Description

Use of bio-based sulfonates as a source of nutrients and conditioners Technical field

The invention belongs to the field of protection and application of bio-based sulfonate compositions, and particularly relates to the use of bio-based sulfonates as nutrient sources and conditioning agents, including applications for regulating plant and microbial growth environments.

Background technique

The existing desertified land area of the world is 36 million square kilometers, accounting for one quarter of the global land area. Sandstorms, droughts and soil erosion are severe in the world, and natural disasters are frequent. Desertification areas are also the areas with the most ecologically fragile and socially economically backward areas. Therefore, sand control and sand control work is important for maintaining regional ecological functions and sustainable economic and social development. Global significance.

The area of global saline soil (saline-alkali soil) is 95.6 million square kilometers. Soil salinization treatment can not always be effective for a single measure. It must be adapted to local conditions. It should be comprehensively controlled by water conservancy, physics, chemistry, biology and other measures. Water conservancy engineering technology is the foundation and soil improvement is the key and reasonable use is difficult.

At present, there are mainly physical improvements to the saline-alkali soil improvement technology at home and abroad, such as through land leveling, deep ploughing and drying, and timely loosening of soil; water conservancy improvement techniques, such as irrigation and drainage, irrigation and salt washing, underground salt discharge; chemical improvement, through Gypsum, phosphogypsum, superphosphate, humic acid, peat, coarse residue, etc.; biological improvement, planting rice, planting salt-tolerant plants, using microbial fertilizers, etc. Among the above various saline-alkali land treatment measures, the application of drainage and salt washing is a basic scheme, but there are series of problems such as large water consumption, large engineering investment, and high implementation cost.

Biomass resources such as cellulose, lignin, chitin, humic acid, protein, oil and fat are the most abundant and widely distributed, the most cost-effective and most degradable renewable biomass resources on the earth, accounting for the carbon content of the plant community. More than 60% of the plants produce about 1.5 x 10 ¹² tons of fiber per year through photosynthesis.

Due to the bottleneck of the conversion utilization technology, only 2.5% of the fibers are utilized through the regeneration route. The commonly used grass square or sand barrier sand fixing technology has a single function, high labor cost, and poor use effect cannot be widely promoted. The application of gypsum, phosphogypsum, superphosphate, straw, fly ash, humic acid and other substances for the improvement of saline-alkali soil is also mainly due to the large amount of salt. The salt per aquifer requires several tons of improver and more than 100 tons. The water has the problems of large water consumption, easy salt return, soil compaction, difficult biological growth, high transformation cost, poor transformation effect, etc., and also requires efficient and low-cost treatment.

Biomass is the most basic raw material for development and application potential. China produces a large amount of biomass waste of about 5 billion tons of crop straw, animal husbandry, forestry and processing industry. At present, the method of directly returning straw or converting into organic fertilizer to return to the field has the problems of refractory degradation, large dosage, low utilization of crops, and most of the consumption by microorganisms. The development and utilization of good plants, especially straw resources, to solve the water-soluble problem of plant resources is the focus of soil remediation and conditioning.

The application rate (50-100) Kg/mu planted oil sunflower and Sudan grass, sprayed After 30 days, samples were taken to determine the enzyme activity in the soil, and the soil data in the blank and other microbial saline-alkali improvement techniques were compared. The specific data is shown in Table 10:

Table 10 Biochemical data analysis of sunflower stalk fiber sulfate in saline soil

After applying the sunflower stalk fiber sulfate improver for one month, the soil calcium gluconate content (sucrose enzyme activity index) increased by 80%-140%, and 50-100Kg/mu sunflower stalk fiber sulfate was applied. The soil fertility of the Ammonium Phosphate (35 kg) improver exceeds the efficacy of the modifier of 500-1000 Kg/mu. In the severe saline-alkali soil, the enzyme content of the catalase was increased by 2 times compared with the control group, which proved that the sunflower stalk fiber sulfate improver promoted the soil bioactivity and the effect.

Example 8: Release of trace elements in soil/matrix

300g of distilled water was added to 200g soil/matrix/matrix, and the soil/substrate quality 1.6-3.0% solid content was used to add the amount of ammonium sulphate sulfonate prepared according to the preparation example. The soil was added to the soil/matrix in the comparative experiment. / 2.0% of EDTA or citric acid was stirred uniformly and soaked for about 24 hours to compare the extraction rate of nutrients in soil/matrix with ammonium sulfonate, EDTA and citric acid. After solid-liquid separation, the filtrate was made up to 500 ml, and then the content of calcium and magnesium in the solution was determined by chemical analysis. The content of P ₂ O ₅ , Fe, Cu, Zn and other elements in the filtrate was determined by the corresponding national standard. The experimental data show that the concentration of various nutrients in the soil/matrix of the sunflower sulphate sulfonate is sufficient to maintain the nutrient requirements of the plant, and can be used as an additive component of the controlled release fertilizer under the same amount of addition. The acid-soluble ammonium salt has the same solubility for P, Fe, Ca, Mg, Zn and other elements as EDTA and citric acid. Moreover, the production cost of sunflower sulphate ammonium salt is much lower than that of EDTA and citric acid, and it requires a large amount of use.
