The dominant species of vegetables planted in Dahe District Station in Luquan District of Shijiazhuang City is greenhouse cucumbers. In order to further improve the yield, quality, and benefits of cucumber, and effectively implement the source control of safe production, we introduced five-color soil bio-fertilizer to carry out experiments, demonstrations, and related The promotion of applied technology reserves the feasibility basis in practice. The ultimate goal is to improve the soil, promote the fitness cultivation of vegetables, reduce non-point source pollution in the production environment, and promote vegetable farmers to increase their incomes.
Several years of practical application show that the application of the five-color soil biofungicide can fully activate the release of large and medium-sized micronutrients in the soil, reduce chemical fertilizer fixation, significantly improve fertility, provide stable and balanced nutrition for crops, and increase the value of beneficial bacteria in soil. , produce a variety of activating substances, promote crop growth and development. After applying cucumber in the greenhouse, the developed roots, increased capillary roots, lateral roots, and deep roots increased the ability of the root system to absorb, transport, and conduct various nutrients and moisture. The thick green leaves, thick leaves, and light and efficiency were significantly enhanced; beneficial microorganisms were used. The role of effective suppression of a variety of soil-borne diseases, a fundamental solution to the continuous cropping caused by cucumber problems, reduce the incidence of yellow wilt disease, root rot disease. The introduction of five-color soil bio-fertilizer, promote the replacement of vegetable and fertilizer, and lay a solid foundation for the development of pollution-free vegetables in the area.
Five colored soil specific application measures: 1, seedbed treatment: 400 grams of colored soil mix 1 cubic seedbed soil. 2. Foliage spray and root irrigation at the seedling stage: spraying once every 10 days, using 50 g of colored soil to dilute 100 pounds of water, spraying directly on the front and back of the blade and evenly at the root. 3. Daejeon Soil Treatment: Settlement began in mid-September, applying 6-8 decomposed chicken droppings per acre, applying 400 g/mu of colored earth, 25 kg/mu of potassium sulfate, 75 kg/mu of superphosphate, and mixing. Spreading, leveling after deep turning. 4, after planting growth period and flush with fertilizer. During the growth period, five colored soils and red fertilization were applied, and each time fertilization was applied twice, the five-color soil fertilization was applied once. 5, the use of methods and times. Application method: flushing. Application period: seedling stage, early flowering stage, early fruit stage, full fruit stage. Specific operations: 1 seedling stage: 200g/mu watered 100kg planting hole irrigation root; 2 early flowering period: 300g/mu with water flushing; 3 early fruit period: 400g/mu with water flushing; 4 full fruit period: every Once in 30 days, 400g/mu will be flushed with water.
