Field management of mustard planting

Mustard is the most common pickle in our daily life. we like to put a little mustard in everything we do, which is loved by many people, but mustard is actually processed with shepherd's purse head. Therefore, the cultivation of mustard head determines the quality of processed products, but also related to their own economic interests. It is not only necessary to have a correct planting method, but also need good field management after planting, so as to ensure the good growth of mustard and obtain high yield. The following brings you the field management method of mustard.

1. Fertilization

There is a principle of fertilization, that is, the first is light and the second is heavy, that is, light fertilization should be applied before the beginning of winter. if the base fertilizer is sufficient, the plants with good growth can not be fertilized before winter. the main purpose of applying winter fertilizer is to prevent the overwintering from being damaged by low temperature and freezing. After the Beginning of Spring, the temperature rebounded, the growth rate of mustard became faster, and the demand for fertilizer gradually increased, so heavy fertilizer should be applied to meet the growth needs of mustard. Early application of swelling fertilizer such as farm manure can promote the expansion of tubers and reduce the hollow heart rate. Pay attention to topdressing, foliar fertilizer and supplement of trace elements.

2. Moisture

Mustard is a kind of vegetable with high water demand. If it encounters drought or high temperature in summer before winter, it should be watered according to the specific conditions of the border. In case of continuous rainfall, the drainage ditch in the field should be opened in time, the soil should be loosened, the stagnant water in the field should be discharged, and the waterproofing work in the field should be done well. After the Beginning of Spring, the temperature began to rise, along with the advent of spring rain, if there is no timely drainage, resulting in too much water in the field, high humidity, high temperature and high humidity is the most likely to cause diseases, so drainage and ditching in the field should be done in time.

3. Disease control

There are many diseases of mustard, mainly virus disease and soft rot, especially virus disease, which is the most harmful to mustard mustard. First of all, the biggest cause of virus disease is because of the occurrence of aphids. In order to thoroughly control virus diseases, we must first control the occurrence of aphids, which can be controlled by virus A spray. Soft rot mainly occurs in the seedling stage and expansion period, the prevention and control of soft rot can use plague cream solution. Insect pests are mainly aphids, yellow striped jumping beetles and so on. Pests are most harmful at seedling stage and early planting stage, and can be controlled by aldicarb, dichlorvos and other agents.

4. Timely harvest

The harvest time of mustard is also particularly important, too early and too late will have an impact on mustard to a certain extent, the party will lead to excessive maturity of mustard, leading to cracking problems, but also more likely to cause diseases. Early harvest will lead to mustard not mature enough, need to be stored for a period of time, improper management in the storage process is also more likely to cause diseases, and affect the time to market. Therefore, the most suitable harvest time is before and after Ching Ming Festival, which not only does not affect the maturity, but also ensures the quality of its mustard. Reasonable interplanting techniques can also be used to increase or decrease production.

The above is the field management when planting mustard. When planting mustard, we must pay attention to the management of the field, pay attention to the harm of diseases and insect pests, and choose a suitable planting method. 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 diseases, which do the greatest harm to mustard mustard. So everyone must pay attention.
