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.

Description

technical field

[0001] The invention belongs to the field of agriculture, and in particular relates to a small watermelon early-maturing cultivation method. Background technique

[0002] With the improvement of people's living standards, the consumption structure and diet concepts are constantly updated. People's consumption demand for watermelon is no longer based on quenching summer heat and thirst, but pursuing quality, characteristics, annualization and diversification. , The commodity is outstanding, and the listing period is as long as 8 months, which is in line with people's consumption habits, and is very popular with consumers, and the demand is increasing day by day. The huge consumption market of small watermelon has promoted the adjustment of watermelon planting structure. At the same time, small watermelon has a short growth period and is suitable for diversified cultivation. Generally, every 667m 2 The output is 2500kg~4000kg, and the market sales price can b...

Examples

Embodiment 1

[0030] The present invention will be described in further detail below in conjunction with specific examples, but this does not constitute any limitation to the present invention. Example 1 "Early mature small watermelon, summer and autumn regenerated small watermelon" cultivation mode

[0031] 1. Cropping arrangements: the first crop of early-maturing small watermelons. The rootstock sowing period is in early and mid-December, and the scion is sown 7 to 12 days later than the rootstock, and the scion is grafted when the cotyledons are flat; in early and mid-February, it is planted in four layers of greenhouse + medium shed + small shed + plastic film. Harvesting begins in mid-April and ends in early June. The second batch of small watermelons regenerated in summer and autumn. After the watermelons are harvested in early June, 2 to 3 new lateral branches at the base of the plants are selected for regeneration, and harvested after 40 to 50 days.

[0032] 2. Variety selection:...

[0054] Example 2: "Early mature small watermelon, rice" cultivation mode

[0055] 1. Stubble arrangement: adopting the watermelon + rice model in the grain area can greatly improve production efficiency. The first crop of early-ripening small watermelons. The rootstock sowing period is in early and mid-December, and the scion is sown 7-12 days later than the rootstock, and the scion is grafted when the cotyledon is flat; it is planted in early and mid-February, and harvested in mid-April to early June. The second crop of rice is raised in late May, transplanted in late June, and harvested in early and mid-November.

[0056] 2. Variety selection: Choose small-fruited watermelon varieties with early maturity, low light resistance, humidity resistance, and good quality, such as Xiaolan and Early Spring Hongyu. Rootstocks should be selected from varieties with strong disease resistance, strong stress resistance, good compatibility with scions, and little impact on watermelon qua...
