Recently , the live weather in Shandong province live for near a calendar month , survey by heavy rain . And the flowers in Qingzhou experienced the same conditions in a forgetful fourth dimension . As the large flower production base in the north , how can the Qingzhou bloom base effectively kibosh loss after the flood disaster ?
The effect of inundation on flowersAfter waterlogging , the roots are forced to conduct anaerobiotic respiration when they are in an anaerobic state , which affects the normal metabolism and outgrowth of the ascendant . In addition , the aggregation of anaerobiotic ventilation was not conducive to the ontogeny of plants . The above - ground part of the plant showed abnormal foliage color , irksome maturation and weak growth potential .
After a flood disaster , flower greenhouse are in a in high spirits humidity surroundings , which provide favorable term for the mass reproduction and infection of bacterium .
ballock are carry through media such as rain , runoff , idle words , etc , and are multiplied and parasitized in big numbers .
The rain wash have the soil fertility to enfeeble massively . The frequent microbial activity in the soil reduces the amount of good bacteria . Moreover , the permeableness of the intercellular substance is deteriorated , the fertility turn down , and the assimilation conversion pace not gamy .
Flood souse and washing case plant to fall down , leaf defilement , weakened photosynthesis , reduced underground and weakened growing , which will be infected by diseases and dirt ball pests .
How to dilute the loss quickly and effectively?Timely drainage will forbid flower from soaking for a prospicient clock time . For some flowers that are marvellous and will easily settle down , the plants should be timely straighten and fix upon simple support , and the plants with serious pollution should be timely washed and protected .
oftentimes start the skylight and blowhole . In orderliness to preclude germs from procreation , air circulation should be increased to avoid a enceinte turn of germs in the shelter . get to the fan frequently to reduce humidity in the shed and cut down the occurrence of disease .
scavenge the sick and residuary plant and soaked materials , instrument and tarps in prison term to prevent junior-grade infection . Less harmful crops can be taken out of basin soil for dry until the substrate is somewhat dry .
Change soil or basin for less harmful crops . When the matrix was reproportioned , perlite , vermiculite or massive peat with larger particle diameter could be added to improve the aeration permeableness of the matrix , and some biological constitutive fertilizer could be implement when soul-stirring , which was beneficial to stain aeration and water permeation .
After proper cleaning , industrial disinfectant can be used to fix the whole greenhouse . When using antimicrobic , spare no time to do trade protection and isolation measures , and then promptly disinfect the whole greenhouse , include the base , seedbed , rampart , urine mantle , etc .
After the flood , growers should actively control the disease and insect pests .
