Planting method and time of green garlic (explain the correct planting method of garlic seedlings in detail)

Garlic is a special vegetable, which can harvest different organs. Generally speaking, garlic planted in the open field can harvest garlic bolts, garlic heads and garlic sprouts, while garlic planted in greenhouse mainly harvests garlic sprouts and garlic yellow. Among them, green garlic seedling is a very popular vegetable. Its main edible parts are tender leaves and pseudostems. Scrambled eggs, jiaozi, and a touch of garlic.

Green garlic planting refers to the cultivation method of harvesting the stems and leaves of garlic at the early stage of its growth, which has a short cycle. Under suitable environmental conditions (temperature, humidity, light, etc.). ), garlic cloves can be harvested 60-80 days after sowing. Generally speaking, it is not difficult to grow green garlic. Only by doing these management work well can we produce high-yield and high-quality garlic seedlings.

First, the suitable germination conditions of garlic

The suitable germination temperature of garlic cloves is 18-22℃, so the ground temperature can be planted in this temperature range. The temperature in the weather forecast is generally 3-5℃ higher than the surface temperature. You can know the approximate surface temperature by watching the weather forecast. The temperature varies greatly in different places. When we give technical explanations, we always talk about the suitable temperature for seed germination. We can decide the sowing time according to the local temperature.

Second, choose varieties suitable for planting green garlic seedlings.

Green garlic should be planted with varieties with short dormancy period, fast growth, long fake stems, thick leaves, few yellow leaves and few dry tips, such as Cangshan coarse garlic and Yongnian white garlic. Sowing should choose garlic cloves with uniform size, fullness and large size, which is beneficial to the emergence of seedlings.

Third, sowing time.

Green garlic seedlings in the open field are generally planted in spring and autumn; Garlic seedlings in greenhouse can be sown in other seasons except hot summer.

1, autumn stubble: the specific autumn sowing time is quite different between north and south.

In areas south of the Yangtze River Basin: Zhejiang, Jiangsu, Jiangxi and other places, garlic, an autumn crop, is generally sown one after another from mid-August to the end of 10, so as to be listed around the Mid-Autumn Festival and National Day.

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 June.

2. Spring stubble:

In spring, the sowing temperature of garlic is relatively low, the growth is slow and the harvest is late. The plant has 7-8 leaves, and it is harvested only when the bulbs begin to swell, so the growth cycle of garlic in spring is very long.

Early-maturing garlic in spring is sown in late April to early May and harvested in late July to early August. Sow late garlic from late May to early June, and harvest it in the middle and late September.

Greenhouse planting:

In recent years, there have been more anti-season green garlic seedlings planted in greenhouses, and the income is quite good. The greenhouse can better control the temperature, sowing more than 65438+ in the middle of 10, keeping the temperature at 24-28℃ during the growing period and 16-20℃ at night, so that the green garlic seedlings can grow rapidly and orderly with few diseases. About 20 days after sowing, when the plant height reaches 35 cm, the first garlic seedling can be harvested.

Fourth, daily management.

1. Sowing: The growth cycle of green garlic seedlings is short, which is better. The sowing method is the same as planting garlic. Apply base fertilizer, and apply 4000-5000 kilograms of decomposed organic fertilizer per mu. After turning over the soil, do flat bed sowing, furrow sowing or direct sowing.

The sowing density of green garlic seedlings is higher than that of garlic planting. Generally, 12000 ~ 15000 plants are planted per mu, the row spacing is 10- 12cm, the plant spacing is 3-5cm, and the sowing depth is appropriate to slightly expose the tip of garlic cloves. After sowing, cover the soil with 1-2cm, and water and moisten it.

Keep the soil moist during the emergence of garlic. It can be covered with straw, but it is best not to cover it with plastic film, otherwise the operation will be very troublesome.

2. Water and fertilizer management: During the whole growth process, it is necessary to water frequently to keep the field moist; Topdressing 2-3 times, topdressing for the first time after full seedling, topdressing urea 10 kg per mu, calcium superphosphate 10 kg, topdressing again after 20 days, this topdressing can appropriately increase the application amount of urea, which is 15 kg/mu. Yellow leaves and dry shoots are easy to appear in the middle and late growth period of green garlic, so foliar fertilizer should be sprayed 2-3 times.

As an important organ of garlic, the planting method of green garlic seedlings is probably like this, which is relatively simple. It can also be planted as a garden vegetable in the corner of the yard or in a flowerpot. Even if it is winter, you can plant a few pots on the indoor balcony, which not only beautifies the environment, but also facilitates picking and eating now.
