Planting technique of Chinese chive

Leek is the product after softening cultivation and yellowing, alias leek bud, completely in the dark environment with, so can not synthesize chlorophyll, so the leaves are yellow. So how to grow leek? Let's get to know more about it with the editor.

1. Prepare the land and make beds.

First of all, we should choose the land and quality, the adaptability of leek is strong, the requirement for soil is not high, but try not to choose heavy stubble land or spring onion and ginger stubble land to plant. Among them, the seedling bed is 1 to 1.4 meters wide, and no or less base fertilizer is applied during soil preparation. The soil is turned over to a depth of about 30 centimeters, and then flattened with a claw ditch. The planting bed should be dry and whole, and the dry border should be ditched and watered. Generally, the width of the border is 2.2 meters, the length is 30 meters and the width is about 1.4 meters.

2. Sowing and raising seedlings

The seeds should be treated before sowing, soak the seeds in warm water not exceeding 53 degrees, stir continuously until the temperature drops to normal temperature, and then mix the seeds with 2 ~ 3 ‰ carbendazim dry wet powder after soaking for 1 hour. The seedlings will be watered with low water before sowing, and then the seeds will be sown evenly. After sowing, the seeds will be flattened immediately after covering 0.5cm with sifted topsoil, spraying Hecaojing, covering the plastic film, compacting with soil on both sides, generally 2.5 kg of seeds per mu.

3. Seedling stage management

When the leek has 80% outcrop, remove the plastic film in time, when the seedlings grow to 2-3 leaves, the seedlings are watered every 5-7 days before and after growing to 5 leaves, at the same time divided into two mu with water topdressing 7.5kg urea 12.5kg, stop watering 5-7 days before transplanting.

4. Colonization

When planting, we should grasp the moderate humidity of the border, apply 10,000 jin of farm manure per mu, match 20 kg of biological fertilizer, 20 kg of urea or diammonium, 150 kg of calcium superphosphate and 35 kg of potassium sulfate, and mix the fertilizer and soil evenly. When leek grows 4-5 leaves, transplanting should be carried out according to reasonable density, and the planting depth should be appropriate. After planting, 5% phoxim granules and 25% carbendazim wettable powder should be sprinkled on the leek roots to prevent diseases and insect pests, and there is a greater demand for fertilizer and water during the growth of leek, so it is necessary to apply fertilizer reasonably according to different periods.
