How to grow purple garlic? High-yield cultivation techniques of Purple skin garlic

Purple garlic is famous for its garlic clove hypertrophy, juicy, spicy smell, pounded into mud and not changing taste. It is not only nutritious, delicious and delicious, but also its garlic sprouts and garlic sprouts are popular vegetables. So how should purple garlic be grown? Let's take a look at it together with Xiaobian.

1. Preparation before sowing

Garlic is a kind of crop that likes cold, needs sufficient light, likes wet and fears dry. It is advisable to choose soil rich in humus, loose and breathable, and strong in water retention and drainage. It itself can be replanted, but it is not suitable for continuous cropping with leek, scallion and other crops. Before planting, fine soil preparation should be carried out to achieve fine soil, flat ground and consistent ridge size. Garlic roots are mainly distributed in the shallow soil layer within 25 cm, wet and fertile, weak fertilizer absorption, so the quality requirements for base fertilizer are higher. The base fertilizer shall be high-quality organic fertilizer, 3000 kg organic fertilizer and appropriate amount of nitrogen, phosphorus and potassium compound fertilizer can be applied per mu, combined with watering, and the fertilizer soil shall be evenly applied into the soil in advance to avoid fertilizer damage.

2. Sowing

Garlic early sowing, high incidence of leaf blight, plants are also easy to premature senescence, so the general sowing time is late August to late September, warm and cool areas can be appropriately early sowing, warm areas can be appropriately delayed, the selection of seed garlic and seed garlic yield for seedling size, good or bad, so to choose to complete the dormancy period, seed bud full bulge, single petal in about 5g garlic clove as seed garlic. When sowing, appropriate amount of irrigation is applied on the ridge surface, and the garlic furrow should be of the same depth. When planting, the dorsal line of the mother petal should be parallel to the row direction, so that the new growth is perpendicular to the growth row direction, so that the leaves receive more light and the yield increase effect is obvious. In addition, attention should be paid to the density when sowing, and the planting density should be selected according to the garlic production density. Generally, garlic sprouts and garlic are mainly harvested, and the general cultivation density is 50,000 - 60,000 plants/mu.

3. Field management

Autumn garlic needs 7-10 days in the germination period, when there is no need for more fertilizer, seedling stage is mainly the growth of leaves, basal fertilizer can meet its needs, so no fertilizer, as long as appropriate watering can be. When the underground bulb begins to develop, fertilizer should be applied at this time, nitrogen, phosphorus and potassium fertilizer should be applied reasonably, generally 5 kg urea and 0.3 kg potassium dihydrogen phosphate should be applied per mu. In the growth period of garlic moss, the bulb begins to expand and sufficient fertilizer and water supply is needed. 0.2 kg potassium dihydrogen phosphate can be dissolved in 20kg water for many times per mu, and the effect is better. After watering and fertilizing, proper intertillage can loosen the soil, increase air permeability, preserve moisture and fertilizer, and reduce soil fertility consumption.

4. Pest control

The main diseases of purple garlic are leaf blight, purple spot, rust, white rot, sclerotium, etc. Agricultural control should be the main method, chemical control should be supplemented. Chemical control is generally in the early stage of the disease, available 10% Shigao powder 1500 times, or 25% Shibaoke EC 1000 times solution, every 7-10 days to control once, 3-4 times in succession, the effect is better. Insect pests can be controlled by spraying with low-toxicity herbicides 20-25 days after sowing.
