Seed propagation techniques of Flos Lonicerae in spring

Pick black fruit in January. After picking and stacking with a thickness of 30cm, after ripening for 7 days after 5Mel, wash the peel and pulp in clean water and place it in a shady place to dry. Avoid exposure to the sun, then shake off the blighted seeds and store them.

Seed treatment: soak the seeds in warm water of 35 ℃ and 40 min before sowing for 24 hours, remove and mix with 3 times of wet sand, cover with plastic film and place in a warm place to accelerate germination. When the crack rate reaches 50%, the seeds can be sown.

Sowing time: spring sowing can be in early March.

Preparation of seedling bed before sowing: drought-resistant ploughing seedling bed, generally ploughing 50cm, applying sufficient base fertilizer, applying base fertilizer 6000Mel 7500kg, ammonium bicarbonate 40m 50kg, raking fine and leveling, removing residual weeds. In order to prevent underground pests, 1.5 kg of methamphetamine powder or 0.15Fl 0.25 kg of phoxim emulsion can be sprinkled every 667 square meters. Zinc sulfate or ferrous sulfate can be properly applied to prevent seedling diseases. It can be 1 meter wide, 20 centimeters high and 10 meters long and 15 meters long.

Sowing: use full box sowing, seed consumption 1.0-1.2 kg per 667 square meters. First flatten the surface of the box, water and fully irrigate, and so on after underwater infiltration, add twice as much sand to the soaked or stored sand, evenly sprinkle it into the box, cover the fine sand 0.5-0.7 cm, and then cover the grass curtain or mulch film.

Management after sowing: water management after sowing is very important, which directly affects the emergence rate. Because the seeds of honeysuckle are small, soil consolidation and cracking should be strictly prevented before the seedlings are unearthed. Should be daily inspection, cover straw curtain in the morning or evening with a spray can spray, cover the film should pick spray, that is, the lack of water block spray. When about 30% of the seedlings are unearthed, remove the mulch, and after the seedlings come out, often irrigate to keep the surface moist. Weeding, loosening soil and watering should be carried out frequently during the growing period of seedlings. Nitrogen fertilizer can be applied every 667 square meters according to the situation of the seedlings.

When the seedling height is 15 Mel 20 cm, the heart is picked and the new branches are sent out, and then 2 Mel is carried out for 3 times in succession. Each plant can have 4 Mel 8 branches in July, and can be planted out of the nursery in autumn.
