What if the coriander doesn't emerge?

Coriander is a very common vegetable in our daily life, and it also has a very large planting area in our country. Although the planting technology of coriander is relatively simple, and the yield is also relatively high. However, when planting coriander, we often encounter the phenomenon that coriander seeds do not emerge after sowing. So what should we do if the coriander seeds don't come out? The following editor will give you a brief introduction, let's have a look!

1. Broken seed shell

The reason why the coriander seeds do not emerge may be due to the failure to break the shell of the seeds. Now there are generally two kinds of coriander seeds that have not broken shell and have broken shell on the market. If the seed has broken its shell, the seed will look fine and cracked. If there is no broken shell, the seed will be fuller and round, and the seed coat will be more smooth. Therefore, for this kind of seed, it is necessary to break the shell, knead the seed in two pieces of cardboard and other planes, or rub it in the sand. Pay attention to the strength, do not use too much force, resulting in kernel injury, to ensure that the shell can be broken.

2. Seed treatment

In order to improve the germination rate of coriander seeds, we also need to do a good job of accelerating germination after breaking the shell of coriander seeds. Wrap the seeds in a wet cloth and soak them in water for about two days, with a change of water halfway. After soaking the seeds, drain the water, then spread it evenly in a cool place for budding, keeping the temperature at about 20 degrees Celsius. Or after the seed is soaked, it can be treated at about 10 degrees for about 3 days, which can effectively improve the germination rate of the seed. At the same time, in order to avoid the harm of diseases and insect pests, we should also use new high-fat membrane and other germicidal solution for seed dressing and disinfection.

3. Sowing seeds at the right time

Cilantro can not be replanted, which will seriously affect the germination rate of parsley. Therefore, when sowing, the plot should ensure that there are no coriander plants for at least three years. At the same time, we should also do a good job in soil preparation and disinfection. Before sowing, the soil should be watered thoroughly and sufficient base fertilizer should be applied. Then break the soil to improve the softness of the soil and prepare the bed for sowing, which is very beneficial to the rooting and germination of the seeds. When sowing, you should pay attention to the weather and should not be exposed to the sun. After sowing, cover the soil and spray an appropriate amount of new high-fat film, but also cover the plastic film in the strong light environment.

4. Strengthen the management

Even after the above treatment, it takes about two weeks for coriander seeds to emerge after sowing. If there is no treatment, the emergence time may be as long as a month, and the germination rate will be greatly reduced. Therefore, if the soil is relatively dry during seedling emergence, attention should be paid to proper watering. Then watering and weeding should be done well after emergence, and proper fertilization should be applied when the seedlings grow to about 7-8 cm to improve the survival rate of the seedlings.

The above is a brief introduction to what to do if coriander does not emerge. That's all for today's introduction. This article is for reference only. I hope it can help you all.
