When will the Chinese cabbage be harvested?

As a kind of vegetable, Chinese cabbage is very common on people's dinner table. It is very rich in nutrients and is welcomed by many people. At present, there are many varieties of Chinese cabbage, and the harvest time varies with different varieties. The common ones are summer Chinese cabbage and autumn Chinese cabbage. So when should Chinese cabbage be harvested after planting? The following editor will give you a brief introduction, let's have a look!

1. Harvest standard

Time is very important when Chinese cabbage is harvested. If the harvest time of Chinese cabbage is early, not only the yield will decrease, but also the quality of sugars and other nutrients in Chinese cabbage is low and the storage resistance is poor. According to a survey of professional data, in mid-November. If you harvest one day every night, the average yield can be increased by about 700 jin / mu. Therefore, it is appropriate to harvest Chinese cabbage late, but the harvest should not be too late, otherwise Chinese cabbage is vulnerable to freezing damage. It should be fully harvested when the temperature drops to minus three degrees at the latest.

2. Harvest time of summer Chinese cabbage

Summer Chinese cabbage is generally the most standard planting variety, whether sowing or harvesting, the temperature during which is more suitable for the growth of Chinese cabbage. Therefore, the sowing time will be a little longer, and the sowing time can also be changed appropriately. When planting summer Chinese cabbage, its main purpose is to meet the market and consumers' demand for Chinese cabbage. Therefore, the sowing time of summer Chinese cabbage is generally from May to June, and the harvest time is from July to August. However, it is also necessary to choose the appropriate planting time and sowing time according to the characteristics of the planting variety.

3. Harvest time of autumn Chinese cabbage

The harvest time of autumn Chinese cabbage is equivalent to that of summer Chinese cabbage, and its requirements are relatively strict. The growing period of autumn Chinese cabbage is relatively short, and the heading period is relatively fast, and if it is a mid-late mature variety and needs to be stored in winter after harvest, it should be harvested before and after Lesser Snow solar terms in the north. In the middle of November, the weather is relatively good, and there is no need to harvest at this time, so as to prolong the growth period of Chinese cabbage and enrich the leaf ball. Cabbages that need to be stored in winter should be harvested in late November to prevent freezing damage caused by strong cold currents.

4. Matters needing attention in harvesting

When harvesting Chinese cabbage, it should be picked at the right time according to the variety. For example, if it is a precocious variety, it is usually harvested after the bulb is formed. If the market is hot at the end of autumn, it can be picked and listed before the leaf ball is fully tight. For middle and late maturing varieties, the longer the growth period is, the more mature the leaf ball will be and the yield can be increased. Therefore, we had better delay the delivery time as far as possible, but it should be noted that Chinese cabbage can only withstand light frost, and freezing damage will occur if the temperature is two degrees below zero.
