Perilla frutescens is usually planted by sowing. Sowing dates are selected in spring, March in the south and mid-late April in the north. Do a good job of land preparation first, and you can choose the way of drilling or hole sowing. Trenching can be used for drilling, with a row spacing of 60 cm and a depth of 2-3 cm. After sowing, the seeds are evenly scattered in the ditch. After sowing, the hole sowing can keep the row spacing of 45 cm and the plant spacing of 25-30 cm.
Growth habit
Perilla frutescens has a well-developed root system, the taproot penetrates into the soil 30cm, but most of the roots are distributed in the 2- 18cm soil layer, and the root system is 40-50cm wide. The flowering period of the branch is basically the same as that of the main stem inflorescence. In the same inflorescence, the flowers at the top of 1/3 usually bloom first, and then bloom in turn after 2-3 days. It takes about 20 days from germination to flowering, and about 12 days from opening to withering.
In northern China and Zhejiang, the seeds are usually sown in early April, planted in mid-April, transplanted in mid-May, budding in late August, flowering and fruiting in mid-September, and seeds mature in mid-June. The whole growth period is about 190 days. ?
