Embodiment Construction

[0017] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0018] Cycas, commonly known as iron tree, has a peculiar shape, is evergreen in all seasons, and has a long life. It is regarded as a symbol of auspiciousness and longevity, and has a very high ornamental value. It has the reputation of "Panda of Plant Kingdom". In nature, the growth of cycads is relatively slow, and new leaves are not drawn every year. The feather leaves drawn out each time generally grow and remain for 2-5 years. Affect the growth of cycad plants for 1-several years, and if the new feather leaves that are drawn out cannot grow normally or carry out photosynthesis, it will definitely seriously affect the...

Abstract

The invention belongs to the technical field of Chilades pandava prevention in a leaf development period of Cycas revolute and particularly relates to a Chilades pandava biological-physical prevention method applied to the leaf development period of Cycas revolute. According to the Chilades pandava biological-physical prevention method, young leaves of Cycas revolute are covered with a light transmitting and ventilating shield in the preliminary stage of leaf development of Chilades pandava, so that the young leaves are isolated from Chilades pandava adults, and the Chilades pandava adults are prevented from laying eggs on the young leaves of Cycas revolute. The Chilades pandava biological-physical prevention method is completely different from a traditional Cycas revolute insect prevention method, no or few chemicals are sprayed, and therefore, the purpose of preventing the Chilades pandava from gnawing the young leaves of Cycas revolute in the leaf development period is achieved, and integrity and ornamental value of the young leaves of Cycas revolute are ensured easily. By means of the Chilades pandava biological-physical prevention method, workload is small, pollution to the environment is avoided, species are not affected, and eco-environment protection is facilitated.

Description

technical field [0001] The invention belongs to the technical field of prevention and control of the cycad leaf-pulling stage, and in particular relates to a biophysical control method applied to the cycad leaf-pulling stage. Background technique [0002] Cycas is also known as phoenix-tailed banana, fire-proof banana, phoenix-tailed pine, iron tree, etc. In the folk, the name "iron tree" is used more. Usually leaves 1-2 times a year. Cycads like warm and humid climate and sunshine. The growth is relatively slow, the stem is thick and strong, most of them have pinnate leaves set on the top of the stem, and the spore leaf balls are also born on the top of the stem. Cycad plants have always been expensive ornamental plants in the garden market, and they are generally only planted against each other, isolated or grouped in important places, in front of and behind houses, or in gardens and green spaces. The purple gray butterfly is one of its common pests. Because it eats the...
