1, pepper planting and seedling raising
This paper mainly introduces the method of plug seedling, and obtains the seedling substrate soil through Gymboree substrate soil starter. The substrate soil starter can utilize livestock manure, deciduous bark and domestic organic garbage to provide cheap substrate soil for vegetable farmers. When producing nursery substrate soil, only one kilogram of starter can ferment nearly five tons of raw materials, and the fermentation raw materials are easily available, which is especially suitable for people who grow a large number of vegetables. At the same time, the matrix soil obtained by organic matter fermentation contains a lot of nutrients and bacteria, which can promote the growth of pepper seedlings in the later stage. The ratio of seedling soil is matrix soil: vermiculite: plant ash: 7:2: 1. In addition, some microbial fertilizers need to be supplemented. 72-hole tray is suitable for seedling raising.
2, pepper planting seed treatment
The dry weight of pepper seeds is 5-7g, and the seed consumption per mu needs120-150g. Common seed treatment methods include soaking seeds in warm soup and soaking seeds in medicine. Generally, it is appropriate to soak seeds in warm soup in a greenhouse at 55 degrees for 10 minute. If the temperature drops during this process, it is maintained by adding hot water. After 10 minutes, add cold water, cool to 30 degrees, and then soak for 8 hours. In the middle, the seeds that are not full should be soaked out. The dosage and time of drug soaking need to be accurately grasped. Soak in clear water for 4 hours, 20% sodium phosphate solution for 20 minutes, and then 10% sodium hydroxide for 15 minutes before soaking, so as to prevent virus disease. Soaking in 1% copper sulfate solution for 10 minute can prevent anthrax and bacteria. After soaking, it needs to be washed with clear water and then used to accelerate germination.
Pepper seeds are planted to accelerate germination.
Wrap the seeds with a wet cloth and place them at 25-30 degrees to accelerate germination. In the middle process, the seeds need to be washed with clean water every day to prevent rot, and the wet cloth should not be wrapped too tightly. When the seeds turn white, they can be sown.
4, pepper planting and sowing
Before sowing, water should be poured into the nutrient bowl with substrate to ensure the water needed for growth. When watering, it is necessary to ensure that the amount of water poured by each plug is consistent, so that the emergence rate is more orderly. When sowing, put the seeds into the center of the hole tray,
It is covered with a thin layer of soil. General varieties sow two seeds. If the quality of seeds is not good, they can be multicast. But after the seeds grow out, cut off the upper part of the redundant seedlings with scissors to ensure two seedlings. If the temperature is lower than 15 degrees, the plastic film can be covered to raise the temperature, and the plastic film can be uncovered when the pepper seedlings arch the soil to prevent the seedlings from burning. In addition, non-woven fabrics can also be used, and the effect is better than that of plastic.
5, pepper planting seedlings management matters
In terms of temperature, it is necessary to add a small bow shed to keep the temperature at 20-25 degrees during the day and above 12 degrees at night, but not below 10 degrees. There is no need to water, because there is enough water in the early stage. If there is fertilization such as yellowing of leaves, spray some potassium dihydrogen phosphate instead of urea, because urea is easy to cause fertilizer damage and lead to virtual growth. In addition, the plastic film needs to be cleaned regularly to ensure illumination. 7- 10 days before transplanting, gradually uncovering the film and hardening the seedlings. In the later stage, it is necessary to prevent excessive growth due to many seedlings. When the pepper seedlings grow to 7-9 real leaves, they can be transplanted.
