NOVELTY - Substrate cultivation of organic pepper involves taking 40 wt.% vermicompost, 30 wt.% mushroom slag, 20 wt.% straw and 10 wt.% perlite, sealing in plastic bag, adding distilled water, fermenting at 30 degrees C for 30 days to obtain substrate, selecting high-quality organic pepper seed, drying for 2-3 days, germinating at 25-30 degrees C for 3-4 days, plugging seedlings into 72-hole plate, sprinkling substrate at 25-40 m3/667 m2 after 15 days, controlling temperature at 18-20 degrees C at daytime and 13-15 degrees C at nighttime 4-6 days before transplanting seedlings and adjusting moisture content of substrate at 80%.    USE - Method for substrate cultivating organic pepper (claimed).    ADVANTAGE - The method has good quality of organic pepper, and has high yield, food safety and economic benefit-cost ratio.    DETAILED DESCRIPTION - Substrate cultivation of organic pepper comprises taking 40 wt.% vermicompost, 30 wt.% mushroom slag, 20 wt.% straw and 10 wt.% perlite, sealing in plastic bag, adding distilled water, fermenting at 30 degrees C for 30 days to obtain substrate, selecting high-quality organic pepper seed, drying for 2-3 days, soaking in 55 degrees C warm water for 10-15 minutes, soaking in 30 degrees C warm water for 7-8 hours, germinating at 25-30 degrees C for 3-4 days, sowing, plugging seedlings into 72-hole plate with 150 g Capsicum longum and 120 g Capsicum annuum per acre, irrigating, sprinkling substrate at 25-40 m3/667 m2 after 15 days, controlling temperature at 23-25 degrees C at daytime and 15-17 degrees C at nighttime, controlling temperature at 18-20 degrees C at daytime and 10-15 degrees C at nighttime after leaf tip comes out, controlling temperature at 25 degrees C at daytime and 17-20 degrees C at nighttime after leaves comes out, controlling temperature at 18-20 degrees C at daytime and 13-15 degrees C at nighttime 4-6 days before transplanting seedlings, harvesting, UV sterilizing, adjusting moisture content of substrate at 80% and performing pest control.
