Coriander, with a special aroma, is generally used for eating. Stems and leaves are used as vegetables and spices, and have stomach and digestion effects; fruits can be extracted with aromatic oil; coriander seeds contain about 20% oil. The economic value is high, so what should you pay attention to when planting coriander? The following introduction is for your reference only.
First, the cultivation of coriander is suitable for temperature: coriander is also known as glutinous rice, which is a cold-tolerant vegetable. It is cold and cool, and the growth temperature is 12°C-26°C, but the heat resistance is also strong.
Second, the requirements of coriander on the soil: soil conditions are not strict on the soil, but the loam with high organic matter content is more conducive to the growth of coriander.
Third, the treatment of the seeds before the coriander planting: due to the hard shell of the seed, the conventional method of seedlings is slow, the seeds can be spread on the flat ground before planting, evenly hardened with less hard utensils, the shell is broken, then Can be directly sown (can also be soaked and germinated), usually about 8-13 days after emergence.
Fourth, the variety selection of coriander: there are large leaf varieties and lobular varieties. The large leaf plant has high plant height, large leaves and high yield; the small leaf plant is short, the leaves are small, the aroma is thick, the cold resistance is strong, the adaptability is strong, and the yield is slightly lower. There are many varieties of cultivated lobules.
Fifth, the cultivation method of parsley: acre of farmer's fertilizer 2000-3000 kg, 10 kg of diammonium phosphate, 10 kg of potassium sulfate, deep turn, leveling the ground. Use strip or spread, strip and spread are covered with soil 2-3 cm, and 3-4 kg per mu. After the sowing, use your foot to rub it again, or use a leveling tool to suppress it, then water it to keep the soil moist to facilitate emergence.
At the same time, it should be noted that due to the soil compaction before the coriander is unearthed, the phenomenon of unearthing at the top of the seedlings occurs. After the sowing, the seedlings should be checked in time. If there is soil compaction when the seedlings are unearthed, it is necessary to take time to spray the loose soil to help the young shoots. Unearthed to make it grow normally.
6. Planting time of parsley: It can be planted in spring, summer and autumn. The suitable suitable sowing period in autumn is after mid-August, and the quality of production is better.
7. Daily management after the cultivation of coriander: In order to create suitable growth conditions for coriander and to meet the conditions of suitable temperature and humidity, it is necessary to carry out several detailed cultivating, loosening and weeding. When the seedlings grow to about 3 cm, the seedlings and seedlings are carried out.
Generally, the cultivating, loosening, and weeding are carried out 2-3 times throughout the growing season. For the first time, when the seedlings are topped, use light hand rubs or small tweezers to gently soil the loose soil and eliminate the knot layer.
At the same time, the unearthed weeds were removed to facilitate the emergence of seedlings. The second time is carried out when the seedling height is 2-3 cm, and the strip can be used to properly loosen the soil and combine the weeds. The third time was carried out at a seedling height of 5-7 cm. Such early cultivating, loosening, and weeding can promote the vigorous growth of seedlings. After the leaves are sealed on the ground, no matter whether they are sowing or spreading, they will no longer cultivate the loose soil, but pay attention to the removal of weeds.
8. Water management of coriander: Coriander is not drought-tolerant. It must be lightly poured once every 5-7 days. It should be watered 5-7 times during the whole plant growth period to keep the soil moist. In the middle of the fertility period, about 10 kg of urea per mu is used to ensure good growth.
