The temperature in the shed rises rapidly(104 cell seed starting trays). More rainy days, the air humidity in the greenhouse is always high, it is easy to cause disease. First of all, we must do a good job of dehumidification in greenhouses. Secondly, we must do a good job in spraying prevention work on a regular basis. Generally, it should be sprayed once every 7 to 10 days(plant planters pots). At the same time, it is necessary to do a good job of cleaning up the diseased leaves in the shed in time to reduce mutual infection.(large terracotta plastic plant pots manufacturers)


Since the greenhouse has been planted for a whole year, a large number of germs remain on the soil(105 cell seed starter trays), air, scaffolding and shed film in the shed, which is the source of infection of crop diseases in the shed. So do a good job of killing. Commonly used methods are: pesticide, steam, summer high temperature and other three disinfection methods, but the use of chemicals, steam for disinfection costs are high(large plastic garden pots cheap), the general farmers can use summer high temperature sterilization methods.


For 10 to 15 consecutive days(32 cell seed starter trays), the general pathogens and pests in the shed can be eliminated, but it is not effective against the Fusarium oxysporum in the soil. The most effective way to control the occurrence of crop pests in the shed is to set up an insect-proof net in the ventilation window of the greenhouse, adopting a silver-gray-proof insect-proof net, and the insect-proof net generally requires 40-60 mesh/m2 (the number of meshes is too small(15 gallon plastic container), the insect-proof effect) Not good; too many meshes, poor ventilation.)


(large terracotta plastic plant pots manufacturers)In time, the old leaves at the bottom of the crop are destroyed, the ventilation and light transmission in the shed are increased(105 cell plastic propagation tray wholesale price), and the soil and air disinfection work in the shed is also required. Accumulation over the years will cause a large outbreak of crop diseases in the shed. It needs to be controlled by chemicals or grafted seedlings(plant propagation trays). Even in the winter, when the sun comes out, the temperature inside the shed can be raised to above 40°C within 1h. 


If pests occur in crops in the shed, they should be treated in time(200 cell seed starter trays), but low-toxic and low-residue pesticides must be used. For pests and some underground pests entering the shed, it is best to use poison baits and physical methods to induce traps. Due to long-term coverage and lack of rainwater leaching in the greenhouse soil, soil salt return often occurs, causing excessive accumulation of soil salinity in the tillage layer(terracotta plastic plant pots), which affects the growth of crops in the shed, which will cause the crops in the shed to die.


The main measures to prevent excessive accumulation of soil salinity in the greenhouse are: when the crops are not planted in summer(seedling trays wholesale), the roof film of the greenhouse should be removed, so that the soil in the shed is freely washed by rain. In the case of not peeling off the top film of the greenhouse, in the gaps of crops planted in the season, fresh water should be used to wash the soil salt returned from the shed(3 gal plastic nursery pots). To avoid the use of chemical fertilizers alone, try to apply more organic fertilizers and less fertilizer.


(large terracotta plastic plant pots manufacturers)The daily variation of temperature in the greenhouse is the same as that of the open field, but the temperature difference between day and night is very large(plant start trays wholesale). If the shed film is closed during the daytime, it is generally 20°C higher than the outside of the shed, even up to 30°C. The specific method is that in the high temperature season in summer(plant cell trays), the soil in the greenhouse is filled with water, and the operators enter and leave the greenhouse to develop the habit of closing the door.
