Summer and autumn tube sheds forget about biological fertilizer

<

Summer and autumn festival management of shed vegetables, due to the use of chemical fertilizers for many years and neglect of biological fertilizers, increased the amount of fungicides, resulting in soil compaction, increased disease, reduced input-output ratio. Therefore, it is necessary to increase biological fertilizer.

1. Large ridge tillage cultivator: cultivating loose soil and using organic bio-fertilizer to increase soil fertility and soil permeability. Roots can reduce plant growth potential, promote root barb, reduce rot roots, and reduce long-term fertilization. The surface salt damage caused.

2. Irrigation of roots in plants: Solanaceous vegetables often die from diseases such as root rot, wilt, Verticillium wilt, and bacterial wilt. Irrigation of organic duodenal organic humic acid liquid fertilizer or amino acid liquid fertilizer can effectively degrade salt and salt, and inhibit diseases. In addition, cultivating soil is conducive to the growth of the stem and prolong the result period.

3. Remove old leaves: Solanum, melons, legumes, etc. Removal of old leaves and diseased leaves can reduce nutrient loss and reduce pests and diseases.

4. Intensive plant nutrition: Foliage spraying guateng fruit 2116 or Nongxiang source, plus potassium dihydrogen phosphate, direct supply of leaf nutrition, enhance the accumulation of photosynthetic production, increase production.

5. Regular prevention and control of diseases: In summer and autumn, the plants grow rapidly and produce high yields. However, under the influence of a high-humidity environment, Phytophthora infestans have developed rapidly and spread rapidly. Therefore, it is necessary to strengthen the prevention of diseases.

6. Addition of bio-organic fertilizer: The registration and promotion technology of bio-organic fertilizer has gradually matured and it has been approved by farmers. However, many farmers still believe that the output of shed vegetables is high and the benefits are good. Potassium, calcium, and trace fertilizer are the most important. ". Regardless of top-dressing or red-fertilizer, high-nitrogen and high-potassium compound fertilizers are mainly used. In fact, the old vegetable fields cultivated for many years have accumulated a large amount of inorganic salts, and only biological fertilizers (such as phosphorus lysis bacteria, potassium bacteriolysis bacteria, silicate bacteria, actinomycetes, and chelicillins, etc.) can decompose salt and improve Fertilizer effect, reduce costs, improve the quality of fruits and vegetables. Bio-fertilizer can improve soil, and organic fertilizer can fertilize soil. According to different crops and fertilizers applied at different growth stages, high-yield, high-quality, and high-efficiency can be achieved. During this period, due to the high ground temperature and high temperature, the soil has a long period of salt return to alkali, and it is necessary to top-up or flush bio-fertilizer or active fertilization.

7. Ventilation, moisture removal and heat preservation: According to the weather and crop growth, measures such as early-sealing air outlet, late air outlet, half-night air release, and other measures are taken to promote the accumulation of nutrients. Because this half-hour high carbon dioxide content in the air and the outdoor temperature is lower, it is easy to remove humidity and reduce air temperature.
