Thumb watermelon can be divided into two planting modes: open field planting and greenhouse planting. Planting in open field can be done in spring and summer, and planting in greenhouse can be done in all seasons. The most suitable temperature for thumb watermelon growth is 16 to 30 degrees. Too high temperature will affect the growth of thumb watermelon, which will lead to low fruit setting rate in severe cases. Watermelon with thumb likes fertile land, which requires loose and moist soil, and sufficient water and fertilizer should be ensured in the growth stage to increase production.
When the thumb watermelon seedlings grow to 5-7 leaves, it is necessary to set up a frame to draw vines. The growth of thumb watermelon seedlings is slow in the early stage. If the flowering and fruiting occurs below 15 nodes, the fruits below 15 nodes need to be manually removed to ensure the later growth. Thumb watermelon is very easy to manage during the growing period, mainly by pruning and removing the yellow branches and leaves in time.
The rest of the skills
Watermelon with thumb has a high demand for sunshine, so it should be exposed to sunlight as much as possible, and it is not easy to plant in fields where trees affect sunshine. When planting thumb watermelon seedlings, water them thoroughly. Watermelon with thumb belongs to shallow root vegetables, and irrigation methods include mother irrigation and shallow irrigation. When it grows to 15, topdressing should be done once every ten days, and topdressing should be done with 4 kilograms of water per mu during irrigation.
The ripening period of Thumb Watermelon is about 3 months, and 60 days after sowing is the picking period, so it should be harvested in time, once every 3 ~ 4 days. Timely harvesting can ensure the normal growth of other fruits, thus greatly improving the yield per mu.
