The parsley planted doesn't sprout because your method doesn't work right.

Abstract: it is difficult for coriander to germinate, so planting coriander is not only quick but also complete.

The price of parsley has soared to 39 yuan per jin this year, so that some farmers who grow parsley have tasted sweetness, and the demand for parsley in winter is also very large, so there are many friends who grow parsley. However, it is difficult to sprout after sowing, and the growth is often uneven, so how to plant coriander to ensure that it germinates quickly and emerges neatly?

What are the factors affecting the germination rate of coriander seeds?

On the one hand, it is the reason of the coriander seed itself, that is, the hard shell of the seed is difficult to permeate water, and if it cannot absorb water, it will affect the germination rate naturally; on the other hand, it is the external environmental factors, including temperature, moisture, soil, fertility, diseases and insect pests and so on. When the external environmental temperature and humidity are not suitable, coriander seeds are difficult to germinate or easy to die after germination.

What are the measures to improve the germination rate of parsley?

First, the seed breaks its shell. There are two kinds of coriander seeds sold on the market, one is that the merchant has done a shell-breaking treatment, this kind of seed looks fine and cracked. One is not broken shell treatment, this kind of seed looks plump and round, seed coat smooth, this kind of artificial broken shell. Generally, you can rub the seed between the two planes, remember not to push too hard, or rub the seed in the sand to ensure that the seed shell is broken, but do not damage the seed.

Second, seed soaking and sprouting. After breaking the shell, the seeds were wrapped with gauze and soaked in water for 1 to 2 days, and the water was changed twice in the middle. After soaking the seeds, remove and drain the seeds and spread them flat in a wet cloth bag and put them in a cool place to accelerate germination. The germination temperature is generally controlled at about 20 ℃. Observe the seed germination and sow the seeds at the right time.

In the middle, it is necessary to sprinkle water to keep the seeds moist, and some studies have said that if the soaked seeds are treated under the condition of 10 ℃ for a few days and then germinated, the germination rate of the seeds can be increased and the seeds will grow better after germination. In order to control diseases and insect pests, the seeds are usually mixed in 800-fold solution of new high-fat membrane or other bactericidal solution before budding.

Third, prepare to sow seeds. Coriander is also a crop that avoids continuous cropping, so it is best to sow land that has not been planted with parsley or celery in 3 years. Soil preparation before sowing, land preparation before sowing, sufficient water and basic fertilizer, soil moisture timely deep ploughing and loosening, making border blocks, breaking bumps, ensuring that the soil is fine and loose, virtual and solid on the border blocks, which is conducive to the rooting and germination of seeds.

Choose morning or afternoon when sowing, avoid the sun exposure, sow the seeds on the border surface, cover a thin layer of soil, after sowing, you can spray 800 times of the new high-fat film on the border surface to isolate diseases and insect pests, reduce water evaporation and maintain moisture. After sowing, it can be covered with plastic film or straw when the light is strong, so as to avoid sun exposure, and can not be covered with rotten farm manure to avoid burning seedlings.

After sprouting, the plastic film should be removed timely according to the temperature to ensure that the growth temperature is about 20 ℃, generally not less than 10 ℃, no more than 30 ℃, keep the soil moist in the early stage, and water according to soil moisture.

Fourth, field management. After the emergence of coriander, it is necessary to weed in time to prevent diseases and insect pests. After emergence, the coriander seedlings can be harvested and listed as soon as possible when the coriander seedlings are watered every 4 days according to the soil moisture.

Here is science to promote agriculture, with you to grow knowledge.
