Cultivation techniques of coriander

Coriander is a special vegetable and one of the main side dishes in our country. Parsley has a very wide range of distribution, and it can be seen almost all over the country. Now the market demand of coriander is expanding, and the market price also has a rising trend. So how do we grow parsley? The following editor brings you the planting technology of coriander, let's have a look!

1. Cultivation methods

The cultivation methods of coriander can be divided into two kinds: open field and greenhouse. Open field cultivation is limited by season and is generally carried out in autumn and winter. It is not suitable to water too much in the seedling stage to prevent frost injury caused by too low temperature. Then when the seedlings grow to about 8 centimeters, you can properly water more to keep the soil moist. Greenhouse cultivation is generally carried out around September every year, and enough water should be poured to help seedlings survive the winter. When coriander seedlings enter the green stage, it is necessary to do a good job of ploughing and weeding. When the seedlings grow to 8 centimeters, control the temperature at about 20 degrees and do a good job of topdressing.

2. Seed treatment

No matter what kind of cultivation method it is, we should deal with the seeds of coriander before planting. Because the outer skin of coriander seeds is relatively hard, if not treated, seed germination will be inhibited and the germination rate will be reduced. So before planting, we put the seeds in the bag, then spread them flat on the flat ground, rub the seed coat, and it is best to divide the seeds into two halves, which can effectively improve the germination power of coriander seeds. If the temperature is low when sowing, the seeds need to be soaked in warm water for a period of time, then the seeds are removed and wrapped in a wet sand cloth, and then germinated in a warm environment. When half of the seeds are white, they can be sown.

3. Environmental management

Coriander has certain requirements on the environment in the process of growth. Although coriander does not have much demand for soil, the soil with rich humus and sufficient fertility is more suitable for the growth of coriander. The demand for temperature of coriander is different in each growth stage, and the temperature should be controlled at about 13-25 degrees. Like to grow in a cool environment, but also have a strong heat resistance. Then we should pay attention to the weeding work and loosen the soil properly, which can not only ensure the growth of coriander, but also improve the field permeability and create a good growth environment for coriander.

4. Watering and fertilization

The drought tolerance of parsley is relatively poor, so we should keep the soil moist during the planting process. When the soil whitens and cracks, it should be watered in time, usually about once a week, but it should also be reasonably controlled according to the soil and weather. Drip irrigation is mainly used when watering, not too much watering, to prevent the production of stagnant water, affecting the growth of coriander. We should apply sufficient base fertilizer before planting, and the base fertilizer is mainly rotten farm manure. If the base fertilizer is sufficient, there is generally no need to topdressing during its growth period. However, if the growth of parsley is weak and its soil fertility is insufficient, then it is also necessary to fertilize properly.

The above is a brief introduction of coriander planting technology, when we plant, we also need to do a good job in the prevention and control of diseases and insect pests. Avoid diseases and insect pests to harm the growth of coriander, reduce the yield and affect the planting efficiency. That's all for today's introduction. This article is for reference only.
