When is broccoli harvested? How to harvest? What to do after harvesting?

Cauliflower is a common vegetable variety in our life. It is rich in nutrients and has a wide market and is widely grown in China. So, do you know when broccoli is harvested? How to harvest? What is the harvesting standard? The following is a small series of Huinong. I will talk about the method of harvesting broccoli and post-harvest treatment.

First, broccoli harvesting standards

Timely harvesting is the guarantee of the yield and quality of broccoli, and the number of days from the appearance of flowering to the harvest of broccoli varies by species and climate. When the temperature of the early-maturing varieties is relatively high, the flower bulbs form quickly and can be harvested in about 20 days; the mid-late maturity varieties usually take about 1 month in the late autumn and winter; and the late-maturing varieties in the spring from the current flowering balls to the harvesting needs 20 More than a day. The formation of flower balls is sometimes inconsistent between individual plants and should be harvested in stages.

The standard for broccoli harvesting is that the flower ball is fully grown, the surface is round and the edges are not yet scattered. Harvesting affects production too early, too late, the surface of the flower ball is uneven, the color is yellow, and the quality is poor.

Second, broccoli harvesting method

When the broccoli flower ball is just exposed, the leaves around the flower ball are picked up, gently tied with a straw rope, or the 1-2 leaves near the flower ball are broken and covered on the flower ball to keep the flower ball white and soft. Stop watering for 4 to 5 days before harvest.

Generally, the cauliflower flower ball is bare, the water content is high, and the texture can be harvested when the texture is crisp. Care should be taken when harvesting, lightly pick and put, choose a flower ball that is fully grown, the surface is round, and the edge flower buds are not scattered. Generally, it is harvested at 4~5 pm, leaving 2~3 rounds of leaves under the white flower ball. Cut, if used for fake plant storage, the roots should be harvested. It is not suitable for picking on rainy days.

Third, broccoli harvesting considerations

Cauliflower harvesting should be carried out on sunny days 6-7 am or 4-5 pm. It is strictly forbidden to harvest at noon, and the harvesting tools should use stainless steel knives. After loading, put it into the plastic turnover box. When placing the sample, pay attention to protect the flower ball. The basket should not be overfilled to avoid crushing the damaged flower ball. The surface of the basket should be covered with a layer of water to evaporate. It is strictly forbidden to use wicker basket or bamboo basket. Shipment. The post-harvest flower ball has a sharp increase in respiratory intensity, so it should be pre-cooled quickly.

Fourth, the processing of broccoli after harvesting

Pre-cooling allows the product to be placed in a cool, ventilated place in a natural temperature, exposed to sunlight during the day and open at night, allowing a large amount of field heat and breathing heat to be dissipated as quickly as possible. If there is a cold storage, the storage temperature can be lowered to 4-5 °C, and the ventilation facility can be enabled to quickly reduce the temperature of the food. This method is fast and stable.

The selection and dressing is to choose a flower ball with a diameter of about 15 cm, a tight ball, white, no pests and diseases, no mechanical damage, leaving 3-5 leaves, and using a stainless steel cutter to cut the lower old flower stem. When transporting with refrigerated trucks or refrigerated containers, the temperature should be strictly controlled at around 0 °C throughout the transportation process.

The above is the broccoli harvesting method and post-harvest treatment organized by Huinong. I hope to help you.
