How to grow perilla? How to prevent perilla diseases and insect pests?

Perilla is a very common plant in our life, often appears on our table, can be used for seasoning or can be eaten raw and boiled soup, at the same time, it can also be extracted into medicine and cosmetics, high economic value, then how to grow perilla? How to prevent perilla diseases and insect pests?

First, the planting method of perilla

1. Land selection and preparation

Perilla has a strong ability to adapt to the environment, and does not pick out the quality of the land, as long as it can be drained well and sunny, it will be good. Of course, if the soil is more fertile and grows better, the land can also be flattened properly during soil preparation, and then ridged and ditched, which is conducive to drainage.

two。 Irrigation and fertilization

When sowing, it is best to choose after rain or when it is about to rain. If it does not rain for several days after sowing, then artificial irrigation will be carried out. Of course, if it rains for several days in a row, drainage will be carried out. Too humid environment is not very suitable for perilla growth, and the growth period of perilla is relatively short, so concentrate on fertilization once at the beginning of sowing. The time for the second fertilization is to wait for perilla to grow to about 15-20cm, but you must pay special attention to fertilizing, do not sprinkle fertilizer on the leaves.

3. Sowing mode

Perilla can be planted in two ways, one is to sow seeds directly on the whole land, and the other is to sow the seeds on a piece of land first, and then transplant it after it grows seedlings.

2. pest control of Perilla frutescens

1. Disease

In the process of breeding, perilla will also have some diseases, such as powdery mildew, which should be sprayed with Xiansheng and Shigao, which can effectively prevent powdery mildew. Spot blight often occurs during perilla harvest, generally because the plant density is too small, the sun is insufficient, and the land is too wet, so we must pay attention to density and drainage when planting. Once the disease occurs, use Dyson Zinc or Bodol spray.

two。 Insect pest

The two most common pests of perilla are red spiders and Spodoptera litura. Once they eat perilla leaves, they only need to use the most common trichlorfon to get rid of them. For red spiders, they should be sprayed with dimethoate milk.

The above is the introduction of perilla planting methods and pest prevention measures. Although perilla is relatively easy to grow and easy to survive, we should also pay attention to planting methods and field management, otherwise it is difficult to achieve the expected yield.
