Description

Fertilizer for corn, green peppers and cabbage containing glycinebetaine and poly aspartic acid to reduce the use of fertilizer usage}

The present invention provides the effect of promoting the absorption of nutrients due to the ion adsorption capacity of the aspartic acid (PAA), an eco-friendly biodegradable polymer material, the effect of promoting muscle growth and the osmotic pressure of glycinebetaine, an environmental stress relieving agent. The present invention relates to an eco-friendly fertilizer for corn, pepper and cabbage that does not affect the yield or growth even when fertilizing less than the standard fertilizer required to grow corn, cabbage and pepper.

In terms of the use of chemical fertilizers in Korea, the amount of use per unit area decreases from 382 kg / ha in 2000 to 340 kg / ha in 2007 and 311 kg / ha in 2008, but is significantly higher than in other developed countries. .

Compared with OECD countries in 2001-2003, fertilizer consumption is 338 kg / ha in the UK, 227 kg / ha in France and 305 kg / ha in Japan, but Korea ranks fifth with 423 kg / ha. In the Environmental Sustainability Index (ESI), which is released every three to four years, Korea ranks low in the fertilizer sector, ranking 138th out of 146 countries. In addition, the continuous increase in farmland input of livestock manure, along with chemical fertilizers, has resulted in salt accumulation and surface water nutrient nourishment due to nutrient surplus, which is the highest nutrient index among OECD countries.

Nitrogen, one of the major components of fertilizers, is a nitrous oxide (N ₂ O), which has 310 times higher global warming effect than carbon dioxide among the six gases of climate warming (CO ₂ , CH ₄ , N ₂ O, HFC, PFC, SF ₆ ). It is an occurrence factor.

Recently, the United Nations Framework Convention on Climate Change is being promoted to prevent global warming due to global warming due to the increase of greenhouse gases.As part of this, Korea aims to reduce greenhouse gas emissions by 4% compared to 2005 by 2020. Came to announce.

However, commercial fertilizers in the market have a problem in that the growth or yield of crops decreases when the fertilizer is reduced below the standard fertilization rate.

On the other hand, as part of an attempt to improve the above problems for the environment, there is also an active research on a method of reducing the amount of chemical fertilizers to an optimal amount by improving various fertilizers put into farmland. In particular, much research has been made on the use of some organic acids, oligomers, etc. as chelating means that can promote the absorption of inorganic elements of plants.

Poly aspartic acid (PAA), a type of amino acid, is a peptide chain composed of amide bonds and is generally prepared by thermal polymerization of aspartic acid. Regarding the preparation of such polyaspartic acid, U.S. Pat.No.4839461, U.S. Pat.No.4590260, German Patent No.2253190, U.S. Pat.No.5057597, US Pat.No.5219952, U.S. Pat.No.5288783, Korean Patent No.10-0764933 It is already disclosed in the issue.

Such polyaspartic acid (PAA) is widely used as a water treatment agent or detergent builder by utilizing water retention and ionic bonding ability, but the method of using it in agriculture, especially in fertilizers, is not well known. In some cases, the use of polyaspartic acid (PAA) as a fertilizer is known to be considered as an environmentally friendly material that promotes growth, yield, and root development.

In relation to this, the known foreign publications or published in Korea have generally been inconvenient in the method of fertilizing by using polyaspartic acid alone or fertilizing with fertilizer. In particular, German Patent Application Publication No. 10008738 (August 30, 2001) does not calculate the appropriate content according to the type of fertilizer, and only the problem of excessive application by each species is expected by using polyaspartic acid as a fertilizer extensively. In addition, the effect was also not tested through the crop cultivation test, so there was a limit to the application to the crop. In addition, Korean Patent No. 10-0850186 (2008.07.28) obtains the optimum polyaspartic acid (PAA) content range according to each type of fertilizer to prevent excessive damage of polyaspartic acid (PAA), growth and yield through incorporation into fertilizer Only effects such as enhancement are known.

However, the addition of polyaspartic acid alone does not maximize the nutrient utilization efficiency of crops, so there is no way to drastically reduce the amount of fertilizer.

Therefore, the inventors of the present invention further utilize polyaspartic acid (PAA) in order to further utilize polyaspartic acid (PAA), sugars such as arabinose, polyhydric alcohols such as pinitol, proline or glycinebetaine. A study was made to reduce the amount of fertilizer used by increasing the absorption capacity of plants using osmotic pressure-controlled solutes of amino acids and derivatives thereof. Glycinebetaine lowers the osmotic potential in the cell, promotes water absorption, and increases the intracellular salt concentration to maintain homeostasis at the osmotic level when subjected to environmental stress (low temperature, high temperature, family crest, salt, etc.). It is well known as a substance that controls the osmotic pressure to maintain it.

As a result, the present inventors obtained the optimum content of polyaspartic acid and glycine betaine and the optimum fertilizer composition for each crop, and confirmed the effect of reducing fertilizer consumption through crop cultivation experiments, and by maximizing the nutrient use by optimizing the growth of horticultural crops We have developed fertilizers for corn, red pepper and cabbage that can reduce the amount of fertilizer and reduce problems such as environmental pollution and greenhouse gas generation by reducing fertilizer consumption.

An object of the present invention is to provide a fertilizer for corn, pepper and cabbage that can improve the problems such as environmental pollution or greenhouse gas generated by the fertilizer by reducing the amount of fertilizer without falling and growth of horticultural crops.
