Summer shade prevents peony leaf disease

Peony is the traditional name of our country. During its growth and reproduction, it will be harmed by various pests, or the tender stem will fall off, the leaves will be incomplete, or various lesions will form on the branches and leaves, and even cause death. Affect the ornamental value of flowers and cause economic losses.

In recent years, the pollution of the air has become increasingly serious. The diseases of the peony leaf have also been aggravated and the onset of the disease has advanced, causing the peony to fall off in advance. Autumn has been found to be very serious, affecting the growth and development of the second year. Although this issue has attracted a lot of attention and has taken a variety of prevention and control measures, the effect is not very satisfactory. Through observation and practice, the authors have proved that proper shading in summer can prolong the effective growth period of peony, reduce leaf diseases, and reduce autumn findings, which is conducive to the growth of peony.

Intercropping high-stalk crops with peony can not only play a role in shading, but also increase economic income. Here is an illustration of Peony and Sunflower.

Sunflowers are often exposed in the open air in the north, usually seeded with seeds in mid-April. The basic height is consistent with that of peony in early May, and the shading effect can be achieved in June. It is just a matter of staggering the peony`s vigorous growth and optimal viewing period, and the sunflower disease. Not much is one of the ideal intercropping crops of peony.

The specific approach is: sunflowers are planted in ridges and ridges, peony is lined with 60 to 70 centimeters, a row of 3 lines, each row of sunflowers is planted in two rows, and the distance between the rows is 2 meters. This will not only effectively shade, but also provide good ventilation. There is no strong competition for water and fertilizer during the entire growth process, which is very beneficial to the growth of peony.

Through experiments, the incidence of shady Peony leaf disease is low, the degree of harm is small, and the green leaves are kept for a long time, which is conducive to the growth of the second year.
