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...

Problems solved by technology

[0003] However, small watermelon seeds are small and expensive, and the growth potential of the seedlings is weak. Each growth period has strict requirements on temperature, light, water, and fertilizer. The weight of a single fruit is only 1-2kg. Therefore, it is a large-scale and standardized production to increase the yield and quality and to market early. and the basis for development

However, there are many problems in the current production, such as high investment in early-maturing cultivation, natural conditions in early spring (low temperature, continuous rain, etc.) are not conducive to the normal growth of watermelon, the current cultivation method is late in the market, the yield in the early stage is not ideal, and the rainy season coincides with the later period, etc. , there is still a lot of room for improvement in planting efficiency

[0004] At present, the early-maturing cultivation of small watermelons adopts the greenhouse + small shed covering method, and the yield and output value have increased to a certain extent compared with open field cultivation. The market period is mid-to-late May. The cultivation environment is high temperature and high humidity during the fruiting period, and soil-borne diseases occur seriously. During the rainy season, large losses are often caused
