A kind of propagation method of spring cauliflower, summer lettuce and autumn zinnia

Abstract

The invention discloses a seed multiplication method of spring cauliflowers, summer lettuces and autumn zimnia elegans, and belongs to the technical field of plant breeding. Sowing and seedling raising of the spring cauliflowers are performed in mid-January; after harvesting of the spring cauliflowers is finished, hole direct sowing of the summer lettuces is performed in mid-May by accelerating germination; sowing and seedling raising of the autumn zimnia elegans are performed in late June, after harvesting of the summer lettuces is finished, planting of the autumn zimnia elegans is performed in mid-July, and harvesting of seeds begins in mid-October. The spring cauliflowers can effectively fill up the spring blank, and the summer lettuces can effectively fill up the hot season blank; the yield of the cultivation mode with three crops a year is increased by more than 40% compared with the cultivation mode with two crops a year, and therefore remarkable economical benefits are achieved; the usage amount of chemical fertilizer is reduced or no chemical fertilizer is used, disease-resistant varieties are selected, almost no pesticide is used in the whole growth period, biodiversity is improved, and pest damage is greatly reduced; straw of the zimnia elegans is smashed and returned to be field for maintaining the soil moisture content, soil physical and chemical properties can be effectively improved, soil fertility can be improved for production of the next crop of cabbage vegetables, and therefore ecological benefits are achieved.
