Why Chinese Cabbage Does Not Form a Head and How to Solve It
Chinese cabbage is the most common vegetable in our daily lives, and it is simple to grow, so everyone plants some, but many growers often encounter the phenomenon of Chinese cabbage not forming a head when growing it, which has a certain impact on the quality and yield of Chinese cabbage. So what causes Chinese cabbage not to form a head? How should it be solved? Let's take a look together with the editor.
1. Causes of Chinese Cabbage Not Forming a Head
There are many causes of Chinese cabbage not forming a head, but the main ones are actually temperature and humidity. Increased rainfall can also cause many diseases to occur, and these diseases will affect the growth of Chinese cabbage. Besides causing Chinese cabbage not to form a head, they may even cause Chinese cabbage to rot. In addition, insufficient water supply or improper fertilisation may also cause Chinese cabbage not to form a head, and another one is that pests may also cause Chinese cabbage not to form a head. After knowing the causes of Chinese cabbage not forming a head, preventive measures must be taken.
2. Solutions
1. Scientific fertilisation
Fertilisation is extremely important for any crop. In the process of growing Chinese cabbage, if fertilisation is improper, it may lead to poor growth and failure to form a head. Many people like to use nitrogen fertiliser to promote rapid growth of Chinese cabbage, but this is actually a wrong practice. Chinese cabbage fertilisation should be mainly phosphorus and potassium fertiliser, combined with a small amount of nitrogen fertiliser. Topdressing can be done 20 days after planting Chinese cabbage, then once every half month, and after heading begins, spray foliar fertiliser once every week to ensure that the head is firm.
2. Regulating humidity
Chinese cabbage needs a large amount of water during its growth period, but it should not be watered blindly. Do not water sometimes more and sometimes less; watering must be balanced, and attention must also be paid to weather changes to adjust watering appropriately. If the temperature is relatively dry, water in the morning and evening; if it rains for many consecutive days, drain water in time.
3. Controlling temperature
Chinese cabbage is mainly produced in winter, so this means it has extremely strong cold resistance, which also means its heat resistance is not very good, so when growing it, more effort must be put into temperature. For example, when growing it in a greenhouse, it can be kept in a constant temperature state, which is beneficial to its growth.
4. Preventing and controlling pests and diseases
Pests and diseases are a severe problem for all crops. Once crops suffer from pests and diseases, they will cause relatively serious consequences, and the same is true for Chinese cabbage. When Chinese cabbage is affected by pests, it will fail to form a head, so during the Chinese cabbage growing process, attention must be paid to pest reproduction, and pests must be dealt with promptly when found, so as not to miss the best time for prevention and control.
