Carrier plant system and construction method thereof

Abstract

The invention discloses a carrier plant system and a construction method thereof. The carrier plant is wheat, an alternative host is macrosiphum avenae, and a parasitic natural enemy is aphidius gifuensis. The initial macrosiphum avenae inoculating amount is that 200 / 300 macrosiphum avenae are inoculated in each pot of carrier plants; and the ratio of the female aphidius gifuensis inoculating amount to the number of the macrosiphum avenae during aphidius gifuensis inoculation is 1:40. The method comprises the steps of putting plastic flowerpots with the diameter of 10 / 30 cm into a greenhouse under the conditions that the room temperature is 25+ / -2 DEG C, the humidity is 60+ / -10 percent and the photoperiod is 16:8 h, and planting 30 / 90 plants of wheat in each pot; when the wheat is 5 cm in height, inoculating 200 / 600 macrosiphum avenae at second instar to third instar; singly putting into plastic covers for one day; inoculating 5 / 15 female parasitic wasps waiting to oviposit into each cover and shifting out the parasitic wasps after 8 hours. According to the carrier plant system and the construction method thereof, the bee propagation effect is good, the number of the indoor vegetable aphid populations is effectively reduced, and preventive prevention and control, sustainable prevention and control, efficient and comprehensive prevention and control, compatible prevention and control, and low-cost prevention and control are integrated.

Description

technical field

[0001] The invention belongs to the technical field of ecology, and in particular relates to a carrier plant system and a construction method thereof. Background technique

[0002] In recent years, the problems of pesticide residues and pollution in agricultural products have been frequently reported in the newspapers. Tens of thousands of people are poisoned by pesticides nationwide every year. Pesticide residues are one of the biggest problems in China's food safety. For a long time, chemical pesticides have been the mainstay of pest control in my country. At present, the coverage rate of biological control technology in China only accounts for about 5% of the total. A total of 470 million hectares of land use pesticides in my country, of which vegetables account for 23.8%; the annual output of chemical pesticides is 260,000-350,000 tons, of which 70% are broad-spectrum, highly toxic organophosphorus. In addition, the pesticide market in my country is chao...

Embodiment 1

[0029] The method for applying the carrier plant system of 'wheat-Aphids tridenti-Aphids aphids' in a small-scale greenhouse provided by the embodiments of the present invention comprises the following steps:

[0030] (1) Cultivation of wheat seedlings: select healthy, aphid-sensitive wheat seeds (the used species is AK58), soak them overnight with 30°C pure water before sowing; fill with a plastic flowerpot with a diameter of 10cm: the seedling cultivation substrate: vermiculite=10:1 , and the seedling soil with a water content of 60%, 30 wheat plants were planted in each pot, placed in a greenhouse with a room temperature of 25±2°C, a humidity of 60±10%, and a photoperiod of 16:8 (L:D) h to cultivate seedlings.

[0031] (2) Inoculation of Aphid aphid: Aphid aphid was collected from Yangling, Shaanxi in March 2011, and then the population was continuously cultivated in the laboratory. When the wheat is 5 cm high, 200 two- to three-year-old wheat aphids are connected. Then pl...

Embodiment 2

[0036] The application method of the carrier plant system of the 'wheat-Pipulus aphidum-Aphids aphidii' in the embodiment of the present invention in a medium-sized greenhouse comprises the following steps:

[0037] (1) Cultivation of wheat seedlings: select healthy, aphid-sensitive wheat seeds (the kind used by myself is AK58), soak overnight with 30°C pure water before sowing; fill with a plastic flowerpot with a diameter of 30cm by the seedling substrate: vermiculite=10: 1. In seedling soil with a moisture content of 60%, 90 wheat plants are planted in each pot, placed in a greenhouse with a room temperature of 25±2°C, a humidity of 60±10%, and a photoperiod of 16:8 (L:D) h to cultivate seedlings. .

[0038](2) Inoculation of Aphid aphid: Aphid aphid was collected from Yangling, Shaanxi in March 2011, and then the population was continuously cultivated in the laboratory. When the wheat is 5 cm high, 600 two- to three-year-old aphids are connected. Then place it alone in a...
