Arugula belongs to the warm climate of leafy vegetables, like light, but the light conditions are not strict, in the medium light conditions, fast growth, like moist soil conditions, the most suitable temperature for the growth of stems and leaves during the day for 18 ℃ ~ 23 ℃, the night for 10 ℃ or so, the adaptability of the soil is more extensive. Keep the soil moist during the growth period, to small watering principle. Greenhouse cultivation should pay attention to the regulation of temperature and light, winter to increase the temperature insulation, arugula seedlings with 2 ~ 3 leaves can be combined with young plants harvesting seedlings and seedlings.
Arugula is a half-hardy vegetable, preferring a warm and humid climate. Prefer moist soil conditions, growing in hot and dry conditions, the leaves are pungent and bitter. Like light, but the light conditions are not strict, in the medium light conditions fast growth, good quality.
The adaptability of the soil is wider, saline and alkali resistance is stronger, most suitable for planting in loose, fertile, watering and drainage capacity are good plots; need nitrogen, phosphorus and potassium fertilizers with the application, can not be a single application of nitrogen fertilizers, and then supplemented with a small amount of copper, iron, zinc, and other trace elements of the fertilizer, if necessary.
Seedling:
Generally use direct seeding, strip sowing or sowing. When sowing, you can mix 2 to 3 times the fine soil with the seeds before sowing, sowing, compression, and cover a thin layer of fine soil, watering thoroughly. In dry areas, it is best to cover the beds with black shade netting or other mulch to moisturize the soil after sowing. Remove the mulch after the seedlings emerge from the soil.
Pursuing fast-acting fertilizer
After the completion of inter-seedling depending on the plant growth potential of fertilizer, fertilizer to urea or compound fertilizer and other fast-acting fertilizers, fertilizer every 7 days. In the harvest before 5 to 7 days should not be re-training.
Small water watering
Keep the soil moist during the growth period, except for rainy days, to water every day, to small water watering as a principle, do not prolonged soil drought, and do not large water irrigation, the leaves in the cool and moist environment of fast growth, taste aromatic, no bitter taste.
Mid-tillage weeding
Seeding 4 days after sowing seedlings, 3 to 4 true leaves can be combined with the young plant harvesting of inter-seedling and seedling fixing, seedling fixing spacing 20 cm. Pull out the weak seedlings, poor seedlings. Combined with inter-seedling, shallow plowing once, and then plowing 1 to 2 times
Temperature management
Protected cultivation should pay attention to the regulation of temperature and light, winter, early spring cultivation in the air temperature is lower than 10 ℃, small arches or greenhouses to increase the temperature and heat preservation. Summer and fall to take cooling measures, in the summer 11 a.m. to 3 p.m. roof covered with shade net, or with corn, sorghum and other high-straw crops for intercropping, often foliar water spraying, in order to reduce the temperature and shade.
Pest control
Aphids. In the vegetable field intervals laid silver gray film or hanging silver gray film strips to avoid aphids. Hanging yellow boards in the field coated with sticky glue to trap winged aphids, or 20 cm from the ground to set up yellow pots, filled with 0.1% soap water or washing powder water to trap winged aphids.
Scientific harvesting: Rocket grows rapidly, timely harvesting is the key to yield, generally batch and sub-harvesting of leaves, shoots or the whole plant. The method of harvesting by cutting or splitting leaves can realize multiple harvests in autumn and winter, and leave the stubble about 1cm when cutting, and don't cut off the shortened stems.
