Before the planting of white peony
First turn over
Before the planting of the white peony, the land is sorted and the depth of the land is more than 20cm, and the group is consolidated into a 1.2m wide field. Because the white pheasant is also afraid of cockroaches, it is necessary to reserve a drain.
Second turn over
Each mu of land needs to mix 400-500 kg of filtered calcium acid (phosphorus fertilizer) to relax the soil again.
Prevention of pests and diseases
The second amount of groundwater (insecticide) is used to kill surface and underground pests after the second turn. The commercial part of the white peony is part of the underground stem, so the prevention of underground pests and diseases is very important.
White scorpion is afraid of direct sunlight in summer. For the convenience of operation, it is best to make a awning before the seedlings. It is recommended to use a 45-mesh shade net. The qualified farmers can also install the spray system at the same time to facilitate scientific management in the future.
White carp planting - increase
Take a shower before going down to the ground
Zhongnong 213 white peony seedlings are planted with rooting powder and water for 2-3 minutes to soak the roots, but the speed of growth of white roots is increased by 1 - 1.5 times.
Small mulch says more
The 1.2 m wide field is suitable for a 1.5 m wide film.
Ground film type
PE transparent film, low cost, can maintain the soil moisture has a certain thermal insulation effect
Recommended index ★ ★
PE black film, due to the black glow and heat characteristics, on the basis of the transparent film moisturizing and heat preservation, the effect of the tail land warming is increased.
Recommended index ★★★★
PEVA two-color film, gray and gray two-color double-layer structure, heat preservation, moisturizing and better temperature-increasing performance. At the same time, the film has a longer service life and is more resistant to weathering. Compared with single-layer film PEVA, it has stronger resistance to foreign pests and diseases. It is opaque, and the sanding can completely block the sunlight, which can completely inhibit the growth of weeds.
Recommended index ★★★★
Field topdressing - for
It is recommended to use 1.5 ‰ seaweed fertilizer solubilizer, once every half month, about 1.5 kg each time. Or use compound fertilizer, but must be washed after fertilization, a little careless will burn the seedlings affect plant growth. Farmyard manure can also be used.
Small knowledge points, the choice of potassium-containing fertilizer is conducive to the growth of white tuber.

There are no shells and the same snail habits. During the day, they hide nighttime activities, and the main buds of leaf buds, flower buds, new leaves and young roots of Dendrobium candidum. Control method: manual capture, in the morning is better; lime under the seedbed, snail enemy on the seedbed.
