The watermelon is so thin and delicate that it is popular. Also, because of the high economic efficiency of the watermelons, many of them started growing them. But the watermelon is a new type, with its own growth characteristics compared to those of the average watermelon, and today's novel shows you how to cultivate the fine watermelon:
Precious watermelon cultivation techniques:
1. Selection of quality varieties
There's not much watermelon in the world. It's mainly anhui. The ferocious elves (skin and yellow) and the treasures (skin and red) produced by the smelter plant company limited。
There are also japanese-made early-spring red jade and taiwan-made phenomenons, which, in terms of the economic nature of the variety, do not differ from imports, but the price of imported seeds is several times higher than that of domestic seeds。
2. Distinction of planting time
Small watermelon can grow more than three seasons a year because of its short birth. In view of the low yields of small watermelons, protected areas are often used for early and fall-late cultivation in order to achieve higher economic benefits. Specific planting seasons can be based on local hot and hot resources and conservation facilities. For example, multi-layered planting methods in solar greenhouses in xinbei and shandong could be planted in late december, in early february and picked up in mid-april, while the plastic shed would be planted in late january to early february, in late february to early march and on the market in early may. In the south of the river, shed cultivation was available for planting in mid-february, with values set in mid-march and harvest in mid-may. Autumn post-plantation can be planted in mid-july, with planting scheduled in early august and on the market around national day and mid-autumn festival。
3. Cultivation
Nutritional seedlings should not be less than 8 cm in diameter. Nutrient soil is to be used by composted capacity to achieve functional enrichment and water-conservation standards. Seeds are to be dried up before planting. Small watermelon seeds are smaller, usually weighing 30-40 grams, and skin impregnation is not appropriate for long periods, usually two hours. Before seeding, nutrient-filled soil is poured through the bottom, choosing to sow in the clear. Early ripening requires instant respiration. When most seeds are soiled, the membrane should be cooled and maintained at around 25°c during the day and around 18°c at night in order to avoid the emergence of high seedlings. When the first leaf spreads, it should be properly warmed to enhance growth. A 5-7-day run-off to prepare for planting, usually 30-35 days. Autumn-lated planting, during which the seedling season is high, should keep the sun warm. Seeds are growing fast, seedlings are growing fast, age is inappropriate, usually around 10 days。
Four
The plots to be planted should be those with low levels of groundwater, easy discharge, soft soil and no melon crops for more than three years. The application is based on the application of base weights, but only 70 per cent of the average watermelon is applied, usually at a depth of 70 per cent of the watermelon before winter, about 2,000 kg of consumable organic fertilizer per acre, 25 kg of calcium phosphate, then 30-40 kg of compound fertilizer per acre. When planted in the early spring, the soil temperature is fixed at 15°c or above, at 12°c or above, depending on the weather. In the summer, planting takes place at dusk, and the values are set so that the roots are avoided。
(b) a percre of 1,500 - 1800 centimetres per acre, with a percubation of 80 centimetres wide and a percubation of 120 - 150 centimetres wide, standing or climbing in one row. The climbing plant is 200-220 cm wide, with a distance of 35-40 cm and a whole branch of three chickens, with 700-750 units per acre, and 500-550 units per acre, if it is 60 cm。
