Su Mian 28 is a new strain of insect-resistant hybrid cotton selected and cultivated in the coastal areas of Jiangsu Province. It has characteristics of large peach, high-yield, moderate ripening period, good yield and stability, high fiber quality, and resistance to insects and diseases. It passed through Jiangsu in 2011. The province has been approved and is suitable for planting in mild disease areas and non-wild wilt areas in Jiangsu province. Variety characteristics Sumian 28 has better seedling emergence, strong growth, and good uniformity; plant type is loose, stems are thick, hairiness is small, leaves are large, leaves are dark, the bells are oval, and the flocculation is smooth; fruit branches are thick and elastic. , The level is clear, the fruit branch is longer, the fruit section is more, the air is clear and light is good, it is favorable to the upper, middle and lower three peaches to be tied together, the bell in the middle and lower part is strong, the bell in the upper part is good, not premature. Regional average test results: growth period 135 days, plant height 113.9 cm, 18.5 plant branches per fruit, 27.7 bolls per plant, single boll weight 6.3 g, 42.1% lint, sub-finger 10.2 g, pre-frost flower rate 88.6 %. 2008-2009 participated in the regional trial in Jiangsu Province, the average yield of 233.9 kilograms of seed cotton for two years, an increase of 2.3% over the control Noza 3; 97.9 kilograms of lint per mu, an increase of 1.6% over the control. In 2010, the average production per mu was 226.2 kg of seed cotton, which was 2% higher than the control; 91.8 kg of lint was produced per mu, 2.6% less than the control. Inoculation identification by the plant nursery of Jiangsu Provincial Academy of Agricultural Sciences: Fusarium wilt disease index 14.4, Verticillium wilt disease index 37.3, resistance to wilt disease. Anti-cotton bollworm. Cultivation points (1) timely planting. Seedlings of the pods should be sown at the end of March and the beginning of April, and double membrane seedlings can be used as a condition. Covered mulch film sowing in mid-April. (2) Proper close planting. Equal spacing planting, row spacing of 0.8 to 1 meters; wide and narrow row planting, small row spacing of 60 cm or more. Seedling transplanted per acre planted 1600 ~ 2200, covering the film live broadcast 2200 ~ 3000 per acre. (3) Scientific fertilization. During the whole growth period, 22-25 kg of pure nitrogen, 7-8 kg of phosphorus pentoxide and 15-18 kg of potassium oxide were used per acre, and an appropriate amount of multiple microelement fertilizer was sprayed. The general fertility period applies 4 times of fertilizer: 20 kg of compound fertilizer per acre is used in combination with soil preparation before transplanting; 10 kg of urea per acre is used as a seedling raising fertilizer after live planting; in the early July and the end of July, flower bell fertilizer is applied twice. Urea 15 kg and 10 kg per mu. Former crops are rice or soil with high soil fertility and good cotton growth, and the second flowering boll fertilizer can be applied or not applied. On the contrary, the field with insufficient stamina can be covered with top dressing fertilizer as appropriate, applying 5 to 10 kg of urea per acre. (4) Timely top. Good growing fields in normal years are topping before and after August 5th. (5) Moderation. During the whole growth period, the use of methionidone was adjusted 3 to 4 times. The amount of pure drug per mu was 1 gram for budding stage, 2 grams for early flowering period, 2 grams for full flowering period, and 3 grams for 5 to 7 days after topping. According to the growth of plants and weather conditions, the amount and frequency of appropriate additions and deletions should be based on the principle of “less, lighter, and more diligentâ€.
