Matters needing attention in planting coriander

Coriander is a very special vegetable. Experimental investigation shows that at least 7 people in the world hate cilantro very much, and the editor is one of them. People who don't like cilantro have a specific gene called OR6A2, which is a gene that tests the special flavor of parsley, so they don't like parsley not because of food regulation, but because of genetic problems! What the editor brought today is what to pay attention to when growing coriander. Let's take a look at it.

1. Reproductive characteristics

When planting cilantro, be sure to prepare for the next wave of cilantro planting, the main way of reproduction is to sow seeds. Coriander is generally suitable to be planted in the south, so it can be planted in all parts of the south, and there are also some areas with suitable temperatures in the north. Before planting coriander, the first thing to do is to sow and raise seedlings. After the coriander is planted, the outer skin of the seed is rubbed off, and then the seed is placed in a basin that has been fully watered, and the seed will begin to germinate in a week or so. After germination, the seeds can be transplanted to the prepared pastoral land.

2. Temperature fertilization

Coriander growth process needs to have a suitable growth temperature, generally coriander can normal growth and development temperature of about 16-18 degrees, this temperature is the fastest time of coriander growth and development. If you plant in summer, you should pay attention to cooling the seeds. Too high temperature is bad for the growth of coriander. If the base fertilizer is sufficient, try not to topdressing, but when the base fertilizer is insufficient, you should do one extra-root topdressing about ten days before harvest, and you can spray urea twice. Then fully mature farm manure is sprayed every 15 days, and a little phosphate fertilizer can be applied to it if the seed is reserved for the next time.

3. Watering work

Before setting coriander seedlings, we should try not to water them as far as possible, because this can help to control up and down, and squat seedlings to strengthen their roots. After setting the seedling, you can start to fertilize it. First of all, apply a stable seedling water immediately after planting, and the amount of water must not submerge the seedling. Then as the seedlings grow, the water demand will increase, and the frequency of watering will gradually increase. It is usually watered in shallow water about seven times during the growth period. The interval should not exceed ten days. When watering for the fourth time, the watering interval should be shortened to once a week. To keep the soil moist, the amount of watering should be controlled before harvest, mainly in shallow water.

4. Disease control

Because of its own particularity, coriander has a strong resistance to diseases and fewer diseases occur. However, because most of the parsley is planted in the open air, and summer is also a period of high incidence of insect pests, it is necessary to pay attention to pest control in summer and autumn and spray it with agents such as methamidone salt or Caixi suspension, once a week. Although there are few diseases, we can not relax our vigilance, strengthen the management of vegetable garden, carry out disinfection, concentrate on dealing with diseased and residual branches, and reduce pathogens.

The above are some of the areas that need to be paid attention to when planting coriander, just because of its strong disease prevention ability and low incidence rate, we should not think that parsley will not have diseases. If improper management, no timely drainage and irrigation, cleaning up residual branches and other work is done well, there is still a certain probability of disease, so I hope everyone will take it seriously in the planting process.
