Causes and control measures of bolting of mustard

Mustard belongs to Brassica vegetables of Cruciferae, which is widely planted in China, but the bolting phenomenon in the planting process will directly affect the high nutritional value and commercial value of mustard, and bring great losses to growers. So what is the cause of mustard bolting? Let's get to know it.

1. Bolting reason

Mustard, especially mustard, is one of the main processing vegetables currently used to make salted vegetables. It can be produced all year round with a balanced supply, not just a crop planted in autumn. Therefore, in the late spring or summer and other unsuitable seasons, buried in this long sunshine climate conditions, mustard obtained the conditions for flower bud differentiation and germination, it will be very easy to bolting and flowering. In addition, in the case of poor fertilizer and water conditions and low level of management, it will also lead to premature bolting.

2. Preventive measures

According to the local climatic conditions and cultivation time and environment, the suitable varieties resistant to bolting should not be introduced blindly. In the case of direct seeding, the varieties with verrucous stem as oblate shape should be selected. Sowing time can avoid or shorten the high temperature and summer drought weather which is disadvantageous to the growth of mustard, which is beneficial to the early bolting control of the plant. For precocious cultivation at high elevations, mulching must be adopted to raise seedlings. The method is to cover the seedlings with a sunshade net with a shading rate of more than 95% at noon every day for 3-4 hours until the rice is complete, and at the same time, there is an adequate supply of fertilizer and water to prevent mustard from bolting due to lack of nutrition.

3. Prevention and control methods

For fresh mustard which is provided for processing on time, the cultivation season and climatic conditions can not be changed. The method of early harvest can be adopted, that is, it can be harvested before leaf mustard bolting. Although the yield is low, it can ensure the quality and minimize the loss.

The above is the introduction of the causes and control measures of mustard bolting. I hope it can help you. If you want to know more about it, please follow us.
