Intertillage and weeding: after the seedlings are unearthed, loosen the soil in time to weed, and cultivate the soil around the seedlings properly in combination with loosening the soil to keep it loose and weed-free, weeding 3-4 times a year.

Fertilization irrigation: topdressing 10- 15cm when the seedling height 1 5 cm, and the application rate per mu 1500-2000 kg of human and animal manure. From the end of June to the beginning of July, 20 kg of calcium superphosphate and 5 kg of urea were topdressing per mu, furrowing between rows, covering soil and watering.
