When do you plant chives?

Leek belongs to the perennial root vegetable of Liliaceae, and it is a kind of vegetable that everyone likes very much. It has the functions of tonifying the liver and stomach, tonifying the kidney and warming yang, moistening the intestines and relieving defecation. In recent years, with the development of agriculture, the planting area of leek is also increasing. So, when will the leek be planted? Now the planting time and method of leek are introduced as follows.

1. Planting time of leek

1. Spring sowing: it is better to sow early than late, and the local temperature is stable at 5-10 ℃ in spring, when the land is not fully melted, and the return to the surface is moist, so it is easy to emerge seedlings. This sowing method also avoids grass damage, because leek seedlings come out quickly after sowing, and the temperature at that time is not suitable for weed germination, resulting in jet lag. Therefore, it is recommended that people try to use this kind of sowing method.

two。 Summer sowing: generally sowing after the strike of cucumbers and tomatoes, at this time the high temperature is prone to drought and waterlogging, the sowing amount is about 1/3 larger than that in spring, and the soil cover is not easy to be too thick, keeping the soil moist, which is conducive to the emergence of the whole seedling.

3. Autumn sowing: generally sowing before and after the Beginning of Autumn, the sowing amount is twice as large as that in spring, and the management is mainly dry and wet. Attention should be paid to grass damage in the later stage. Autumn sowing is generally not recommended.

Second, the planting method of leek

1. Leek seedlings: select varieties with full seeds, no impurities, no insect population, cold resistance, disease and insect resistance, heat resistance, strong tillering ability, good appearance and internal quality. The amount of seed used in the seedling field is 5-6 kg per mu, and it can be transplanted to 6-7 mu in the field. Seed treatment. Dry seed direct seeding (mainly spring sowing) can be used. Most of the seeds in Guangzhou are sown from October to December and transplant from March to April. The seeds can also be soaked in 40 ℃ warm water for 12 hours to remove blighted seeds and impurities, wash the mucus on the seeds and accelerate germination. The soaked seeds are wrapped in a wet cloth and germinated under the condition of 16-20 ℃. Rinse with clean water 1-2 times a day. More than 60% of the seeds can be sown when they are white. Prepare the soil and fertilize. The seedbed should choose high dry land that can be irrigated and waterlogged, sandy soil should be selected, deep ploughing should be carried out before sowing, shallow ploughing, fine raking, and combined with fertilization should be carried out near sowing, and the border should be leveled to make a border with a height of 12-14 cm and a width of 100-120 cm.

two。 Leek sowing: tread the ditch (border) once, step on it, water it along the ditch (border), soak the germinated seeds with 2-3 times as much sand in the furrow, cover with fine soil, cover with film or straw after sowing, and remove the bed cover when 70% of the seedlings are unearthed. Water and fertilizer management after sowing. Watering every 2-3 days before emergence is needed to keep the soil surface moist, from full seedling to seedling height 16 cm, watering once every 7 days, combined with watering, 3 kg of nitrogen fertilizer for each, drainage and waterlogging prevention in high wet season. After the Beginning of Autumn, the combination of watering and topdressing twice, each mu of nitrogen fertilizer 4 kg, generally not harvested before planting, in order to promote strong seedlings and roots. When the weather turns cold, you should stop watering. In addition, weeds should be weeded in time.

3. Planting of leek: the seedling stage is 120 days, the seedlings have 7-9 leaves, and the planting period is when the plant height is 18-20 cm. The season of high temperature and humidity should be staggered when planting. The main planting methods are: single plant close planting, small clump close planting, small ridge cluster planting, wide ridge and large pinch and so on. The leek seedlings will be raised, cut off the fibrous root apex, leaving 2-3 cm to promote the development of new roots, and then cut off a section of leaves to reduce foliar evaporation and maintain the balance of root absorption and foliar evaporation. The row spacing was 10 × 20CM, 10 seedlings were planted in each hole, or 36 × 20CM were planted in each hole, and 20-30 plants were planted in each hole. The suitable planting depth was not to bury the tiller node.

4. Water and fertilizer management: watering twice in 3 days after planting, hoing and squatting seedlings 2-3 times in time, the soil is semi-dry and wet, and waterlogging should be drained in time when entering the rainy season. The fertilizer tolerance of leek is very strong. Before planting, the soil preparation (2 meters Baokeng) is deeply ploughed and treated with rotten basic fertilizer, 2000 kg per mu. The principle of fertilization is the combined use of organic fertilizer and inorganic fertilizer, the proportion is not less than 1:1. Fertilization should be based on the growth situation, weather, soil dryness and humidity, and the principle of light application should be adopted: seedling height less than 35 cm, compound fertilizer and water 500 kg per mu, seedling height more than 35 cm, 800 kg of rotten manure per mu, and 5 kg compound fertilizer at the same time, the dilution multiple should be increased in dry weather. A small amount of leek flowers can be harvested 45 days after planting, focusing on "raising roots and strong seedlings", and it is suitable for harvest in the early morning. Mixed sowing of coriander or other leafy vegetables at the initial stage of planting can cool down and increase income.

[editor's conclusion] the taste of leek is very delicious and has a unique flavor, so it is favored by consumers and has high planting value. Above for you to introduce the planting time and methods of leek, I hope to be able to help you!
