Preservation method of edible fungi. When will broccoli be harvested?

Where there is sowing, there is harvest, and we must harvest broccoli at the right time. If it is harvested too early, the buds of broccoli are not fully developed and can not reach the standard of the finished product; if harvested late or in case of high temperature, broccoli will appear scattered flowers and may turn yellow. In broccoli, we should pay attention to water supply. If the quality becomes worse, it will lose its commodity value. Let's take a look at when to harvest broccoli, the time to harvest broccoli and the method of harvesting broccoli.

The harvest time of broccoli is that the flower bulb is fully grown, the bud grain is neat, the ball is not scattered, and when it does not bloom, the quality and yield are the highest. In general, the appearance of all the buds of the precocious varieties are the same, the buds feel a little thick, and the edge buds are slightly loose. When the middle and late maturity varieties touch the flower ball by hand, they feel convex and uneven, and when the buds grow very compact, it is the most suitable time for harvest. The harvest time of broccoli is relatively strict. If the harvest is too late, the pedicel will elongate, resulting in the disintegration of the flower ball and affecting the quality. Especially in the high temperature environment, if the buds are not harvested in time, the buds will turn yellow and lose commodity value.

When the bulb of broccoli grows to 12-15cm, the buds have not been loosened, the whole bulb remains tight and intact, and the harvest time is bright green. If the water is irrigated once every 2 days before harvest, the quality and output of goods can be improved. It is better to harvest in the early morning and evening. When harvesting, there are 4 leaves around the bouquet, and the lower part of the bulb is cut together with the flower stem 10cm to protect the bouquet. In most varieties, after the top bulb is harvested, the axillary buds of the plants germinate, and lateral branches grow rapidly, and a lateral flower bulb is formed at the top of the lateral branches. when the lateral corms grow to a certain size and the buds are not yet open, they can be harvested for 2-3 times one after another. Broccoli tissue is crisp and tender, harvesting and handling should be handled lightly, and the bouquet must be put on the market in time or refrigerated immediately after harvest.

The use of all kinds of pesticides is prohibited two weeks before harvest. The method of artificial harvest is adopted, and the harvest is the best in the early morning and evening. The harvest standard is: the export standard is determined according to different requirements, the general bouquet is 11.5-14 cm, the length of the wreath stalk is not less than 16 cm, and the weight is 100 g-200 g. The color is thick green, the flower ball is compact, the flower shape is round, the flower bud is relatively uniform and delicate, there is no full sky star (yellow grain), scorched bud, rot, no insect population, no live worm, no damage, no handle hollow and other abnormal phenomena. Harvest domestic market sales (domestic sales) standards are: flower ball diameter 12-18 cm, flower ball stalk length not less than 14 cm, weight in 400-600 grams. The color is thick green, the flower ball is compact, the flower shape is round, the flower bud is not yellow, scorched bud, no insect population, no live worm, no serious damage. To ensure that there is no mechanical damage in the process of transportation, each basket is filled with 14-16 bouquets, and the leaves are covered against sunscreen and bruises. Sunshade net should be put on after loading to prevent long transportation time from sun exposure, loading and unloading and handling gently.
