AI Technical Summary

Problems solved by technology

Although peat and humic acid contain a large amount of humic acid, there are not many active ingredients in it, and the content of available nitrogen, phosphorus and potassium is low, which cannot quickly meet the needs of crop growth
Although the nutrients contained in liquid fertilizer can meet the needs, it is mainly used in the production of horticultural crops, and the large-scale use has low efficiency and high cost

Embodiment 1

[0028] Example 1: Add 50g of nutrient A to 1kg of soil. The content of each component is: weathered coal 60%, peat 20%, microbial mycorrhiza 20%, and the concentrations of N, P, and K elements are respectively N (300mg / kg) , P(50mg / kg)K(300mg / kg). The optimization of soil aggregates is remarkable, the free humic acid content increases by 45%, the plant grows vigorously, the root system is developed, the phosphorus element is fully absorbed, and the biomass increases by 40%.

Embodiment 2

[0029] Implementation example 2: Add 30g of nutrient A to 1kg of soil, the content of each component is: weathered coal 30%, peat 60%, microbial mycorrhiza 10%, the concentration of N, P, K elements are N (200mg / kg) , P(100mg / kg)K(200mg / kg). The free humic acid content increased by 30%. The plant's absorption of phosphorus is significantly enhanced, the phosphorus content in the plant is increased by 258%, the root system is developed, and the total length is increased by 32% compared with the control soil.

Embodiment 3

[0030] Implementation example 3: Add 50g of nutrient B50g to 1kg of soil, the content of each component is: weathered coal 80%, microbial mycorrhiza 20%, the concentration of N, P, K elements are respectively N (300mg / kg), P (50mg / kg) K (300 mg / kg). Compared with the plants with ordinary chemical fertilizers, the biomass increased by 30%.

Abstract

The present invention relates to a coal base nutrient agent for improving soil, belonging to the field of organic and inorganic composite fertilizer technology. Its composition includes (by wt%) 30%-70% of danty, 20%-60% of turf, 10%-30% of microbial fungus root and chemical reagent after which is added, its soil nutrient concentration includes N element 200-300 mg / kg, K element 200-300 mg / kg and p element 50-100 mg / kg. Said invention can raise capability of plant to absorb nutrients, can raise adverse resistance of plant and can obviously raise yield of crops.

Description

Technical field [0001] The invention belongs to the technical field of organic-inorganic compound fertilizers, and particularly relates to organic-inorganic compound fertilizers based on grass charcoal and weathered coal. Background technique [0002] At present, the main nutrients in agricultural production around the world are the application of chemical fertilizers. Although the application of chemical fertilizers can increase the nutrient content of the soil in a short period of time, the types of added nutrients are relatively small, mainly nitrogen, phosphorus, and potassium, and the increase in soil organic matter and trace elements is small. Although in some regions, including some parts of China, increased application of organic fertilizers and green manures has begun to be emphasized, the production of organic fertilizers and green manures has the disadvantages of small scale and difficulty in quality control. Peat (peat) and weathered coal are two important resources. ...
