Four kinds of vegetables should not be fertilized

First, fresh manure should not be directly applied to vegetables. Fresh human waste contains large amounts of bacteria, toxins, and parasite eggs. If it is not directly cooked, it can contaminate vegetables and cause disease to enter the mouth. It can only be applied after high-temperature heaping fermentation or harmless treatment. Second, unfamed livestock and poultry manure will produce a large amount of harmful gases such as hydrogen sulfide during the decay process, which will easily make vegetables seeds suffocate due to lack of oxygen; in addition, a large amount of calories will easily cause vegetable seeds to burn or root rot, which is not conducive to vegetables. The seeds germinate and grow. Third, nitrogen fertilizer should not be applied to legumes. Root nodules of bean vegetables can fix nitrogen on their own, and excessive application of nitrogen fertilizer not only wastes fertilizer, inhibits root nodule activity, and reduces nitrogen fixation, but also makes them prolonged stems and leaves, lowering yield and affecting quality. Fourth, the use of chlorinated fertilizer should not be used excessively, excessive application of leaf (stem) vegetables (spray) potassium chloride, etc., not only make vegetables not fresh, fiber, and make the water taste of vegetables become bitter, poor taste, low efficiency.
