Heat damage When lettuce and celery sprout at high temperatures, it is difficult to soak the seed for 8 hours and then use a wet gauze to wrap it in the well or in a cold place to germinate. Or low-temperature treatment, celery is 2 °C ~ 5 °C 48 hours, lettuce is 5 °C 72 hours, can promote germination, increase germination rate. It is also possible to sprinkle some crop straw or straw on the seedbed; or to cover the seedbed with cold yarn or shade nets, or to cover shade sheds, cover old films, non-woven fabrics, bamboo curtains, curtains, etc.; or Seedlings under high crops.
Severe vegetable virus diseases occur at high temperatures and various measures should be taken: In addition to the above-mentioned nursery facilities, 10% trisodium phosphate solution can also be used to treat mustard and tomato seeds for 10 minutes and then rinse with clean water; or inoculate tomatoes with attenuated vaccines. Choose anti-virus varieties; use nylon net yarn to prevent warts; use silver-gray film to avoid warts; timely anti-mite and so on.
The rain damages the soil in summer with heavy rain, which is not conducive to seed germination and unearthing. The following measures should be taken: choose a high dry land to build a seedbed; be vulnerable to rainstorm areas should choose sandy loam seedlings; smooth drainage around the seedbed, use temporary cover to reduce heavy rain hazards; after sowing, in the event of heavy rain, seeds not found, after the rain in the seedbed Shallow cultivator to prevent soil surface compaction.
Drain the seedlings in the seedbeds and sow them, or fully fill the water and then prepare the soil, so as to sow the seeds; sow the soil after covering the soil; cover the mulch (immediately after emergence); in the morning or evening, water the seedbed; sow When the first hole is sown, it will not cover the earth. When the second hole is dug, the wet soil excavated from the hole will be used as the cover of the first hole.
