In 2003-2005, it was reduced to 60,000 hectares due to SARS and natural disasters. As of January 2009, China's asparagus area only recovered. Up to 80,000 hectares, and this time the global financial crisis, China's existing asparagus area may be reduced by about 1/3. Analysis of the future prospects of asparagus. In 2009, the area of ​​asparagus in China may be reduced by 1/3 or more. With the gradual recovery of the global economy, the asparagus will enter a new golden period after 2010. After the economic recovery, the area will decrease a lot, and the price will definitely rise. It is expected that this golden period will start from 2010 and continue until 2015. After the year. Asparagus planting precautions Asparagus, also known as sarcophagus, asparagus, and glutinous rice, is a perennial plant of the family Liliaceae. The asparagus stems are green after being unearthed, and are called green asparagus. They are mainly used for fresh food. The softening of the soil is white, called white asparagus. More canned food ingredients. Asparagus contains protein, fat, calcium, iron and a variety of vitamins, is a valuable vegetable, delicious, nutritious, and high medicinal value. It can lower blood pressure, prevent and cure diseases such as cardiovascular, urinary and lymphatic diseases. It has a unique anti-cancer effect. It is a famous medicine in the world. The products sell well at home and abroad. Asparagus is easy to cultivate and easy to manage. At the same time, asparagus can be harvested continuously for 10 to 15 years, growing in the south all year round, and the northern part of the country enters a dormant state in winter. In the second year, it will continue to grow. Asparagus is adaptable and easy to cultivate. The temperature requirements are not strict. The underground part of the winter can withstand -20 °C in the soil, and the high temperature can withstand 35~37 °C in the growing season. Easy management and high output. Asparagus seeds should be soaked in warm water at 25 ° C ~ 30 ° C for 3 to 5 days before sowing. Change the water 1 or 2 times a day. Wait until the seeds are sucked out of water, mix with fine sand or vermiculite, put in a container, cover the wet towel. It is placed under the condition of 25-30 °C to germination, and it is turned twice a day. After 5-8 days of exposure, it can be sown. Asparagus seedling technology family potted plants, friends planted in small gardens, can use peat soil or nursery soil to add seedling trays, seedlings and seedling boxes to raise seedlings, covering soil thickness is about 2-3 cm. The best seedling is at a temperature of 25-30 degrees. In agricultural production, use the following method: 1. Preparation of seedbed: The seedbed should choose fertile and loose sandy loam, 2500-3000 kg of farmer's fertilizer per mu of seedbed, 20 kg of diammonium phosphate, 15 kg of potash, and ploughed into the soil after fine soil preparation. ~ 1.5 m. Seeding using longitudinal sloping lateral ditch, row spacing 20 ~ 30 cm, plant spacing 7 ~ 10 cm, with eye-catching eyes, each eye sowing a seed, covering 2.5 cm, and then covered with thin grass to warm the insulation. The sowing time is from late April to early May (the temperature is stable through 10 °C). 2, greenhouse seedlings 1 nutrient soil preparation, 30% of decomposed farmyard manure, 30% of peat, 20% of ash, 20% of farmland (no pesticide residue) 50 g of diammonium phosphate per kg of nutrient soil. 2 nutrient é’µ (8 × 12 cm) seedlings, each seed sown a seed, sowing 2 cm, covering 2 cm, watering. 3 temperature and humidity management, suitable temperature for asparagus germination 25 ° C ~ 28 ° C, 25 ° C after emergence, the highest does not exceed 30 ° C, the lowest temperature is not lower than 8 ° C, the soil is kept in a wet state is appropriate. After emergence, the seedling roots are weak, dry Watering in time, timely weeding, 7 to 10 days before planting, start large-ventilation refining, adapt to the natural environment of the outside world, to achieve the standard of healthy seedlings, there are more than 3 above ground stems, 5 to 7 underground storage roots. Asparagus colonization method Put the graded bamboo shoots into the ditch, one plant per hole of the strong seedlings, and two plants per hole of the weak seedlings. The roots are extended to the surrounding, and the buds are in the same direction in the same direction, which is arranged in a straight line, which is convenient for management of soil and harvest. Hold the seedlings, first cover a small amount of soil and compact, then cover the soil 4 to 5 cm, pour the water, cover the soil 1 to 2 cm after the water seeps, to prevent the knot and water evaporation, after transplanting 3 ~ 4 days to check the seedlings and planting in time to prevent lack of seedlings. After 15 days of management, the asparagus is irrigated and weeded, loosened the soil, ventilated and protected, and the soil moisture is maintained at 60% to 70%. The over-drying should be watered in moderation, and the rainy season should be dug and drained to prevent water from rot. Asparagus colonization in the second year and later Asparagus prevention and control 1. Stem blight [Illness] In the onset period, infiltrating brown spots appear on the main stem 30 cm from the ground, and then become pale blue to taupe, and at the same time expand into a prismatic shape, and most of the lesions are connected into strips. The edge of the lesion is reddish-brown, and the middle part of the lesion is slightly grayish brown with a small black dot on the top. If the air is dry, the edge of the lesion is clear and no longer expands into a chronic lesion. If the gas is rainy and rainy, the lesions can spread rapidly and spread, causing the upper branches to die. In the case of small branch stems and pseudo-leaves, the first faded small spots, while the back edge turns into a purple-red middle grayish white with small black spots. Due to the rapid expansion of the surrounding branches, it is easy to break or fall, and the inside of the stem is grayish and rough, so that it is dead. [conditions of the disease] The disease is caused by fungi. In the rainy and windy conditions, infection is rapid, and rainwater splashes can also be transmitted. Airborne infection is the main cause of large-scale morbidity. The direction and incidence of field spread are often affected by wind. In addition, the terrain is low, the soil is sticky, and the nitrogen fertilizer is too much, which is likely to aggravate the onset of the disease. [Control method] 1 Choose a place with high dryness and good drainage. 2 Clean the pastoral, cut off the diseased stems, pour or deep bury. 3 The field is covered with mulch film to control nitrogen fertilizer and prevent excessive growth. 4 chemical control. In the early stage of the disease, 70% methyl thiophanate 800-1000 times solution, 1:1:240 Bordeaux mixture; 50% dexamethasone 1000 times solution every 7 to 10 days, even spray 2 to 3 times. 2, brown spot disease [Illness] On the branches and leaves, there are a large number of small brownish-colored lesions; as the lesions gradually expand, the central part first turns into a light brown color, then turns into a gray color, and the later mildew layer, and has a purple brown The wheel pattern has a yellow halo on the outer edge of the lesion. Most oval lesions are enlarged to form irregular lesions. The lesions are wrapped around the stem, and the upper stems are dry. When the weather is wet, white mold can be produced, so that the leaves of the leaves will fall off early, and the growth of the plants will rapidly decline. [onset condition] The disease is caused by fungi, which is transmitted by air and is severely affected under high temperature conditions. [Control method] Same stem blight. 3, sclerotinia [Illness] The young stems are mostly in the vicinity of the ground, first faded and then brown, and then the black rat feces sclerotia. [Pathogenesis] The disease is caused by fungi. [Control method] same stem blight. 4, root rot [Illness] After the onset, the cortex of the base of the stem is rotted, and the roots are also destroyed, causing the main stem to turn yellow and the plant to decay. [Injury conditions] The disease is caused by fungi and is a disease caused by a variety of pathogenic bacteria. Mainly infected by the soil. [Control method] When the seedlings are planted, use benomyl or benomyl 400 to 500 times of the active ingredient, and soak the root for 15 minutes. 5, blight [Illness of the disease] The reddish and slightly purple lesions formed from the ground slightly above the seedling stage, so that the whole plant died. When the bamboo shoots are taken, the wounds can also be infected, and in severe cases, the whole plant will die. [Control method] The same root rot. 6, rust ã€Illness Symptoms】 Harm the stems and leaves. Orange rust spots in summer, orange powder is scattered after the skin ruptures. Dark brown lesions in autumn. The leaves will fall off early, and the whole plant will die when it is severe. [Pathogenesis] The disease is caused by fungi. The disease is prone to air humidity and poor ventilation. [Control methods] 1 Use disease-resistant varieties, such as Mary Washington. 2 Clean the countryside, do a good job of ventilation and drainage. 3 chemical control. In the early stage of the disease, 800% of chlorothalonil can be used, and 50% of sterilized Dan 800 times can be sprayed. 7. Pests Asparagus pests mainly include underground pests such as cockroaches, cockroaches, species of flies and golden worms. You can sprinkle 25% trichlorfon powder plus 5 times fine soil in the field; or mix it with 30% trichlorfon 30 times on wheat or bean cake, and withdraw it in the field to make bait; spray 80 when fertilizing % of the dichlorvos emulsion 800 times liquid and other methods to prevent and control.
