Introduction of Daqinggu garlic

Daqinggu garlic is originally produced in Baiqiao garlic planting base in Shanghe, Jinan. Its green skin is purple and the variety is excellent. The yield of garlic mu is about 4000 jin per mu. Let's see how to grow it.

1. Planting time

Garlic is a crop that likes cold environment, so according to the climate and variety of each region. It can be divided into spring sowing and autumn sowing. In the northern region, the temperature in autumn and winter is relatively low, relatively cold, seedlings can not safely survive the winter, so it is not suitable for autumn sowing, through the method of raising seedlings in greenhouse, sowing in early spring and harvest in summer. In the south, the temperature is low, autumn and winter are warm enough, and the seedlings can survive the winter safely in the open air when sowing in autumn, so they are mainly sown in autumn.

2. Land preparation

Garlic is not strict on the soil, but it has a bumper harvest in the soil rich in organic matter, loose and fertile, and good drainage, so choose flat land for planting. Before planting, the land should be prepared, the soil should be ploughed deeply for 20-25cm, and then the soil should be raked fine and flat, with no obvious stones or clods. If you make a border again, the border is about 1 meter long and 4 meters wide, and you can also hit a border that is 50cm long and 4 meters wide, depending on the actual situation.

3. Sowing seeds

Select the garlic with large size and good color, use artificial peeling and breaking, remove the trays and stem plates of the garlic, grade the garlic cloves, and choose the garlic cloves with large grains, pure white appearance, no damage and no light skin as seeds. Each clove is required to weigh up to 5 grams, and the size of the seed is related to the yield, so try to choose the seed with large particles. Sowing and drying the seeds for a day or two to improve the germination rate, be careful not to choose in the high temperature period, in the temperature of 15-17 degrees, the climate is cool, the sun is not strong, if you dry the seeds when the sun is strong, the seeds may be directly dried to death. The furrow depth is 4-5cm, the row spacing is 20 × 16cm, and 1-2 seeds are sown in each ditch. After sowing, the soil is covered with a layer of thin soil after 1cm, and the soil is moistened by watering.

4. Field management

Garlic crops that need a lot of water should keep the soil in order to make them grow rapidly. generally, they should be watered four times during the whole growth period, and after one sowing, they can germinate as soon as possible; the second seedling stage can promote the rapid growth of seedlings; the third moss stage can promote the growth of garlic moss; four times in the bulb expansion period, the bulb expansion moisture should be increased to avoid poor bulb growth. At the same time, in order to achieve high yield, fertilization is also essential, the principle of fertilization is mainly machine fertilizer, a small amount of chemical fertilizer; base fertilizer, supplemented by topdressing. When planting, the mature organic fertilizer 5000kg is applied per mu, and when mixed with appropriate amount of compound fertilizer, it is evenly scattered on the ground, and the soil can be evenly mixed during deep ploughing; topdressing can be combined with watering. In addition, it is necessary to plough weeds, increase soil permeability, prevent weeds from grabbing nutrients, and strengthen the prevention and control of diseases and insect pests.
