Asparagus is the king of vegetables. It is rich in nutrients and has a good therapeutic effect on hypertension and nephritis. It has a light taste when it tastes good. It has very good planting prospects. The following are detailed high yield and high benefits of asparagus. Planting skills, you can learn from the parents who want to grow. 1 variety selection There are many varieties of asparagus, and the asparagus varieties suitable for market sale should be selected when planting. Common asparagus varieties are Atlas, Apollo, Grandi, etc., all of which are hybrids. 2 germination Since the asparagus seed coat is thick, if it is sown without any treatment, it will inevitably lead to slow water absorption, slow germination, and uneven germination. Therefore, it is necessary to soak seeds and germination before sowing. The nursery time is determined according to the climatic characteristics. The temperate zone generally adopts the nursery seedlings. It is arranged in the middle of March to the beginning of April. The spring exposed seedlings are from the end of April to the beginning of May, and the summer and autumn exposed seedlings are generally in the upper and middle of September. 2.1 Seed disinfection and germination Soak seeds with 50% carbendazim 350~400 times for 24 h, or place the seeds in 55~57 °C hot water for disinfection. Then, the sterilized seeds are immersed in 25~30 °C warm water for 2~3 days, and the water is changed 2~3 times a day to make the seeds fully absorb water and fully prepare for germination. After soaking the seeds, the water is filtered out, the seeds are wrapped with clean and ventilated gauze, and placed at a temperature of 25~30 °C for 24 h, and 50%~70% of the seeds can be sown when exposed. 2.2 Nursery Nutritional seedlings can save more than 30% of the seed, and it is beneficial to cultivate strong seedlings and avoid damage to the roots during transplanting. The size of the nutrient meal is generally 8 cm in diameter and 10 cm in height. Each seed is planted with 1 seed, and the field requires about 37,500 pieces/hm 2 of nutrient. 3 Site preparation Asparagus is a perennial crop. It cannot be fully ploughed after planting. It requires deep ploughing before planting, 60~75 t/hm 2 of organic fertilizer and 750~1 200 kg/hm 2 of compound fertilizer. Pre-set the necessary irrigation facilities. The planting row is determined according to the field, preferably in the north-south direction. The planting row spacing is 1.0~1.2 m and the plant spacing is 25~28 cm. Generally, the planting hole is not excavated, but the planting row is ditched “plantingâ€, the groove width is 25~30. Cm, deep 30~35 cm. 4 colonization 4.1 Colonization time Protected seedlings in the Yangtze River Basin are generally planted in mid-June. Spring seeding live seedlings are generally planted in early September, allowing plants to grow for more than 2 months before entering the wintering period. Summer and autumn field nursery, can be planted before and after the next year. 4.2 Colonization method When the seedling height is 30~40 cm and the number of stems is 3~5, it can be planted. When planting, it should be planted separately according to the size of the seedlings, transplanted with soil to avoid the dryness of the fleshy roots to reduce the survival rate. When planting, the bulbs of the seedlings are 10~15 cm below the surface of the planting ditch, arranged in a straight line, and the end of the underground stalks with the buds of the scales is arranged in the same direction, so as to facilitate the cultivation and harvesting of bamboo shoots, and cover the soil 5~8 cm after planting. Slightly suppress and then pour the root water. Later, with the growth of bamboo shoots, gradually clear the ditch and fill the soil to fill the ditch. 5 Colonization management 5.1 Grass damage management After planting, the plant is short, the coverage of the branches and leaves is low, and the grass damage is very easy to occur; and if the planting is shallow, the plants are easy to fall. Management should be timely cultivating weeding, it is best to use multiple weeding to cover the weeding method of weeds, which can remove weeds and prevent asparagus plants from lodging. 5.2 Water and fertilizer management If the weather is too early, watering should be done in due course. In the flood season, it is necessary to pay attention to the timely discharge of water and sediment, and strictly prevent the accumulation of water in the field, leading to the death of asparagus roots. In the year when asparagus was planted, the key to fertilizer management was to apply more autumn fertilizer to promote the growth of asparagus. 5.3 Management after winter After entering the winter, the asparagus part of the asparagus began to wither, and the nutrients transferred to the underground roots, which is conducive to strong roots and high yields in the coming spring. At the end of winter and early spring (February), the plants on the ground should be thoroughly cleaned to reduce the source of the disease, and at the same time prevent pests and diseases. 6 Normal harvest year management 6.1 Fertilizer Management The fertilization mode with “three fertilizers†and reasonable operation is the basis for high yield and quality of asparagus. The first is germination. In March, combined with ridge ploughing and cultivating 750 kg/hm 2 of special fertilizer for asparagus, it satisfied the demand for inorganic nutrition of buds and tender stems. The second is strong bamboo shoots. In the middle of June, urea was applied at 225~300 kg/hm 2 , which was a relay fertilizer for the bamboo shoots, which was beneficial to prolong the harvesting period and increase the amount of bamboo shoots in the middle and late stages. The third is autumn fat. After the end of the bamboo shoots, combined with the fine soil flat ridges, heavy application of autumn fertilizer, generally 15~30 t/hm 2 of soil and 15 kg/hm 2 of asparagus, promote the healthy autumn shoots of asparagus, and cultivate more and stronger scales. Bud, laying the foundation for high quality and high yield in the following year. 6.2 Water Management During the harvesting of bamboo shoots, the soil in the field must be kept moist, so that the young stems grow fast, the yield is high, and the quality is good. Asparagus grows long, is more drought-tolerant and not resistant to waterlogging. During the flood season, it is necessary to pay attention to the drainage, to prevent high temperature rotten roots and the resulting diseases. 6.3 Regular weeding The cultivation management of asparagus should pay special attention to the prevention and control of grass damage, so as to avoid weeds and asparagus contending for competition and affecting ventilation. Weed control can be combined with clearing soil or cultivating weeding, and can also be used as a special herbicide for asparagus. 6.4 Management after winter After the plants in the winter are completely withered, the plants on the ground are thoroughly cleaned, the pathogens of the disease are reduced, and the number of wintering adults and eggs is reduced, so as to reduce the occurrence of diseases and insects in the coming year, which is conducive to the production management of the next year. 7 Pest Control Pest control should adopt a prevention-oriented and comprehensive prevention and control policy. Asparagus diseases mainly include stem blight and blight, and the main pests are cotton bollworm, beet armyworm, golden worm, cockroach, cockroach, thrips, and small tiger. 7.1 Disease prevention 7.1.1 Agricultural control. The dried stems on the asparagus root plate are an important source of leprosy. The key to agricultural control is to strictly eliminate diseased stems and above-ground plants, which can significantly reduce the incidence. 7.1.2 Chemical control. It can be sprayed with fungicides such as synergistic carbendazim, methyl thiophanate, chlorothalonil, mancozeb, and bacteriostatic. 7.2 Pest Control 7.2.1 Biological and physical control. Attention should be paid to the protection and utilization of natural enemies. Plant-derived pesticides such as matrine and azadirachtin can be used to control pests and diseases with biological pesticides such as Kangshensu and Bt, and insecticidal lamps can also be used to trap adult insects. 7.2.2 Chemical control. High-efficiency and low-toxic insecticides can be used to control asparagus pests, and the amount of pesticides used, the number of uses and the period of use are strictly controlled. It is forbidden to use high toxicity and high residual pesticides. 8 harvest packaging Asparagus is usually packaged very quickly after harvesting. In order to prevent decay, it should be selected after the daily dew is dried. At the time of harvesting, according to the quality requirements of the goods, the young stems of a certain length extending out of the ground are cut or cut. When the amount of shoots is reduced and thinned and weakened, or the head of the tender stems is dispersed early, harvesting must be stopped. Excessive harvesting period, shortening of green stem growth period, and reduction of assimilates accumulation will lead to a decrease in annual yield, reduced plant resistance, aging and prone to pests and diseases. Asparagus is a new type of dish that can be eaten for a long time. It has high nutritional value. In recent years, it has been favored by people because of its unique medicinal value. It is the first project of getting rich in farming, and the cultivation method is simple, only need to pay attention to fertilizer and water management. Disease prevention and control can be. Interested parents can try it out.
