1. Deep fertilization 50 to 100 kg of slag per 667 square meters, 40 kg of nitrogen, 28 kg of phosphorus, and 8 kg of potassium sulfate as base fertilizer.
2. Seed treatment Selected seeds were treated with sulfuric acid and their quality reached the national standard. Add 100 kg of cotton seed, add 0.8 kg of 60% of 3911 water, and add 3 kg of seed dressing, dry it, and then apply it at a ratio of 1:50 in the seawater 818 special agent plus Fortune A coating agent. The treated seeds are left to dry. broadcast.
Second, sowing before sowing chemical weeding, fine soil preparation, can be sown when the temperature of 5 centimeters stably through 10 degrees Celsius, the northern part of the suitable sowing period is the end of April to April 20, the sowing method is 25+50+25 centimeters away from the membrane. The film spacing is 60 cm, the spacing between the plants is 10 cm, and 1 film and 4 rows are used for drip irrigation. The drip irrigation tube is laid with 1 film and 2 tubes.
3. Before cultivating sowing, the irrigated cotton field immediately after sowing should be cultivated once, and cultivated for 2 to 3 times to ensure the quality of cultivator, increase the temperature of the soil, and artificially assist the liberation of cotton seedlings in a timely manner to reach one seedling, seedlings and seedlings. In a true leaf when the Dingmiao, two true leaves will be completed seedlings, to stay weak. 1 cave 1 plant, 667 square meters Baomiao 16000 ~ 17000 strains.
IV. Top-dressing conventional irrigation plots, from the bud stage to the early flowering stage, the first ditch is topdressed before the first water, 667 square meters is applied with 30 kg of standard nitrogen and 10 kg of standard phosphorus, and the flower and boll stage is top-dressed before the second water, 667 square meters. Apply 20 kg of standard nitrogen to meet the needs of buds, flowers and bolls. The drip-irrigated plots were dripping with chemical fertilizers. The first flowering to early flowering period (mid-to-late June) dropped 6 kg of standard nitrogen and 2 kg of phosphorus; the second flowering stage reached the flowering stage (early July) and dropped 10 kg. The standard nitrogen plus 3 kg of standard phosphorus; the third bell period (mid-July) dropped 10 kg of standard nitrogen plus 3 kg of standard phosphorus; the fourth time in late July dropped 8 kg of standard nitrogen.
V. Irrigated conventional irrigation, generally see irrigation head water during flowering (mid-to-late June), sandy land and poorly-fertilized land slightly ahead of schedule, and the lower tide is slightly later, with head water of 667 square meters filling 70-80 cubic meters, Adhere to small-scale furrow irrigation, should not flood irrigation; 15 to 20 days irrigation of the second water, 667 square meters of 80 cubic meters; the third water is cotton boll period, must ensure adequate supply of water, 667 square meters of irrigation volume 70 to 80 cubic meters; the fourth water August 5 to 10, 667 square meters filling 50 to 60 cubic meters. The general time of water stoppage is August 10-15. Due to the difference in the climate in autumn every year, the time of water stoppage and the amount of irrigation should be determined scientifically. The total growth period is 280-320 cubic meters/667 square meters. The first drip of the drip irrigation plot, as appropriate, from the end of June to the mid-early period, 667 square meters is filled with 15 cubic meters; after 16 days, the second time, 667 square meters is filled with 15 to 20 cubic meters; in July, once a week , 667 square meters of filling 20 to 25 cubic meters; in August every 10 days, each time 667 square meters of 15 cubic meters; the first time in early September, 667 square meters of the amount of 10 to 15 cubic meters, the whole reproductive period of dripping The amount of 180 to 200 cubic meters.
Six, adhere to the promotion of control of the combination of control, due to seedling control (weak seedlings light control, Wang Miao heavy control), "early, light, and diligence" principle, according to the climate and field growth, as appropriate, generally in the 2 leaf 1 heart 1 Sub-adjusted, diaminos 667 square meters dosage of 0.3 to 0.5 grams; 4 leaves and 1 heart of the second tone, the amount of condensation amines per 667 square meters 0.8 to 1.0 grams; 6 leaf 1 heart to 7 leaves 1 heart 3 Sub-adjustment, 667 square meters with 2 ~ 2.5 grams of dildodomamine; 12 leaves 667 square meters with 3 ~ 5 grams of dilute amine; topping the 667 square meters with 10 grams of dildo.
7. Top dressing During the growth period, the oceanic 818 cotton from Ocean University of China was used for multiple foliar sprays. It was sprayed four times in the whole growing period, that is, in 2 to 3 true leaf stages, and every 10 to 15 days thereafter. Once, they are all sprayed with 600 times liquid (mixed with potassium dihydrogen phosphate, dilute amine and pesticides) to promote robust plant growth, promote the development of bolls, and effectively prevent and suppress the occurrence of cotton blight and verticillium wilt. It also supplements the supply of nutrients during the flowering period to prevent and reduce premature aging.
Eight, pruning and shaping
1. Topping Usually on July 10th, 7-8 sticks of fruit trees hit the top 1 leaf 1 heart, hit 2 leaves 1 heart when beaten, and destroyed the heart and leaves to bury deep in the field.
2. Hit the tip of the group after playing for 10 days and hit the tip of the group.
3. The line of pruning is severe, and the shaded area of ​​the cotton field can be cut off at the end of July and early August. The shade can be severely cut to remove the bell-free fruit branches, hitting the old leaves at the bottom, and turning the plants into a cylindrical and transparent state through pruning.
9. Pest Control
1. Disease prevention and treatment with the dressing element of the dressing element of the sea 818 can significantly reduce the occurrence of rot disease in the seedling stage. It can effectively prevent, inhibit the withered and yellow wilting by spraying more than 818 cotton from the sea chestnut. Infected with the disease, the yellow wilt strain was removed during the bud and flowering period.
2. Integrated pest control eliminates earthworms and shovels, removes earthworms, reduces survival rate of overwintering earthworms of the cotton bollworm, strengthens investigation of pests at the seedling stage, and combines the first chemical control with insecticides to control cotton aphids. Check, wipe, pick, pull, coat, drip" prevention and control methods, strict control of cotton aphid, red spider development and proliferation, placing syrup bottles, frequency vibration insecticidal lamp, lure tigers overwintering, cotton bollworm adults. We should do a good job in the investigation and spotting of red spiders in buds during the bud period, and use special acaricides. We must continue to do well in the trapping and killing of insect pests, as well as the control of locusts in greenhouses and land vegetables, and eliminate locusts that occur in cotton fields. During the flowering and bolling period, it is lighted, poplar, and tamed with corn. It is also possible to use BT biological agents to prevent and control cotton bollworm. With special acaricides, spider mites are controlled at the stage of spotting; abamectin and urine mixture are used. Control locusts.
