摘要
通过比较木薯单独、混合喷施S3307、6-BA、4-PU以及KH2PO4的产量、品质效应,寻求木薯高产优质的生长调控技术。结果表明:单独喷施S3307处理木薯茎宽、块根长、半径、单株结薯数及单株块根干重均较大,每667m2产量达到4372.30kg,比清水对照增产44.33%。单独喷施KH2PO4有利于木薯淀粉积累,淀粉含量为24.6%,且降低块根含氮化合物含量。喷施S3307、6-BA、4-PU、KH2PO4以及复配剂效果显著,木薯产量、淀粉含量均较高。6-BA、4-PU调控效果不显著。因此,木薯可通过喷施S3307、KH2PO4的生长调控措施,达到高产优质的目的。
This paper through spray S3307,6-BA,4-PU and KH2PO4 alone or mixture, tiT to find the cassava growth regulate technology for high yield and quality, the result are： the effect of 6-BA ,4-PU are not significant. S3307 treatment yield 4372.30 kg per 667 m^2,significantly increase cassava production by 44.33%. KH2PO4 increases the starch content and reduce the nitrogen-containing compound of Cassava tuberous roots. The mixture treatment significantly increases cassava production and starch content. Therefore, spraying S3307 and KH2PO4 can increases cassava production and starch content.
