Flowers are becoming a new industry. Planting grass and flowers to improve the ecology and beautify the environment can also cultivate people's sentiments. With the improvement of living standards and cultural literacy, potted flowers are more and more popular with people.
A wide variety of flowers, their growth habits are different. Due to the fact that humans have carved too much of their weight, such as easy cultivation, degeneration breeding, potted plants, etc., the difficulty of cultivation has increased. Fertilizer, in particular, has become one of the keys to success.
In the form of flower cultivation, there are generally open field cultivation (gardens, flowers, flower beds) and potted plants. In the use of fertilizers, there are mainly basal fertilizers and top dressings. Biogas fertilizer has many advantages in cultivating flowers: smooth fertilizer effect, comprehensive nutrient, long fertilizer effect, and concurrent treatment of diseases and insects, which are even better than certain flower special fertilizers.
First, open cultivation
1, base fertilizer in advance two weeks, combined with site preparation, 2 kg per square meter of biogas residue, mix well. If it is a hole plant, depending on the size of the plant, 1 to 2 kg per hole, cover soil 10 cm, and then plant. The best varieties are best not to put the base fertilizer, but instead to loosen the loam soil, planting live after the fertilization.
2. Topdressing Topdressing should be strictly controlled according to needs. Different flower varieties need different fertilizer absorption capacity. Therefore, the application of biogas fertilizer should be different. Seed flowers, herbaceous flowers, and leafy flowers are growing faster. The biogas slurry can be applied in January and the concentration of 3 parts of biogas slurry is 7 parts. Slowly growing flowers, woody flowers, flower and fruit flowers, according to the requirements of their growth period, 1 part of biogas slurry plus 3 parts of fresh water top dressing. Acupoints: digging points can be used at the root tip, using biogas slurry, biogas residue mixed application, according to the size of the plant, each hole Shi 0.5 to 5 kg range.
Second, potted plants
1. Prepare soils with maturity of more than 3 months in the cultivation soil and blend well with well-weathered mountains and soils. The ratio is: 1 kg of fresh biogas residue, 2 kg of mountain soil, or 1 kg of dry biogas residue and 9 kg of mountain soil.
2, change potted plants 1 to 3 years after planting, need to change soil, expanding. The general varieties can be filled with the culture soil prepared by the above method. The rare species needs to add a little silicon fertilizer to reduce the content of biogas fertilizer. Where new planting, change potted flowers, do not see new leaves do not topdressing (20 to 30 days).
3. The top-dressing potted flowers generally have less plants and less nutrients and need artificial supplements. However, it is not the time to make up for it. The quantity is not accurate. It is the key to potted flowers, especially the cultivation of flowers on the balcony. Camellia (represented by Camellia) requires that the top dressing is thin and sparse, that is, the frequency is small and the concentration is thin. From March to March, one batch of biogas slurry was applied every month, and the concentration was 1 part of biogas slurry plus 1 to 2 parts of fresh water. Seasonal flowers (represented by Chinese rose flowers) can be applied to marsh fertilizer once in January. The proportion is the same as above, and it is suspended from September to October.
Third, pay attention to matters
1. The biogas fertilizer must be fully decomposed, especially the biogas residue, and the new biogas residue can be stored in the barrel for 20-30 days before use.
2. Before biogas slurry is used as top dressing and foliar fertilizer, it should be open for 2 to 3 hours.
3, biogas fertilizer potted plants, should calculate the dosage, avoid urgency, excessive fertilization.
After fertilization, falling leaves, as the concentration is high, should be promptly hydrolyzed or change the soil: If the edge of the tender leaves is watershed off, as water and fertilizer poisoning, should be timely off-pot soil, pruning, shading maintenance .
