引进6个油葵新品种进行品种比较试验,结果表明:K989和S606在覆膜和露地栽培条件下均表现高产、丰产性状好。覆膜栽培K989和S606单产较对照分别增产30.27%和26.45%;与露地栽培相比,覆膜栽培模式下K989和S606分别增产14.97%和39.10%,水分生产效率分别增加0.26kg/m 3和0.58kg/m 3,提高18.78%和51.88%。因此,S606属耐旱、节水型高产品种,K989属耐旱、高产型品种,均可作为宁夏中部扬黄扩灌区油葵主栽品种示范推广。
The introduction of six new varieties of oil sunflower variety comparison test showed that: K989 and S606 under the conditions of plastic film mulching and open cultivation showed high yield, good yield traits. Compared with open field cultivation, the yield of K989 and S606 increased by 14.97% and 39.10% and the water production efficiency increased by 0.26kg / m3 and 0.58 kg / m 3, an increase of 18.78% and 51.88%. Therefore, S606 is a drought-tolerant and water-saving high-yielding cultivar, and K989 is a drought-tolerant and high-yielding cultivar, which can be used as a demonstration and promotion of major oil sunflower cultivars in the Yellow River expansion irrigation area in central Ningxia.
