Embodiment 1
[0038] Embodiment one: 'Huangjing' watermelon seed propagation method
[0039] (1) The method of promoting early breeding in local greenhouses of the male and female original species of 'Huangjing':
[0040] In the regions of Jiangsu, Zhejiang, Shanghai and Anhui, from February 5th to February 20th every year, the male and female breeder seeds of 'Huang Jing' (selected by the breeders of Shanghai Academy of Agricultural Sciences) were raised in hotbeds. The seedling substrate is: peat soil: paddy soil: refined organic fertilizer = 3:2:1 mixed substrate. When the seedlings are about 25 days old, transplant the seedlings into large and medium sheds (6-meter standard span type, 8-meter standard span type, linkage steel frame greenhouses) or glass greenhouses equipped with insect-proof isolation nets. Spread 225kg / hm on the field before planting 2 Lion horse brand compound fertilizer (N:P:K=15%:15%:15%)+225kg / hm 2 Potassium sulfate is used as base fertilizer after one-time plow...
