How to fertilize vegetables on the balcony
With the rise of urban agriculture, growing vegetables on the balcony has become a new way for modern people to get close to nature. To achieve a bumper harvest in your own vegetable garden, scientific fertilization is the key link. Mastering the correct fertilization method can not only improve the quality of vegetables, but also avoid common problems such as seedling burning and soil hardening, making the planting process more convenient. The three core points of balcony vegetable fertilization are accurate dilution of liquid fertilizer 1. Liquid fertilizer must be diluted strictly at a ratio of 1:1000 before use. It is recommended to use a measuring cup to accurately match it. The concentration can be reduced to 1:1200 at high temperatures in summer to avoid evaporation and concentration and root damage. When spraying, the needle holds the nozzle 30cm away from the plant, and uses the atomization mode to evenly cover the leaves. 2 Self-made fertilizers such as rice washing water and peel enzyme need to be fermented for more than 30 days. EM bacteria can be added during fermentation to accelerate decomposition. It still needs to be diluted by 3 times during use, and solid fertilizer application should not exceed 2 times a week. Application specifications 1. Slow release fertilizer should be buried in a ring along the edge of the pot, 10-15cm away from the main root. Pottery pot planting requires a reduction of 20%, because clay has the characteristics of adsorption and fertilizer efficiency. 2. The eggshell fertilizer needs to be boiled and disinfected first, crushed to the size of rice grains, and then mixed with the substrate. Coffee grounds need to be composted for 2 weeks, and the monthly amount does not exceed 10% of the substrate. Base fertilizer and top dressing are combined. 1. Add 5g of decomposed sheep manure +3g of bone meal to each liter of substrate during planting to form a long-term nutrient bank. Leaf vegetables can increase the proportion of soybean cake fertilizer, while nightingans focus on phosphorus and potassium base fertilizers. 2. The topdressing cycle follows the "three-stage rule": seedling (mainly nitrogen fertilizer), flowering (mainly phosphorus fertilizer), and fruit stage (mainly potassium fertilizer). Root vegetables need to be added with plant ash extract during the expansion period. Special fertilizer application plan for solanies. Fine management of tomatoes/peppers need to be supplemented with potassium dihydrogen phosphate solution (1:1500) every week during the fruit setting period, combined with calcium and magnesium foliar fertilizer to prevent umbilical rot. It is recommended to use the "sandwich" fertilization method: bury fish intestines fertilizer at the bottom of the substrate, mix earthworm manure at the middle layer, and sprinkle rice hull charcoal on the surface layer. Nutritional control of carrot/radish Nitrogen fertilizer must be strictly controlled during the fleshy root formation period. Excessive application will lead to excessive stems and leaves. long. It is recommended to use a combination of plant ash (containing 35% potassium)+ calcium superphosphate (containing 12% phosphorus), and apply it once every 10 days. Scientific fertilization is the key to the success of balcony vegetable gardens. By mastering the characteristics of different fertilizers, growth stages and variety differences of vegetables, and combining regular observation of plant status adjustment plans, every urban farmer can harvest healthy vegetables with green colors. It is recommended to establish a fertilization log to record the time, type and effect of each fertilizer application, and gradually form a personalized fertilization system.
