| 摘 要： | 按照生态农业理论和抗旱节水技术要求,对棉花抗旱品种、不同密度、不同基肥N、P的施用量进行田间综合试验,采用正交设计法。3年试验研究结果表明:密度以每公顷种植7.5万株比4.5万株、6万株平均增产671.85kg、483.30kg,增产57.49%和41.36%。品种陕402(早熟)、陕576(中早熟)分别比中棉所19(中熟)增产16.62%和16.17%,具有较强抗旱性。磷酸二铵比尿素增产作用明显,每公顷施150、225kg分别增产11.35%和10.53%。

| Abstract: | In accordance with the theory of agricultural ecology and the requirements of water-saving technology, drought-resistant cotton varieties were comprehensively examined at different plant densities and different basal nitrogen and phosphorous rates. The results of the three-year experiment indicated that compared with the yields at 45000 plants per hectare and 60000 plants per hectare, the cotton yield at 75000 plants per hectare increased by 671.85kg and 483.30 kg, or by 57.48% and 41.36%, respectively. Compared with the yield of Zhongmian 19(middle maturity), the yields of Shan 402(early maturity), and Shan576 (middle early-maturity) increased by 16.62 % and 16.1%, respectively. Compared with urea, diammonium phosphate increased cotton yield by 126kg and the two fertilizers at the rate ranging within 150~225kg per hectare increased cotton yield separately by 11.35% and 10.53%. |
