First, check seedlings, make up seedlings After the emergence of corn, check seedlings and fill seedlings should be carried out immediately. Before the three-leaf stage of maize, it was found that more than 3 strains (acupoints) were continuously seedling-repaired, and seedlings should be promptly filled. The method of transplanting seedlings with soil could be adopted to reduce the difference in seedling potential between the plants. Transplanting should be carried out on rainy days or in sunny afternoons. Watering should be carried out in time after planting to shorten the time for seedlings to ensure survival. Seedlings below 3 (points), in the lack of seedlings on one or both sides, you can leave two plants, corn seedlings generally do not advocate reseeding. Second, the seedlings, Dingmiao Appropriate time seedlings and seedlings are the key to reduce the rate of weak plants, improve the uniformity of the population and ensure the appropriate density. Corn grows fast and should be planted in a timely manner. Generally grasp 1-2 tablets of time for spreading seedlings, and 2-3 tablets for spreading seedlings. The principle of thinning seedlings is to leave weak seedlings to keep strong seedlings and to leave diseased seedlings to keep healthy seedlings. The time of thinning and setting seedlings should be carried out in the sunny afternoon, because diseased seedlings, insect bite seedlings and poorly growing seedlings are easy to wilt at this time, which is easy to identify and eliminate. For the seedlings with dense leaf, thick and thin, and distorted silk black spikes, they should be completely removed. Third, pest control Summer corn seedlings are weak and susceptible to pests and diseases. Light causes slow growth, dead seedlings, diseased seedlings, lack of seedlings and ridges, and heavy seed damage. Summer corn seedlings susceptible to ground pests are corn borers, cotton bollworms, armyworms, thrips, aphids, swat flies, etc., vulnerable to underground pests such as ploughing, sunflower worms, earthworms, tigers, etc., vulnerable to The main pest in the surface of Hebei province is the two-pointed armyworm. The seedlings should be observed at any time. In the early stage of insect pest damage, appropriate insecticides should be selected to fight drugs in time.

Manual medical beds can be divided into double-shake medical beds and single-shake medical beds. Medical beds, flat medical beds.
According to whether it can be moved, it can be divided into a wheeled medical bed and a right-angle medical bed. Among them, electric medical beds are generally movable with wheels.
In addition, there are other special function beds, such as: ultra-low three-function electric bed, Hospital Bed For Home, hospital bed with bedpan, scald rollover bed, rescue bed, mother-child bed, crib, child bed, ICU monitoring bed, examination bed, etc.
