When will winter cabbage be harvested?

The harvest time of autumn Chinese cabbage in northern China is generally from after beginning of winter to around Xiaoxue solar term. Stacking is the storage mode of Chinese cabbage in northern China where the temperature is relatively high, such as Shandong and Henan. Generally, it can be piled indoors or in the outdoor corridor. Cabbage storage is afraid of freezing and the temperature is too high. Cabbage is easy to rot after freezing, which affects eating.

The harvest time of autumn Chinese cabbage in northern China is generally from after beginning of winter to around Xiaoxue solar term.

During this period, the daytime temperature in northern China dropped to 5-6 degrees, and the lowest temperature at night was near zero. You can decide the harvest time according to your local temperature change and the growth of Chinese cabbage.

Generally speaking, the harvest of rural Chinese cabbage in Shandong, Henan and other areas is basically in the middle and late period of 1 1, around the light snow solar term; Beijing, Tianjin, northern Hebei, etc. Generally, Chinese cabbage is harvested around beginning of winter in early 165438+ 10.

The harvest time of Chinese cabbage in northeast and northwest areas such as Liaoning, Jilin, Heilongjiang and Inner Mongolia is earlier, and it is usually harvested at the end of the first frost solar term 10.

Variety, harvest time and pre-harvest management of Chinese cabbage have great influence on overwintering storage.

Generally speaking, a straight tube is more resistant to storage than a ball; Green cabbage is more storable than white cabbage varieties. Late-maturing varieties are more resistant to storage than early-maturing varieties.

Stop irrigation one week before cabbage harvest, otherwise the tissue will be crisp and tender, with high water content and vigorous metabolism, which will easily damage the leaves, cause rot and affect storage.

In rural areas, Chinese cabbage should be dried and pruned before storage. After the cabbage loses 65,438+00% water naturally, the leaves with pests and diseases should be removed, and the leaves without strings outside should be picked and stored.

According to the local temperature and family situation, the main storage methods of Chinese cabbage are stacking, cellar storage and refrigeration.

1, stacking

Stacking is the storage mode of Chinese cabbage in northern China where the temperature is relatively high, such as Shandong and Henan. Generally, it can be piled indoors or in the outdoor corridor.

Cabbage storage is afraid of freezing and the temperature is too high. Cabbage is easy to rot after freezing, which affects eating. However, when the temperature is too high and exceeds 5 degrees, the respiration is too strong, which will consume too much nutrients and water in Chinese cabbage and affect the taste and storage time.

Cabbage should be properly covered to keep warm according to the change of temperature. When the temperature is high, it can be poured out to dissipate heat, and the rotten cabbage should be checked and removed in time.

2. Pit storage

The temperature in the northeast and northwest is very cold in winter, and vegetables such as cabbage and potatoes are stored in vegetable pits in many places. During storage, the vegetable trees should be ploughed frequently, and the yellow gang, rotten leaves or diseased trees should be removed in time.

Early storage period of Chinese cabbage in cellar

From storage to heavy snow or winter solstice, during this period, the outdoor temperature and the temperature in the cellar are high, and the metabolism of vegetable trees is relatively strong. Measures such as more ventilation and frequent watering of vegetables should be taken to cool down and dissipate heat.

Mid-term storage period

From winter solstice to spring, that is, from late February of 12 to early February of the following year. During this period, the temperature is the lowest, and the breathing intensity of Chinese cabbage is also weak. Pay attention to anti-freezing work. There is no need to be so diligent every time you pour food.

Late cellar storage period

After beginning of spring, that is, after mid-February, the outdoor temperature gradually became warmer. At this time, Chinese cabbage gradually aged, its quality declined, and its heat resistance and disease resistance gradually weakened. Pay attention to heatstroke prevention and prevent cabbage from rotting, and pick out soft and rotten cabbage in time.

Step 3 refrigerate

Refrigeration is a professional vegetable storage method, which can control the storage environment more effectively, but it also increases the storage cost, and is suitable for professional vegetable buyers.

Cabbages should be bagged and stacked in batches to avoid sudden increase in storage temperature and affect storage quality. There should be a gap between the basket and the pile to facilitate inspection, and the vegetables should be watered 1 time every 20 days or so. Cabbage can be stored in the cold storage for the longest time until May of the following year.
