Second, nurture strong seedlings
1. Nutrition seedlings: Nursery soil is prepared with 70% garden soil, 30% organic fertilizer (plus 2% three-element compound fertilizer) or 80% garden soil, 20% plant ash, and 1.5% compound fertilizer. The diameter of the nutrition bowl is generally about 8 cm and the height of the bowl is 10 cm. There should be 2500 units per mu. 2, soaking germination: 30 ~ 40 °C warm water soaking 1 to 2 days (5% carbendazim 500 times liquid), and then placed in the environment at 25 ~ 30 °C germination, when the seeds can be exposed when exposed white. 3, sowing and filming: enough planting feet, sowing depth of 2 cm, and poison bait against underground pests. Double film coverage is applied to maintain moisture and promote germination and seedling growth. 4. Seedbed management: When the seedling height is 10 cm, apply a thin organic fertilizer solution to remove weeds in time, and pay attention to brown spot control, Spodoptera litura and underground pests.
Third, land preparation
1. Site preparation: Asparagus is a perennial plant and the land cannot be fully ploughed after planting. Therefore, it is necessary to plough the land before planting. General requirements of 30 to 40 cm deep, and sunburned white. At the same time, combined with site preparation of basal fertilization, per acre applied to compost soil miscellaneous fertilizer 2500 ~ 3500 kg, compound fertilizer 40 ~ 50 kg, and made a small high-ridge, ridge spacing of 1.2 ~ 1.5 meters, planting belt north-south. 2. Colonization: In general, one plant per ridge, row spacing 1.5 meters, plant spacing 0.3 to 0.35 meters, mus planting 1200 to 1500 strains. Planting density varies from place to place, some areas are spaced 1.25 to 1.5 meters, plant spacing 25 to 30 centimeters, acres planted 1500 to 2000 plants. When planting, strong and weak seedlings are required to be planted separately, and one end of the regenerated scale buds of the underground stems should be directed along the ditch in the same direction and lined up in a straight line so as to facilitate soil cultivation and bamboo shoot production.
Fourth, field management
1. Colonization: In the current year, general fertilization begins one month after fertilization. It is advisable to apply 10 to 15 kilograms of compound fertilizer per acre. In the fall, it is necessary to reapply a fall fertilizer and apply compound fertilizer 20 to 25 kilograms per acre. At the same time, pay attention to the prevention and control of pests and diseases. 2. Adult Asparagus: The management focuses on rational fertilization, disease prevention and pest control, and water drainage. 1 Rational fertilization: It can be divided into 3 to 4 times a year. Precipitating fertilizer, combined with ridge tillage and soil cultivation in March (before spring harvesting), 2000-3000 kg organic fertilizer, 51% high nitrogen compound fertilizer (30-10-11 or 25-10-16) 20～ 30 kilograms. Strong bamboo shoots fertilizer, in June (mid-middle), Mushi 51% high nitrogen compound fertilizer 10 to 15 kg. Autumn fertilizer (reapply), from August to September, Mushi soil miscellaneous fertilizer 2500 ~ 3500 kg, 54% compound fertilizer (17-19-18) 30 ~ 50 kg. 2 Disease prevention and pest management: Asparagus stem blight and brown spot disease are the main hazards that harm asparagus. The incidence is fast, and the harm is serious. At present, there is no special drug prevention and treatment.
Prevention and control of diseases should adopt comprehensive prevention and control measures, that is, timely topping and anti-lodging; clearing the pastoral area and reducing the source of infection is one of the effective methods to prevent stem blight. In February, the field cleared the stems completely, cleaned the sick leaves and branches, and burned them; Shoot stems are harvested from parent stems to extend the harvesting period; reasonable fertilization, organic and phosphorous and potassium fertilizers are added, and the amount of nitrogenous fertilizers is appropriately controlled; and carbendazim, thiophanate-methyl, mancozeb, and subtilisin can be used for chemical control. Insect pests mainly include: Drift moth disease, Spodoptera exigua, cotton bollworm, and ground tiger. Noctuids can be treated with diflubenzuron, agroforestry, etc. 1000 times, and locusts are treated with 1000 times omethoate. 3 Rows of watering: After winter clearing the garden, carry out winter irrigation. In the growing season of asparagus, run the horse water in time when drought is encountered. Never flood the area with flood water.
