1. Treatment of white peony buds for planting:
White peony buds are generally selected as propagation materials. The buds of peony are cut into several pieces according to their natural growth shape, and each piece is There are 2-3 buds, and the thickness of the bud flesh is more than 2 cm. It is best to cut the bud heads and plant them at the same time. If they cannot be planted in time, they should be temporarily stored. Choose a cool, dry and ventilated place, spread moist fine sand on the ground, stack the bud heads upward, and then cover with moist sand for storage. Or dig a pit for storage, and pay attention to drainage when it rains to avoid mildew.
2. White peony cultivation time:
The most suitable planting time in North China is September-October. In the south and areas with higher temperatures, it can be planted before freezing. The bud heads have already sprouted new roots, which are easily broken during planting and will affect the next year's growth.
3. White peony cultivation method:
First, separate the size of the white peony bud heads and plant them separately to ensure neat emergence and easy management. For field cultivation, the spacing between rows and plants is 50×30 cm, and 4000-4500 plants per mu are planted. The main purpose of cultivation is tourism viewing, and the cultivation method can be flexibly and reasonably selected according to the specific layout of the scenic spot. Plant in holes, place 1-2 buds in each hole, the planting depth is 4-5 cm, cover with mature soil and apply manure, and pile the covering soil into a bun shape to facilitate overwintering. Around early March of the following year, before the peony buds sprout, the steamed bun-shaped mounds of soil are dug up.
White peony field management
1. White peony cultivating and loosening the soil:
After emergence, cultivating and weeding are done 2-3 times a year. Cultivating should be shallow to avoid damaging the roots. Dead seedlings. In late October, before the ground freezes, cut off the branches and leaves 7-10 cm above the ground and build soil in the rhizosphere to facilitate overwintering. The method of "splitting the ridges and brightening the roots" is commonly used for cultivating white peony in Heze. That is, in early May of the second year after planting, gently push away the soil around the peony plants to slightly expose the roots, let them dry for 5-7 days, and then cultivate the soil. Roots can increase the ground temperature, kill insects and sterilize them, and achieve the effect of increasing yields, but the drying time should not be too long.
2. White peony root top dressing, drainage and irrigation:
From the second year onwards, top dressing 3 times a year, the first time from late March to early April, apply human feces and urine, the second time In late April, 500 kilograms of human excrement and urine were applied per mu, and for the third time from October to November, circle fertilizer was mainly used, with 1,500-200 kilograms per mu. In the third year, 750 kilograms of human manure, 50 kilograms of decomposed cake fertilizer, and 25 kilograms of superphosphate are applied per mu in late March; 1,000 kilograms of human manure are applied per mu in late April; and 1,500-2,000 kilograms of stable manure is applied in November.
Top dressing twice before harvest in the fourth year. In late March, apply 1,000 kilograms of human excrement per acre, add 10 kilograms of ammonium sulfate, and 25 kilograms of superphosphate; in late April, except for phosphate fertilizer, apply the fertilizer as mentioned above. Apply the same amount of fertilizer once more.
Every time you apply fertilizer, it is advisable to open holes on both sides of the plant and apply it. Peony likes drought and fears waterlogging, so it generally does not require irrigation. In severe drought, it is advisable to irrigate once in the evening. In rainy seasons, timely clear ditches and drains to reduce root diseases.
