Detailed Explanation of the Key Field Management Techniques for Mustard Tuber Cultivation
Mustard tuber is the most common pickled vegetable in our daily lives. Everyone likes to add a little mustard tuber to whatever they make, and it is loved by many people, but mustard tuber is actually made by processing the stem of Brassica juncea var. tumida (mustard tuber). Therefore, the cultivation of mustard tuber determines the quality of the processed product and is also related to one's own economic interests. Not only is a correct planting method needed, but good field management after planting is also required, so as to ensure the good growth of mustard tuber and achieve high yield. Below is the field management method for mustard tuber.

1. Fertilization
There is a principle for fertilization, which is light first and heavy later, that is, light fertilization before winter. If the base fertilizer is sufficient and the plants are growing well, no fertilization is needed before winter. Applying winter fertilizer is mainly to prevent excessive growth and development, which would cause low-temperature freeze damage during overwintering. After the Beginning of Spring, the temperature rises, mustard tuber grows faster, and its demand for fertilizer gradually increases, so heavy fertilizer should be applied at this time to meet the growth needs of mustard tuber. Applying farmyard manure and other swelling fertilizers early can promote the expansion of the tuber and reduce the hollow heart rate. Pay attention to topdressing, foliar fertilizer, and supplementing trace elements.
2. Water
Mustard tuber is a vegetable with a relatively high water requirement. If drought occurs before winter or during high summer temperatures, watering should be done according to the specific conditions of the ridge surface. If continuous rainfall occurs, the field drainage ditches should be opened in time, the soil should be loosened well, the accumulated water in the field should be drained, and the waterproofing work in the field should be done well. After the Beginning of Spring, the temperature begins to rise, accompanied by the arrival of spring rain. If drainage is not done in time, causing too much accumulated water in the field and relatively high humidity, diseases are most likely to be caused under high temperature and high humidity, so the work of draining and ditching the field should be done in time.
3. Disease Control
There are many diseases of mustard tuber, mainly viral disease and soft rot, especially viral disease, which is the most harmful to mustard tuber. First of all, the biggest cause of viral disease is the occurrence of aphid pests. To thoroughly control viral disease, the first step is to control the occurrence of aphid pests, and Virus A spray can be used for control. Soft rot mainly occurs during the seedling emergence stage and the expansion stage, and Yishuangling solution can be used to control soft rot. The main pests are aphids, striped flea beetles, and so on. Pests are most serious during the seedling stage and the early planting stage, and pesticides such as pirimicarb and dichlorvos can be used for control.
4. Timely Harvesting
The harvesting time of mustard tuber is also particularly important. Harvesting too early or too late will affect mustard tuber to a certain extent. Too late will cause mustard tuber to over-mature, trigger cracking problems, and also make it relatively prone to diseases. Harvesting too early will cause mustard tuber to be insufficiently mature, requiring a period of storage. Improper management during storage also makes it relatively prone to diseases and affects the time to market. Therefore, the most suitable harvesting time is around Qingming Festival, which neither affects maturity nor fails to ensure the quality of the mustard tuber. Reasonable intercropping techniques can also be used to increase or decrease yield.
The above is the field management for cultivating mustard tuber. When cultivating mustard tuber, be sure to manage the field well, pay attention to the harm of pests and diseases, and choose a planting method suitable for yourself. Then, with proper field management, there will basically be no problem in achieving high yield. Among these, special attention should be paid to aphids, because aphids not only harm the plants but also indirectly cause viral disease, and viral disease is the most harmful to mustard tuber. So everyone must pay attention.
