How to plant perilla seeds

Suzi is mainly distributed in the central and southern regions of China, such as Jiangxi, Tieling, Liaoning, Taiwan, Hunan, and so on. Today, the editor would like to introduce to you how to grow perilla seeds. Let's take a look!

First, how to plant perilla seeds

The seed of Suzi is small, and the weight of 1000 seeds is only 340 g. Before sowing, the seeds are strictly selected by artificial air to remove blighted grains, broken grains and impurities. Choose flat loam and fine rake. The accumulated temperature for seed germination is 50 ~ 75 ℃, and the daily average temperature is 11.54 ~ 28.12 ℃. Generally, the seeds are sown from Qingming to Grain Rain, and the seeds are spread evenly into the ditch according to the row spacing 25cm, and the seeds are slightly suppressed by covering thin soil.

II. Harvest time of perilla

The main results are as follows: 1. the ripening of perilla seed is generally in autumn, and it is very easy to drop grains after ripening, especially in windy days and sparrows, so timely harvest is very important. early harvest is not good grain maturity, low yield and low oil content in seeds. Too late serious grain drop also caused a reduction in yield. The best harvest time is generally from late September to early October, around Cold Dew according to solar terms.

2. The stem of Perilla turns yellow, most of the leaves fall off, and the Corolla calyx tube turns yellow and shrinks as its mature biological characteristics. When harvesting, tie it into small bundles, generally speaking, five or six trees into a small bundle, stand up, so that you can dry faster. During harvest and threshing, mechanical threshing or manual threshing can be used to screen precipitation in time after threshing, and it can be stored when the water content is less than 9%.
