Asparagus Spring Management Technology

First, the use of fertilizer to sterilize soil in the field of bamboo shoots, and 16% of antibacterial nets for 15 mu (2 sachets) of water for 30 kilograms after the garden is used, and the surface of the asparagus is sprayed with ground sterilizing, and 1 kilogram of underground bio-pesticides are added with “green generals”. Spread 10-15 kilograms of pesticide to kill and then soil. When cultivating soil, all the ridge surface pesticides and fungicides shall be covered, and the depth of cultivating shall be 12-15 cm from the top of the stalk to the stem plate. Each mus can add 3-5 parts of decomposed organic fertilizer, or 2-3 pieces of broiled chicken manure, dedicate 25 kg of asparagus fertilizer and 2 kg of biological potassium, then fully mix the soil to a depth of 10-12 cm. While watering. However, it should be noted that the manure must be finely crushed and mixed, and the mixed soil should not be too deep to prevent the burning of roots and roots.

Second, planting management before July 20, 2007 nursery to be planted on February 15-25, after July 20 seedlings can be planted in early May. Planting by ditching, ditch depth 30-40 cm, width 40-50 cm, Mushi rot 3-5 m, chicken dung 2-3 m, compound fertilizer 25 kg, biological potassium 2 kg, after The "Green General" bio-insecticide is applied with 1 kg of soil and 10-15 kg of soil. Finally, the soil, fertilizer, and medicine in the trench are evenly mixed and the bottom of the trench is leveled. After the completion, the bottom of the ditch is preferably 10-12 cm lower than the original ground. Before the planting, 16% of fungicides were used to kill 2 bags of soil and 30 kg of water was sprayed on the soil. The early high-yield type of planting with a row spacing of 1.3 meters and a spacing of 25 centimeters was used, with about 2000 strains per acre. Attention should be paid to orientation when planting, that is, digging 3-5 cm deep pits at the bottom of the trenches and then covering the soil. Watering in time after planting, water infiltration after the cultivation of soil 1-2 cm soil protection, pay attention to the timely inspection of seedlings, make up seedlings, after spraying to prevent disease after the rain. Seedlings grow to 30 cm high when earth 3-5 cm, in mid-May chase asparagus special fertilizer 15-25 kg.

Third, spring harvesting will be planted before the end of June 2007. After the fall, the plant height will be between 1 m and 1.5 m, and 7-10 rhizomes. Spring harvesting can be continued until May 10-20; stems will be planted from May 10-20, and will be planted after July 2007. Plants with a height of 1 meter and a stem number of 5 roots were released from April 25 to May 5. The planting of plants before 2006 depends on the growth of asparagus and the condition of the disease. The growth is good and the disease is light until June 20. The growth is weak and the disease can be recovered until May 20th.
