Double Economic Benefits of Applying Microbial Fertilizer to Corn

The level of soil fertility directly affects the yield increase and economic benefits of fertilizers. This article summarizes that on the basis of applying 5000 to 8000 kilograms of farmhouse fertilizer per mu of corn planting in the Heilongjiang region, the yield increase effect of adding bacterial fertilizer to medium fertility soil is greater than that of high fertility soil, and the economic benefits of fertilizer are also high. Therefore, in terms of fertilizer distribution, emphasis should be placed on plots with medium to low fertility levels. The results also indicate that maize responds significantly to nitrogen fertilizer and has varying degrees of yield increase effects on high or medium fertility soils. Phosphate fertilizer only has a certain yield increase effect on soil with an available phosphorus (P) content less than 5ppm; When it is greater than 10ppm, it also exhibits negative effects. Therefore, under certain agricultural production conditions, excessive emphasis should not be placed on blindly and extensively fertilizing to improve soil fertility levels. Instead, scientific fertilization should focus on improving the economic benefits of fertilizers, in order to achieve increased production and income.

Corn can be applied with * * microbial fertilizer, which can be used as both base fertilizer and topdressing. The specific usage is:

1.Base fertilizer: Apply 3000 kilograms of organic fertilizer per acre (you can choose Jinbao fertilizer fermentation agent to ferment and mature organic fertilizer for better results), and 2 kilograms of bacterial fertilizer. The fertilization method can be ditch or hole application, and an appropriate amount of nitrogen and phosphorus fertilizer can be combined according to the soil properties.

2. Topdressing: When the amount of fertilizer applied per acre is less than 20 kilograms of standard nitrogen fertilizer, it is advisable to apply the fertilizer once in the middle stage of jointing, and the stem and ear should be attacked together. Generally, early maturing varieties should be fertilized around 30 days after sowing, which is the "bell mouth period". About 25 days after sowing, it is best to apply fertilizer to medium ripe varieties. Late maturing varieties should be fertilized 35-4 days after sowing. If the application amount exceeds 20 kilograms of standard nitrogen fertilizer per mu, it is better to apply it in installments. The focus is on attacking the stem and panicle fertilizer. Generally, secondary topdressing is used in various regions, with the former being heavy and the latter being light. It is better to use 60% -70% of the stem fertilizer and 30% -40% of the ear fertilizer, and to spray trace amounts of zinc and boron during the jointing and booting stages.

Due to the presence of a large amount of beneficial bacteria in * * microbial fertilizer, after being applied to the soil, beneficial microorganisms rapidly multiply and diffuse in geometric order, as well as the metabolic products of functional microorganisms, such as super strong nitrogen fixation, phosphorus hydrolysis, and potassium hydrolysis, which can improve the physical and chemical properties of the soil, eliminate soil compaction, maintain nutrient balance, and reduce nutrient loss. * * microbial fertilizer also contains humic acid, organic matter, and various trace elements, It can stimulate the growth and development of crops such as corn, enhance its resistance to disease, drought, and cold, as well as enhance its resistance to stress and lodging. It also has a certain effect on the decomposition of pesticide residues and toxicity. It can also improve the utilization rate of chemical fertilizers and significantly reduce costs. * * Bacterial fertilizer can replace about 30% of chemical fertilizers, directly saving 500-800 yuan per mu of land, and increasing yield by over 200 kilograms per mu.
