What is the spacing between plants when planting chrysanthemums
As a famous traditional flower in China, the cultivation technology of chrysanthemum directly affects the flowering quality. Among the many planting factors, the setting of plant spacing is often ignored by novices, but in fact it hides key codes that affect plant growth. The spacing of chrysanthemum plants is standardized and the spacing benchmark parameter of chrysanthemum plants is recommended to maintain the benchmark value of 30 cm, and potted plants can be reduced to 20 cm. 5 cm of redundant growth space should be reserved during the seedling period to avoid root entanglement in the later period. Dynamic adjustment of line spacing requires comprehensive consideration of three major factors: 1. Variety characteristics: Small chrysanthemums should be kept at 20-25 cm, and large chrysanthemums should be 45 cm 2. Light intensity: Full sunshine environment can reduce the spacing by 10%. Modeling requirements: Cliff-style modeling requires an additional 15 cm of operating space, chrysanthemum cultivation supporting technical system, soil pretreatment standard adopts the "three deep and two shallow" land preparation method: ·Deep plowing 25 cm for the first time to break down the hardened layer·Deep plowing 22 cm for the second time to mix with the base fertilizer·Three times of shallow plowing 8 cm to form a planting tank Organic fertilizer application plan Apply 3kg of decomposed sheep manure +0.5 kg of bone meal per square meter, and fully mix with the topsoil. When raising seedlings in nutrient bowls, add 5% vermiculite to improve water retention.
Scientific plant spacing settings combined with standardized cultivation processes can increase chrysanthemum yield by more than 40%. It is recommended to adjust the spacing parameters every year according to plant growth and establish planting files to achieve precise management. The alternating layout of "wide and narrow rows" can not only ensure ventilation and light transmission, but also improve land utilization.
