Small arch shed seedling raising is to use plastic arch shed as protective cover for seedling raising. The main advantages of small arch shed seedling raising are: low seedling raising cost; The lighting conditions in the arch shed are good, and the temperature difference between day and night is large, which is conducive to cultivating strong seedlings. The main disadvantages of small arch shed seedling raising are: poor heat preservation ability, long seedling raising time in low temperature period, late seedling raising period and poor early-maturing cultivation effect; The temperature and humidity distribution in the seedbed is uneven, and the growth uniformity of pepper seedlings in the seedbed is poor.

In general, small arch shed is used for seedling raising alone, and it is often used in combination with other seedling raising methods. Common ones are:

(1) electric hotbed cultivates small seedlings, and small arch shed cultivates large seedlings.

(2) "greenhouse+small arch shed" seedling raising.

(3) "Plastic shed+small arch shed" seedling raising.
