In the Qingming Valley rain, the warm air force is stronger and stronger, the temperature is obviously rising, and the sunshine is sufficient. Although there is still cold air influence, its power is weak.
The pot plants with strong indoor adaptability were moved to the outside. Before moving out, the doors and windows should be opened as much as possible for ventilation, so that the flowers can adapt to the external environment conditions, so as to facilitate the growth after removal.
Milan, jasmine, Epiphyllum, chandelian, balanopsis, Hewanglan, cycado, bamboo and taro flowers can be used for soil change, pruning the leaves of dead branches, weeding or fertilizer application.
For some cold resistant flowers, fertilizer can be applied in the process of changing basin, soil changing, pruning and pine soil. For example, the rose is growing branches and leaves and buds. Nitrogen and phosphorus fertilizer can be applied every 10-15 days, which is suitable for bud thinning.
This month is an important period of flower reproduction. The flowers such as Canna, gladiolus, dahlia and flower leaf taro can be propagated by root; flowers such as water bamboo, palm bamboo, Anchovis, chandelian, hairpin and Junzi orchid can be propagated separately. When dahlia is divided into roots, each plant should have 1-2 thick buds. The tuber can be taken out and planted by ball, one for a large pot, 2-3 for small stem, and 2-3 for small stem. When the tuber starts to sprout and long leaves, the large stem can be cut and divided with a sharp knife. The cut shall be covered with straw and wood ash to prevent and control the rot. The branch propagation was usually combined with turning basin. When separating, we should keep some roots in the seed plant to facilitate the future growth.
Tea flower, crab claw, Ruixiang and other flowers in winter and spring need to consume a lot of nutrients when they bloom, so nitrogen fertilizer should be applied to promote the growth of the flowers when the spring is warm and growing. For the flowers such as the blooming orchid, Zhuding red and smiling flowers, fertilizer should be stopped to prolong the flower viewing period.
April is also the golden season for the growth of meat plants
The weather warmed in April, and the meat plants reached the golden season of the year. The plants without turning basin can be turned over and soil changed, and then propagated by different plants. Indoor plants can be moved to the outside gradually, receiving sunlight and spring shower. In case of continuous rainy weather, it is necessary to prevent long-term rain, so as to avoid plant decay due to low temperature and humidity.
watering
In April, many meat plants entered the vigorous growth period, which can be watered according to the different varieties. The fast growing varieties can be watered more, while those with slow growth will be watered less. In short, it is necessary to meet the needs of water and water accumulation for plant growth. Therefore, for the growing meat plants, it is necessary to do not dry or not to pour, and pour through the water.
Generally, the watering time should be in the morning or evening of sunny weather. If water is used, the water should be dried for 2-3 days and then used to volatilize the chlorine in tap water, which is beneficial to the growth of plants.
apply fertilizer
In April, the rich and fleshy plants can be fertilized. When applying fertilizer, we should achieve "low nitrogen, high phosphorus and potassium". If too much nitrogen fertilizer will cause the plant to grow in vain, make the plant form loose and not compact, and reduce the ornamental value. In addition, a certain amount of calcium should be added, and some copper elements could be added to the cactus of the strong thorn type to promote the development of the prickles.
The fertilization of multi meat plants can be divided into two categories: base fertilizer and topdressing. The basic fertilizer is usually directly mixed into the soil when planting. The common fertilizer includes straw and wood ash, bone meal, shell powder, mature poultry and livestock manure; the dressing should be carried out according to the differences of different varieties and growth periods. New plants should not be fertilized within a month, nor do the plants with weak growth. For most of the meat plants, fertilizer can be applied once every half month, while those with slow growth can be fertilized once a month, and some of the varieties with very slow growth can not even be fertilized. Do not water the first few days before fertilization. After the basin soil is basically dry, loosen the pine soil first, and then fertilize the next day to facilitate the absorption of the root of the meat plants. Except for some species such as cactus, the osmotic pressure of the root of most meat plants is very low, and the concentration of fertilizer solution must not be too high.
The types of fertilizer should vary according to the plant variety and the growth stage. In general, the amount of nitrogen fertilizer can be slightly more in the meat plants with more leaves and green leaves, while in the differentiation and flowering stage, the result stage and the plant in the shape of globular and columnar, the leaves with red, yellow or other non green leaves should be more applied with phosphate and potassium, while stem like multi-meat plants should be more potassium fertilizer. The organic fertilizer can be used to add water to ferment bean cake, sesame cake, chicken pigeon manure, bone meal, etc. no matter what kind of fertilizer, it should be fully matured and diluted with water before use. Urea, potassium dihydrogen phosphate, calcium superphosphate and other compound fertilizers sold in the market, and special fertilizer for household flower raising can also be used in the vigorous growth period of plants, but the concentration is low and the frequency is less, otherwise soil will be bound.
