A, asparagus planting and management
1, select the seed germination (1) choose high-quality asparagus varieties, then its seeds with 50% carbendazim 300-500 times the solution of soaking the seed for 24 hours, and then put into the temperature of 25-30 ° C temperature of warm water soaking seeds for 2-3 days, every day to change the new water 2-3 times. (2) Then use clean gauze to wrap the seeds and put them in an environment with a temperature of 25-30°C for germination, during the germination period, the seeds can usually be slightly drenched with lukewarm water at a temperature of about 25°C 1-2 times a day, and can be sown as seedlings when 80% of the seeds are white. 2, seedling (1) can choose the diameter of 10cm nutrient bowl, and then in accordance with the ratio of 2:1 to take the garden soil and organic fertilizer, and then they are crushed through the sieve, and then mixed well into a nutrient soil, and then after the completion of the film covered and placed for 7 days. (2) After 7 days, put the nutrient soil into the nutrient bowl and water it once, make a small hole in the center of the soil, then sow the seeds into the hole and fill the hole with nutrient soil. (3) during the nursery period need to maintain the temperature of the nutrient bowl in the daytime at about 25 ° C, the night to maintain 15-20 ° C, in the 20th day after the seedling as well as the 40th day after the application of urea fertilizer 1 time, but there can not be stagnant water, when the seedling age of 60-70 days, there are 3-5 stems can be planted. 3, planting (1) requires easy drainage, soil fertility and permeability are relatively good place to plant asparagus, the first mu of organic fertilizer 1-2t, 50kg of composite fertilizer, combined with deep plowing will be fertilizer turned into the soil and the plot leveling. (2) then in accordance with the row spacing of 1.5m and the north-south direction of the excavation of planting ditch, ditch depth of 30cm, before transplanting, in the planting ditch per acre strip application of 45% ternary composite fertilizer 30kg, cake fertilizer 65kg and covered with soil to maintain the depth of the ditch in the 10cm. (3) generally every 25-30cm can be planted 1 seedling, it is recommended that the strong and weak seedlings are divided into plots of planting, the strong seedling per hole with soil transplanting 1 plant per hole with soil, weak seedlings planted 2 plants per hole, followed by a small hoe soil and gently compacted, each plant to pour the appropriate amount of planting water. 4, field management (1) weeding intercropping 1 timely loosening and weeding, each time after weeding can be appropriate to cultivate the soil 1-2cm and slowly increase the height of mulch until 10cm or so, the general selection of herbicides suitable for asparagus weeding, such as diuron. 2 Because the first year of the plant is relatively small, so you can use the open space appropriate intercropping of small crops, such as soybeans, but not planting tall and absorb water and fertilizer crops, such as radish. (2) fertilizer 1 fertilizer: 7-10 days after planting, watering 1 times dilute manure water, conducive to slowing down the seedlings. 2 promote the growth of fertilizer: in the early planting of the general need for diligent fertilization, usually in each pine weeding and new stem growth before the application of 1 time, to the application of well-rotted light manure water is appropriate, when the seedlings slowly grow after the appropriate application of grass ash, burnt ash and other fertilizers with a high content of potassium. 3 Autumn Fertilizer: Autumn Fertilizer needs to be applied 1 time, usually 250-500kg / mu of organic bio-fertilizer, when the time to enter the second half of October when the end of fertilization is needed. 5, control of pests and diseases (1) diseases 1 disease types: brown spot, stem blight, anthracnose, etc. are the main diseases of asparagus. 2 prevention and control methods: in the early onset of brown spot disease using 25% carbendazim 500-800 times liquid or 80% diclofenac zinc powder 800-1000 times liquid spray prevention and control, usually also need to take the diseased plants and residues out of the field and clean up; stem blight generally available 50% pohypnol wettable powder 1,500 times liquid, 50% benomyl wettable powder 1,000 times liquid spray prevention and control; anthracnose Generally available 70% Dyson Manganese zinc wettable powder 500 times liquid spray control. (2) pests 1 types of pests: asparagus main pests are nocturnal moths, aphids, thrips, mole crickets and other types of pests. 2 control methods: night moth pests generally available 90% trichlorfon crystals 1000 times liquid or 40% of Lesbian 1000 times liquid for prevention and control; aphids and thrips generally available 25% chrysanthemum lethargy 2000 times liquid spray control, usually also need to timely clean off the weeds, to keep the field clean; mole crickets can generally be used to 3% phoxim granules 1kg mixed with 3kg of fine sand sprinkled in the seedbed for prevention and control. The company's website will be available on the web.Two, asparagus is suitable for planting in which parts of China
1, planting area Asparagus is suitable for planting in China's Jiangsu Xuzhou, Shandong Heze and other areas, of which Caoxian, Heze City, Shandong Province, is known as the "township of asparagus," because of the loose soil here, and rich in organic quality. Cao County in Heze City, Shandong Province, is called the "home of asparagus" because of its loose soil, rich in organic quality, and because it is located in the middle and lower reaches of the Yellow River in southwestern Shandong Province, where there is plenty of light and water, so it is very suitable for asparagus cultivation. 2, planting conditions (1) temperature conditions: asparagus is cold and heat-resistant, very adaptable to temperature, generally in the spring when the ground temperature rises to 5 ° C, the scale buds began to sprout, when the temperature is above 10 ° C, the shoots will begin to grow, the temperature conducive to the formation of shoots is 15-17 ° C, when the temperature is higher than 30 ° C, the growth of the plant is impeded, so that it enters into the summer dormant period. (2) water conditions: asparagus has a developed root system, relatively drought-resistant, but not flood-resistant, when there is standing water in the field will be prone to cause rotting roots, so it is required to planting plots of land to be high, and in the rainy season also need to be timely to the field of the water drained off. (3) Soil conditions: the salt content of the soil should not be higher than 0.2%, because it will lead to weak stems and leaves, and then slowly die.
