Consultation: What kind of pepper leaves become hard, inconspicuous, and dark in color?
Answer: 1. Water shortage during the seedling stage, especially when using seedlings for seedlings, because each hole volume is poor and buffer capacity is poor, management can not keep up, it will cause water shortage, if watering is not timely or repeated many times Water shortage will lead to dark green leaves, thickening and hard growth. 2. There was no timely pouring of water after planting, and the plants were soaked with water, which prolonged the time of seedling emergence and showed the phenomenon of small old seedlings. 3. The large amount of fertilizer or organic fertilizer is not fully decomposed, coupled with inadequate irrigation, resulting in a certain degree of root and plant water shortage.
Solution: Choose a sunny day to pour a muddy water, raise the temperature of the canopy 2 to 3 days after watering, and release the wind when the temperature reaches 30 to 32 degrees at noon. 10 to 15 days before pouring, if the fertilizer is insufficient, you can also follow the water topdressing urea 5 kg / mu.
