The latest course of cultivation techniques of purple-skinned garlic

Garlic is one of the seasonings often used in our daily life, and its quality can be divided into red garlic, white garlic and purple garlic according to color. Today, the pro-agricultural network wants to introduce one of them-purple garlic. From the outside, purple garlic and white garlic are only different in color, so are there any differences in planting methods? Next, the pro-agricultural network will take you to learn the cultivation techniques of purple garlic.

1. Sowing time of purple garlic

Garlic sowing at the right time, early growth and quick hair, garlic moss early bolting, high benefit. However, due to early sowing in time, the incidence of garlic leaf blight is high, and the plant is easy to senescence prematurely. The suitable sowing time is generally from late August to late September. It can be sowed early in warm and cool areas and postponed in warm areas.

2. Cultivation density

Garlic moss and garlic are mainly harvested. The general planting density is 50-60 thousand plants per mu and the sowing rate per mu is 120 kg. Sowing advocates on-demand broadcasting. According to the test results, proper deep sowing can increase the rate of garlic, so the depth of soil cover after sowing should be controlled at 4-8cm. Garlic and heavier soil cover should be shallower after rice.

III. Fertilizer and water management

Garlic root distribution is shallow, it is not resistant to drought and waterlogging, so it should be irrigated timely according to soil moisture and plant growth. Garlic has a long growing period and requires a large amount of fertilizer, generally applying 3000-4000 kg of high-quality barnyard manure per mu, especially in continuous cropping fields, but also to increase the application of organic fertilizer. The application of inorganic fertilizer, n, p, k ratio is: urea 40-60 kg, ordinary calcium superphosphate 30-50 kg, potassium sulfate 15-30 kg. Barnyard manure and calcium were used as base fertilizer at one time, urea and potassium sulfate were applied twice in mother stage (4-6 leaves) and Peng Daqi (9-10 leaves). The amount of fertilizer used in mother stage accounted for 60%, and Peng Daqi accounted for 40%.

IV. Diseases and insect pests and their control

1. Disease:

The main diseases of garlic are leaf blight, purple spot, rust, white rot, sclerotiorum and so on. Prevention and control should be based on agricultural control, supplemented by chemical control. The key of chemical control is in the early stage of the disease (after the 5-leaf stage), especially in the peak period of the disease. Chemical control agents choose 10% Shigao powder 1500 times, or 25% Shibaoke EC 1000 times, or 25% carbendazim EC 1000 times. Once in 7-10 days, 3-4 times in a row, and the control effect is more than 90%.

two。 Insect pests:

The main pests are Liriomyza huidobrensis and onion scale moth, thrips, aphids and so on. 1.8% EC can be sprayed at the 3-4 leaf stage of garlic, 10-15 ml / mu, or 1.8% Alfudin EC, or pyrethroid pesticide control, which can effectively control the harm of the insect to garlic. Grass damage can be treated with 40% garlic net 110 ml per mu or 20% chloruron 300 g / mu with water spray at 20-25 days after sowing, 3-4 leaf stage of garlic seedlings and 2-3 leaf stage of grasses. The one-time weeding effect is more than 90%, which is safe and effective for garlic production.

V. Harvest

Garlic moss harvesting: garlic moss can be harvested when the bracts of garlic moss inflorescence protrude leaf sheath 13-16cm, and choose sunny afternoon or cloudy dew to dry. Garlic: garlic generally requires "nine yellow ten harvest", too early harvest, garlic tender, heavy moisture, garlic skin wrinkled after drying, too late harvest, garlic skin discoloration easy to crack, poor commodity, product quality reduced. Garlic alone and garlic should be harvested in batches. 20-30 days after the garlic moss is harvested, the leaves can be harvested when the leaves turn yellow, and the mud, root beard and shearing handle can be removed during harvest to avoid mechanical damage.

The above is the planting technology of purple garlic brought by pro-agricultural network. We can see that the planting technology of garlic is not very different. Purple garlic and white garlic are both garlic in a fundamental sense. So what's the difference between them? We first master the planting technology of purple garlic, and then the pro-agricultural network will also make relevant introductions to their differences.
