Abstract
本发明公开了一种中量元素玉米专用水溶肥及其制备方法，它由以下重量份原料制成：尿素50‑70份、硝酸铵11‑19份、磷酸二氢钾10‑18份、硫酸铵9‑15份、反应助剂10‑16份、硫酸镁9‑15份、硫酸钙4‑10份、氨基酸5‑9份、腐殖酸2‑6份、糖醇4‑8份、黄腐殖酸1‑5份、植物生长调节剂4‑8份、除草剂1‑5份、EDTA5‑9份；本水溶肥不仅能有效的解决土壤板结、土壤重金属污染的问题，还能起到抑制杂草生长改善种植环境，提高玉米长势的优点。The invention discloses a special water-soluble fertilizer for corn with medium elements and a preparation method thereof, which is prepared from the following raw materials in parts by weight: 50-70 parts of urea, 11-19 parts of ammonium nitrate, 10-18 parts of potassium dihydrogen phosphate, sulfuric acid 9-15 parts of ammonium, 10-16 parts of reaction aid, 9-15 parts of magnesium sulfate, 4-10 parts of calcium sulfate, 5-9 parts of amino acid, 2-6 parts of humic acid, 4-8 parts of sugar alcohol, yellow 1-5 parts of humic acid, 4-8 parts of plant growth regulator, 1-5 parts of herbicide, 5-9 parts of EDTA; this water-soluble fertilizer can not only effectively solve the problems of soil compaction and soil heavy metal pollution, but also play a role The advantages of inhibiting the growth of weeds, improving the planting environment and improving the growth of corn.
Description
技术领域technical field
本发明涉及肥料制备技术领域，具体涉及一种中量元素玉米专用水溶肥及其制备方法。The invention relates to the technical field of fertilizer preparation, in particular to a water-soluble fertilizer special for medium-element corn and a preparation method thereof.
背景技术Background technique
水溶性肥料，是一种可以完全溶于水的多元复合肥料，它能迅速地溶解于水中，更容易被作物吸收，而且其吸收利用率相对较高，更为关键的是它可以应用于喷滴灌等设施农业，实现水肥一体化，达到省水省肥省工的效能。Water-soluble fertilizer is a multi-component compound fertilizer that can be completely dissolved in water. It can be quickly dissolved in water and is more easily absorbed by crops, and its absorption and utilization rate is relatively high. More importantly, it can be applied to spray Facility agriculture such as drip irrigation realizes the integration of water and fertilizer, and achieves the efficiency of saving water, fertilizer and labor.
玉米是禾本科玉蜀黍属一年生草本植物。别名：玉蜀黍、棒子、包谷、包米、包粟、玉茭、苞米、珍珠米、苞芦、大芦粟，玉米总消费的在口粮比重大约在5％左右，但是随着时代的发展，这个比例有逐步降低的趋势。在“玉米的故乡”墨西哥，“国菜”玉米饼的年消耗量达到1200万吨之多；在发达国家和地区，玉米也被作为补充人体所必需的铁、镁等矿物质的来源为人们广泛食用；在某些贫困国家和地区，玉米依然是人们廉价的果腹之物，玉米虽然营养价值低于其他谷物，但是玉米里面可以提出异麦芽低聚糖，异麦芽低聚糖是益生元里最优异的，益生元是益生菌的粮食，对人体的益生菌繁殖有着密切的关系，从而对肠道菌群达到平衡状态，使得肠道健康，由于玉米具有较高的食用价值和药用价值，因此如何栽培出品质优良、营养丰富的健康玉米具有重要的意义，玉米的栽培其中最为重要的便是肥料的施用，其直接关系到玉米的长势、对养分的吸收以及对生长环境的需求，但是传统的肥料在施用过程中往往只能够保证作物的生长需求，无法解决由于施肥造成的营养元素利用不完善，导致土壤板结的问题，而且也无法解决土壤重金属污染、有毒有害物资污染的问题，由此可以看出如何研制出一种既能够提高营养元素利用率，又能够有效解决土壤板结、土壤重金属污染，改善土壤环境的问题的肥料是现代农业发展迫切需要的，为此，本发明人通过大量的实验和研究提供了一种中量元素玉米专用水溶肥及其制备方法。Corn is an annual herbaceous plant of the grass family Zea genus. Alias: corn, cob, corn, corn, millet, corn, corn, pearl rice, bract reed, big milo. The proportion of total corn consumption in rations is about 5%, but with the development of the times, this proportion has increased. gradually decreasing trend. In Mexico, the "hometown of corn", the annual consumption of "national dish" tortillas reaches as much as 12 million tons; in developed countries and regions, corn is also used as a source of iron, magnesium and other minerals necessary for the human body. It is widely eaten; in some poor countries and regions, corn is still a cheap food for people to eat. Although the nutritional value of corn is lower than that of other grains, isomaltooligosaccharides can be found in corn, which is a prebiotic Most excellently, prebiotics are the food of probiotics, which are closely related to the reproduction of probiotics in the human body, so as to achieve a balanced state of intestinal flora and make the intestinal tract healthy. Because corn has high edible value and medicinal value , so how to cultivate healthy corn with good quality and rich nutrition is of great significance. The most important thing in the cultivation of corn is the application of fertilizer, which is directly related to the growth of corn, the absorption of nutrients and the demand for the growth environment. However, traditional fertilizers can only ensure the growth needs of crops during the application process, and cannot solve the problem of soil compaction due to the imperfect use of nutrients caused by fertilization, and cannot solve the problems of soil heavy metal pollution and toxic and harmful substances pollution. It can be seen that how to develop a kind of fertilizer that can not only improve the utilization rate of nutrient elements, but also effectively solve the problems of soil compaction, soil heavy metal pollution, and improve the soil environment is urgently needed by modern agricultural development. For this reason, the inventors A special water-soluble fertilizer for middle element corn and a preparation method thereof are provided through a large number of experiments and researches.

下面结合具体实验例对本发明做进一步的说明：The present invention will be further described below in conjunction with specific experimental examples:
实验例1Experimental example 1
采用本发明实施例一、实施例二、实施例三、实施例四、实施例五、实施例六、实施例七、实施例八、实施例九制备出的水溶肥进行技术指标对比其结果如表1所示：Adopt the water-soluble fertilizer prepared by embodiment one, embodiment two, embodiment three, embodiment four, embodiment five, embodiment six, embodiment seven, embodiment eight, embodiment nine of the present invention to carry out technical index comparison and its result is as follows Table 1 shows:
表1本发明水溶肥技术指标对比结果Table 1 Water-soluble fertilizer technical index comparison result of the present invention
由上表可以看出，通过检测后本发明制备出的水溶肥完全符合标准，而且大量元素、中量元素的含量远远优于固定指标，水不溶物含量也很低，是一种水溶性极好的水溶肥。It can be seen from the above table that the water-soluble fertilizer prepared by the present invention fully complies with the standard after passing the test, and the content of major elements and medium elements is far better than the fixed index, and the content of water-insoluble matter is also very low. It is a water-soluble fertilizer. Excellent water soluble fertilizer.
实验例二Experimental example two
本水溶肥田间示范试验，实验田地处于贵州，气候温和，雨水充沛，采用每亩田地标号实验，一共选择10亩田地，采用常规施肥以及常规施肥+本实施例1-9制备出的水溶肥进行玉米栽培实验，实验结果如表2所示：In this water-soluble fertilizer field demonstration test, the experimental field is located in Guizhou, with a mild climate and abundant rainfall. The field label experiment per mu is used, and a total of 10 mu of fields are selected, and conventional fertilization and conventional fertilization + water-soluble fertilizers prepared in Examples 1-9 are used. Corn cultivation experiment, the experimental results are shown in Table 2:
表2水溶肥田间示范试验Table 2 Water-soluble fertilizer field demonstration test
由上可以看出采用常规施肥的方式进行玉米的种植其产量在理论值内，而采用常规施肥+本实施例1-9制备出的水溶肥进行玉米的种植其产量不仅高于理论值而且还远远高于单独采用常规施肥的，因此采用本发明进行玉米的种植是具有较高的增产效果的。It can be seen from the above that the yield of corn planted by conventional fertilization is within the theoretical value, while the yield of corn planted by conventional fertilization + water-soluble fertilizer prepared in Examples 1-9 is not only higher than the theoretical value but also higher than the theoretical value. Far higher than that of conventional fertilization alone, so adopting the present invention to plant corn has a higher yield-increasing effect.
实验例三Experimental example three
土壤重金属处理实验：Soil heavy metal treatment experiment:
以贵州省无污染的褐土为载体添加外源重金属污染物测其土层深度5-20cm处含Pb100mg/kg、Cd6mg/kg、Cr900mg/kg、Cu980mg/kg，将该土壤作为实验土壤，将本发明实施例中制备出的水溶肥投放入实验土壤中，15天后进行土壤土层深度5-20cm处重金属浓度检测，其检测结果如表3所示：Take the pollution-free cinnamon soil of Guizhou Province as the carrier to add exogenous heavy metal pollutants to measure the depth of the soil layer at 5-20cm to contain Pb100mg/kg, Cd6mg/kg, Cr900mg/kg, Cu980mg/kg, and use this soil as the experimental soil. The water-soluble fertilizer prepared in the embodiment of the present invention is put into the experimental soil, and after 15 days, the heavy metal concentration detection at the depth of 5-20 cm of the soil layer is carried out, and the detection results are as shown in Table 3:
表3土壤重金属处理实验结果Table 3 Experimental results of soil heavy metal treatment
由上可知，采用本发明实施例中制备出的水溶肥投放入实验土壤中15天后，土壤5-15cm处的重金属含量显著降低，说明了本水溶肥中含有的硫代硫化物与重金属离子发生反应生产沉淀，从而将重金属离子进行固定，阻止其通过淋溶和径流迁移，另外本水溶肥中的硫代硫化物还能将高价重金属离子还原成低价态，有效的降低其毒性和溶解性。As can be seen from the above, after the water-soluble fertilizer prepared in the examples of the present invention was put into the experimental soil for 15 days, the heavy metal content at the 5-15 cm place in the soil was significantly reduced, which shows that the thiosulfide contained in the water-soluble fertilizer and the heavy metal ion occur. Reaction produces precipitation, so as to fix heavy metal ions and prevent them from migrating through leaching and runoff. In addition, the thiosulfide in this water-soluble fertilizer can also reduce high-priced heavy metal ions to low-valent states, effectively reducing their toxicity and solubility. .
