Soybean, one of China's economic crops, is naturally and is a species that many growers and farmers choose to grow. So the high-yield and high-yield fertilizer is organic fertilizer. The following is the application of organic fertilizer to soybeans. Good and impact, you have a quick look!
Organic fertilizers are mainly derived from plants and/or animals, and are applied to the soil to provide nutrients to plants. It is processed by biological materials, animal and plant wastes and plant residues, and eliminates toxic and harmful substances. It is rich in a lot of beneficial substances, including: a variety of organic acids, peptides and rich in nitrogen, phosphorus and potassium. Nutritional elements. It not only provides comprehensive nutrition for crops, but also has long fertilizer efficiency, can increase and update soil organic matter, promote microbial reproduction, improve soil physical and chemical properties and biological activity, and is the main nutrient for green food and organic food production. It is generally divided into farmyard manure, green manure and humic acid fertilizer. At present, the commonly used species in soybean production is bio-organic fertilizer.
1 Effect of organic fertilizer on soybean yield
Organic fertilizer has a significant effect on soybean yield increase. In 1998, Meng Jun et al reported that the application of organic fertilizer was beneficial to increase soybean yield, and proposed conditions for improving the utilization rate of organic fertilizer and improving the application method of soybean yield. Ma Zhijun et al reported that the application of humic acid organic fertilizer increased the yield and the yield increased. Tai Lianmei et al reported that under the condition of continuous cropping soybeans, three kinds of farm organic fertilizers (pig manure, chicken manure, and sheep manure) were applied for two years. The test results showed that the yield of applied organic fertilizer was higher than that of the control area. Luo Lianguang et al reported that rare earth bio-organic fertilizer can increase the number of soybean root nodules and increase the yield components such as soybean number, number of pods per plant and number of grains per plant, thus significantly increasing soybean yield. Sun Junhua et al reported that MI bio-organic fertilizer has a significant effect on increasing yield and increasing efficiency compared with conventional fertilizer. Sheng Dexian and other applications of tobacco straw bio-organic fertilizer as a base fertilizer can promote the dwarfing of soybean plants and the number of pods, and the effect of increasing yield is significant.
Studies have shown that the combined application of organic fertilizer and chemical fertilizer has the best effect. Lu Xianchun and others believe that the application of bio-organic fertilizer on soybean can promote the nodulation and nitrogen fixation of soybean roots, and the rational application of bio-organic fertilizer and chemical fertilizer can significantly improve Economic benefits. Zhu Baoguo and other reports, the application rate of organic fertilizer is not higher, the higher the soybean yield, and the highest proportion of chemical fertilizer application. Li Yuanming and others believe that the application of bio-fertilizer and chemical fertilizer in the soybean hectare is applied in a certain proportion (375 kg of biological fertilizer, 90 kg of diammonium phosphate, 37.5 kg of urea, 37.5 kg of potassium sulfate), and the yield increase effect is remarkable. With the continuous development of research and development, the types of organic fertilizers are also more abundant. Multi-functional organic fertilizers and peptide active organic fertilizers are also used in production. Wang Hongjun et al reported the application of bio-organic fertilizer, multifunctional organic fertilizer and peptide active organic fertilizer. These three kinds of organic fertilizers can increase the number of pods, the number of grains and the weight of one hundred seeds, and have obvious effects on soybean yield.
2 Effect of organic fertilizer on soybean quality
Studies have shown that the application of organic fertilizers helps to increase the total protein and fat content of soybeans. Zhu Baoguo et al reported that the higher the proportion of organic fertilizers and fertilizers, the higher the total amount of soy protein and fat content [8]. Li Minglei and others believe that bio-organic fertilizer and fertilizer increase the yield, but can significantly improve the quality of soybeans. Zhu Baoguo and other four fertilizers were tested by conventional fertilization, organic fertilizer, controlled release urea and controlled release compound fertilizer. Compared with no fertilizer application, different fertilizers could improve the quality of soybean seeds, but the treatment of soybean grain protein increased most was organic fertilizer treatment. .
3 Effect of organic fertilizer on soybean rhizosphere soil
Studies have shown that long-term application of organic fertilizer or organic and inorganic fertilizers can change the number of soil microbes and increase the number of bacteria, fungi and actinomycetes in the soil. In 2012, Tali reported the application of organic manure from cow dung. During the whole growth period, the number of bacteria and actinomycetes increased compared with the application of chemical fertilizers. The number of fungi decreased, but in flowering, pod-forming and maturity stages. The phase reduction is different. Zhang Jing et al. combined the decomposed chicken manure organic fertilizer with three kinds of biocontrol bacteria, such as Bacillus subtilis, Bacillus megaterium and Bacillus licheniformis, to prepare bio-organic fertilizer. The results showed that after applying bio-organic fertilizer, soil urease and phosphatase Soil enzyme activities such as catalase and invertase have been improved, and disease prevention and growth promotion effects are good.
4 Outlook
Organic fertilizer can improve soil physical and chemical properties, increase soil beneficial microbial content, promote soybean root development, increase yield and quality, and is an important fertilizer source for safe and efficient fertilization. The development trend of China's modern agriculture is sustainable development of agriculture. The development and utilization of bio-organic fertilizers in organic fertilizers will become a hot spot in the development of the fertilizer industry. The development of bio-organic fertilizers is also one of the necessary conditions for the development of the soybean industry towards green and organic cultivation.
In the future, straw returning will be one of the important ways to develop bio-organic fertilizer. Straw returning can improve soil, improve soil permeability, increase microbial content, increase organic matter content, reduce disease occurrence, and make full use of crop residues to avoid Incineration of straw causes environmental pollution, which not only protects the environment, but also saves costs and increases efficiency.
In fact, organic fertilizer has a lot of benefits for soybeans, which can not only achieve better quality of planted soybeans, but also improve soil nutrition. The above is the analysis of the effect of organic fertilizer on soybeans!
