What are the main cultivation techniques for asparagus? A detailed explanation
1. Cold-frame seedling raising The cold frame should be chosen in a spot sheltered from the wind and facing the sun, with convenient irrigation, and close to the asparagus field where it will be planted out. Generally the frame surface runs east-west, with a frame length of 10-13 m, width of 1-1.5 m, and depth of 20-25 cm. The surroundings are tamped solid, forming a frame wall 25 cm thick that is higher in the north and lower in the south. The north wall is 33 cm high, the south wall 12 cm high, and the frame walls on the east and west sides connect with the north and south frame walls. Choose agricultural film 1.5-2 m wide and straw mats 2 m wide and 6-7 m long as the cold-frame covering material. At the same time, prepare wooden poles to support the covering material. The poles are about 2 m long, with both ends placed on the north and south frame walls, one placed every 60 cm. Before sowing, apply to each frame 200 kg of sieved, fully decomposed high-quality farmyard manure, 5-10 loads of human excrement and urine, 5 kg of compound fertilizer, and 0.25 kg of carbofuran or 0.25 kg of phorate (to prevent underground pests). Sowing begins in late February: after sowing, regulate the temperature inside the frame by uncovering and covering the straw mats and agricultural film. The temperature is generally controlled at around 25°C. Seedlings begin to emerge about 20 days after sowing. When the seedlings are 15-20 cm tall, remove the straw mats and film to harden the seedlings. The seedling age is 45-50 days, and they can be planted out once there are more than 3 aboveground stems.
