3. Intermediate ploughing and weeding: Cassia seed should be weeded frequently after seedling emergence and before row closure, soil consolidation should be ploughed in time after watering and rain, and pay attention to shallow hoe between plants and deep hoe between rows. Cultivating soil during the last intertillage when the seedling height is about 40 cm can prevent lodging.

4. Timely topdressing: before closing the row, Cassia seed was fertilized for 1 or 2 times combined with soil topdressing, applying 1000 kg of farm manure per mu, adding 15 kg urea, and watering immediately after application.
