step 3, controlling the sowing season: the sowing time is from 4 months bottom to 5 months (spring and summer) of the solar calendar or from 11 months to 12 months (11 months to 12 months) of the solar calendar;
the key point of the cultivation of the golden panda tree seedlings is to control the sowing season; the seeds are mature in 4 months, and the germination time, the emergence time, the germination rate and the seedling growth vigor are all good by adopting the sowing time.
At the two time points, the temperature in the south is averagely 20 ℃, so that the germination of the matured seeds is suitable, and tests show that the germination is fast, the seedling emergence time is short, and the seedling growth vigor is good; in early spring and winter, the sowing temperature is low, particularly the low-temperature cold damage in winter and the late spring cold seriously affect the germination and emergence time of seeds, even the seeds are frozen and rotten to death.
Step 4, sowing: the height of the seeding and seedling raising bed is 20-25 cm, and the width of the seeding and seedling raising bed is 0.8-1.0 m. Sowing is carried out in a broadcasting manner, and the sowing quantity is 120-150 kg/hm2(about 3000 seeds per kilogram).
