The invention belongs to the technical field of
crop seedling raising methods, and particularly discloses a
root growth promoting agent suitable for rooting of sliced ginger, a ginger
slicing seedling raising method and application. According to the method disclosed by the invention, before ginger planting, a
root growth promoting agent is used, the
root growth promoting agent comprises a 200-fold diluted solution of
naphthalene B
sodium nitrate, a 500-fold diluted solution of a
microbial agent polyglutamic acid, a 500-fold diluted solution of
plant rooting
powder and a 10000-fold diluted solution of
mepiquat chloride, and the four components realize synergistic interaction, so that the comprehensive indexes of the aboveground part of the ginger
cut-block
seedling, the
plant growth amount and the seedling
root system are optimal. According to the method, intensive early seedling raising is achieved through dicing, the ginger field planting time is shortened by more than 50 days, and
crop rotation is facilitated; seedlings are neat and consistent, the root activity is high, the field
survival rate and mechanical operation of the seedlings are improved, and the labor efficiency is improved. The technical method is simple, the production cost is low, the seedling rate is high, and direct
economic benefits are embodied in production.
