Low-yield paddy field plow layer soil-modifying fertilizer

Abstract

The present invention discloses a modified soil organic fertilizer, which is developed for overcoming the low output because of the lacked nutrient in the cultivated crops. After being test in the fields such as rice, vegetable and watermelon, the effect for increasing the output is greater. The organic substance material prepared in the product is organic substance of regenerated castoff in the city and town environment; the utilization cost for the castoff is much lower that is good for environment protection. The weight ratio in the product is that: 30 percent of organic substance in the soil, 6 percent of inorganic nutrient (wherein 2.5 percent of nitrogen, 1.5 percent of phosphor and 2 percent of kalium), 5 percent of calcium (including chelated calcium, complexing calcium and ion calcium), 10 percent of silicon and 0.5 percent of magnesium, zinc, manganese, molybdenum and selenium and so on. The weight ratio of the other filling materials is 48.5 percent (used for cultivated level soil or coated soil).

Description

Technical field [0001] The invention relates to an organic fertilizer, which is an innovative organic fertilizer product formulated for improving the soil of the cultivated layer of low-yield paddy fields to improve yield and quality. technical background [0002] Fertilizers used on crops in my country are mainly chemical fertilizers, accounting for about 60%. From 1992 to 1997, the amount of chemical fertilizers applied was 2080-39.8 million tons (pure nutrients). Domestic chemical fertilizers accounted for 62.1-71.56%, which was significantly lower than 72.6-98.3% from 1979 to 1990. Due to the increase in the rotation index, the agricultural soil Increased consumption of organic matter is extremely detrimental to the sustainable development of agriculture. Of the 1.6 billion arable land in my country, two-thirds are low- and medium-yield fields, and the soil organic matter content is low. Only relying on the application of chemical fertilizers cannot meet the requirements of h...

Problems solved by technology

At present, about 80% of my country's agricultural cultivated land is deficient in nitrogen, 50% in phosphorus, and 30% in potassium. In some areas, the soil organic matter is less than 1%.

An important reason for this phenomenon is the excessive application of chemical fertilizers, which leads to the decline in the quality of cultivated land in the plow layer.
