On June 15, 2019, the biogas slurry cultivation experiment project in deep cooperation between yinghua environmental subsidiary in leling, shandong province and college of agriculture, China agricultural university achieved a good harvest, and 20 mu of winter wheat ushered in its first harvest season.
Cooperate with China agricultural university to carry out the experiment project of recycling manure pollution
In recent years, yingherui environment has been providing professional equipment and operation services for the recycling of manure waste of jialinhe (shandong) animal husbandry co., LTD., a large dairy cattle breeding enterprise located in the central part of the north China plain. It can produce 1000 tons of anaerobic fermentation biogas slurry every day.This time, yingherui environment and college of agriculture of China agricultural university have conducted an in-depth cooperation experiment project, which is to return the biogas slurry generated by jialihe (shandong) animal husbandry to the field for planting winter wheat experimental field.
The ten controls were set up in the experimental field, and different biogas slurry and fertilizer were used together to verify the planting effect.In the process of wheat planting, biogas slurry was used for three times, respectively as the base fertilizer for one time and fertilizer for two times.Scientific mixing and proportioning can effectively ensure the even application of biogas slurry and promote the nutrients in biogas slurry to be used by crops directly to the root.The experimental results showed that the yield per mu using 20t biogas slurry could reach 1,150 kg, which could increase the yield by 9.75% compared with the single application of fertilizer. Meanwhile, the ripening time of wheat was shortened by 3 days, which gained precious time for the planting of corn.
The demonstration project of biogas slurry planting achieved a good harvest and promoted the development of green agriculture。
The demonstration field of biogas slurry planting is also being carried out simultaneously, while the experiment field of biogas slurry planting is being carried out.Dasun township is an ecological circular agricultural park, mainly growing wheat and corn.Under the influence of many years of thinking about using chemical fertilizer to plant crops in dashun township, for returning biogas slurry to the field, many farmers have doubts about the fertilizer effect of biogas slurry.However, after using biogas slurry for three times in the demonstration field, the planting effect of wheat with a yield of up to 1,200kg per mu was finally revealed, the farmers' initial skepticism was changed, and they agreed that these high-quality organic fertilizers could effectively replace fertilizers. They not only began to consult the use method of biogas slurry, but also helped publicize the use effect of biogas slurry.
According to calculation, the use of biogas slurry planting, each mu of farmland in the season will reduce 100-150 yuan of chemical fertilizer purchase, artificial fertilizer and other costs. According to the calculation of 4 mu of farmland per household, the farmers who use biogas slurry to return to the field can reduce the cost of chemical fertilizer and artificial fertilization by 400-600 yuan just for one season of wheat planting, greatly reducing the cost of agricultural production.
Why does biogas slurry increase production?
First of all, biogas slurry has a strong quick effect, high nutrient utilization rate and can be quickly absorbed and utilized by crops. At the same time, due to the high content of organic matter, stable fertilizer effect and long endurance, it has both quick effect and slow effect.
Through determination of biogas slurry nutrient, its nutrient content comprehensively, the main components of the biogas slurry in the fermentation process of including organic and inorganic salts (e.g., ammonium salt, sylvite, phosphate, etc.), trace elements (such as calcium, copper, iron, zinc, manganese, etc.) and various hydrolytic enzymes (such as cellulase, protease and amylase, etc.) and other soluble substances.
Content of amino acids in anaerobic fermentation biogas slurry (mg/L)
n addition, biogas slurry also contains some bioactive substances, which have physiological regulation effects on plants, and the species is quite complex.Such as amino acids (not less than 17, see chart), plant hormones (332 mu g/L indole acetic acid concentration, concentration of gibberellin GA4 quality 0.86 mu mass concentration of 1.47 g/L, GA19 mu mass concentration of 0.27 g/L, GA53 mu g/L, cytokinins iPR mass concentration 0.002 mu g/L, etc.), B vitamins, vitamin B12, etc.), antibiotics (polyene type) and cold resistant material (such as proline, linoleic acid and fulvic acid, etc.), etc.
"Green planting, planting and breeding, comprehensive utilization of agricultural wastes" is an agricultural production model advocated and encouraged by the state and agricultural departments. Yinghe rui environment promotes the utilization of livestock manure, which not only reduces the pollution of breeding, but also improves the soil, reduces the amount of agricultural fertilizer, improves the quality of agricultural products and the yield of land, and achieves the unity of social, ecological and economic benefits.
