What are the cultivation techniques for pollution-free green peppers?

 1. Seed treatment

Use two parts boiling water to one part cold water, soak seeds in warm water at 55°C, with water being 5 times the volume of the seeds: pour in the seeds and stir constantly, keeping at a constant temperature for 10 minutes; when the water temperature drops to about 30°C, stop stirring and continue soaking for 12 hours, then skim off the shriveled seeds. Control the sprouting temperature at 20°C~28°C, rinse once every day, and use dehydration and temperature alternation treatment.

2. Nutrient soil preparation

The seedbed soil should use surface soil from vegetable fields that have not grown solanaceous crops for more than 3 years, and the fertilizer should be fully decomposed and fermented horse manure, stable manure, dried night soil, etc.; for each square meter of sowing bed soil, use 0.008 kg of a 1:1 mixture of 50% carbendazim and 70% thiophanate-methyl, mix with the bed soil and sift, and the soil for the transplanting bed should be basically consistent with that of the sowing bed.

3. Sowing

When 50% of the seeds have sprouted, they can be sown, with medicated soil spread on the bottom and covered on top.

4. Management from after sowing to before transplanting

Control the daytime temperature at 28°C~32°C and the nighttime temperature at 18°C~20°C; seedlings can emerge in 6~7 days, sprinkle a layer of fine soil to fill the cracks, preserve moisture and prevent lodging, and after the seedlings are fully emerged, control the daytime temperature at 25°C~28°C and the nighttime temperature at 15°C~20°C. Thin the seedlings in time, and focus on low-temperature hardening of the seedlings 3 days before transplanting.
