The invention discloses a new
nutrient solution
seedling raising method of
Ligustrum japonicum'Howardii', which adopts the technical scheme that
seedling raising pools are designed to be 1m wide and 0.2m deep, with no limitation on the length (determined according to the field condition), and the interval between the pools is 0.4m; plastic folding frames are arranged in the
seedling raising pools to serve as carriers to support the seedlings; and the
nutrient solution at the initial stage is
ferrous sulfate with the concentration of active substance being less than 0.05%. A proper amount of
nitrogen-
phosphorus-
potassium mixed
fertilizer can be added after new roots grow out one month after
cutting, and the concentration of total active substance is still no more than 0.05%. The new soilless seedling raising method includes the steps of: before
cutting, selecting an annual half lignified
branch at length of 10-15cm with 2-5 leaves at the upper part;
cutting out one third of each leaf through scissors; soaking the cutting wood in alpha-
naphthylacetic acid at concentration of 20mg / L for 20-30 seconds; setting up sunscreen
canopy frames outside the seedling raising pools and covering sunshade nets or
straw mulch on the sunscreen
canopy frames; and obliquely cutting the cutting wood on the plastic folding frames. According to the method disclosed by the invention, the
nutrient solution is simple to prepare, wide in source of
raw material and low in cost, and the carriers for supporting the seedlings are durable in use and convenient to use. Tests show that the
survival rate of the seedlings reaches above 90%, and labor cost and production material cost can be saved by more than 700RMB per 10 thousand seedlings.
