1、 What kind of fertilizer is good

Garlic needs more fertilizer and can tolerate fertilizer. Reasonable application of fertilizer is conducive to the growth in the later stage. Special fertilizer for garlic can be used to ensure that it meets the growth needs and promote the growth in the later stage. Garlic is a crop with high sulfur content. At the same time, it has more demand for sulfur. It is necessary to ensure the application of sulfur, which can improve the yield and quality. Nitrogen, phosphorus and potassium fertilizer is also needed in the growth and needs to be applied reasonably. The demand for these three elements is different in different periods. Pay attention to the application with the ratio of sulfur fertilizer. In the general preparation of fertilizer, potassium sulfate, calcium superphosphate, urea and monoammonium phosphate can be used as the main fertilizers, and some trace elements can be added to meet the demand

2、 Requirements at different stages

Garlic needs less nitrogen fertilizer in the overwintering stage, and then it will rise with growth. In the period of bulb expansion, the demand for nitrogen fertilizer is the most. At this time, it is necessary to pay attention to the application of nitrogen fertilizer. There is little demand for fertilizer before and during the overwintering period. The demand for phosphorus fertilizer increases from the beginning of returning to green to the differentiation and bolting period. The demand for potassium fertilizer is relatively large. Potassium is required in the seedling stage, which decreases in the overwintering stage and absorbs the most in the bulb expansion stage
