What fertilizer does garlic need?

1. Basic principles of fertilization: Scientific and reasonable fertilization should be made according to the fertility level of soil and the needs of garlic in different fertility periods. The principle of "light in the front, heavy in the middle, and then supplemental" fertilization should be grasped, so as to prevent over-exuberant and crazy growth in the early stage and avoid premature decay in the late stage.

2. Fertilization of the whole land: Garlic plots need to be deeply plowed and harrowed to enhance the permeability of the soil, which is conducive to the activities of soil microorganisms and the transformation of soil nutrients, and to improve the capacity of the soil reservoir, which is conducive to the development of the root system and bulb expansion. To be in the previous crop after the harvest early plowing and tillage, plowing depth of 20-25 centimeters.

Therefore, before sowing, you should apply sufficient fertilizer at one time combined with land preparation, including 2,500-3,000 kg of farmyard manure, 40-75 kg of chloride-based compound fertilizer, 1.5-2 kg of ferrous sulfate, manganese sulfate, borax, zinc sulfate and copper sulfate per mu, and sprinkle it on the fa.

3. Application of plucking fertilizer: Garlic is different from other crops, when the climate is normal, for garlic in the greening period, field management is usually not carried out to avoid the big occurrence of sexual soft rot caused by the sudden drop of ground temperature due to premature watering, so that the growth of garlic is affected; therefore, the second chasing fertilizer should be put in the plucking period, and 20-25 kg of nitro compound fertilizer can be chased in mu. The second fertilizer should be applied at an interval of 15-20 days, and the amount should be about 20 kg.

When garlic enters differentiation and moss extraction stage, nutritional growth and reproductive growth are carried out at the same time, and the demand for phosphorus is strong, which is also a key fertilizer in the life of garlic.

5. Extra-root fertilizer: Medium and micro elements such as calcium, magnesium, iron, manganese, zinc and copper are necessary for the growth and development of garlic, which can be supplemented by foliar spraying, or combined with pest control, but pay attention to the nature of medicine and fertilizer. Fertilizer spraying time: It should be done before 11:00 a.m. or after 4:00 p.m. on a sunny day. The type of fertilizer to be sprayed: Use 2 kg of calcium or 1 kg of sulfur-based compound fertilizer soaked in 50 kg of water for 12 hours and take its clarified solution to spray 1 mu; also use 0.2%-0.4% solution of potassium dihydrogen phosphate and 0.15% solution of manganese sulfate, 0.5% borax, 0.2% zinc sulfate and 0.15% copper sulfate. In the middle and late stages of garlic growth, 1-2 foliar sprays can be carried out at 7-10 days intervals according to the growth and phase.
