How to grow the latest purple-skin garlic? High-yield cultivation techniques and method tutorial for purple-skin garlic
Purple-skin garlic is renowned for its plump cloves, abundant juice, and strong pungent flavor, and for the fact that it does not lose its taste when pounded into a paste and left to stand. It is not only nutritious and delicious, but its garlic sprouts and garlic scapes are also vegetables that people love. So how should purple-skin garlic be grown? Follow along with the editor to take a look.
1. Pre-planting preparation
Garlic is a crop that prefers cool conditions, needs ample sunlight, and likes moisture while fearing dryness. For planting, it is best to choose soil rich in humus, loose and airy, with strong water retention and drainage. It can itself be grown in continuous cropping, but it should not be planted in succession with crops such as Chinese chives and Welsh onion. Before planting, the soil must be finely prepared, ensuring the soil is crumbly, the ground is level, and the beds are uniform in size. The root system of garlic is mainly distributed in the shallow soil layer within 25 cm, and it likes moisture and can tolerate fertilizer, with relatively weak fertilizer uptake, so the quality requirements for base fertilizer are relatively high. For the base fertilizer, choose high-quality organic fertilizer; 3000 kg of organic fertilizer per mu and an appropriate amount of nitrogen-phosphorus-potassium compound fertilizer can be applied, applied together with watering. The fertilizer and soil should be evenly incorporated into the soil in advance to avoid fertilizer burn.
2. Sowing
When garlic is sown early, the incidence of leaf blight is high, and the plants are also very prone to early senescence, so the general sowing time is from late August to late September. In cool regions, sowing can be appropriately earlier, and in warm regions it can be appropriately delayed. The selection of seed garlic and the yield of seed garlic have a relatively large effect on the size and quality of the seedlings, so choose garlic cloves that have completed dormancy, whose seed-clove buds are plump and protruding, and whose single cloves weigh about 5 g as seed garlic. When sowing, irrigate the bed surface appropriately, then open furrows and sow by dibbling. The garlic furrows should be uniform in depth. When planting, make the line connecting the back and belly of the mother clove parallel to the row direction, so that the new growth comes out exactly perpendicular to the row direction, allowing the leaves to receive more sunlight, with an obvious yield-increasing effect. In addition, pay attention to density when sowing, and choose planting density according to garlic production density. Generally, when the main purpose is harvesting garlic scapes and garlic bulbs, the usual cultivation density is 50,000-60,000 plants/mu.
3. Field management
Autumn-sown garlic takes 7-10 days in the germination stage, during which it does not need much fertilizer or water. In the seedling stage, it mainly grows leaves, and the base fertilizer can meet its needs, so no fertilization is needed, only appropriate watering. When the underground bulb begins to develop, fertilization is then required, with nitrogen, phosphorus, and potassium fertilizers applied reasonably. Generally, 5 kg of urea and 0.3 kg of potassium dihydrogen phosphate are applied per mu. During the garlic scape growth period, the bulb begins to expand and needs a sufficient supply of fertilizer and water. For better results, 0.2 kg of potassium dihydrogen phosphate dissolved in 20 kg of water can be sprayed multiple times per mu. After watering and fertilizing, appropriate intertillage and loosening of the soil can loosen the soil, increase air permeability, preserve soil moisture and fertilizer, and reduce soil fertility consumption.
4. Pest and disease control
The main diseases of purple-skin garlic include leaf blight, purple blotch, rust, white rot, and sclerotinia rot. Control should be based mainly on agricultural control, with chemical control as a supplement. Chemical control is generally carried out in the early stage of disease onset. A 1500-fold dilution of 10% difenoconazole powder, or a 1000-fold solution of 25% prochloraz emulsifiable concentrate, can be used, applied once every 7-10 days for 3-4 consecutive times, with relatively good results. For insect pests, 20-25 days after sowing, low-toxicity herbicides can be sprayed for control.
