ask:
May I ask how can mint be grown?
First, nursery
l, rhizome reproduction. Breeding roots are carried out in late April or late August. In the field, plants with strong growth and no pests and diseases were selected as mother plants, and planted at a plant spacing of 2010 cm. After harvesting the stems and leaves on the ground in the early winter, the rhizomes remain in situ as seed plants.
2, ramets breeding. The seedlings of peppermint are about 15cm high, and should be mixed with seedlings and seedlings. Use the intercropped seedlings to transplant.
3, cutting propagation. From May to June, the shoots on the ground were cut into 10 cm long cuttings. On the whole seedbed, the cuttings were planted at a row spacing of 73 cm. After rooting and germination, they were transplanted to the field.
Second, transplanting
1. Mint is transplanted before the germination in the early spring of the second year, early planting and early germination, long growing period and high yield. When planting, the roots are excavated, and the roots with thick, internodes and disease-free roots are selected for rooting, cut into 7-10 cm long sections, and then the line is 25 cm apart on the whole surface, and the groove of 10 cm depth is opened. The roots were placed obliquely in the ditch at a depth of 10 cm to cover the soil, step on the soil, and water.
2, topping the top, when the plant grows vigorously in May, it is necessary to pick up the top bud in time to promote the growth of the side branches and leaves, which is beneficial to increase production.
Third, the head knife period management (emergence to the first harvest)
1. Check the seedlings for planting. After the seedlings are basically in the field, the seedlings should be checked in time, and the spots and pieces lacking seedlings or seedlings should be replanted.
2, cultivating and weeding. After the whole seedling, inter-row cultivating and weeding, artificial weeding between plants to protect the pupa, increase (ground) temperature, eliminate weeds and promote seedling growth. Weeding and weeding 2-3 times before the closure. Remove the weeds in the field before harvesting to prevent the smell of other weeds from affecting the quality of the peppermint oil.
3, timely topdressing. When the height of the seedling is 10-15cm, the ditch and topdressing are applied, and 10 kg of urea per acre is applied. After the sealing, 5 ml of sprayed Shibao potassium dihydrogen phosphate 150 g of urea 150 g twice is sprayed.
4. Scientific watering. In the middle and middle stages of peppermint, there is more water, especially in the early stage of growth. The root system has not yet formed, and it needs more water. Generally, water is poured for about 15 days, and water is poured 4-5 times from emergence to harvest. After sealing, it should be lightly poured in order to avoid the stems and leaves being mad and falling, causing the lower leaves to fall off and reduce the yield. Water is stopped 20-25 days before harvest. It is advisable to whitish the ground when harvesting.
5. Disease prevention and treatment. The main disease of mint is black shank, which occurs in the seedling stage. The symptoms are that the base of the stem shrinks and dents, turns black, rots, and the plants fall and wither. In the prevention and treatment period, 70% chlorothalonil or 40% carbendazim 100-150g can be sprayed with water during the onset period.
1 mint rust, easy to hair from May to July, sprayed with 25% powder rust 1000-1500 times liquid.
2 Spot blight, occurring from May to October, spraying 65% of the Dyson zinc 500 times solution at the beginning of the disease, which can be controlled once a week.
6. Pest control. The main pests of mint have bridge-building insects, and the damage period is around mid-June and around the end of August. Generally, the density of insects is 10 heads/m2, and 15-20 ml of enemy can be killed per acre, sprayed 1-2 times, or sprayed with 80% dichlorvos 1000 times.
7. Harvest at the right time. At the beginning of July, when the 10%-30% flower buds of the main stem of the mint were in full bloom, harvesting began. When harvesting, the upper stems and leaves should be cut off, and the cut mint is immediately spread out to dry, and no backlog can be accumulated to avoid fermentation. Mint harvesting will reduce the oil yield too early, and the harvest will be too late, and the content of menthol furan will increase, which will affect the quality of the oil. The dried mint is bundled in time and used for distillation and refining.
Four, two knife period management (after the first harvest to the second harvest)
1. The second-stage mint has a short growth period. After harvesting the head knife, it is necessary to promptly clean up the leaves for distillation and refining. The wreckage, weeds and stolons on the ground (usually 2-3 cm deep) should be removed as soon as possible to promote the emergence of the shoots of the -TJ seedlings from the rhizome.
2. Immediately after the wreckage, watering should be carried out to promote the early growth and rapid growth of the second knife seedlings, prolong the growth time and increase the yield. Watering 3-4 times in the second knives period, 10-15cm in seedling height, l0kg of urea in the mu (grain), 1-2 times in the foliar application, 1-2 times in the grass before harvesting, so that there is no miscellaneous in the field before harvesting. grass.
V. Harvest
1. Harvest time is from mid-September to mid-October.
2, when the sun is 7-8 percent dry, tie into a small handle, and then dry to dry. The leaves are full of leaves, the leaves are dark green, the stems are purple-brown or light green, and the aroma is better.
