What's spicy in the countryside?

The spicy food in rural areas is mustard, which belongs to Brassicaceae and Panicum. Its height can reach 150 cm, and its young stems and leaves are prickly and spicy. Stem erect, leaf blade stalk with lobules; The lower leaves of the stem are small, with serrated or serrated edges, and the upper leaves of the stem are narrow and lanceolate, with inconspicuous sparse teeth or entire edges.

Mustard likes cold and wet environment, likes to avoid heat and drought, is not resistant to frost, and needs strong light. Bud pregnancy, vine pulling, flowering and fruiting all need low temperature vernalization and long sunshine conditions. Its root system is developed, and the main lateral roots are distributed in the soil layer of about 30cm. I like chemical fertilizer, and I have a great demand for NPK fertilizer. Mustard has a short growth period, from sowing to harvesting for about 30 days, and can be harvested when the leaves are 10- 12.
