Cultivation method of lotus lamp in north greenhouse

Abstract

The invention relates to a cultivation method of a lotus lamp in a north greenhouse, which comprises the steps of: planting a lotus lamp plantlet in a substrate mixed by turfy soil and pearlite in the proportion of 7.5:1.5-8:1.5; irrigating the substrate by using clean water with pH value of 4.0-4.5; spraying a water solution once on the plantlet after irrigating 2-4 days, wherein 1 L of the water solution contains 0.4-0.5g of chlorothalonil and 0.3-0.4g of abamectin; controlling the temperature at 24-26 DEG C in daytime and 18-20 DEG C in night, humidity at 70-80 percent in daytime, humidity at 75-85 percent in night and illumination at 12000-18000Lux; irrigating clean water with pH of 4.0-4.5 when EC value is more than 0.25 after irrigating 7 days first time, irrigating a water solution once when the EC value is less than 0.25, wherein the 1L of the water solution contains 1.2-1.4g of peters professional 20-10-20 and 0.5-0.6g of phoxim; then irrigating0.6-0.8g / L of water solution containing KN3 once, then irrigating 1-1.2g / L of water solution containing peters professional 15-20-25, and spraying the water solution prepared by dissolving 0.4-0.5g of chlorothalonil and 0.3-0.4g of abamectin in per 1 L of the water.
