See the light slowly to avoid sudden flash after the seedlings are in a shade. Use 1 to 3 grasshoppers to open a method, so that the vegetables will gradually see the light and avoid the seedlings hitting the seedlings. So repeated several times or a few days, the number of uncovered oysters from a little to as much as normal until the growth of vegetables.
Stilts using roller shutters do not pull the grasshoppers all at once, they are rolled up slightly and then gradually added. After entering the normal management, as early as possible in the temperature permit to expose and cover the grass cover, exposing the grass cover time should be to uncover the grass after the temperature is not obvious decline in the shed is appropriate, cover grass time should be based on the season and the indoor temperature It is better to cover the grass in the shed when the temperature drops to 17°C.
In order to suffer from frost damage, it is necessary to promptly remediate the removal of dead branches, artificially spray water, conduct management with low temperature and less light, gradually increase lighting and increase the temperature in the shed. For the plants with weaker growth or more results, timely harvesting and appropriate sparse fruit thinning are needed to reduce nutrient consumption. At the same time foliar spray fertilizer, nutritional supplements, the general foliar can be sprayed with 0.3% potassium dihydrogen phosphate plus 0.3% calcium nitrate, 1% glucose solution.
Strengthen moisture control and disease prevention Continuous low-temperature rainfall weather, shed air humidity, easy to induce disease, should be ventilated and ventilated in a short time at noon to control the occurrence of diseases, with special attention to the indoor temperature at 15 °C ~ 25 °C, to ensure relative humidity in the air 90% or less, to avoid the rapid invasion of pathogens, the incidence of smoke agents can be used, dust control.
