Summer shading can prevent peony leaf diseases

In recent years, the air pollution is becoming more and more serious, the disease of peony leaves is also aggravated, and the onset period is in advance, resulting in the early defoliation of peony. The phenomenon of autumn hair is serious, which affects the growth and development of the second year. Although this problem has attracted great attention, a variety of prevention and control measures have been taken, but the results are not very satisfactory. Proper shading in summer can prolong the effective growth period of tree peony, reduce leaf diseases and autumn occurrence, which is beneficial to the growth of tree peony.

The intercropping of annual tall stalk crops and peony can not only play a shading role, but also increase economic income. Here, take the intercropping of peony and sunflower as an example to illustrate.

Sunflowers usually use open-field direct seeding in the north, generally sowing seeds in the first and middle of April, and the height is basically the same as that of peonies in the first ten days of May, and the shading effect can only be achieved in June, just staggering the peak growth period and the best viewing period of peonies, and there are few sunflower diseases, so it is one of the ideal intercropping crops of peony.

The specific measures are as follows: sunflowers are planted with ridges and ridges, and the peonies are planted with a row spacing of 60 to 70 cm, three rows in one row, and a row of sunflowers in every two rows, with a plant spacing of 2 meters, which can not only effectively shade, but also provide high quality and good ventilation, and there is no strong competition for water and fertilizer in the whole growth process, which is very beneficial to the growth of peony.

The experimental results show that the shaded tree peony leaf disease has low incidence, little harm and long green leaves, which is beneficial to the growth of the second year.

Peony is a traditional famous flower in China. In the process of its growth and reproduction, it will be harmed by a variety of diseases and insect pests, or cause tender stems to fall off, leaves incomplete, or form a variety of disease spots on branches and leaves, and even cause wilt and death, affecting the ornamental value of flowers and causing economic losses.
