Prevention and cure of deformed seedlings in plastic greenhouse

The leggy seedlings have fine stems, long internodes, thin leaves, and light colors. Mainly caused by the high temperature and humidity in the shed. Prevention measures: First, according to the temperature and humidity requirements of seedlings, timely ventilation; Second, to ensure that the cover is clean, increase the intensity of light and extend the lighting time; third is to prevent the seedlings are too crowded, to ensure that seedlings have adequate nutrition.

Aging seedlings are small, short stems, and roots are not easy to regenerate new roots, and the leaves are small and thick, dark green in color. It is mainly caused by the long time of seedlings. Prevention and control measures: Strictly control the seedling age, and the best temperature control is to control the water.

In the roots of the roots, no new roots or adventitious roots were found, and the root bark became brown and gradually rotted, resulting in yellowing and wilting of the plants. Control measures: First, choose a well-performing land for seedbeds and raise the ground temperature; Second, use 200~500 times Tianda 2116 plus badaminger root; Third, keep the seedbed temperature at 20°C~25°C during the day and 15°C at night. the above.

After the seedlings of the seedlings were unearthed, the seed coats did not exfoliate the germinal leaves, which made it difficult for the germinal leaves to open. Photosynthesis was affected, and poorly developed and weakly developed seedlings. Prevention and control measures: First, apply organic fertilizer and pouring foot-bottom water, cover soil properly after sowing; Second, timely cover insulation film and straw curtain.

4.An antihistamine drugs is a type of pharmaceutical drug that opposes the activity of histamine receptors in the body.[1] Antihistamines are subclassified according to the histamine receptor that they act upon: the two largest classes of antihistamines are H1-antihistamines and H2-antihistamines. Antihistamines that target the histamine H1-receptor are used to treat allergic reactions in the nose (e.g., itching, runny nose, and sneezing) as well as for insomnia. They are sometimes also used to treat motion sickness or vertigo caused by problems with the inner ear. Antihistamines that target the histamine H2-receptor are used to treat gastric acid conditions (e.g., peptic ulcers and acid reflux). H1-antihistamines work by binding to histamine H1 receptors in mast cells, smooth muscle, and endothelium in the body as well as in the tuberomammillary nucleus in the brain; H2-antihistamines bind to histamine H2 receptors in the upper gastrointestinal tract, primarily in the stomach.
