1, characteristics. Malan like cool and humid climate, seed germination temperature 20-25 ℃, plant growth temperature 15-22 ℃. Temperature below 15 ℃ slow growth, high temperature leaves easy to fibrosis, quality deterioration. Underground creeping rhizomes can withstand temperatures below -7 ℃. Prefer sufficient sunshine, drought tolerance is very strong, do not choose the soil, to all types of soil adaptability is very strong, cultivation of fertile soil can improve product quality.
2, reproduction methods. Malan can be reproduced by seed or by dividing the plants, and the growth is fast by dividing the plants.
3, sowing. Seeds can be sown in the fall or spring. Seeds can be sown in the open ground after harvesting in the fall, but the seedlings do not appear that year, and only after the rain in the following spring do they appear one after another, so it is better to sow in the spring. In March-May sowing. Suitable for strip sowing or sowing. Strip sowing row spacing of 30 cm, open a shallow ditch about 1 Xia meters. After sowing, only need to trample the border soil or tips plus compression, watering, and keep the soil moist. In the appropriate temperature and humid conditions, about 10 days after sowing seedlings. Seedling period to remove weeds in the field. Seedling growth is slow, spring sowing until the fall to grow into. When it grows up, you can pick the heart harvest, and will be too dense plants transplanted to other plots.
4, the use of wild planting propagation. Spring digging and plucking wild Malan planted vegetable garden fertile ground, regular watering, so that the soil "see dry, see wet", the following year, that is, a lot of creeping rhizomes. Stolons can be intercepted at any time, planted in holes or planted at a distance of 30 x 30-50 centimeters. After the summer and fall will grow into a piece, can be divided again. The planting of sufficient base bar.
5, field management. Field management is relatively simple, according to the growth situation, appropriate irrigation, fertilizer, growing season, fertilization 2-3 times, each time per mu with urea 8-10 kg, potash 2-3 kg. Spreading dry fertilizer during the winter. In summer, if there is a draw of blossoms, cut the blossom branches if they are not harvested. Marjoram has not been found to have pests and diseases, early spring drought areas if you can irrigate early, it is earlier than all other open field crops germination and growth, early market.
6, harvesting. Wild marjoram is usually picked for food in April-May in spring and October-November in fall. Cultivated Malan spring sprouting growth of about 12 centimeters when the picking, into a clump of growth can be cut with a knife, leaving a stubble of 3-5 centimeters. There are new shoots growing out that is to stay three or four leaves to pick the tip. After picking the fast-acting nitrogen fertilizer, you can continue to grow and harvest.
Malan left seed plants should not pick the tip, summer did not bloom. Seeds in September successive maturity, the head of the green to yellow-brown to be harvested in a timely manner.
