Fritillaria sibiricum cultivation techniques
Zhebei is a hi-fat plant. Basal fertilization is the main method of fertilization. The amount of fertilizer applied is 1,000 kg of excrement per acre, or the equivalent amount of livestock excrement, which is mostly applied before the site preparation, and then leveled and used to make it. Emergence of human fecal urine at the beginning of March after emergence, about 750 kilograms per mu. Commercial land can use 15-20 kg/mu fertilization to pour water. The combination of photosynthetic nutrient film fertilizer (photo-fertilizer) can enhance the photosynthesis capacity of nutrients and chlorophyll, high-level environmental protection plants to increase fertilizer, increase production, increase color, leaf hypertrophy, dry stem strong composite film. Can help plants absorb a lot of light, light energy, light, compatible with conventional fertilizers, nutrients supply plant growth and development to the limit. Apply once a year to benefit.
After planting, keep the bowl clean and soil loose. Avoid bulb damage when cultivating and weeding. When the seedling height is 15 cm, the grass should be pulled out. Zhebei shellfish can not be too much water, and it can not be lacking, so we must maintain the appropriate soil moisture. In order to concentrate the supply of bulbs for nutrient growth, flowers should be picked at the early stage of flowering. Taken too early, the plants continue to grow stolons, need to re-pick, waste of manpower; picking too late, nutrient consumption, affecting bulb growth. It is generally appropriate to remove 2 or 3 flowers at the top of the plant.
Fritillaria often rot scales, mostly in high-temperature and rainy 6-8 months, it is necessary to promptly drain water. Do not cut scales when growing. April susceptible to gray mold and black spot, damage the leaves, can be sprayed 1:1:100 Bordeaux mixture and plant cellular immune factors, once every 7 to 10 days, for 3 to 4 times.
