Fourth, planting:
1, To plant treated seedlings according to the size of grading were planted in different hole tray, planting depth of 0.5-0.8cm, in order not to bury the leaf sheaths, watering seedlings do not fall over as a standard.
2、After planted, spray the seedlings and topsoil with 1000 times of internal fungicide, and the standard is that the humidity is not more than 30% below the surface.
3、If the light in the greenhouse exceeds 4000LUX when planting, it is necessary to temporarily add a shade net in the greenhouse to ensure that the light does not exceed 2000LUX within 7 days of planting.
Fifth, Management:
1, Within 7-10 days after transplanted, Pls pay special attention to humidity and light, when the topsoil begins to whiten when the need to replenish water, replenish water as much as possible with spray equipment to ensure that the foliage humidity, do not make the plant withered as a matter of principle, sunny days is generally 1-2 times, more than 2:00 p.m. generally do not replenish the water, so that its foliage does not take water overnight; light control in 2000LUX.
2, The seedlings will be relatively stable after above 7-10 days, some plants began to grow root primordia, this time can be appropriate to give more water, more light. You can pour some root water in small amount, the humidity is 50% below the topsoil; the light is strengthened to 3500LUX.
3, about 15 days after transplanted, you can start applying thin fertilizer, the first time using 2500 times the nitrogen fertilizer spray leaves, the second time you can use 1,000-1,500 times the liquid fertilizer poured roots, fertilization principle of thin fertilizer, light gradually strengthened to 5,000LUX; when the seedling’s root system grows to the bottom of the hole plate when you can begin to water thoroughly, and then use the dry and wet moisture management way.
4, When young plants roots wrapped all the hole in tray, you may moved plugs plant into a large pot or for selling plugs plants. But before packaging, Pls pay attention to water control.
5,the optimal temperature for the entire planting process is 22-28 degrees, the lowest not lower than 18 degrees, the highest not higher than 35 degrees.
