How to grow spring-planted garlic for high yields? Master these four cultivation points
Garlic planted in spring and harvested in summer has a shorter seedling stage and less nutrient accumulation, so both yield and quality are inferior to autumn-planted garlic. To improve the yield and quality of spring-planted garlic, you must select good varieties and focus on management. The key is to do well in the following four aspects:
1. Choose suitable varieties: spring-planted garlic takes about 100 days from planting to harvest, and the whole growth period is very short, so choose short-growing-period purple-skin garlic as seed garlic.
2. Apply heavy base fertilizer: before sowing, while preparing the land, apply 3000 kg of high-quality human and livestock manure or barnyard manure per mu, 50 kg of 15:15:15 nitrogen-phosphorus-potassium compound fertilizer, rake level and harrow fine, mix the fertilizer and soil thoroughly, and prepare the seedbed for sowing.
3. Sow early at the right time: sow spring garlic as early as possible within the suitable period to extend the growth period. As the farming proverb says, "Plant garlic before the ninth, or you'll grow single-clove garlic after the ninth." Garlic is cold-tolerant, and early sowing will not suffer freezing injury. Late sowing easily forms low-yielding single-clove garlic. Therefore, you should prepare the land early and sow on frozen soil. The plant spacing is 8 cm x 15 cm.
4. Strengthen seedling-stage management: spring-planted garlic has a short seedling growth time, so on the basis of applying sufficient base fertilizer, appropriate topdressing and watering should be done. After May, the temperature gradually rises, and timely watering is a key field management measure. During the seedling stage, water lightly with a small amount of water and cultivate to conserve soil moisture to increase soil temperature. When the garlic seedlings have 2 leaves, carry out one cultivation; at the 6-leaf stage, water for the first time, then water once every 5-7 days. During cultivation when the seedlings are fully emerged, combine with watering and apply 75 kg of cake fertilizer or 20 kg of ammonium bicarbonate per mu as topdressing, while strengthening integrated control of diseases, insect pests, and weeds.
