三年来的生产示范表明,Ⅱ优501在六安地区连续三年平均单产为8599.5~9324kg/hm2,比汕优63分别增产10.61%~13.27%,且出米率达71%,含直链淀粉18.55%、粗蛋白9.72%、粗脂肪3.2%。同时通过品比试验、示范研究与制种摸索,了解了其株高111.5cm、穗大粒多、生育期142天左右,属中籼迟熟类型。提出了Ⅱ优501的高产种植技术与制种技术要点:母本5月上旬播种,8月上中旬扬花;父母本播差期3~6天,母本播种112~150kg/hm2;父母本行比1∶10~12或2∶12~14。肥床旱法育秧,秧龄25~30天,株行距为13.3×25cm或16.7×20cm,30穴/m2。
Three years of production demonstration shows that Ⅱ You 501 in Lu’an for three consecutive years the average yield of 8599.5 ~ 9324kg / hm2, respectively, than Shanyou 63 yield 10.61% ~ 13.27%, and the rice rate of 71 %, Containing 18.55% amylose, crude protein 9.72%, crude fat 3.2%. At the same time through the ratio test, demonstration research and seed production groping, understand its height 111.5cm, spike large grain, growth period of about 142 days, is a late indica type. Proposed Ⅱ You 501 high-yielding planting techniques and seed production techniques: female parent in early May sowing, in August on the middle of the flowering; parents of the sowing period of 3 to 6 days, the mother seeding 112 ~ 150kg / hm2; parents Bank Than 1:10 ~ 12 or 2:12 ~ 14. Fertilizer bed dry law seedlings, seedling age 25 to 30 days, spacing of 13.3 × 25cm or 16.7 × 20cm, 30 holes / m2.
