Preparation for planting: take the substrate with good drainage and air permeability as the cultivation substrate (the ratio of pond mud: domestic peat: 1:2 or the ratio of pond mud: domestic peat: Chinese fir sawdust: 1: 1.5:2), stir the substrate with chlorothalonil solution 1000 times before transplanting, and mix the substrate with chlorothalonil solution. The amount of peat in a 9- 12cm pot is about 200-300 ml, and a pack of 300 liters of imported peat can hold about 1500- 1000 cups.
Seedlings on pots: Reuse old pots must be soaked in 1000 times potassium permanganate for more than half an hour, then washed with clear water and dried for later use. The new pot can be used directly. Generally, small flowerpots (14cm plastic cups) should be used for planting. When planting, a suitable substrate should be placed at the bottom of the cup, and then the screened seedlings should be moved into the cup. The planting depth of seedlings can be appropriate, and the flat planting base should be slightly planted, 1 plant/pot; The elasticity of the substrate is moderate until the cup is 9 minutes full. Gently shake the soil in the basin and pour the roots until it is semi-permeable.
Lighting management:
Sin Nui Hung vines like warm and humid semi-cloudy environment, so direct sunlight is forbidden in summer, otherwise the leaves will be burned. It is more appropriate to control the illumination around 15000 Lx. If you plant in a simple shed, you can spray air and water on the ground in summer morning (about 10: 00) to increase the air humidity and reduce the leaf surface temperature. Try to keep a ventilated, warm and semi-cool environment. There is too much shade in the shed in summer, and the light is lower than 15000 Lx. Leaves and petioles of plants are drooping, not erect and easy to grow. With the decrease of temperature in winter and early spring, the light can be gradually increased and controlled at 20000-30000 Lx. In short, when the temperature is high, the light is lower, and when the temperature is low, the light is stronger within the allowable range. If you plant in a simple shed, you only plant seedlings for 1-2 months, and the roof of the shed should be covered with film in summer, otherwise it will be easy to get sick in rainy days, leading to leaf rot and plant death.
