What kind of growing environment is the full sky star suitable for? How do you plant it?

The full sky star has few leaves, slender branches, small and many flowers, countless white flowers, like stars, full of three-dimensional sense, can add the hazy beauty of the bouquet, is one of the most popular fresh cut flowers in the world, so what growth environment is it suitable for? How do you plant it?

First, what is the suitable growth environment for the full sky star?

The stars all over the sky like a warm, humid and sunny environment, which is more shady and cold-resistant, and grows best in well-drained, fertile and loose loam. The cultivated soil quality of slightly alkaline calcareous loam is better, and the drainage and sunshine are good. The height of the plant is more than 20 cm, the amount of irrigation is reduced appropriately, and a little drought can promote flowering, especially poor drainage or long-term rain after flowering, and the roots are easy to rot. Sex likes warmth, avoid high temperature and humidity, and the suitable temperature for childbearing is 10-25 ℃.

Second, how to plant the full sky star?

1. Cultivation of Mantianxing seedlings

Select seedlings with a height of about 15 cm in seedling bed, 2-3 plants as a clump, transplant according to 20 cm X 30 cm plant row spacing, about 8000-10000 plants per mu, slightly deeper-some favorable roots to increase, and choose rainy days or sunny afternoons to transplant, watering and moisturizing after planting, usually reproduce new roots in 3-5 days.

2. Fertilizer and water management of all over the sky

Like other grass flowers, Mantianxing has more requirements for fertilizer and water, but it is most afraid of random fertilization, concentrated fertilizer and partial application of nitrogen, phosphorus and potash fertilizer, and it is required to follow the two fertilization principles of "frequent application of light fertilizer, less and more times, complete nutrition" and "dry and wet, dry, dry and irrigated". And after fertilization, leaves and flowers should be kept dry at night, and nitrogen fertilizer should be used in the early stage after planting. Phosphorus and potassium fertilizer was the main fertilizer in the later stage.

3. Disease management of Mantianxing

The common diseases are Botrytis cinerea and stem rot. At the initial stage of the occurrence of Botrytis cinerea, 50% prohydantoin or 70% methyl topiramate wettable powder 800 × 1000 times, or chlorothalonil 1000 × 1500 times, optional, spray once a week, 3 times continuously for 4 times. Stem rot is mainly transmitted by the soil. Once the plant is infected with the disease, it should be pulled out in time, and the soil at the planting hole and the rhizosphere soil adjacent to the plant should be irrigated with 500 times of 75% dimethazone wettable powder.

The main pests are mites and aphids, which can be sprayed with 1000 times of dicofol and 1500 times of fenvalerate.

Warm reminder: Mantianxing is a persistent root plant, the persistent root left in the soil after receiving flowers can be used for production, generally leaving 5-10 cm, cut off the rest, then apply rotten organic fertilizer, ploughing, soil cultivation, watering to maintain a certain humidity, waiting for new branches to be reissued.
