Unmasking the seedlings to enhance the resistance of the rapeseed meal. The seedlings from the seeding stage to the growing seedlings in the early spring are fully covered with mulching. In 3 to 5 days before transplanting, the mulching film can be uncovered, which can effectively adapt the seedlings to the external climate and improve the quality. Seedling resistance.
The city’s agricultural department reminded all localities to take advantage of the early spring warming conditions in this spring to timely plant cabbage, leeks, early cane vegetables and edible fungus, and expand the production of sprouts and edible fungi.
Grasping the field management is currently in the middle of the growing and harvesting of bulk vegetables in the open field. In case of low temperatures, rain, snow, and freezing weather, some leafy vegetables will grow slowly and cause local disasters. Water should be drained and drained to prevent root suffocation from dying; prevention of gray mold and sclerotinia of leafy vegetables before temperature rises and humidity increases;
Promotion of facilities for the production of greenhouses, greenhouses and other facilities provide favorable conditions for the production of winter and spring leafy vegetables. It is necessary to actively promote the use of concentrated seedling raising techniques to quickly plant some leafy Chinese cabbage, lettuce, spinach, lettuce, coriander, sprouts and other leafy vegetables. Supplementary sources.
Increase the temperature and humidity to reinforce the shed body so as to avoid pressure collapse; take a small shed in the shed to cover with a small arch awning and double film; in the evening, increase the shed apron or cover straw and other insulation, if necessary, place the stove in the shed, add Shop heating lines and other measures to increase the temperature, set the light source to supplement the light to ensure that the seedlings survive and normal growth; in the nursery greenhouses placed quicklime, ash and other moisture absorption; daytime scrape off the film inside the shed, flip small arches and other films to reduce the shed Humidity; in the sunny midday open doors, open the end of the membrane ventilation and dehumidification.
Fluorine-Containing Benzoic Acid
