Photosynthetic fertilizer - sodium bisulfite, which is neither chemically suitable, is not a chemical peony, and is not a plant growth hormone. However, when this non-fertilizer chemical is diluted with water, it is used for foliar application in the growing season of vegetables, but it can significantly increase the yield of vegetables. Local application shows that using photosynthetic one on vegetables can improve photosynthetic efficiency, promote growth and development, reduce nutrient consumption, increase dry matter accumulation, increase yield and increase income, and generally increase vegetable yield by 10%-30%.
First, the application range of photosynthetic fertilizers in eggplant, tomato, pepper, cucumber, melon, sage, kidney bean and other vegetables on the best application.
Second, the spraying concentration Photosynthetic fertilizer spraying concentration must be appropriate, the concentration is too low and too high to play a more effective yield. Generally it is suitable to use 3750 times - 5000 times.
Third, the spraying period Most of the solanaceous fruit is the result of flowering, it should be sprayed from the initial flowering period to the fruiting period, sprayed once every 10 days or so, a total of 3 times. Cabbage, cabbage and other packaged leafy vegetables, should be sprayed in the rosette period, a total of 2-3 sprays, 7-10 days apart. The radish is sprayed twice in the straight roots, separated by 7 days. Amaranth and celery should be sprayed once when the height of the rod is 8-10 cm. Cabbage and radish should be sprayed once in the flowering period and full bloom period. Generally, it should be sprayed at 2:5-5 pm on sunny days. After 6 hours of spraying, it should be sprayed once in the rain.
4. Matters needing attention Photosynthetic fertilizer is suitable for application in vegetable fields with high fertility and good growth. After spraying, water and fertilizer management should be strengthened. When dry, the pores on the leaves of vegetables are closed and unfavorable, so watering should be done first. Spray again afterwards; the solution should be sprayed on the same day to avoid oxidation and reduce efficiency.
