Compound humic acid liquid fertilizer

Abstract

The invention relates to a compound humic acid liquid fertilizer which uses water as a solvent and comprises humic acid, abundant nutrients and a plant growth regulator. The compound humic acid liquid fertilizer is prepared from the following components in percentage by mass: 12-20% of fulvic acid, 10-15% of urea, 16-24% of potassium dihydrogen phosphate, 0.3-0.5% of compound sodium nitrophenolate, 0.3-0.5% of sodium naphthaleneacetate, 0.2-0.3% of sodium alginate, 2-2.5% of sucrose and the balance of water. Every mu of soil needs 250-300mL of stock solution, and the stock solution is dilutedby 80-100 times, and sprayed on the foliage or poured to the root. The field plot experiment on fertilizer efficiency indicates that by using the compound humic acid liquid fertilizer, the yield of Brassica chinensis is increased by 8-9%, the yield of rapes is increased by 7-8%, and the yield of strawberries is increased by 22.9%.

Description

1. Technical Field [0001] The invention relates to a fertilizer, in particular to a liquid fertilizer, specifically a compound humic acid liquid fertilizer. 2. Background technology [0002] Humic acid is a kind of complex natural polymer organic compound formed and accumulated by the remains of animals and plants, mainly plant remains through the decomposition and transformation of microorganisms and a series of geochemical processes. It does exist as a physical entity. About 400 million years ago, land plants began to accumulate. The amount of humic acid is astonishing, counting in trillions of tons. my country is extremely rich in hundreds of billions of tons of peat, lignite, and weathered coal that are rich in humic acid substances. [0003] People really know that humic acid was first extracted from peat in 1786 by German Achard. According to textual research, "Wujinsan" (a national protected variety of Chinese medicine, "Wujin" refers to humic acid) included in the book "...

Problems solved by technology

[0005] In the past 30 years, although my country's humic acid industry has made great progress, as a big country, first of all, it is a country with a large amount of agriculture and humic acid resources. The technology and application of humic acid are not suitable for the country's economic development and ecological construction in terms of depth and breadth. There is also a large gap compared with the level of some developed countries

[0009] Phosphorus is one of the three essential fertilizer elements for crop growth. my country is a large agricultural country, but it is also a country with a very short supply of phosphate rock resources per capita. According to relevant data, 80% of the available phosphorus is absorbed by soil Ca2+, Mg2+, Fe2+, Zn2+, AL3+ and other cations are fixed into insoluble phosphorus, and a large amount of ineffective phosphorus has been enriched in the soil for a long time. On the one hand, it will cause a lot of waste of soil fertilizer, and on the other hand, it will destroy the aggregate structure of the soil, resulting in soil compaction and quality decline. environmental pollution
