In early April in early April, the seedbed is applied to the base fertilizer. The asparagus seeds are made of leather with poor water permeability and slow water absorption. They are soaked in water at 25 to 30°C for 2 to 3 days before sowing and sowed after germination. After finishing sowing the soil, cover grass moisturizing. 10 to 15 days from the start of seedlings, seedlings with 0.5 ~ 1 kg / 667 square meters, breeding seedlings can be planted in the field of 0.6 to 1 hectare.
2. Selection
Asparagus is a perennial perennial crop, generally suitable for sandy loam with fertile soil, good air permeability, deep soil layer, good drainage, and water retention and fertility; such as heavy clay with poor air permeability, shallow plowing layer, hard and strong acidity of subsoil. Alkaline soil and gravel land should not be planted with asparagus.
3. Colonization
Planted in the spring. The asparagus planting spacing is 135-150 centimeters, the row spacing is 180 centimeters, the plant spacing is 30 centimeters, the planting groove width is 40 centimeters, the ditch depth is 25-30 centimeters, the basal fertilizer and compound fertilizer are laid in the ditch, and 667 square meters of soil-fertilizer is applied. 3000-4000 kg, compound fertilizer 30 kg, cover soil 4 cm. The seedlings were planted into the trenches by plant spacing, covered with soil 3 to 5 cm, and irrigated with water until the second time after a week of easing.
4. Field management
Asparagus grows for a long period of time. In the first to second years, it is necessary to diligently cultivate, weed, and strengthen fertilizer and water, and cultivate robust plants so that they can enter the rich period as soon as possible.
1 Fertilization Asparagus requires the most nitrogen fertilizer, followed by potassium, phosphorus and calcium fertilizer. In the fall or early spring, the quality of farmyard manure is 1500-2000 kg/667 m2. When the stems are 4 to 5 cm high, sufficient water and nutrients will be given to chase the bud fertilizer urea 7-10 kg/667 m2; Fertilizer 2 to 3 times, first light and heavy, increase application of phosphorus and potassium fertilizer, with irrigation; after shooting bamboo shoots, apply organic fertilizer 1000 kg and urea 15 kg per 667 square meters, rejuvenation; August human urine; last time Top dressing finishes 2 months before frost to prevent new shoots in autumn.
2 Irrigation with timely irrigation can increase the yield and quality of asparagus. During the harvesting period, the water holding capacity of the soil is maintained at 60% to 70%. During drought, irrigation is conducted 10 to 15 days, and the frozen water is filled before the winter.
3 Pest control: Diseases include stem blight, brown spot, rust, and root rot. The main insect pests are Spodoptera litura, earthworm, golden needle, aphid, and red spider. Control methods: strengthen the clearing of the garden in the winter, prevent flooding, prevent overt clusters, etc.; chemical control can spray 1:1:300 Bordeaux mixture, carbendazim, rust sodium, agricultural resistance, etc., 7 to 10 days once, continuous 2 ~ 3 times; pest control is mainly for the trapping of adult worms, the choice of trichlorfon, chlorothalonil, deltamethrin, chlorbenazolone, rapid extinguishment and other control.

The Anti Rabies Vaccine For Human vaccine can prevent rabies. Rabies is a serious illness caused by a virus. The rabies virus is spread to humans through the bite or scratch of an infected animal. Dogs, bats, skunks, coyotes, raccoons, and foxes are examples of animals that can carry rabies. The rabies vaccine can protect you from infection if you are at high risk of exposure. The vaccine can also prevent infection after you are bitten by an infected animal.
