Description
所属技术领域Technical field
本发明涉及一种多元素叶面肥。The invention relates to a multi-element foliage fertilizer.
背景技术Background technique
目前农业上应用的叶面肥种类繁多，从组成上一般分为激素类和营养类。现有技术中，营养类叶面肥主要是由大量营养元素氮、磷、钾以及多种中、微量元素组成，如中国专利申请CN1199724A、CN1163876A所公开的叶面肥。At present, there are many kinds of foliar fertilizers used in agriculture, which are generally divided into hormones and nutrients in terms of composition. In the prior art, nutritional foliar fertilizers are mainly composed of macronutrients nitrogen, phosphorus, potassium and various medium and trace elements, such as the foliar fertilizers disclosed in Chinese patent applications CN1199724A and CN1163876A.
但是，现有的营养类叶面肥一般氮磷钾养分偏低，且大多含有一些生长素或激素类物质，不太适合现代环保农业的需求。However, the existing nutritional foliar fertilizers are generally low in nitrogen, phosphorus and potassium nutrients, and most of them contain some auxin or hormone substances, which are not suitable for the needs of modern environmental protection agriculture.
发明内容Contents of the invention
本发明的目的是提供一种新型的多元素叶面肥，该叶面肥氮磷钾养分含量高，并辅以中微量元素，养分均衡全面，特别适合农作物对养分的需求。The purpose of the present invention is to provide a novel multi-element foliar fertilizer, which has high nutrient content of nitrogen, phosphorus and potassium, supplemented with medium and trace elements, has balanced and comprehensive nutrients, and is especially suitable for the nutrient requirements of crops.
本发明是这样实现的。本发明的多元素叶面肥的重量百分组成为：The present invention is achieved like this. The weight percent of multi-element foliage fertilizer of the present invention is composed of:
尿素 12～50wt％，Urea 12～50wt%,
磷酸一铵 15～40wt％，Monoammonium phosphate 15～40wt%,
聚磷酸盐 5～20wt％，Polyphosphate 5～20wt%,
氯化钾 25～34wt％，Potassium chloride 25～34wt%,
中微量元素 3～7wt％。Medium and trace elements 3～7wt%.
所述的中微量元素是硫酸锌、硼酸和混合微肥，其占叶面肥总重量的百分组成是：硫酸锌1.0～2.5wt％、硼酸1.0～2.5wt％、混合微肥1.0～2.0wt％，所述混合微肥是水溶性的镁、铜、铁、锰、锌、钼化合物。The medium and trace elements are zinc sulfate, boric acid and mixed micro-fertilizer, and its percentage composition accounting for the total weight of foliar fertilizer is: 1.0-2.5 wt% of zinc sulfate, 1.0-2.5 wt% of boric acid, 1.0-2.0 wt% of mixed micro-fertilizer % by weight, the mixed micronutrient fertilizer is a water-soluble magnesium, copper, iron, manganese, zinc, molybdenum compound.
所述的聚磷酸盐是聚磷酸铵、二聚磷酸铵、三聚磷酸盐、偏磷酸铵、焦磷酸铵、聚磷酸钾、偏磷酸钾、焦磷酸钾等。The polyphosphate is ammonium polyphosphate, ammonium dipolyphosphate, tripolyphosphate, ammonium metaphosphate, ammonium pyrophosphate, potassium polyphosphate, potassium metaphosphate, potassium pyrophosphate and the like.
一般微量元素与正磷酸盐结合时，产生的是非水溶性的盐类，不易被植物吸收。但聚磷酸具有螯合金属离子的特点，能与一些金属离子形成稳定性很强的络合物，使一些微量元素在常温下不易沉淀析出。施肥时溶液稳定，又保持了微量元素对作物有效的形态。所以，聚磷酸盐可以用作微量元素的载体，较之采用乙二胺四乙酸的金属盐作为微量元素的载体，价格低廉。再者，聚磷酸盐本身又是一种磷含量很高的肥料，固体聚磷酸铵一般含N 12％，P2O5 68％，作为叶面肥的组分之一，可以提高叶面肥的养分含量。Generally, when trace elements are combined with orthophosphate, water-insoluble salts are produced, which are not easily absorbed by plants. However, polyphosphoric acid has the characteristics of chelating metal ions, and can form highly stable complexes with some metal ions, so that some trace elements are not easy to precipitate at room temperature. When fertilizing, the solution is stable and maintains the effective form of trace elements for crops. Therefore, polyphosphate can be used as a carrier of trace elements, which is cheaper than using metal salts of ethylenediaminetetraacetic acid as a carrier of trace elements. Furthermore, polyphosphate itself is a fertilizer with high phosphorus content. Solid ammonium polyphosphate generally contains 12% N and 68 % P2O5 . As one of the components of foliar fertilizer, it can increase the nutrient content.
另外，聚磷酸盐作叶面喷施时，其浓度可以比正磷酸盐浓度高2～3倍，也不致造成叶片伤害，施用时安全可靠。利用叶面施肥浓度高这一特点，可以作为设施栽培后期追肥的重要手段。现在，一些经济作物的生产往往采用大棚栽培，产量高，品质好，但为保持作物的高产其施肥量也大幅度提高。由于大棚栽培减少了雨水对土壤的淋洗，使土壤的盐渍化程度提高，给作物的正常生长带来了危害，尤其对一些玻璃大棚，限制了其使用寿命。这样，如果减少作物基肥使用量，采用叶面追肥补充部分作物营养，无疑可降低土壤盐渍化的速度。而本发明的叶面肥氮磷钾大量元素的养分含量高，叶面喷施浓度高也不致造成叶面伤害这一特点，正适合这一需要。In addition, when polyphosphate is sprayed on the leaves, its concentration can be 2 to 3 times higher than that of orthophosphate, and it will not cause damage to the leaves. It is safe and reliable when applied. Utilizing the feature of high concentration of foliar fertilization, it can be used as an important means of topdressing in the later stage of protected cultivation. At present, the production of some economic crops is often cultivated in greenhouses, with high yield and good quality, but the amount of fertilizer applied is also greatly increased to maintain the high yield of crops. Because greenhouse cultivation reduces the leaching of rainwater to the soil, the degree of salinization of the soil is increased, which brings harm to the normal growth of crops, especially for some glass greenhouses, which limits its service life. In this way, if the use of crop base fertilizer is reduced and foliar topdressing is used to supplement part of crop nutrition, the speed of soil salinization can undoubtedly be reduced. However, the foliar fertilizer of the present invention has the characteristics of high nutrient content of nitrogen, phosphorus and potassium macroelements, and high foliar spraying concentration will not cause damage to the foliage, which is just suitable for this requirement.

采用本发明的叶面肥在农作物上的喷施试验：Adopt the spraying test of foliage fertilizer of the present invention on crops:
以叶面肥浓度为0.3～1.0％对草莓进行叶面喷施，在盛花结果期内喷肥1～2次，19个试验点平均可增产20％以上，改善了品质，大果率增加约30％，总糖也有明显增加。Spray strawberries with a concentration of 0.3-1.0% foliar fertilizer on the leaves, and spray fertilizer 1-2 times during the period of full flowering and fruiting. The 19 test points can increase the yield by more than 20% on average, improve the quality, and increase the rate of large fruit by about 30%, the total sugar also increased significantly.
以叶面肥浓度为0.3～0.7％对葡萄进行叶面喷施，在开花膨果期内喷肥3～4次，7个试验点平均可增产10％以上，水溶性总糖提高，酸度下降，糖酸比明显增加。Spray the leaves of grapes with a foliar fertilizer concentration of 0.3-0.7%, and spray fertilizer 3-4 times during the flowering and fruit swelling period, the average yield of the 7 test points can be increased by more than 10%, the total water-soluble sugar increases, and the acidity decreases , sugar-acid ratio increased significantly.
