Problems solved by technology

Existing aphids reproduce in various forms, and most of them adopt conventional greenhouses for reproduction. However, due to the large space of conventional greenhouses, low night temperature, and high humidity, aphids have a long reproductive cycle and low reproductive rate, and they are often infected with bud mold, which affects tobacco production. Reproductive speed and quality of aphids

Embodiment Construction

[0009] The method of rapid breeding of aphids during the breeding process of Aphids persicae, this method is mainly aimed at the bee breeding season when the temperature is low and the humidity is relatively high in February-March every year. The specific steps are:

[0010] A, with long 57cm, wide 37cm, the large hole floating plate of 160 holes is used as the tobacco seedling raising dish, fills the seedling raising matrix according to the conventional method and sows the tobacco seeds with the special seeding tray;

[0011] b. Place the seedling trays after planting on the three-dimensional seedling rack in the greenhouse in sequence; water, temperature and humidity control according to the regulations, until the tobacco leaves grow to four leaves and one core;

[0012] c. Select the fourth-instar wingless nymphs as the smoke beads in the greenhouse to pick up aphids, and each plant will pick up 3 aphids. After the aphids are picked up, use the control system of the greenhou...

Abstract

The invention provides a method for rapid aphid propagation in an aphidius gifuensis breeding process. The method comprises the steps of culturing tobacco seedlings by using a large hole floating tray stereo greenhouse; vaccinating aphids by using 4-instar wingless young aphids when the tobacco seedlings grow to have four main leaves and one terminal bud each, 3 aphids for each seedling, and keeping the temperature in the greenhouse at 16-28 DEG C and the humidity at 52-54% after aphid vaccination. The light supplementing time of the stereo greenhouse is set to be 18:00-6:00 every day for a bright period, 6:00-8:00 for a bright-to-dark period, and 8:00-18:00 for a dark period; in the bright period, 3 groups of light supplementing is needed, the carbon dioxide is 1000-1200ppm and the temperature is 28 DEG C; in the bright-to-dark period, a skylight window is opened, a circulating fan is started and the temperature is 18 DEG C; in the dark period, the skylight window is opened and the temperature is kept at 16-18 DEG C. The method can guarantee that the quantity of crops in the greenhouse is suitable for the growth and propagation of aphids and guarantee that the temperature and the humidity at night are more suitable for crop growth and aphid propagation.

Description

technical field [0001] The invention relates to a method for rapidly multiplying aphids during the breeding process of Aphids persicae, and belongs to the technical field of biological polystyrene waterproof coiled materials. Background technique [0002] Aphids are one of the main pests in the production of agricultural and forestry crops. The harm of aphids is particularly serious in the production of tobacco leaves. Adults and nymphs mainly suck tobacco leaf juice on the back and tender stems of tobacco leaves, resulting in short growth of tobacco beads and unbalanced nutrition, which affects tobacco production. The normal growth and development of pearls, and the honeydew secreted by aphids can easily induce the occurrence of diseases such as soot disease. At the same time, aphids can also spread a variety of tobacco virus diseases, which can easily cause the prevalence of tobacco virus diseases. The existing aphid control methods are mainly chemical control and physical...
