郸城县是我省重点植棉县之一,常年植棉30万亩左右。但种植的多是70年代和80年代初推广的品种,产量不高、品质较差,抗病性不强,不能满足生产发展的需要。为了解决这一问题,我们通过调查,引进了豫棉4号新品种。试验结果证明,豫棉4号株型较紧凑,叶片大小适中,透光性能好,茎秆坚韧,抗倒伏,比一般中熟品种早熟3—5天,这些特性正适合我县麦棉套种对棉花品种的要求;二是高产、稳产、丰产性能好;三是纤维品质好,原棉洁白有丝光,手感光滑有弹性;四是抗逆性强,具有抗枯萎、耐黄萎,耐苗期黑根病,耐盐碱等特性。
Dancheng County is one of the key cotton planting counties in our province, about 30 million acres of cotton planting perennial. However, most of the cultivated varieties are popularized in the 1970s and early 1980s. The yield is not high, the quality is poor, the disease resistance is not strong, and the production can not meet the needs of production. In order to solve this problem, we through the investigation, introduced a new variety Yu-4. The test results showed that Yumian No.4 was more compact with moderate leaf size, good translucent performance, stalk toughness and lodging resistance, 3-5 days earlier than other medium maturing varieties. These characteristics are suitable for the cotton-cotton intercropping Cotton varieties of the requirements; the second is high yield, stable yield, good yield performance; third is good fiber quality, raw cotton white and mercerized, feel smooth and flexible; Fourth, strong resistance to wilt, resistant to wilt, yellow seedling tolerance Root cause, salinity and other characteristics.
