摘要
在不同密度条件下,对沈爆3号爆裂玉米的产量、品质和生理指标做了研究。结果表明,叶绿素含量、单株叶面积随密度的增加而降低,叶面积指数增大;生物产量和子粒产量的变化趋势则明显不同,在3000~3600株/667m2范围内随密度的增加而增加,而在3600~4500株/667m2的生物产量、经济产量和品质变化并不很大,表现出该品种适合密植并在高密度下有较强的自动调节能力。沈爆3号在3600~4500株/667m2时,产量在408~415.5kg/667m2,膨胀倍数30以上,爆花率98%以上。
Yield and quality and physiological index of Shenbao No.3 were researched in different plant density. It showed as a result chlorophyll content and area of leaf increased with density increase Variety current of biological material and grain was different it is increased with density increase in range 3 000 ~ 3 600 plants per 667 m2 but not different in range 3 600 - 4 500 plants per 667 m2. It indicated that Shenbao No.3 self-regulation ability is strong in high density. The yield had reached 410 kg/667 m2 the popcorn expand times is above 30 pop-rate is 98% when 3 600 - 4 500 plant per 667 m2.
