摘 要：
通过大田试验,研究耕作和施氮方式对红优2号产量和纤维品质的影响,试验设3种耕作方式,即免耕(A)、垄耕(B)和深松耕(粉垄)(C);3种施氮方式,即T1(20%作基肥,80%作为追肥)、T2(40%作基肥,60%作为追肥)和T3(60%作基肥,40%作为追肥)。共9个处理组合。结果表明,1免耕和垄耕时,AT1和BT3处理纤维产量、种子产量、纤维强力、回潮率均达到最大值;2深松耕时,CT3处理纤维产量、纤维强力、回潮率均达到最大值,线密度达到最小值,CT2处理种子产量达到最大值;3与免耕相比,深松耕的纤维产量、种子产量、纤维强力分别增加21.0%、19.1%和12.7%,线密度下降14.0%。当追求纤维产量和品质时,采用CT3组合,此时纤维产量、纤维强力和回潮率均达到最大值,线密度达到最小值;追求种子产量时,宜采用CT2组合。

摘 要：
Three tillage methods including(A) no tillage,(B)ridge tillage and(C)subsoiling tillage(Fenlong) and three fertilization methods including T1(20% N fertilizers as basal fertilizer, 80% N fertilizers as topdressing), T2(40% N fertilizers as basal fertilizer, 60% N fertilizers as topdressing) and T3(60% N fertilizers as basal fertilizer, 40% N fertilizers as topdressing) were conducted. The results showed that the fiber yield, seed dry mass, fiber strength, rate of moisture regain of AT1 and BT3were the maximum in no tillage and ridge tillage. In subsoiling tillage, the fiber yield, fiber strength, rate of moisture regain of CT3 was the maximum. The linear density of CT3 was the minimum. The seed yied of CT2 was the maximum. Compared with no tillage, the fiber yield, seed dry mass, fiber strength, linear density of Hongyou 2 in subsoiling tillage treat increased by 21.0%, 19.1% and 12.7%, respectively. The linear density reduced by 14.0%. It is indicated that the treatment of CT3 has best fiber yield and quality. The treatment of CT2 has high seed yied.
