Early nursery, nursery seedlings early February early in the greenhouse with the lower part of the rooting powder soaked, heat up the root, to be callus formation, roots began to appear when the nutrition bag cultivation. Seedlings to enhance temperature and fertilizer management, to promote strong seedlings. 2. Early planting, reasonable close planting In early May, when the seedlings have been 3 to 5 leaves for transplanting, the density of 2.5 × 1 m or 2 × 1 m is appropriate. According to the density of the first dig 60 × 60 × 45 cm planted pit, organic fertilizer per pit with 10 to 15 kg and fill with soil mixing, and then filled with fertilizer garden soil pit.
