Introduction to new cotton products
Hongliangyou No. 5 rice
Hongliangyou No. 5, a new high-yielding hybrid indica rice variety bred by Nanjing Red Sun Seed Co., Ltd., is produced by the breeding unit.
Characteristics: Hong Liangyou No. 5 has 160,000 to 180,000 effective ears per mu, with an ear length of 24 to 25 centimeters, an average number of grains per panicle of about 160, and a thousand-grain weight of about 30.1 grams. The reproductive period is similar to that of Shanyou 63. It grows gracefully and matures well.
Key points of cultivation: Proper sowing and planting period: Arrange the sowing and planting period according to the local optimal heading period. Seed soaking technology: Dry the seeds for 1 to 2 days before soaking; clean the seeds during soaking and remove the empty and shriveled seeds; advocate soaking seeds in running water. Reasonable dense planting: 15,000 to 18,000 holes per acre and 40,000 to 60,000 basic seedlings. Fertilizer and water management: The amount of pure nitrogen applied per mu of large fields should be slightly higher than that of Shanyou 63, and should be combined with phosphorus and potassium fertilizers. Apply the fertilizer and water management technology of early promotion, mid-term control and final stability. In the later stage, the main application is wet, dry and wet, and avoid cutting off water too early. Pest and disease control: timely prevent and control pests and diseases according to the occurrence of local diseases and insect pests.
Nankang No. 9 cotton
Hongliangyou No. 5, a new high-yielding hybrid indica rice variety bred by the breeding unit, Nanjing Red Sun Seed Co., Ltd.
Characteristics: Moderately early maturing, with a full growth period of about 128 days. The plant is tower-shaped, with strong boll-forming ability, early onset but no premature senescence, large bolls, a single boll weighs about 6.7 grams, high lint content, and smooth flocculation. Highly resistant to Fusarium wilt and Verticillium wilt.
Key points for cultivation: seedlings should be sown with dry seeds in early April (do not soak seeds). Transplanting: Select strong seedlings for transplanting. Density is determined based on soil fertility and stubble. Fertilizer and water: Apply enough base fertilizer, apply flower and boll fertilizer early and heavily, supplement the top fertilizer, and apply an additional 10 to 20 kilograms of potassium fertilizer in early August. Water in time in case of drought. Adjustment: In the early stage, the peach growth is fast and can be controlled lightly; in the later stage, it is used scientifically depending on the situation of the seedlings, natural conditions and density. Pest control: Pests such as cotton aphids and cotton spider mites must be controlled with timely pesticides.
Suitable areas are suitable for planting in the cotton areas of the Yangtze River and Huanghuai River basins.
Suza 118 cotton
The breeding unit Suza 118 is a new hybrid cotton variety carefully selected and bred by the Economic Crop Research Institute of the Jiangsu Academy of Agricultural Sciences for many years.
Features: High yield and stable yield. The average yield of seed cotton and lint cotton per mu in the two-year regional trial increased by 12.20% and 9.28% respectively compared with the control. The average yield of seed cotton per mu in the large-scale production demonstration reached 325 kilograms, and individual fields could reach more than 350 kilograms. It has strong resistance to adverse weather conditions, stable and increased production. Great potential; strong ability to form bells. The bells are larger, with a single bell weighing about 6.1 grams, oval, with thin shells and smooth vomiting; strong disease resistance. Resistant to fusarium wilt and resistant to verticillium wilt.
Key points for cultivation: seedlings should be sown with dry seeds in early April (do not soak seeds). Transplanting: Select strong seedlings for transplanting. Determined based on density, soil fertility, and stubble. In pure cropping fields, 1,200-1,600 plants should be planted per acre, and in intercropping fields, the number should be reduced accordingly according to the intercropping mode and varieties. Fertilizer and water: Apply enough basal fertilizer, apply flower and boll fertilizer early and heavily, add top fertilizer, and increase phosphorus and potassium fertilizer. Water in time in case of drought. Chemical adjustment: Use scientifically based on seedling conditions, weather conditions and density. Pest control: Pests such as cotton aphids and cotton spider mites must be controlled with timely pesticides. In years when cotton bollworm occurs more heavily, pesticides should be used for control.
