3, set the "solar wind" wind barrier to promote growth "Solar" wind barrier is a kind of wind barrier made with reflective screen, with the advantages of improved light, increase the temperature, can significantly increase production, promote the early listing of leek. Construction method: Prepare a two-meter-wide reflective film, the length of which can be determined according to the length of the leeks, and bury a stake every 3-5 meters on the northern edge of the leeks, mainly to fix the effect, and the stakes. To tilt forward 60 degrees, this is conducive to the reflection of the sun on the reflective screen to the surface of the skull, and then in the east and west direction between the stakes and stakes to pull a number of parallel steel wire, wire and wire spacing of 10 cm, in the steel wire The north side of the curtain hanging reflective screen, and then inside and outside with a small bamboo crucible clamp tightly, so that it is fixed on the wire mesh, pay attention to clamping the fixed light curtain spacing is about 30 cm.
How to improve the yield and quality of leeks
1. If you want to achieve high yields, you must prevent diseases first. Among them, the prevention of lodging of leeks is an important measure to prevent the occurrence of leeks. Take the scaffolding method, that is, to lay 30 centimeters high rafts at a distance of 20 centimeters between the two ends of the leek, and to add iron wire between the rafts, and then add two iron wires every 5 meters. The hibiscus is fixed. Between each ridge of leeks, fine bamboo is placed on the wire in a north-south direction, with a spacing of 20 cm. The lashing is good. The leaves can grow on the wire and bamboo poles without lodging.
