The invention discloses a growth regulator for early pregnant Zizania latifolia. The growth regulator is Zengyinling. Its concentration is 20 mg/L. The spraying method of growth regulator consists of the following steps: 1) selection of stubble: selection of stubble with normal stubble and similar shape in stubble field, planting in late March, and conventional field management; The preparation of growth regulator dilution solution: weigh Zengyingling, pour it into beaker, weigh alcohol in dosing barrel to dissolve, prepare mother liquor and dilute it with clear water when used; 3) Spray: Spray growth regulator dilution solution on the leaf and sheath of Zizania latifolia at five-leaf stage, spray once every 10 days, continuously. Continue spraying 2 times. The invention provides a growth regulator for early pregnant stubble and its spraying method, which can make the stubble get pregnant earlier, improve the pregnant stubble rate, and have excellent indexes such as effective tillering rate and net stubble weight. At the same time, it can also ensure that the yield and quality of the stubble are greatly improved.

一种提早茭白孕茭的生长调节剂及其喷施方法
本专利技术属于农作物生产
,具体涉及一种提早茭白孕茭的生长调节剂及其喷施方法。
技术介绍
茭白(Zizanialatifolia)为禾本科菰属多年生宿根草本植物。茭白孕茭与其内生的菰黑粉菌(Ustilagoesculenta)侵染互作密切相关。菰黑粉菌侵染茭白成功后,茭白开花受到抑制,茎基部膨大形成可食用的肉质茎。若菰黑粉菌未能侵入植株,新生腋芽则成为不能形成产品器官的雄茭。若菰黑粉菌菌丝潜育期缩短过早形成冬孢子则产生不能食用的灰茭,植株生长和分蘖趋于衰退。研究认为,菰黑粉菌的侵入刺激了茭白促进生长的内源激素含量发生明显变化,内源激素含量水平的变化是茭白植株进入孕茭阶段及茭茎膨大生长的内在原因。有人发现,细胞分裂素作用于细胞分裂,在茭白膨大过程中起了重要的作用;生长素和赤霉素GA3能够促进发育早期茭白植株根的生长,有利于茭白吸收土壤中养分,并增强光合作用,促进茭白株高的增加。研究还发现,茭白孕茭及膨大期间脱落酸含量很低。这可能与脱落酸对病原菌的抗性有关,较低的脱落酸含量可降低植株对病原菌的抵抗作用,这利于菰黑粉菌的侵 ...
