Detailed Explanation of Key Techniques for Garlic Cultivation for Health and Fitness

The garlic sowing season is approaching. In view of the various disease and pest damages occurring in garlic cultivation (among which the main diseases are leaf blight, gray mold, white spot disease, and purple blotch, and the main pests are root maggots, with root mites and white grubs causing relatively severe damage in some production areas), and the actual production situation of reduced garlic yield and harvest, the following comprehensive control measures are hereby proposed:

1. Select high-quality garlic seed. Sun the seed before sowing. The seed selection standards are having the characteristics of this variety, round and neat garlic bulbs, plump terminal buds, no disease spots, and no wounds. Remove garlic bulbs that are yellowed, softened, insect-damaged, have injured terminal buds, or have yellowed and rotted stem plates. Replace garlic seed retained from fields with severe disease incidence last year.

2. Soil treatment: After the previous crop is harvested, plow and sun the field as early as possible. Before sowing, broadcast Jingtuling at 5 packets per mu plus "Diyou" at 2 packets, or Fumeishi carbofuran at 3-4 jin per mu.

3. Seed treatment: Use Shishi (1 bag of pesticide per 20 jin of garlic seed) or jiailiu carbendazim (3 bags of pesticide per 100 jin of garlic seed) to treat the garlic seed. Pay attention to spraying evenly, and sow after drying.

4. Fine land preparation and sufficient basal fertilizer: Apply 2500-5000 kg of decomposed organic fertilizer per mu, or 150 jin of sulfur-containing 45% compound fertilizer (made in Japan), or 100 jin of Yupai biological organic fertilizer plus 100 jin of sulfur-containing 45% compound fertilizer (made in Japan). Avoid partial application of nitrogen fertilizer.

5. Chemical weeding: Choose Jindu'er at 100 ml per mu or Fengcaoling at 100 ml or Yacaoshuangfeng at 90 ml.

6. Reasonable crop rotation and appropriate close planting: Avoid continuous cropping with onion and garlic crops. For harvesting garlic bulbs and garlic scapes, generally use a row spacing of 16-18 and a plant spacing of 8-10, with about 40,000 plants per mu. For mainly harvesting green garlic, plant more densely. Specifically, the garlic size should be taken as the standard. Large-clove garlic seed should be planted somewhat sparsely, and medium-clove garlic seed should be planted somewhat densely. Graded sowing is required, with key management for small-clove seed.
