How to grow yellow chives? A detailed explanation of the key points of yellow chive cultivation techniques
Yellow chives are the product of garlic chives that have turned yellow after blanching cultivation, also known as chive sprouts. They grow entirely in a dark environment, so they cannot synthesize chlorophyll, and therefore the leaves are yellow. So how should yellow chives be grown? Let's learn about it together with the editor.
1. Land preparation and bed making
First, choose the land and quality. Garlic chives have strong adaptability and do not demand much from the soil, but try not to choose continuous cropping land or land previously planted with scallions or ginger. The seedling bed is 1-1.4 m wide; during land preparation, apply no base fertilizer or only a small amount, turn the soil about 30 cm deep, after turning use a claw hoe to level it, then tread it flat. The planting bed should be prepared on dry land, with furrows opened in the dry bed and then watered. Generally the bed is 2.2 m wide, 30 m long, with a bed width of about 1.4 m.
2. Sowing and seedling raising
Before sowing, first treat the seeds by soaking them in warm water not exceeding 53°C, stirring constantly while soaking until the temperature drops to room temperature, then stop. After soaking for 1 hour, mix the seeds with 2-3‰ carbendazim wettable powder and set aside for use. Before sowing, water the seedling bed thoroughly, then sow the seeds evenly. After sowing, cover with sieved topsoil 0.5-1 cm deep, then immediately level it, spray with herbicides such as Hecaojing, cover with plastic film, and press the sides firmly with soil. Generally 2.5 kg of seed is used per mu.
3. Seedling stage management
When 80% of the yellow chives have emerged, remove the plastic film in time. When the seedlings grow to 2-3 leaves, thin them once. Around the 5-leaf stage, water once every 5-7 days, and at the same time apply urea as a topdressing with the water in two applications at 7.5-12.5 kg per mu. Stop watering 5-7 days before transplanting.
4. Planting
When planting, ensure the soil moisture of the bed is moderate. Apply 10,000 jin of farmyard manure per mu, together with 20 kg of biological fertilizer, 20 kg of urea or diammonium phosphate, 150 kg of superphosphate, and 35 kg of potassium sulfate, and mix the fertilizer and soil thoroughly. When the yellow chives have grown 4-5 leaves, they can be transplanted. Transplant according to a reasonable density, and the planting depth should be appropriate. After planting, along the rows sprinkle 5% phoxim granules and 25% carbendazim wettable powder on the chive roots to prevent pests and diseases. Yellow chives have a relatively large demand for fertilizer and water during growth, so fertilize reasonably according to different periods.
