Embodiment 1

[0034] (1) Fertilization for soil preparation: apply base fertilizer, deeply plow into the soil, and rake and level the furrow;

[0035] Choose paddy fields with high and dry terrain, matching ditches, convenient drainage and irrigation, and fertile soil. Mechanically plow once after the harvest of the previous crop, and apply base fertilizer before planting, 667m 2 Apply 1500kg of decomposed organic fertilizer, 100kg of vegetable cake fertilizer, 25kg of high-concentration compound fertilizer, 30kg of superphosphate, and 10kg of ammonium bicarbonate, deeply plow into the soil, rake and level the furrow, and set up two furrows in the shed. The width of the furrow is about 3.5m, and the width of the ditch is 0.5m. .

[0036] (2) Buckle shed cover film: such as figure 1 As shown, earlier lay white film 5 in the area where steel pipe greenhouses need to be set up, and cover black film 6 with a width of 0.9m between the sheds. The width of the shed is 8m, the width of the worki...

Embodiment 2

[0046] The difference between embodiment 2 and embodiment 1 is: in step (1), two furrows are set in the shed, the width of the furrow is 2.7m, and the width of the ditch is 0.5m; step (2) buckle the shed cover film: first set up the bamboo frame The area of ​​the greenhouse is covered with white film, and the black film with a width of 0.9m is covered between the sheds. The width of the shed is 6m-6.5m, the width of the working ditch between the sheds is 1.2m (including the film-pressing furrow outside the shed), the depth is 0.5m-0.6m, and the length of the shed is 70m. The shed is built with a bamboo frame, with a width of 7m and a height of 1.8m; the seedlings of Zaojia (84-24) with a seedling age of 28d to 32d are transplanted at an average rate of 667m 2 Plant 280 to 300 plants; after planting, set up a small arch shed to buckle above the furrow, and build an arch shed to buckle above the small arch shed; among them, the arch shed is built with bamboo slices, with a width...

Abstract

The invention provides a watermelon one-film four-shed early-ripe cultivation technology. The cultivation technology includes the following steps: (1) soil preparation and fertilization: applying a basic fertilizer, deeply turning soil, harrowing the soil, and constructing beds; (2) greenhouse establishment and film covering: establishing a greenhouse, wherein the establishment order of the greenhouse includes establishing a large-size arc shed and a middle-size shed 10-15 days before planting, laying dripping pipes 7 days before planting, covering the soil with plastic films, establishing an arch shed and a small-size arc shed after planting, and achieving an one-film and four-shed structure; (3) field management including temperature management, fertilization management, pruning and fruit retaining, artificial pollination, and pest and disease control; and (4) harvesting: performing marking, accurately determining the ripe period of the watermelon, and performing harvesting in batch. The cultivation technology is good in warming effect, can promote early- ripe of the watermelon, is high in the yield of the watermelon, can allow the watermelon to come into markets in advance, can improve the average sell price, and can increase economic benefits.

Description

technical field [0001] The invention relates to a crop cultivation technology, in particular to a watermelon one-film four-cover early cultivation technology with good heat preservation effect and anti-season characteristics. Background technique [0002] Watermelon ranks fourth among the world's top ten fruits and occupies an important position in the world's horticultural industry. As an important high-efficiency economic crop, watermelon plays an important role in the adjustment of planting industry structure in my country and the promotion of farmers' wealth and income. Watermelon is a crop that likes temperature, light, and water, but is afraid of humidity, requires a dry climate, and is not resistant to waterlogging. It not only grows poorly under low temperature and rainy climate conditions, but also causes serious damage from diseases and insect pests. Therefore, the requirements for its cultivation technology are very high. With the promotion of greenhouse planting...
