During the cultivation season, green broccoli can be cultivated in spring and autumn. Autumn crops were planted in the middle of July and planted in the middle and early August and harvested in the middle and late October.
Soil preparation, fertilization, and colonization of green cauliflower have a strong growth potential and require a large amount of fertilizer, and must be combined with site preparation to apply base fertilizer. General Mushi quality circle fertilizer 5000 kg, decomposed manure dry 500 kg -1000 kg, superphosphate 30 kg -40 kg, 50 kg of plant ash. After applying basal fertilization, plough deep and plow it, and then level it down to make it 1.3 to 1.5 meters wide. When the green cauliflower seedlings grow to 5 - 6 leaves when the colonization, usually 2 rows per plant, plant spacing 30 cm -40 cm, planting density of about 2500 per mu; about early maturing varieties can be closely planted to about 3000 per acre It is appropriate.
Fertilizer management Green cauliflower like fertilizer, timely fertilizer and watering in phases is the key to good quality and high yield. The type of topdressing fertilizer is mainly nitrogen fertilizer, and it enters into the formation period of flower bulbs.

When harvesting, cut off the flower bulb with a flower stem about 10 cm below. After the bulb was harvested, the axillary buds of the plants germinated, and the lateral branches quickly emerged. The flower buds were formed at the top of the lateral branches, ie the lateral flower bulbs. When the flower bulbs grow to a certain size and the buds are not yet open, they can be harvested again. In this way, generally can be harvested 2 times -3 times.
