In general, fertilizers suitable for acupuncture at the time of colonization of vegetables include commodity organic fertilizers, biological fertilizers, humic acids, and amino acid fertilizers. These fertilizers are generally not easy to burn roots, and contain a wide range of nutrients, which are conducive to the extension of seedling roots. It is advisable to apply 30 to 40 grams into the hole. Compound fertilizers such as compound fertilizers, urea, and ammonium bicarbonate, which are too high in nitrogen content, are difficult to apply, because they are more irritating to the roots of seedlings and can be easily burned after application.
It should be noted that the fertilizer should be mixed well with the soil in the planting hole, and then the seedlings should be planted on it, and the seedlings should not be planted directly on the fertilizer. When watering the seedlings, the water should be used to fill the hole first, and then the seedlings should be planted after the water seeps. Fertilizers can also be dissolved into water, with irrigation water filling the hole, the better.
Vessel fertilization in vegetable colonization should be cautious
When the vegetables are planted, the vegetable growers like to apply a little fertilizer in the planting hole to help the seedlings quickly form strong seedlings. The fertilization method of applying a little fertilizer in the planting hole when the vegetables are planted is very good, but it must be noted that not all the fertilizer can be applied.
