Detailed Key Points of Japanese Sweet Treasure Melon Cultivation Techniques
First of all, select a suitable plot; sandy loam or sandy soil with a loose texture is best. Apply sufficient base fertilizer, prepare the land, and make beds. Adopt the open-field direct seeding method. Before sowing, water thoroughly to ensure sufficient soil moisture, and germinate the seeds. Pay attention to disease prevention and control in the middle and late growth stages.
1. Select a suitable plot
For planting melons, sandy loam or sandy soil with a loose texture is best.
The previous crop was a winter fallow field; this kind of plot warms up easily in spring, the plants grow quickly, and the melon quality is good.
2. Apply sufficient base fertilizer, prepare the land, and make beds
Melons rely mainly on base fertilizer; apply 7000 kg of decomposed chicken manure or barnyard manure, 50 kg of diammonium phosphate, 50 kg of potassium sulfate, and 10 kg of urea per mu, so as to meet the nutrient requirements for the whole growth period. Then plow and harrow the land, and after the land is leveled, dig the beds.
3. Sowing
Adopt the open-field direct seeding method. Before sowing, water thoroughly to ensure sufficient soil moisture, and germinate the seeds; after the seeds show white sprouts, open furrows on the prepared high beds and sow, planting two rows per bed, with a row spacing of 60 cm and a plant spacing of 30 cm, sowing 2-3 seeds per hole, covering with 3-4 cm of soil, and covering with film after sowing.
4. Management
The Japanese Sweet Treasure melon is a variety that bears fruit on secondary vines. After emergence, promptly break the film to release the seedlings, and at the same time support small arched sheds for protection. Transplant when there are 3-4 leaves, leaving 2000-2200 plants per mu. As the temperature rises, gradually ventilate and roll up the film. At 5-6 leaves, remove the arched shed film but keep the ground film, and pinch off the growing tip of the main vine to promote the growth of primary vines. Keep 2 robust primary vines per plant, pinch off the growing tips of the primary vines at about 15 leaves, and select secondary vines at nodes 3-8 to bear fruit, with 2-3 fruits per plant. After the secondary vines set fruit, leave 2 leaves and pinch off the growing tip. To ensure melon quality, no watering is arranged throughout the whole growth period, but in case of special drought, watering is also needed to cool the plants.
In the middle and late growth stages, pay attention to disease prevention and control. After diseased leaves are found, spray fungicide and 0.3% potassium dihydrogen phosphate solution on the leaves, once every 7-10 days, spraying 2-3 times in succession, so as to control the disease, help the melons swell, and increase the sugar content. After fruit set, promptly arrange the vines and position the fruits. During the fruit development period, turn the fruits frequently so that they color well. Near maturity, place straw or sandy soil under the fruits to prevent rotting or insect damage.
