Garlic is a relatively special vegetable, and different product organs can be harvested. Generally speaking, garlic grown in the open field can harvest garlic sprouts, garlic heads and green garlic seedlings, while garlic grown in greenhouses can harvest green garlic seedlings. Mainly with garlic yellow. Among them, green garlic sprouts are a very popular vegetable. The main edible parts are the fresh leaves and pseudostems. They can be used to make scrambled eggs or make dumplings. They have a light garlic flavor.

Green garlic cultivation refers to a cultivation method that harvests the stems and leaves of garlic in the early growth stage as its products. The cycle is very short. Under suitable environmental conditions (temperature, humidity, light, etc.), garlic cloves can be harvested 60-60 days after sowing. It can be harvested in 80 days. In general, growing green garlic is not difficult. If you do these management tasks well, you can grow garlic seedlings with high yield and high quality.

1. Suitable germination conditions for garlic

The suitable temperature for garlic cloves to germinate is 18-22°C, so sowing can be done if the ground temperature is within this temperature range. The temperature in the weather forecast is generally higher than The surface ground temperature is 3-5°C higher, so you can know the approximate ground temperature by looking at the weather forecast. Temperatures vary greatly in different places. When we give technical explanations, we will talk about the suitable temperature for seed germination. We can determine the sowing time according to the local temperature conditions.

2. Choose suitable varieties for planting green garlic seedlings

To plant green garlic, choose varieties with short dormancy period, fast growth, long pseudostems, thick leaves, and fewer yellow leaves and dry tips. , such as Cangshan rough garlic, Yongnian white garlic, etc. Choose uniform, plump, and larger garlic cloves for sowing, which will facilitate the emergence of seedlings and ensure consistent emergence.

3. Sowing time

Open field green garlic seedlings are generally planted in spring and autumn; greenhouse garlic seedlings can be sown in other seasons except hot summer.

1. Autumn sowing: The specific autumn sowing time is quite different between the north and the south.

In areas south of the Yangtze River Basin: Zhejiang, Jiangsu, Jiangxi and other places, autumn garlic is usually sown from mid-August to the end of October, so that it can be put on the market before and after the Mid-Autumn Festival and National Day.

In areas north of the Yangtze River Basin: Autumn garlic seedlings are mostly sown from late July to early August and harvested from late September to early October.

2. Spring stubble:

The temperature of spring stubble garlic is relatively low when sowing, the growth is slow, and the harvest is late. The plants have 7-8 leaves and the bulbs begin. It is harvested only when it is swollen, so the growth cycle of spring garlic is very long.

Spring early garlic is sown from late April to early May and harvested from late July to early August; late garlic is sown from late May to early June and harvested in mid-to-late September.

Greenhouse planting:

In recent years, off-season green garlic seedlings have been planted in greenhouses, and the returns are quite good. The temperature in the greenhouse can be better controlled. It is best to sow seeds in early to mid-January. During the growth period, the daytime temperature is maintained at 24-28°C and the nighttime temperature is 16-20°C. The green garlic seedlings will grow quickly and neatly, and there will be few diseases. About 20 days after sowing, the first garlic seedlings can be harvested when the plant height reaches 35cm.

IV. Daily management

1. Sowing: Green garlic seedlings have a short growth cycle and are relatively easy to plant. The sowing method is the same as that of garlic. Apply sufficient base fertilizer and 4,000-5,000 kilograms of decomposed organic fertilizer per acre. After plowing the land, do sowing in flat borders, trenching, drilling or direct sowing on demand.

The sowing density of green garlic seedlings is higher than that of garlic planting. Generally, 12,000 to 15,000 plants are planted per acre, with a row spacing of 10-12cm and a plant-to-plant spacing of 3-5cm. The sowing depth is at the tip of the garlic cloves. It is advisable to cover the soil with 1-2cm after sowing and irrigate with water to moisturize.

The soil should be kept moist during the emergence of garlic. You can cover it with straw, but it is best not to cover it with mulch, otherwise the operation will be very troublesome.

2. Water and fertilizer management: During the entire growth process, frequent watering is required to keep the field moist; top dressing 2-3 times, the first top dressing after the seedlings are grown, 10 kg of urea per acre, and 10 kilograms of calcium phosphate, and topdressing again after 20 days. This time, the amount of urea can be appropriately increased to 15kg/acre. In the middle and later stages of green garlic growth, yellow leaves and dry tips are prone to appear, and foliar fertilizer needs to be sprayed 2-3 times.

As an important product organ of garlic, the planting method of green garlic seedlings is roughly as follows. Planting is relatively simple. It can also be grown as a garden vegetable in the corners of the yard or in flower pots. Even though winter is about to come, you can still plant a few pots on the indoor balcony, which not only beautifies the environment, but also is convenient for picking and eating now.
