Embodiment 1
[0030] Embodiment 1 A kind of method of soilless cultivation watermelon
[0031] Step 1. Facility Construction
[0032] The greenhouse is a galvanized pipe arched plastic greenhouse with a width of 6.5m x a length of 30m. The middle height of the shed is 2.6m, and the shoulder height of both sides is 1.5m. An insect-proof net with a diameter of 0.05mm is installed at the inflection point from the foot of the shed to the shoulder height, and the outer side of the shed is installed with plastic. Film insulation.
[0033] Step 2. Build a soilless planting tank
[0034] There are 8 planting troughs vertically in the greenhouse, and 80cm wide working channels are set longitudinally at both ends and in the middle of the greenhouse. Each planting trough is 0.5m wide and 20cm deep. Fill the planter to the full;
[0035] The percolation layer is formed by mixing seaweed, river sand, and cinder in a mass ratio of 10:5:3; the particle size of the river sand is 0.2-0.5mm, and the parti...
