Corn syrup comes from corn and is a yellow-brown liquid.
1. Organic fertilizer and soil improvement
▪ Nutrient supplement: Corn syrup contains nitrogen, phosphorus, potassium and organic matter. It can be directly diluted and applied as liquid fertilizer to promote crop growth. It is especially suitable for leafy vegetables (such as spinach and lettuce) for rapid nutrient absorption.
▪ Microbial activator: As a carbon source and nitrogen source, it stimulates the reproduction of probiotics (such as actinomycetes and nitrogen-fixing bacteria) in the soil, accelerates the decomposition of organic waste such as straw, and improves soil fertility.
▪ Saline-alkali land improvement: Organic acids (such as lactic acid) in corn syrup can neutralize alkaline soil, reduce pH value, and improve salinized soil structure.
2. Seed treatment and seedling raising
▪ Seed soaking to promote germination: Diluted corn pulp is used to soak seeds (such as wheat and rice) to provide the nutrients required for germination, improve germination rate and uniformity of seedlings.
▪ Seedling substrate additive: Mix with vermiculite and perlite to make seedling substrate to enhance water retention and nutrient slow release effect.
3. Biological pesticide carrier
Fermentation substrate: Corn pulp is a high-quality substrate for microbial fermentation. It is used to produce biocontrol agents such as Bacillus subtilis and Trichoderma to inhibit soil-borne diseases (such as root rot).
1. Feed raw materials and attractants
▪ Protein and energy supplement: Corn pulp contains 20-30% soluble protein and sugars, which can be used as a cheap protein source for fish and shrimp feed, replacing part of fish meal and reducing feed costs.
▪ Attractant effect: The natural aroma of sugar and amino acids attracts fish and shrimp to eat, improves feed utilization, and is especially suitable for carnivorous fish (such as sea bass and mandarin fish).
▪ Fermented feed raw materials: mixed with soybean meal and bran for fermentation to produce probiotics and small peptides, which can enhance the intestinal health of aquatic animals.
2. Water quality control and algae cultivation
▪ Carbon source supplementation: Sprinkle corn slurry (1-2kg per mu) into the water body to provide carbon source for beneficial bacteria (such as nitrifying bacteria) and promote the degradation of ammonia nitrogen and nitrite.
▪ Plankton cultivation: As a component of the culture medium of rotifers and cladocerans, it can rapidly proliferate natural bait and reduce the cost of bait in the seedling stage.
3. Disease prevention and control
Immunity enhancement: β-glucan and vitamin B group in corn slurry can enhance the nonspecific immunity of fish and shrimp and reduce the occurrence of vibriosis and white spot syndrome.
1. Feed energy and protein supplement
▪ Liquid feed additive: directly add to drinking water or mix with feed (addition amount 3-5%) to provide easily digestible sugars and amino acids for pigs and poultry, especially suitable for fattening and lactating animals.
▪ Application in ruminants: corn slurry is mixed with urea to make a slow-release nitrogen source, which improves the efficiency of rumen microbial protein synthesis and increases the milk production of dairy cows or the daily weight gain of beef cattle.
2. Fermented feed and silage improvement
▪ Silage additives: corn slurry contains natural substrates for lactic acid bacteria, which can accelerate silage fermentation, reduce pH, inhibit spoilage bacteria, and improve the quality of silage (such as corn straw silage).
▪ Solid fermentation substrate: mixed with bean dregs and distiller's grains to produce high-protein feed, degrade anti-nutritional factors (such as trypsin inhibitors), and improve nutritional value.
3. Intestinal health and environmental emission reduction
▪ Prebiotic effect: Oligosaccharides in corn slurry promote the proliferation of intestinal lactic acid bacteria and reduce the diarrhea rate of livestock and poultry (such as weaning stress in piglets).
▪ Manure treatment: Feed with corn slurry can reduce ammonia emissions in manure, and at the same time, it can be used as a fermentation promoter for manure composting to accelerate the decomposition of organic matter.
1. Concentration control:
Agriculture: Foliar spraying needs to be diluted 10-20 times to avoid leaf burning due to high concentration.
Aquaculture: Excessive spraying may cause eutrophication of water bodies and trigger algae outbreaks.
Animal husbandry: Adding more than 8% may cause diarrhea in animals and require gradual domestication.
