Greenhouses are a special closed environment. Therefore, fertilization must be "eco-friendly" and "humanized". In this way, the longevity of greenhouses can be long-lasting and bring about continuous and efficient production performance and economic benefits. The greatest annoyance plaguing growers in greenhouses is the piles of rubbish in each season, which is not handled well. It is not only easy to infect germs but also pollutes the environment. Fertilizer-fertilizer, combined with other microbiological products such as fungus fertilizer, can form an ecological cycle mechanism for fertilizing greenhouses that are “taken from sheds and used in shedsâ€. This will not only harm but also benefit, beautify the environment and increase gains.
I. Fermentation Fertilizer is an effective measure to solve the troubles of greenhouses. Professional fertilizer starters are both environmental governance experts and soil improvement experts. Taking Kampo fertilizer starter as an example, it belongs to the domestic first natural compound fermentation bacterial agent, and is developed by using the latest international microbiological engineering technology. The production of ecological organic fertilizer with starter has the characteristics of fast fermentation, good fermentation, high-temperature fermentation, low-temperature fermentation, greatly shortening the production time, lowering costs, etc., as well as broad generality and adaptability, widely used. In the farm, greenhouse base, farmers market waste disposal and so on.
So, what is the difference between fermentation and non-fermentation, or addition of bacteria and traditional compost, and what characteristics does the fermented fertilizer have? The outstanding advantages of adding functional strain fermentation are mainly reflected in:
1, can remove bacteria. The traditional method of composting organic fertilizer contains a large number of bacteria, eggs, is the main source of infection of crop infections and insect pests. If the fertilizer is made from the Kimpo Fermenter, the fermentation temperature can be kept at 65 degrees or more for several days, so that all kinds of bacteria and eggs can be completely killed to prevent pests and diseases. 2, can avoid burning seedlings. Naturally fermented fertilizers are generally not thoroughly fermented, and they are also prone to burning roots. After fermentation, the fermentation is full and thorough and never burns. 3, can maintain points. The loss of nitrogen, phosphorus, potassium and other nutrients from natural fermentation is very serious, and the general utilization rate is only 30-40%. The use of goldfish fermentation agent treatment, the utilization rate of up to 95%. 4, can save time. Traditional soil composting takes too long, and some time-consuming one or two years. The treatment with the goldfish starter can be easily completed in 4-7 days. 5, can increase efficiency. Taking Jinbao starter as an example, 1 kg of fermentation auxiliaries will cost 40 yuan (typically a retail price of 35-50 yuan in the market) to ferment 3 tons of organic materials and produce superior organic fertilizers. Traditional composting may contain large amounts of pathogenic bacteria and viruses. Livestock and poultry manure that is not fermented and decomposed can be directly applied to greenhouses, which can lead to burning of roots and burning seedlings or diseases. The economic loss of the dead seeds and the increased cost of pesticides may be several times or several times the price of the starter itself. It does not take a year or two to cost.
Second, the fermentation method of fertilizer is simple and easy to operate to use a type of fermentation agent Jinbao example, according to 3 tons of material plus 1 kg of gold baby starter, the starter with 5 kg rice bran (or bran, corn flour and other substitutes ) Dilution and then evenly thrown into the heap, mixing and fermentation can be. During the fermentation process, proper oxygen supply and turnover were observed, and the temperature was controlled at about 70°C. The moisture content is controlled at about 65%. If the moisture content is too high, straw, sawdust, mushroom slag, dry earth powder, etc. can be added. The entire fermentation process is completed 5-7 days. The finished organic fertilizer is fluffy, dark brown, slightly scented or earthy, and nutritious.
3. Ecological Fertilization Examples in Greenhouses Ecological fertilization is actually a systematic project. Fermentation of organic manure is an important part of it. There are many other aspects that should be taken into account. The following describes the fertilization method for the whole growth period using eggplant as an example:
1, seeds. The fertilization of seeds is best done by dressing with microbial strains of bacteria. Fertilizer seed dressing can not only ensure the nutrient needed for seed germination, but also provide a good soil environment for the germination of seeds, which is conducive to raising seedling rate and cultivating strong seedlings. However, attention should be paid to the selection of quality qualified bacterial fertilizers. The technical background and technical sources are reliable, and the quality and performance are stable. For example, the stability of Kumba fungus fertilizer can be selected. Second, minimize the death of microorganisms. Fertilizer should avoid direct sunlight, and should be operated in the shade during seed dressing. Seed should be sowed immediately after dressing, and immediately cover soil. In addition, gold oyster root seedlings can also be used when seedlings or nursery seedlings are grown to make the seeds germinate quickly, with consistent emergence and no weak seedlings. 2, seedling period. Phosphate fertilizers applied at the seedling stage (mycorrhizal fungi can greatly increase the utilization of phosphate fertilizers) can lead to earlier results. 9 square meters of seedbed can be applied to 200 kg of fermented organic fertilizer, 0.5 kg of superphosphate and 0.5 mg of potassium sulfate; in the seedling stage (after 2 leaves and 1 heart), the use of gold treasure root seedlings can significantly promote the elongation of the main root, bold, lateral root Occurrence, increase root activity and absorption intensity, as soon as the formation of strong seedlings to facilitate transplanting. When the eggplant seedlings grow to 4 to 5 true leaves, they can be sprayed with 0.1% to 0.2% potassium dihydrogen phosphate or urea to ensure that they can grow strong seedlings. 3, basal fat. Apply 6,000 kg of organic fertilizer per 667 square meters. In old shed soil, nitrogen is surplus, phosphorus is enriched, and potassium is insufficient. 20 to 30 kg of potassium sulfate can be added. If it can be used in combination with 1-2 kilograms of Mushi's microbial microbial fertilizer, bacterial fertilizer not only contains a large amount of nitrogen-fixing, phosphate-releasing and potassium-releasing active bacteria, but also contains organic matter, humic acid and trace elements, which can not only save the use of fertilizers. Quantity, and can solve soil compaction, increase soil microbial content and other issues. 4, top dressing. When the “Dogella oleracea†reached the “open-eye periodâ€, the fruit began to grow rapidly. At this time, the fruit fertilizer was chase, 30-40 kg of ammonium sulfate per 667 square meters, or 15-20 kg of urea. Cover soil and water. When the fruit of “Tomato†is enlarged and the “Saimendou†begins to develop, it will catch fruit. With quick-acting nitrogen fertilizers as the main component and phosphorus and potash fertilizers, it is also necessary to pay attention to the application of medium-sized and trace element fertilizers such as calcium, boron and zinc on the foliage. In combination with watering, 1,000 kg of diluted dilute urine or 20-30 kg of diammonium phosphate is applied per 667 m2. After the second top-dressing and 10 days before the last harvest, when each layer of fruit begins to swell, it is chased once every 10 days or so and a total of 5-6 times of fat is recovered. Fertilizer and dilute urine are best used interchangeably. 5. Fertilizer outside roots: From the beginning of the fruiting period, fertilizers such as 0.2%-0.3% urea, 0.2%-0.3% potassium dihydrogen phosphate, and 0.1%-0.2% magnesium sulfate can be sprayed according to growing conditions. Usually 7-10 days, even spray 2-3 times.
In addition, the root can also be used to irrigate the root, which can significantly stimulate the occurrence and elongation of root systems at all levels, increase the absorption area and absorption strength of the root system, provide protection for the growth and development of the aboveground parts, and can also resist the weight loss. Effective control of rot, roots, dead seedlings, plant premature aging and so on. Through the above ecological fertilization, growers can obtain more ideal output, so as to increase production, improve quality and increase income, and at the same time extend the life of greenhouses, ensure the sustainable economic benefits, and achieve both ecological and environmental benefits.
