Perilla frutescens cultivation is quite simple, and it is an entry-level vegetable. Even beginners can grow Perilla frutescens well according to the cultivation method. We plant a small piece every year in our park, which basically needs no management, grows well and is convenient to eat. The following are several cultivation links that should be paid attention to in perilla planting. First, the suitable environmental conditions for the growth of perilla frutescens
Perilla frutescens likes warm and humid environmental conditions, and it can grow at 1-35℃, but it grows better in the slightly cool climate of 18-28℃; I like sunshine, but it is easy to grow in vain when the light is insufficient, and the taste is not strong; It is drought-tolerant, barren but not waterlogging-tolerant, and the requirements for soil are not strict. Perillae can be planted in fields, in front of houses and behind houses, but the land with high terrain should be selected to facilitate drainage in rainy season. Second, the planting method of perilla frutescens
1. Planting time: you can sow directly or transplant after raising seedlings. The climate in the south is warm, so direct sowing can be done in March-April; The climate in the north is cold, and most of the seedlings are raised indoors, and then transplanted to the open field in April-May.
2. Seedling raising method: Perilla frutescens seedlings are still quite large, so it is best to choose a nutrient bowl with a diameter of 8-1 cm for seedling raising and special nutrient soil for seedling raising. The germination rate of perilla seeds is not very high. Put 5 or 6 seeds in each nutrition pot to ensure that 2-3 seedlings can grow in each nutrition pot. After sowing, cover the soil with 1.5cm, and finally cover with plastic film or straw for heat preservation and moisture retention, which is beneficial to seedling emergence.
3. Transplanting: Perilla frutescens seedlings are not very strict in size, and plants can be transplanted when they grow to 4-8 leaves. Before transplanting in the field, you should first apply foot fertilizer, level the soil, and make a high border with a width of 1.3 meters. The border ditch is 4 cm wide and 15-2 cm deep, and the drainage ditch is opened around it.
Because each cultivation hole is planted with a nutrition pot (2-3 plants) during transplanting, the row spacing between plants is larger than that of single plant transplanting, with the row spacing of 4cm and the row spacing of 3cm. When transplanting, ensure that the soil lump is complete without damaging the root system, which can better slow down the seedlings. After planting, pour enough planting water.
4. Water and fertilizer management: after transplanting the seedlings slowly, combine weeding, intertillage and loosen the soil for 1-2 times, and topdressing 1 kilograms of decomposed human excrement and urine per mu; Before the plants are closed, 2 kilograms of decomposed human excrement and urine should be applied to each mu of land. Try not to apply chemical fertilizer when planting perilla, otherwise the smell and taste will be affected, and water less, without drought or watering.
5. Pests and diseases management: There are few pests and diseases in perilla frutescens planting, which are mainly harmed by Pieris rapae in summer and autumn. If the area is not large, it is best to catch the insects manually; When the planting area is large, it needs to be sprayed with chemicals, and the biological agent Bacillus thuringiensis can be sprayed with good insecticidal effect.
6. Harvest: Perilla frutescens mainly harvests tender stems and leaves, which can be harvested many times.
