Cultivation method for premature small watermelon

Abstract

The invention belongs to the technical field of agriculture, and discloses a cultivation method for premature small watermelon. The method comprises the following steps of: (1) grafting and raising seedlings: the sowing time of stocks is the first ten days and the middle ten days of December, and scions are sowed in 7 to 12 days later than the stocks; (2) planting grafted seedlings, and performing heat insulation and temperature rise by adopting four-layer coverage of a big shed, a medium shed, a small shed, a mulching film and an electric heating wire; (3) controlling the temperature; (4) pruning with a double-vine or three-vine pruning method; (5) performing artificial pollination and leaving fruits: performing artificial pollination when the second female flower of the main vine and the first female flower of the side vine come out; and (6) harvesting. The harvesting time of the premature small watermelon cultivated by using the method is advanced to the middle ten days and the last ten days of April and advanced by 20 to 30 days compared with the conventional greenhouse cultivated watermelon, and the harvesting time is kept away from the plum rain season of the southern district, so that high yield and stable yield are ensured. Not only the market demand is met, but also the yield and the economic benefit are greatly improved.
