Detailed Explanation of Management Techniques for Black Locust (Robinia pseudoacacia) at the Seedling Stage
The management method for black locust at the seedling stage is: when the seedlings are 3 to 4 cm tall, carry out the first thinning; afterwards, based on the growth of the seedlings, carry out 1 or 2 more thinnings, with the final thinning carried out when the seedlings are 10 to 15 cm tall; after final thinning, leave about 10,000 plants per mu. Black locust is susceptible to waterlogging, so drainage should be carried out promptly after heavy rain. After the young seedlings grow 3 or 4 true leaves, apply a chemical fertilizer as a top dressing, and apply another top dressing in July; after August, generally no more irrigation or fertilization is done.
