The following is the northern dry farming of sugar beet film covering cultivation techniques:
Prepare before broadcast
Selecting land selection: Soils or sandy lands that are flat, deep in soil, fluffy and conducive to root growth should be selected. It is better to use corn, yams, and cereal crops as the top crop and perform four-year rotations.
Apply base fertilizer: farmland fertilizer is the mainstay, and chemical fertilizer is the principle. The yield per mu is over 3,500 kg. It should be applied to 4,000 kg of high-quality farmyard fertilizer, 50 kg of superphosphate, and 50 kg of ammonium bicarbonate. After mixing various fertilizers, One-time application in the spring.
Precision Land Preparation: The general request is to timely turn over, precision leveling, fluffy soil, virtual reality, eliminating weed roots, no waste, coupled with fertilization, to reach deep, loose, fine, flat, net, fertilizer standards. After the crop is harvested from the former crops, take a comprehensive dry-fall technique and turn it 25-30 centimeters deep in the autumn. In the winter, it will be ground in the early spring to avoid loss. Between rain and convulsions 2-3 times.
Seed settlement: Select high-quality polyploid varieties with strong stress resistance. Before 2-3 days sowing, soak the bulbs to increase the germination rate and thrifty seeds. Use 35% methylisothiphos chloride per kilogram seed before sowing. 1 kg, watered 40-50 kg, boring 24 hours, can be planted after drying, such as blight occurs seriously, can be used Fumi double 0. 25 kg or Furui Miao too, with 3 kg per 50 kg seed dressing .
Covering and sowing
Selection of plastic film: Observe the spacing of sugar beet plants using a 60-80 cm micro or linear membrane with a thickness of 0. 007mm or 0.005mm.
Coverage method: There are two methods: seeding after hole-covering and covering after filming. Normally, in the dryland, in the case of artificial coverage and single mechanical covers, the order of drilling and sowing after the first coating shall be implemented. When the film is covered, the plastic film shall be straightened and tightened tightly to the ground. The sides shall be 5-6 cm. Cover is tight, every 4-6 meters of pressure on the membrane soil, windbreak uncovered, mechanized operations to be combined with manual edge film pressing reinforcement, while adding soil. Sowing time: the beet species are shallow and less than normal, and the sowing time is usually on the April 10th to the 20th. If it is good, it should be covered with early film and promote early-onset seedlings. The difference in plague should be before and after the beginning of summer in Qingming and other natural rainfall. Immediately after sowing, sowing, or sowing, can also be covered, after the film tube nursery transfer, the effect is better, the sowing should not be deep, the depth should not exceed 3-4 cm, the same depth, each hole under the species 8-10 tablets to ensure consistent emergence.
Suitable for dense planting: Use plastic film width 60 cm, plant width and narrow ridges, plant two rows of plants, row spacing 30 cm, large row spacing 48 cm, plant spacing 27 cm, choose width 80 cm plastic film, plant 5026 cm, density should be maintained at each More than 4500 acres are suitable.
Field management
Check the seedling film: In case of strong winds, it is necessary to check in time, re-cover the mulching film that has been lifted by the wind, do a clean film, protect the film, and watch the rain after the first filming, so as to break the soil and help the seedlings. Sealed membrane holes.
Gradually seedlings: After the first sowing should be paid attention to seedlings, timely release seedlings, beet grow a pair of true leaves, the hole breaks the seedlings, the seedlings are not the top film principle. The jointed seedlings were found to lack seedlings and ridges, and were replanted in a timely manner or transplanted with paper tube seedlings for transplanting. When the two pairs of true leaves were unfolded, the seedlings were released and sealed with wet soil to prevent wind blows. At noon, the winds did not release. Seedlings, cold days, frost, temporarily delay the release of seedlings.
Dianmiao Dingmiao: When a pair of true leaves, the seedlings are released, 2-4 per hole, and 3 pairs of true leaves. Top-dressing: Dingmiao after the ridge before the middle of June before the rain plus three fat 5 kilograms, Shi Shi Shi Shen 9 cm.
Prevent pests and diseases: seedling pests, chafers occur more, should be promptly sprayed with 35% methylisoprene EC 1000 times. After entering July, 10% of sugar beets emerged with spots of brown spot. Immediately use 40% of Weiwei Wei or 50% carbendazim glue suspension, and use 75 grams of water per mu for 30-40 kg of foliar spray. Spray as appropriate.
Eliminate weeds: early weeds should eliminate field weeds.
Mid-term unmasking: After beet dressing and doubling, the role of capping and warming has been lost. In order to attract more of my rain, the film should be removed in time in mid-July. After the rain, the soil should be loosened, soil be soiled and weeded. However, care must be taken not to damage the leaves.
Timely harvest
Plastic film beet is better than the open field 10-15 days earlier harvest. Don't water for 20 days before harvest and do temporary field preservation after harvest.Fresh Broccoli,Vegetable Broccoli,Green Broccoli,Broccoli
