Embodiment 1

[0019] Embodiment 1: The present invention is to the growth and soil influence of the cypress of different concentrations deicing agent processing

[0020] (1) The purpose of the experiment: to treat the rhizosphere soil of plants with polymer material water-retaining agent SAP, humic acid FA, and organic fertilizer OF (SFO), observe the plant growth effect after watering different concentrations of deicing agents, and analyze the promotion of greening by SFO Plant resistance to salt and alkali growth, and the effect of improving water and fertilizer use efficiency.

[0021] (2) Experimental materials and methods: Field plot experiments were used. Treatment design: according to the low concentration (30g / tree) and high concentration (100g / tree) of deicing agent (CaCl2, MgCl2, NaCl) and clear water (compared to CK), and the combination of three improved materials (water-retaining agent + organic fertilizer; water-retaining agent + humic acid; water retaining agent + organic fe...

example 2

[0034] Example 2: The present invention demonstrates the application of the soil anti-snow agent in the green belt of the expressway

[0035] (1) Actual test processing

[0036] a. The organic fertilizer is composted and fermented;

[0037] b. Mix humic acid, polymer material water retaining agent and organic fertilizer according to the ratio of 5:1:50, grind and mix well;

[0038] c. Make the finely ground and mixed fertilizer into balls or sticks.

[0039] On August 5, 2012, the soil in the green belt of Jingcheng Expressway (a large amount of chlorine-containing deicing agent was used in 2011) was used as the experimental object. 2 dosage application. Since plants have grown in the green belt, the specific method of fertilization is: open a circular ditch 5-10cm away from the root of each group of trees, the ditch width is 10-15cm, and the ditch depth is 10-25cm, and then the SFO compound water-retaining fertilizer is evenly applied, and then Soil compaction. Another c...

Abstract

The invention relates to a modification agent used for modifying soil, and especially relates to a snow-melting-agent-resistant soil-modification composite water-retention fertilizer. The fertilizer comprises, by weight: 4-6 parts of humic acid, 0.5-1.5 parts of a high-molecular-material water-retention agent, and 40-60 parts of an organic fertilizer. The organic fertilizer is prepared through microbe fermentation. The high-molecular-material water-retention agent is polyacrylate. Compared with prior art, the fertilizer provided by the invention has low cost, and assists in substantially ameliorating a soil salinization problem caused by snow-melting agent applciation. With the fertilizer, soil structure can be substantially improved, soil water retention can be enhanced, soil Na<+> and Cl<-> ion contents can be reduced, soil sodium adsorption ratio SAR can be reduced, the damage of the snow-melting agent upon soil and greening plants is reduced, highway greening plant growth and maintenance are facilitated, and great economic benefit can be provided.

Description

technical field [0001] The invention relates to a soil improving compound fertilizer, in particular to a soil improving compound water-retaining fertilizer which resists deicing agents. Background technique [0002] Ensuring the smooth flow of roads in winter snow is a major event in road maintenance, and deicing agent is the most commonly used method of melting ice and snow. For example, during the snowstorm in Beijing at night on November 4, 2012, more than 1,200 tons of snow-melting agent and more than 3,000 tons of snow-melting agent were scattered overnight in Beijing alone. [0003] There are two types of deicing agents: non-chlorinated and chlorine-containing. The non-chlorinated deicing agent has a better effect and basically no corrosion damage, but the price is higher; the chlorinated deicing agent (including sodium chloride, calcium chloride, Magnesium chloride, etc.) is used in large quantities due to its low price. However, the use of chlorine-containing deici...
