Field management of the latest mustard planting

Pickled vegetable is the most common pickle in our daily life. Everyone likes to put a little pickled vegetable in everything, which is loved by many people, but pickled vegetable is actually processed with shepherd's purse. Therefore, the cultivation of pickled mustard tuber determines the quality of processed products, and it also relates to its own economic interests. Not only should there be a correct planting method, but also good field management after planting, so as to ensure the good growth of pickled mustard tuber and obtain high yield. The following brings you the field management method of pickled mustard tuber.

1. Fertilization

Fertilization has a principle, that is, light before heavy, that is, light fertilization before winter, if the base fertilizer is sufficient, the plant growth is better before winter can not fertilize, winter fertilizer is mainly to prevent rapid growth and cold damage during winter. After the beginning of spring, the temperature rises, the growth speed of pickled mustard tuber becomes faster, and the demand for fertilizer also gradually increases, so heavy fertilizer should be applied to meet the growth demand of pickled mustard tuber at this time. Early application of farm manure and other expanding fertilizer can promote tuber expansion and reduce empty heart rate. Pay attention to topdressing, foliar fertilizer, supplement trace elements.

2. Water

Pickled mustard is a vegetable with high demand for water. If it encounters drought before winter or high temperature in summer, it should be watered according to the specific conditions of the ridge surface. In case of continuous rainfall, the drainage ditch in the field should be opened in time, the soil should be loosened, the accumulated water in the field should be drained, and the waterproof 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 there is no timely drainage, it will cause too much accumulated water in the field, and the humidity is too high. Under the condition of high temperature and high humidity, it is most likely to cause diseases. Therefore, the drainage and trenching work in the field should be done in time.

3. Disease control

There are many diseases of pickled mustard tuber, mainly virus disease, soft rot, especially virus disease, virus disease is the greatest harm to pickled mustard tuber. First of all, the biggest cause of virus disease is because of the occurrence of aphids. If you want to completely control virus disease, you must first control the occurrence of aphids, and you can use virus A spray to control it. Soft rot mainly occurs in the emergence period and expansion period, control soft rot can be used Yishuang Ling liquid medicine. Insect pests are mainly aphids, yellow curve jump A. Insect pests are most serious at seedling stage and early stage of planting, and can be controlled with insecticides such as aphiridin-resistant and dichlorvos.

4. Timely harvest

The harvest time of pickled mustard tuber is also particularly important. Too early or too late harvest time will affect pickled mustard tuber to a certain extent. Too late harvest time will lead to excessive maturity of pickled mustard tuber, causing cracking problem and easy to cause disease. Early harvest will lead to immature mustard tuber, need to store for a period of time, improper management in the storage process is also easy to cause disease, and affect the time to market. Therefore, the most suitable harvest time is around Qingming Festival, which will not affect the maturity, but also ensure the quality of pickled mustard tuber. Reasonable interplanting techniques can also be used to increase or decrease yield.

The above is the field management when planting pickled mustard tuber. When planting pickled mustard tuber, we must pay attention to the field management, pay attention to the harm of diseases and insect pests, and choose the planting method suitable for ourselves. And then do a good job of correct field management, so that there is basically no problem with high yield. Special attention should be paid to aphids, because aphids not only harm plants, but also indirectly cause virus disease, virus disease is the greatest harm to pickled mustard tuber. So please pay attention.
