Seed production and yield increasing method for thick-skin muskmelons in protected area

The invention discloses a seed production and yield increasing method for thick-skin muskmelons in a protected area. The problems of low double-melon rate, malformation of double melons or one melon, irregular fruit setting and the like caused by the fact that fruits at adjacent pollination node positions cannot synchronously and normally develop after pollination and fertilization are solved. The seed production and yield increasing method comprises the following steps that firstly, according to the characteristics that main vines of thick-skin muskmelons continuously generate sub-vines, and the sub-vines are used for fruiting flowers, pollinating and keeping the melons; according to the method, small topping pruning, boron fertilizer spraying on leaf surfaces, artificial cross pollination and combined use of forchlorfenuron are adopted, after artificial pollination and fertilization, young fruits at adjacent leaf joint positions are selected and reserved, forchlorfenuron with proper concentration is selecti
