When are the seeds of coriander planted? How long does it take to sprout? How?

Coriander is a common vegetable in daily life. It is widely used as seasoning because of its special aroma. At present, it has been planted in many areas, but if you want to grow cilantro well, you need to know the planting time and technology. When will the coriander seeds be planted? How long will it take to sprout? How do you plant it?

Planting time of coriander:

Cilantro can be planted all the year round, but it is usually planted in spring and autumn, so now it is possible to grow coriander. Now more autumn coriander is planted in September, but those heat-resistant varieties can also be planted in August, the budding rate can not achieve a very good effect, but the benefit is good! In addition, as the northern saying goes, there are two-volt vegetables with turnips on the head, and coriander can also be planted with cabbage, but the seedlings emerge slowly, so moisturizing measures need to be taken, such as covering wheat, orange, hay and so on.

How long does it take to sprout?

Usually, parsley will sprout in a week or so. The specific time depends on the temperature and humidity. Annual or biennial, strongly scented herbs, 20-100 cm tall. The root is fusiform, slender, with many slender branches. The fruit is round, and the main ribs and adjacent secondary ribs are obvious on the back. The ventral surface of the endosperm is concave. The tubing is not obvious, or 1 is located below the secondary edge. Flowering and fruiting period from April to November.

How do you plant it?

1. Seed treatment

Select high-quality varieties, soak the seeds in 15 ℃-20 ℃ water for 24 hours (change the water once in the middle), control the excess water out, put it into a wet cloth bag, then put it into the pit to accelerate germination for one day and night, and then mix with the new high-fat membrane 800x solution (seed dressing with new high-fat film can ward off underground diseases and insects, isolate virus infection, do not affect germination and swelling function, strengthen respiratory intensity, and improve seed germination rate) Then sow seeds on the flat border surface, sow an appropriate amount of seeds, and cover the thin sand fine soil slightly on the soil surface sprayed with 800 times of the new high-fat film, which can protect moisture and evaporation, sun and drought resistance, heat preservation and freezing, soil layer hardening, suffocation and isolation of disease and insect sources, and improve the emergence rate.

2. Sowing seeds

The growth period of coriander is short, but the main root is strong, it is a shallow root vegetable, the ability of top soil is poor, and the ability of absorbing fertilizer is strong. Fertile land must be selected for the cultivation of coriander, which is beneficial to the planting management of coriander, and then promote the absorption of root system and the robust growth of plants.

3. Planting

The planting of parsley can be divided into two types: large-leaf cilantro and small-leaf cilantro. Small-leaf parsley is suitable for planting in autumn, and the suitable planting period is in the middle of August. The row spacing of strips is 10m ~ 15cm, the depth of trenching is 5cm, and the depth of planting is 4cm. Pay attention to watering and keep the soil moist to facilitate seedling emergence. At the same time, we should also pay attention to the phenomenon that the top of the seedling is not unearthed due to the soil consolidation before the coriander is unearthed, and check the seedlings in time after sowing. If the phenomenon of soil consolidation is found when the seedlings are unearthed, it is necessary to spray water to loosen the soil in order to help the young buds unearthed and promote rapid growth.

4. Field management

In order to create a soft and comfortable growth environment and living conditions conducive to growth and development of coriander, and to achieve the management of temperature and humidity, careful ploughing, soil loosening and weeding are the key. The seedlings are fixed when the seedlings grow to about 3 cm. Generally, there are 3 times of ploughing, loosening soil and weeding during the whole growing period. At the top of the seedling soil for the first time, a light pickaxe or a small rake was used to slightly break the soil and loosen the soil to eliminate the plate layer. At the same time, pull out the weeds unearthed early to facilitate the seedlings to thrive. The second time is carried out when the seedling height is 2mi 3cm, and the strip sowing can be sown with a small flat hoe to loosen the soil properly, combined with pulling out weeds. The third time was carried out when the seedling height was 5ml / 7cm. In this way, early ploughing, loosening the soil and weeding can promote the vigorous growth of seedlings. After the leaves are sealed on the ground, no matter it is sowing or sowing, they will no longer plough and loosen the soil, but just pull the grass several times purposefully. Parsley is not tolerant to drought, so it must be watered gently every 5 murals every 7 days. Basically, the whole plant is watered for 7 times during the growth period, and the soil is often kept moist. In the middle growth stage, 0.1 ha topdressing 15 kg of urea to ensure good growth.

Coriander seed sprouting time is relatively fast, as long as a good grasp of the temperature and humidity in the air on the line. When dealing with the sprouting of coriander seeds, it is necessary to isolate the insect source and pathogen, so as not to cause the survival rate of planting in the later stage. After you have done this, you only need to choose an appropriate time to plant.
