Coriander cultivation method
First, choose fertilization site preparation
The parsley has a short growing period, the main root is thick, and it is a shallow-rooted vegetable. The buds are soft, and the top soil has poor ability to suck fertilizer. The choice of soil is more fertile and has better water retention and fertilizer retention performance. Drought and energy can be used for irrigation and drought. The soil can be drained well, and the soil is loose and fertile. The soil that has not been planted with coriander for more than five years must not be replanted. You can use early tomatoes, cucumbers, beans, etc. for the former. After the harvest, the crops will be promptly removed to reduce the occurrence of pests and diseases. Deep plowing and leveling, applying 3,000-5,000 kilograms of decomposed farmyard manure for every 0.1 hectare, for pods, generally 1 metre wide, depending on the terrain, water source, and water quantity. It is necessary to facilitate plant management and promote root absorption. And the plants grow robustly.
Second, sowing
Coriander varieties are divided into large leaf type and lobular type. Leaflets have strong cold resistance, strong aromas, and can be eaten raw, seasoned, and pickled. They are suitable for fall planting. The seeds are hemispherical and covered with a layer of peel. Before sowing, seeds should be split first to prevent slow germination and twin emergence, affecting the growth of individual plants. The appropriate sowing period is in mid-August and no later than the end of August. Drilling distance 10-15 cm, deep ditch 5 cm; spread 4 cm deep ditch. Drilling and spreading are all covered with 2-3 cm. 0.1 hectares use 6-6.5 kg. After sowing, use foot to step again, then water, keep the soil moist, in order to facilitate the emergence of seedlings. At the same time, it should also pay attention to soil compaction before the emergence of parsley, seedlings do not appear on top of the phenomenon of soil, check seedlings in time after sowing, if found when the seedlings uncovered soil compaction phenomenon, must seize the time spray water to help seedlings unearthed Promote rapid growth.
Third, strengthen field management
In order to create a soft and comfortable fertility environment and conducive to the growth and development of parsley, to achieve the appropriate temperature and humidity management, careful cultivating, loosening, and weeding are key.
1. Early sparse seedlings and timely Dingmiao
When the seedlings grow to about 3 cm, the seedlings will be seedlings. Generally throughout the growing season tillage, loose soil, weeding 2-3 times. For the first time, in the top soil of seedlings, mild soil-peeling soil is used with a light hand spade or a small spade to eliminate the compacted layer. At the same time, remove the weeds that have been unearthed earlier to facilitate the growth of young seedlings. The second time when the seedling height is 2-3 cm, and the seedlings can be used as a suitable deep loose soil, combined with the removal of weeds. The third time was when the seedling height was 5-7 cm. This early cultivating, ripping and weeding can promote vigorous growth of seedlings. After the leaves have been sealed on the ground, no matter if they are drilled or broadcast, they will no longer cultivate and loosen the soil. It is only necessary to do several times to weed the grass.
2. Top dressing and watering
Before setting seedlings, generally do not water, in order to facilitate the control on the promotion, seedlings strong roots. After the seedlings are sown, the seedlings shall be poured once in a timely manner, and the amount of seedlings should not be submerged. As the seedlings thrive, the water requirement gradually increases, and the watering interval gradually decreases. It is basically 5-7 times shallow water throughout the growth period. The first three waters are poured once every 10 days or so, and they are separated by 6-7 days from Sishui. Keep the soil moist and control shallow water before harvesting.
In combination with watering, the topdressing is performed in stages, and the head water is used to recover the seedlings with light weight, and the urea of ​​Mushi is about 10 kilograms. After each 2 to 3 times of pouring water, the urea is recovered once, and 10 to 12.5 kilograms can be used.
Fourth, harvest and storage
Parsley is harvested at high temperatures, 30 days after sowing, and at low temperatures, 40-60 days after sowing. The harvest can be increased or harvested once. In addition to the recent food consumption in autumn, it can also be stored for consumption in winter and spring. Most of the storage uses buried freezing method. Before eating, put it in a place between 0°C and 10°C. Slowly relieve the freezing, and you can still maintain the tender state and the color taste will not diminish.
