(1) Prepare the land
In order to obtain high quality and high yield, it is appropriate to choose soil rich in organic matter. Usually 1000 kg of organic fertilizer should be applied as base fertilizer per mu, and made into a 1.5-meter-wide high border to be sown.
(2) Live broadcast
Due to the small size of the seeds, it is advisable to mix the seeds with fine sand and sow them when sowing to ensure uniform sowing. The soil mass should not be too large, so as not to affect the emergence. Cover the sunshade net after sowing and remove it after emergence. Sowing can be carried out from February to November, but it is suitable from March to May.
(3) Field management
Pay attention to watering to keep the soil moist. More than 20 days after planting, when the plant height is 15-20 cm, the harvest will begin one after another. It is better to harvest the plants without inflorescence. Each stubble is 30-40 days, and the yield per mu is about 1000 kg.
(4) Seed retention
In September-October, pick a field that grows vigorously, do not harvest and let the flowers bloom and produce seeds.

Many improper technical actions in sports are easy to cause knee joint injury. The fitting function of knee pad makes the knee joint stable during the movement, and wraps the lower end of quadriceps femoris, limiting the knee joint over-extension; The opening knee pad has a stronger restrictive effect, which greatly reduces the range of knee flexion and extension. Its good compression effect can effectively disperse the pressure on the knee and reduce the risk of sports injury.
Knee pads have a certain thickness and elasticity, which can buffer the impact force when colliding with hard objects during movement, and protect the knee joint.
Especially when exercising in cold weather, the lack of muscle contraction on the knee produces heat and is easy to catch cold. Knee joint cooling is related to many diseases including arthritis. Knee pads can effectively keep warm and prevent the knee joint from getting cold.
