[Network] agricultural harvest have sown there, for broccoli we must timely harvest, if harvested too early, broccoli buds have not fully developed, not up to the standard of the finished product; harvested late or in case of hot weather, West orchid will scatter flowers and possibly yellow, effectively noting that the water supply should be in broccoli. If the quality deteriorates, it will lose its commodity value. Here we take a look together at what time harvesting broccoli, broccoli harvest time and method of harvesting broccoli.
The harvest time of broccoli is that the flower ball is fully grown, the flower bud particles are neat, the ball is not scattered, and the quality and yield ZUI are high when not blooming. Generally, the appearance of all early-maturing varieties is the same, the flower buds are slightly thicker, and the small flower buds are loose when they are loose. The middle-late-maturing varieties touch the flower ball by hand and feel uneven. When the flower buds are very compact, they are harvested. Receive ZUI period. The harvesting period of broccoli is relatively strict, and the harvesting is too late, the peduncle will elongate, causing the flower ball to disintegrate and affect the quality. Especially in high temperature environment, if it is not harvested in time, the flower bud will turn yellow and lose the value of the commodity.
Wait until the broccoli flower ball grows to 12-15cm, the small flower buds have not been loosened, the whole flower ball remains tight and intact, and it is suitable for harvesting when it is bright green. If the water is poured once every 1-2 days before harvesting, the quality and yield of the product can be improved. The harvest is good in the morning and evening. When harvesting, 3 to 4 leaflets are kept around the flower ball, and the lower part of the flower ball is cut with 10 cm of the flower stem to protect the flower ball. For most varieties, after the top ball is harvested, the axillary buds of the plants germinate and rapidly grow side branches, and side flower balls are formed at the top of the side branches. When the side flower balls grow to a certain size and the flower buds are not yet open, they can be harvested. This can be harvested 2-3 times in succession. The broccoli tissue is crisp and tender, and should be handled with care and handling. After harvesting, the flower ball must be listed for sale or immediately refrigerated and fresh-keeping.
