In view of the influence of fog weather on field crops, there are several remedial measures :(1) timely soil loosening and soil cultivation between crops' roots will increase the air permeability of soil between ridges, protect the roots and raise the soil temperature.Through this simple tillage method, the ability of crops to improve root activity after foggy weather, improve the resistance of plants to fog-induced temperature drop and disease resistance.(2) Timely application of fertilizer for crops.To improve the lack of crop nutrition due to foggy weather by supplementing fertilizer.Replenish energy and use growing lights to increase the photosynthetic capacity of crops after sunny days.(3) Take physical measures to slow down the temperature decrease.If conditions permit, straw can be evenly covered between ridges in fragile fields, which can effectively improve ground temperature and protect plants.Use some smoked goods mulch if necessary to increase cold protection.(4) Cut off dead branches and leaves from crops.Cut the stem leaf of withered yellow in time, lest produce plant organization mildew pathological change, induce disease and insect pest
We found that many vegetable farmers have hung reflective film in their sheds.Admittedly, this reflects light back to the vegetable plants, but it is more than worth the loss by affecting the temperature of the shed.Why do you say that?The insulation effect of the greenhouse is good, in addition to the small heat dissipation area, a very important point is that the walls on both sides and the back wall absorb and store heat under the light during the day, and emit it at night to maintain the night temperature.
Not only that, led plant
Grow Lamp can also achieve the control of plant growth rate,
Plant Lamp can make the flower plant flowering period extension, so that cash crops can not be restricted by the season, accelerate the results.For example, plants can photosynthesize for up to 16 hours a day, but natural light is very limited, making plants grow slowly.If LED lights are used to continuously supplement the light for plants, and laser plant lights are used instead of natural light, the customers of plant lights can shorten the maturity period of vegetables by one third and realize the increase in yield. Vegetables mature in 15 days can be harvested in only 5 days. This is a typical example of using laser plant lights to promote the growth of plants.
