How to carry on the field management when the cabbage heart stage enters the critical growth period?

Abstract: the heart stage of Chinese cabbage has entered a critical period of growth, how to carry out field management?

The cabbage heart period is an important period for the growth of cabbage. If the cabbage is well managed in this period, the yield of cabbage can be high in the later period, so the management of cabbage in this period is very important. Here, Science Xingnong will discuss with you the field management of cabbage heart period.

The growth stage of Chinese cabbage

First of all, let's take a look at the growth stage of Chinese cabbage. The growth stage of Chinese cabbage is generally divided into five stages: germination stage, seedling stage, rosette stage, heading stage and dormancy stage. Among them, the heading period is what we often call the cabbage heart period, which is the period when the heart leaves of Chinese cabbage begin to close gradually, and it is also an important period for cabbage management. Generally, the heart period of early-maturing cabbage is about 20 days, and that of late-maturing cabbage is about 40 days. The heading period can generally be divided into three periods: the front, the middle and the back.

Key points of management in heading and pericardium period of Chinese cabbage

Water, the most important thing in the process of planting and management of Chinese cabbage is the problem of water. The water demand of cabbage entering the heart stage increases, so we should pay attention to watering to avoid the occurrence of water shortage or unstable watering in the heart stage of cabbage. The first watering of Chinese cabbage after entering the heart stage is best irrigated with small water to avoid affecting the root system of Chinese cabbage due to excessive watering.

The second watering usually takes place about four to five days after the first watering. At this time, you can water a little more, and then water every five days or so. Watering is best carried out by furrow irrigation, which can reduce the root rot of cabbage caused by too much watering. In addition, watering should be stopped about a week before cabbage harvest, which is convenient for later storage and harvest.

Fertilizer, fertilizer problem is also one of the important issues of cabbage heart period, this period of cabbage fertilizer demand is still quite large, this period is generally divided into two times of topdressing. The first topdressing in the early stage of cabbage heading period, you can use urea about 10 kg per mu, and combined with the use of calcium superphosphate about 7 kg per mu, potassium sulfate about 8 kg per mu. After the cabbage enters the middle stage of the heart, topdressing can be carried out for the second time, and about 10 kg of ammonium sulfate can be applied per mu, and fertilization can be combined with watering. Finally, when you enter the later stage of the heart, you can reduce or no longer carry out topdressing, so as to avoid overgrowth or root burning of cabbage.

Bundling cabbage, cabbage heart period can be timely bundled vegetables, so as to avoid the freezing injury of Chinese cabbage, and facilitate late harvest and storage. However, it should be noted that the bundling time of cabbage should be reasonable, not too early or too late. It is usually carried out two weeks before cabbage harvest.

The last is the need for growers to harvest in time, the general temperature is about 5 degrees when the harvest can be carried out, the time is usually around the beginning of November.
