High-yield Planting And Cultivation Technology Of Garlic

1 Land preparation and fertilization

1, first of all, to intensive cultivation, formula fertilization.

2, the base of base fertilizer, topdressing.

3. In the process of garlic growth, it is more sensitive to the use of microbial fertilizer, medium and trace elements, and organic matter fertilizer. If the organic matter is lacking, it is easy to appear quality decline, physiological diseases, and affect the yield.

4. In the past two years, in the actual use of fertilizer, the performance of controlled release fertilizer in garlic is particularly obvious. The most obvious effect is the controlled release fertilizer of polyamide ester, followed by sulfur coating, urea formaldehyde and resin coated fertilizer, the effect of controlled release for a long time, can ensure that garlic does not take off fertilizer after spring.

5. The demand rule of garlic for chemical fertilizer: the demand for nitrogen, phosphorus and potassium fertilizer is 1.4:0.4:1. (Although garlic is fond of nitrogen fertilizer, it can not be applied at one time. Excessive early application will burn seeds, resulting in uneven emergence or broken ridges. Phosphorus fertilizer is recommended to do base fertilizer use, should not be too much, too much will affect the normal growth of the seedling stage, plant short, slow growth and other symptoms. Potash fertilizer can mostly do base fertilizer, less half do topdressing use. Specific can use polyamide ester nitrogen and phosphorus potassium controlled release fertilizer, 100 kg per mu, after spreading the ground to do bottom fertilizer. Garlic is also a sulfur-loving crop, more sensitive to sulfur elements, sulfur deficiency leaves are prone to bad spots, leaf curl, the normal use of potassium sulfate fertilizer can be supplemented).
