Problems solved by technology

[0004] Aiming at the problems in the prior art that crops suffer from diseases and insect pests that cause crops to decrease or die, and spray pesticides to cause drug residues, the present invention provides a device and method for preventing crop seedlings from suffering from pests. Through the protective device, when plant seedlings are just unearthed or the aboveground parts of plants are just When young leaves grow, protect the crops, avoid the erosion of diseases and insect pests, improve the survival rate of crops, replace pesticide spraying, and produce green and healthy food

Embodiment 1

[0024] In this embodiment, take Chinese cabbage planting as an example, as figure 1 As shown, the protective device is mainly used to prevent and control aphids in Chinese cabbage, and Chinese cabbage is most susceptible to diseases in the seedling stage, that is, before the seedlings have 6-7 leaves. The Chinese cabbage eroded by aphids cannot wrap the heart or grow slowly. The leaves are shrunken and uneven, and they are mostly covered with small gray-brown necrotic spots, which lose their edible value. Through the protective device of the present embodiment, it is protected at the seedling stage of Chinese cabbage, and the protective device adopted includes a support, a protective net cover 3, and the support includes a fixed frame 1 for fixing the protective net cover 3, and is connected with the fixed frame 1. The supporting rods 2, wherein three supporting rods 2 are arranged on the periphery of the protective net cover 3, the fixed frame 1 is located at the top of the t...

Embodiment 2

[0033] In this embodiment, the specific structure is similar to that of Embodiment 1, the difference is that the bracket also includes a base 6, the base 6 is a hollow double-layer structure, and the inner layer 17 of the double-layer structure is sleeved on the outer layer 18 The inside of the inner layer 17 and the outer layer 18 form a gap like this, which can pass through the protective net cover 3. The protective net cover 3 in the present embodiment also selects gauze for use, and the bottom of the gauze is separated from the inner layer 17 and the outer layer 18. The gaps between the outer layers 18 are passed through and the ends of the scrim protrude beyond the bottom end of the double layer structure.

[0034]For the installation of the protective device in this embodiment, the top of the protective net cover 3 is sealed between the upper fixed frame 7 and the lower fixed frame 9 of the fixed frame. This embodiment adopts 4 support rods 2, and the fixed frame is selec...

Abstract

The invention belongs to the field of agricultural cultivation, and particularly relates to a protection device and method for preventing crop seedlings from suffering from pests. The device comprises a support and a protection net cover, the support comprises a fixing frame used for fixing the protection net cover and multiple support rods connected with the fixing frame, the support rods are arranged on the periphery of the protection net cover, the fixing frame is located on the tops of the support rods, and the top ends of the support rods are fixed inside the fixing frame. The protection device with the size in accordance with the sizes of plant seedlings is manufactured according to the plant cultivation mode, and when the plant seedlings just come up or the overground parts of plants just send forth tender leaves, the plant seedlings or the tender leaves are covered inside the protection device. By means of the protection net cover, the plant seedlings just coming up or the plants with the overground parts just sending forth the tender leaves are protected, the pests cannot enter the protection net cover, the growing environment of the pests is effectively protected, the protection net cover is good in ventilation and light transmission, the plants can be protected, growth of the plants cannot be affected, and meanwhile the protection device is convenient to assemble and disassemble and convenient to carry.

Description

technical field [0001] The invention belongs to the field of agricultural planting, and in particular relates to a protective device and method for preventing crop seedlings from being subjected to pests. Background technique [0002] In the process of agricultural production, picking seeds and cultivating plant seedlings are very important links. In the actual production process, affected by the external environment of plant growth, it is often difficult to cultivate and ensure the health of plant seedlings without manual intervention. growing up. When the plant seedlings have just emerged from the soil or the aboveground parts of the plants have just grown young leaves, the plants are vulnerable to pests. Pests not only feed on young leaves or seedlings, but also ovulate on plants to harm the growth of plants. In this case, it will affect the growth of plants in light cases, and cause the plants to die in severe cases. The value of different plant varieties is also relati...
