Transplanting should be done immediately following the last frost date when the weather begins to warm. In hotter climates, this will usually be around March or April. If you live in a location that experiences lasting winter temperatures, you might have to wait until closer to summer to plant viable young peppers. Green peppers can be grown basically year-round in arid regions where the environment is hot and temperate. Just make sure your plants get enough water if you're growing them in a place that's hot with dry conditions.  Most people should plan on starting their seedlings indoors around late January or early February and transplanting them after around 10 weeks.  Keep row covers on your green pepper plants at night after they’ve been transplanted outside to help them retain heat. Set aside a corner of your garden with plenty of room to continue growing the green peppers. The site you choose should have soil that is well-drained, rich and dark. Try to choose a location that receives direct sunlight, and make sure you plant the peppers far enough away from other hearty fruits and vegetables to avoid competition for nutrients.  Green peppers do best if they’re grown in places with temperatures around 70 degrees or hotter.  Don’t plant harvesting vegetables like green peppers near leafy plants that may be eaten by rabbits and other foraging animals. Use a shovel or hand trowel to dig holes roughly 6-8 inches deep and 10-12 inches wide. Aerate the soil around the holes thoroughly. Plant the green pepper seedlings in the holes and refill them loosely. Green peppers should be planted approximately 18-24 in (46-60 cm) apart to have room to grow without overtaking one another. Work a little organic fertilizer, such as blood meal or organic compost, into the soil to keep the pepper plants fed. Don’t use too much: about a teaspoon worth will do the trick. Green peppers take most of their sustenance from the soil they grow in, so overfertilizing can actually leach nutrients from the plants and in severe cases...

TL;DR in Chinese:
等到当季合适的时间。 在花园里找一片开阔、阳光充足的地方。 挖一些足够大的洞，把辣椒种进去。 给土壤施点肥料。 天气寒冷时，用棚布把植株盖好。
