How do you plant mustard seeds?

Mustard is usually propagated by sowing method, and there are two kinds of artificial cultivation: open-field cultivation and protected cultivation. Open-field cultivation can be carried out in both spring and autumn in the Yangtze River and Huang-Huai areas, generally mainly in autumn. It can be sowed one after another from late July to October, and the harvest ends in mid-September to March of the following year, but the yield of sowing in August is the highest. Let's take a look at how mustard seeds are planted.

Seed selection

Mustard pimple seeds with orange color, bright color is better, after the seed purchase should first be selected, in addition to cleaning up the mixed impurities, but also select full seeds, because mustard pimple seeds are small, generally through washing to select, that is, the seeds are immersed in water and constantly stirred, remove blighted seeds and sundries, dive into the bottom of the water for full seeds.

Seed drying and disinfection

After the mustard seeds were selected by water, they were spread out and exposed to the sun immediately, so as to reduce the water content in the body and turn them from time to time, so that all seeds can be evenly baptized by sunlight, promote their internal material transformation, end dormancy, and increase the germination rate. and the emergence is more consistent. Soak the seeds with disinfection fungicides such as multi-bacteria for 5 minutes for 10 minutes and stir them continuously to let the seeds come into full contact with the solution to kill all the germs.

Soaking seeds to accelerate germination

Sufficient water absorption of mustard seeds is beneficial to seed internal material transformation and seed coat softening to promote budding. as for soaking in wet water for 3 to 4 hours, comprehensive foliar fertilizer can be added to increase nutrition, increase sprouting rate and strengthen seedlings. The germination of seeds should have temperature in addition to air and moisture, so the seeds after soaking should be soaked to 25: 30 ℃ and the environment to ensure early germination and neat and uniform germination, so as to promote the management of seedling stage.

Sowing technology

Mustard is cultivated in late February in spring, from early July to late August in summer, and from early September to early October in autumn. The sowing rate is 1.5 kg / mu for spring sowing, 3 kg / mu for summer sowing and 2 / 3 kg for autumn sowing. Usually spread, but strive to be uniform, after sowing, trample the border surface gently with your feet, so that the seeds are in close contact with the soil, so that the seeds can absorb water and emerge early. Sowing in summer and autumn can be done one or two days before soil preparation, wet the land and then prepare the land for bed.

Juvenile management

The purpose of the management of mustard seedling stage is to ensure that the seedlings emerge in time, the seedlings are neat and uniform, the stem is thick, and the leaves are thick green and strong, so the main work is to keep warm and moisturizing, but not too wet, so as to avoid the lack of air and easy to rot. Another work is to pay attention to the prevention of aphids, in order to reduce the infection of germs. During the period from seedling emergence to 2 true leaves, foliar fertilizer should be sprayed twice to promote strong seedlings. At this time, the growth of seedlings should be accelerated, and seedlings should be carried out in a timely manner. Keep the seedling distance 4 cm away from the leaves to shade each other to form a merchant foot seedling, until the seedling merchant 14 cm 16 cm, with 5 cm 6 true leaves can be colonized.
