Detailed Explanation of Key Points of Fertilization Techniques for Autumn Chinese Cabbage
The autumn season for planting Chinese cabbage is coming around again. Some Chinese cabbage tastes bland, which is mainly caused by improper fertilization. How should fertilization be done so that the Chinese cabbage grows quickly and has good taste?
Preparation of base fertilizer? For each seedling, prepare 100 kg of calcium superphosphate, mix with 1000 kg of organic fertilizer, pile up for fermentation, and it must be composted and fermented 40 days before fertilization. 75 kg of 45% potassium sulfate compound fertilizer. For organic fertilizer, choose plant ash, cow manure, sheep manure, chicken manure, and straw, etc., but no matter what vegetable is being planted, pig manure cannot be used. If biogas fertilizer is available, that is even better.
Preparation of foliar fertilizer? There are hundreds to thousands of foliar fertilizers on the market now. Whichever one is chosen, use a foliar fertilizer that takes effect quickly, is green and environmentally friendly, and contains no hormones. No matter which foliar fertilizer it is, as long as it has a production license and fertilizer registration certificate, and has the above characteristics, it can be used.
Fertilization method? Evenly scatter the prepared base fertilizer on the field plot, then plow the field plot once more so that the base fertilizer and soil are fully mixed, then dig holes, place potassium sulfate compound fertilizer on one side of the hole, and plant Chinese cabbage on the other side, with a spacing of 7-10 cm in between. After planting the Chinese cabbage well, dilute plant high-grade nutrients with water at 1000-1500 times and water the root area, watering once every 3-5 days, for 3 consecutive applications. After the transplanted Chinese cabbage has fully revived and is in its rapid growth period, in order to make the Chinese cabbage grow quickly and ensure its quality, begin using water-soluble flush fertilizer. The specific method is: dilute the flush fertilizer with water at a concentration of 1%-2% and water the root area, watering the root area once every 7-10 days. For each season's growth cycle of Chinese cabbage, calculated according to the number of days for early-maturing, mid-maturing, and late-maturing growth, water once every 7-10 days. Each season requires multiple applications of flush fertilizer, but fertilization must be stopped 10 days before going to market. Jia Youjiang
