First, planting mode 1, side membrane cultivation according to the conventional planting specifications will be leveled, after laying the film, on both sides of the membrane 3-5 cm away from the edge of the membrane, artificial opening acupuncture on demand. 2. Cultivation of wide and narrow rows is 80cm wide and 40cm narrow. 3, interplanting cultivation can generally be used in time, space between the sets. Common forms include: corn, beans, corn, garlic, corn, vegetables, corn, wheat and other Chinese cabbage. 4. Planting seedlings between the plants In order to increase the seeding density of the corn, it is possible to keep the individual plants in the burrows on the basis of appropriately increasing the plant spacing. It can increase 500/667 square meters. Second, the control technology 1, the big horn spray health strong element, dwarfing hormone, dilute amines and other chemical hormones, control corn growers, reduce nutrient loss and water loss, increase production. 2, through the method of artificial castration, fertilizer regulation, hormone utilization, promote premature corn. (1) Artificial detasseling. In the early stage of corn flowering, take a ratio of 3:1, go to 3 rows of males, and leave 1 row to protect pollination, and then remove the remaining 1 row later to mature 3-5 days earlier. (2) Apply fertilizer to regulate growth period. Such methods as zinc fertilizer dressing, micro fertilizer spraying, and nitrogen control in the late can all be achieved on the basis of early emergence and early maturity of 5-7 days. (3) Hormone utilization. In the later stage of crop growth, spraying ethephon, gibberellin, etc. on the foliage can mature 3-5 days earlier. Third, the pest control technology mainly describes the control methods of spider mites: the application of chemical pesticides Nisuolang (1500 times, has a strong killing effect on eggs, larvae, no effect on adults), Krypton (2000-3000 times, when used The solution dissolves in warm water, Qishao (5000-6000 times), and 3% of 3991 granules are fumigated. IV. Prevention and control of weeds 1. Atrazine for soil treatment (Atrazine, Acetochlor, B), Alachlor (Lay), Acetochlor, etc., Sprayed before filming after sowing On the soil surface. 2. At the seedling stage, when weeds 2-3 leaves, use atrazine, 2,4-D vinegar, and yungonsi spray on weed blades to avoid contact with corn leaves. 3, some perennial weeds can choose to use herbicides, such as Roundup, Gramoxone, etc., must be directed when spraying (plus protective cover, low spray). 5. Utilization of Trace Fertilizers and Microbial Fertilizers Although there is little demand during the growth of crops, they play an important role. As long as a little bit of micro-fertilizer is added, crops can acquire more other nutrients at the same time. Corn is generally recommended to spray calcium, zinc, and magnesium fertilizers at the seedling stage. Sixth, other technology 1, different period of collection According to the different purpose of planting, choose different collection period. The best maturation period was the maturation maize. The green corn silage corn was the best from the late milking stage to the early waxing stage. The sweet and waxy corn were harvested at the top position. 2. Harvesting methods Producing corn can adopt stalk harvesting to allow sugar to continue to the grains.
 Folding Electric Wheelchair
Folding Electric Wheelchair is an important Medical Consumables for the wounded, sick and disabled at home for rehabilitation, turnaround transportation, medical treatment, and outings. The Wheelchair not only meets the needs of the physically disabled and the disabled, but more importantly, it is convenient for family members to move and take care of them. Patients, so that patients with the help of wheelchairs for physical exercise and participation in social activities.
Folding Lightweight Electric Wheelchair are generally composed of a foldable frame, front and rear wheels, left and right knee pads and footrests, left and right detachable armrests, handle brakes, seats, backrests with medical imaging data bags, bedpans, urine bag hooks, and electric standing. The hand-crank wheelchair adds a hand-crank device on the basis of the ordinary wheelchair. On the basis of ordinary wheelchairs, the electric wheelchair adds an electronic power assist system, which reduces the physical exertion of the user. Based on the electric wheelchair, the intelligent wheelchair adds positioning movement, standing movement, remote control movement and related Internet + assisted living.
