Method for prevention and control of phyllotreta striolata of Chinese flowering cabbages by carpet type coverage with insect-proof nets

Abstract

The invention discloses a method for prevention and control of phyllotreta striolata of Chinese flowering cabbages by carpet type coverage with insect-proof nets. The method includes steps: 1) killingphyllotreta striolata eggs in soil, and sowing; 2) covering the ground with the insect-proof nets, and compacting all around with soil; 2) after coverage with the nets, spraying water and fertilizersto enable contact of the seeds with soil; 4) 5-15 days later, removing the nets, and eliminating adult phyllotreta striolata. By direct coverage of the ground with the insect-proof nets, greenhouse construction is avoided, and accordingly simplicity in operation, material saving and labor saving are realized; the insect-proof nets directly cover the ground and completely contact with the Chineseflowering cabbages and the ground, so that phyllotreta striolata cannot immigrate for spreading harms, and great prevention and treatment effects are achieved; by soil treatment before sowing, potential larvae and eggs of phyllotreta striolata in soil can be killed so as to eradicate hidden sources of injurious insects; low cost in prevention and control is realized.

Description

technical field [0001] The invention relates to the field of flea beetle control, in particular to a method for preventing and treating the flea beetle by covering the insect-proof net with a carpet. Background technique [0002] Flea beetle is the main pest on cabbage hearts in South China. At present, field control mainly relies on spraying a large amount of chemical pesticides. The high cost of control will also bring negative impacts such as environmental pollution and pesticide residues. With the continuous improvement and emphasis of the government and the people on the safety of the ecological environment and the quality of agricultural products, the green pest control technology will gradually replace the traditional chemical pesticide control and become the first choice for pest control. In addition to chemical control, the most effective method is to use insect nets to control flea beetles. However, there are some problems in the current usage methods, which are b...

Problems solved by technology

[0003] One is to use stainless steel materials to build insect-proof net greenhouses. This method occupies a large area and is expensive. During the planting and harvesting process, staff frequently come and go. Flea beetles are very easy to invade and reproduce. Practice has proved that insect-proof net greenhouses are very effective for vegetable heartbeat The control effect did not achieve the desired effect;

[0004] The second is to build a small arch shed with bamboo chips. Compared with the insect-proof net greenhouse, this method has lower cost and better control effect, but the field operation is complicated. Each kind of cabbage needs to build a small arch shed again, which is time-consuming and laborious. Watering and fertilization in the later stage requires Remove the insect net first, the operation is complicated and very inconvenient

[0005] In general, there are the following problems: 1, the traditional chemical control method, will begin to spray chemical pesticides as soon as the cabbage sprouts. The control effect and the price of pesticides are constantly increasing, resulting in higher and higher control costs; 2. The construction of stainless steel insect-proof net greenhouses has a complex structure and high cost, and the greenhouses are easily damaged by birds, mice or personnel. , the top of the greenhouse is easy to accumulate leaves, dust and other sundries, which will affect the light transmittance of the greenhouse, affect the growth of crops, and the maintenance cost in the later period is high, and practice has proved that the anti-insect net greenhouse is not effective for flea beetle control; 3. Build a small arched shed with bamboo chips , each needs to be re-built once, and the building speed is slow and the operation is complicated, especially in the later stage. Other operations are inconvenient, resulting in a large labor investment. Once a corner is not sealed, jumping armor can invade and damage the entire arch shed
