3):(0.2-0.3)。
作为进一步的技术方案,所述碳材料、乙二胺二邻苯基乙酸钠、2-膦酸丁烷-1,2,4-三羧酸的质量比为1:(0.4-0.6):(0.5-0.8)。
作为进一步的技术方案,所述乙二胺二邻苯基乙酸钠的质量小于2-膦酸丁烷-1,2,4-三羧酸。
作为进一步的技术方案,所述碳材料与苹果酸和蛭石的质量比为1:(0.1-0.2):(0.05-0.1)。
作为进一步的技术方案,所述的增产硅碳螯合剂的制备方法,包括以下步骤:
S1、向碳材料中加入水和含硅有机助剂加热至40-50℃,保温搅拌30min;
S2、加入乙二胺二邻苯基乙酸钠、2-膦酸丁烷-1,2,4-三羧酸,加热至60-80℃,保温搅拌1-2h;
S3、继续加入苹果酸和蛭石,降温至40-50℃,保温搅拌1-2h,干燥得到螯合剂。
本发明还提出了一种增产硅碳螯合剂,按照所述的制备方法得到。
本发明还提出了所述增产硅碳螯合剂在肥料中的应用。
本发明的工作原理及有益效果为:
1、本发明中的螯合剂能够促进根系生长,增加根系表面积,从而增加植物对营养元素的吸收,提高肥料利用率,还能够改善土壤结构和质量,增加土壤肥力,提高土壤保水能力和通气性,促进植物生长。本发明的螯合剂与常规的肥料共同施用于作物中,能够大幅度提高农作物产量,提高作物甜度,还能够起到增加VC含量的作用。
2、本发明通过EDDHA-Na和PBTCA配合含硅有机助剂对泥炭进行回收和提取,EDDHA-Na和PBTCA中含有多个亲水基团,能够与金属离子形成稳定的环状网络立体结构,能够提取出泥炭中的有机质和微量元素,还能够补充土壤腐植酸,增加土壤生命力,提高农作物果实的品质和口感。而且由于EDDHA-Na和PBTCA的用量比较大,还可以用于螯合肥料中的金属元素,提高肥料利用率。
3、本发明中的含硅有机助剂不仅能够促进EDDHA-Na和PBTCA对泥炭中有益成分的提取,但是EDDHA-Na的溶解度较差,本发明还通过含硅助剂和PBTCA两个层次提高其在水中的溶解度,保证施用时的扩散性。

S2、加入50份乙二胺二邻苯基乙酸钠、60份2-膦酸丁烷-1,2,4-三羧酸,加热至80℃,保温搅拌1h;
S3、继续加入15份苹果酸和8份蛭石,降温至50℃,保温搅拌1h,离心,收集液体干燥得到螯合剂。
实施例4
一种增产硅碳螯合剂的制备方法:
S1、向100份藓类泥炭中加入200份水和20份含硅有机助剂加热至40℃,保温搅拌30min;其中含硅有机助剂为质量比为1:2的四(2-羟基乙氧基)硅烷和硅烷偶联剂KH-570;
S2、加入45份乙二胺二邻苯基乙酸钠、45份2-膦酸丁烷-1,2,4-三羧酸,加热至60℃,保温搅拌2h;
S3、继续加入10份苹果酸和5份蛭石,降温至40℃,保温搅拌2h,离心,收集液体干燥得到螯合剂。
对比例1
一种增产硅碳螯合剂的制备方法:
S1、向100份藓类泥炭中加入200份水、40份乙二胺二邻苯基乙酸钠、50份2-膦酸丁烷-1,2,4-三羧酸,加热至60℃,保温搅拌2h;
S2、继续加入10份苹果酸和5份蛭石,降温至40℃,保温搅拌2h,离心,收集液体干燥得到螯合剂。
对比例2
与实施例1相比,含硅有机助剂为四(2-羟基乙氧基)硅烷,其他与实施例1相同。
对比例3
与实施例1相比,含硅有机助剂为硅烷偶联剂KH-570,其他与实施例1相同。
试验例
将实施例和对比例制备得到的螯合剂与以下组分混合,制备成肥料:
螯合剂10份、重钙20份、尿素50份、硫酸铵12份、黄腐酸10份、氯化钾或硫酸钾18份。
2022年,在邯郸市曲周县选取试验田7组种植小白菜,每组实验田种植条件均相同,其中试验田1-7分别施用本发明的实施例1-4、对比例1-3制备得到的肥料,不施肥。每亩用量30kg,用水稀释100倍后施入土壤。
成熟后测试VC含量和可溶性糖含量:每组试验田随机抽取100个小白菜叶片求平均值。
表1 试验田种植小白菜结果
本发明得到的螯合剂用于肥料中,促进吸收,能够促使作物产量大幅增加,增加糖度,提高作物VC含量。其中,实施例4相比于实施例1,产量有所下降,但是相比于对比例产量仍然较高。对比例1中没有添加含硅助剂,对比例2和对比例3中都仅仅添加一种含硅助剂,得到的螯合剂的使用效果均不如实施例1,本发明发现同时使用四(2-羟基乙氧基)硅烷和硅烷偶联剂KH-570两种助剂能够最大程度的提高肥料利用率。
以上仅为本发明的较佳实施例而已,并不用以限制本发明,凡在本发明的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本发明的保护范围之内。
