When it comes to coriander, everyone is familiar with it. It is a seasoning vegetable that we often eat in our daily life. It is also particularly hardy, and it has the effect of stomach and digestion. It is very popular among people. In recent years, there are more and more farmers who grow coriander, so how can coriander produce high yield?
1, variety selection
Coriander has large leaf varieties and lobular varieties. The large leaf variety has high plant height, large leaves and high yield. The lobular varieties have short plants, small leaves, strong aroma, cold tolerance, strong adaptability, and slightly lower yield. At present, there are more farmers cultivating lobular varieties.
2, seed treatment
Due to the hard shell of the seed, the conventional method is slow to sow the seedlings. Before seeding, the seeds can be spread on the flat ground, evenly hardened with less hard utensils, and the shell can be ruptured, and then directly sown (also can be soaked and germinated) ), usually about 8-13 days after the seeding.
3, choose the land, apply fertilizer, finely
Coriander has a short growth period, a strong root and a shallow root vegetable, and the bud has a soft top force and a strong ability to absorb fertilizer. You must choose to use the early tomatoes, cucumbers, beans, etc. in the loam with good drainage, fertile and loose, water and fertilizer.耙 耙 平 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , ,
4, planting time should be appropriate
It can be planted in spring, summer and autumn. The sowing period in autumn is the best after mid-August, and the quality of production is also good.
5, field management
In order to create suitable growth conditions for coriander, it is necessary to carry out several detailed cultivating, loosening and weeding work. When the seedling grows to about 3cm, it is necessary to carry out the seedlings and seedlings.
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 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 it is broadcast or spread, the soil is no longer cultivated, but we must pay attention to the removal of weeds.
6, watering management
Coriander is not drought-tolerant, and must be gently watered every 5-7 days. It is basically to 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 acre is used to ensure good growth.
7, timely harvest
Coriander is harvested for about 30-40 days at high temperatures and 40-60 days after sowing at low temperatures. Can be harvested multiple times, or harvested at one time.
The above is the key point of planting techniques for high-yield coriander. The cultivation of coriander is relatively simple, but farmers should also pay attention to prevent pests and diseases. I hope the above can help farmers.
