It is now time for the cultivation of agricultural sheds in autumn. Many peasants still have some problems in management. According to the successful experiences of some agricultural experts and growers, the author briefly describes the management techniques of autumn shed vegetables for reference.
1. Large ridge tillage cultivator: cultivating loose soil combined with application of active organic fertilizer can improve soil fertility, soil permeability, reduce plant growth potential, promote root barb, reduce decay roots, and reduce the result of long-term fertilization of fertilizer material. Surface salt damage.
2. Irrigation of roots in plants: Solanaceous vegetables often die due to rhizome stem rot, withered, yellow wilt, blue-green and other diseases. Applying organic humic acid liquid fertilizer or chitin to fertilize can effectively degrade the salt and damage the disease. In addition, it is advantageous to cultivate roots in the stem and extend the fruiting period.
3. Remove the old leaves, diseased leaves: Solanum, melons, beans, etc., removal of old leaf disease leaves is an effective method to reduce plant nutrient loss, reduce disease, pests.
4. Apply foliar fertilizer: foliar spray of high-concentration amino acids, humic acid foliar fertilizer, can directly supply leaf nutrients, increase the accumulation of photosynthesis, can increase production.
5. Regular prevention and treatment of “epidemic diseasesâ€: autumn shed vegetables, plants are growing rapidly, and yields are high. However, due to the "high temperature and high humidity" environment, Phytophthora infestans has developed rapidly and spread rapidly, and it is necessary to strengthen the prevention of "epidemic diseases."
6. Increased bio-organic fertilizer: Many farmers believe that "high yields of sauerkraut are the most important factors for potassium-calcium phosphate fertilizer." Therefore, regardless of top dressing or flushing, high-nitrogen and high-potassium compound fertilizers are mainly used. In fact, the old sheds cultivated for many years have accumulated a large amount of inorganic salts, and only biological fertilizers (such as phosphorus-solubilizing bacteria, potassium-releasing bacteria, actinomycetes, etc.) can decompose salt damage, increase fertilizer, and improve the quality of fruits and vegetables. As the saying goes: Farming does not apply manure, equal to smashing. Bio-fertilizer can improve the soil, and organic fertilizer can fertilize the soil. According to different crops, different fertilizers can be applied at different growth stages to produce high yield, quality, and efficiency. Due to the high ground temperature and high humidity in the autumn greenhouses, the soil will rise back to alkali due to the damage of salt, and it is necessary to apply topdressing or flushing bio-organic fertilizer or a gallium bio-fertilizer.
7. Ventilation, humidification and cooling: Take weather, crops, growth and other measures to take early clearance, late opening, midnight release half an hour and other measures to promote nutrient accumulation. Because this half-hour high carbon dioxide content in the air, and the outdoor temperature is low, it is easy to reduce the temperature and humidity within the shed.
