A kind of method of bean Dan keeping seeds

Abstract

The invention discloses a seed stocking method for clanis bilineata larvas, which is characterized by comprising the following steps that (1), a mixture of sawdust and moist and loosened soil disinfected by formaldehyde is loaded into a plastic pass box (dimension: 62*36cm), and soil depth is 10 to 15 cm; (2), after clipping, pieces of kraft paper and piece of plastic films are stitched to make into compound bags, and the compound bags are used after disinfection; (3), steel wires are bent into approximately n shapes, two pieces of kraft paper of two compound bags are opposite to each other, and edges are fixed on the steel wires; long steel wires extending out of the bottoms of the compound bags are inserted into the soil inside the pass box; (4), kudzu strips, locust tree branches with leaves or millettia pinnata branches are loaded inside the bags, the clanis bilineata larvas are placed into bags, the bags are clamped by clamps, so as to prevent the clanis bilineata larvas from combing out; the clanis bilineata larvas take and eat leaves inside the bags, and one branch is replaced after a period of time; the seed stocking method provided by the invention has the advantages as follows: 1, the seed stocking rate of the clanis bilineata larvas are high, accidental injuries caused to the clanis bilineata larvas during the process of planing the clanis bilineata larvas from the soil can be avoided; 2, the clanis bilineata larvas come into soil automatically, so that small chambers formed can not be damaged, the overwintering survival rate is improved, and the habitus of the overwintering clanis bilineata larva is improved.

Description

technical field [0001] The invention relates to the technical field of insect breeding, in particular to a method for saving soybean seeds. Background technique [0002] Doudan is a common name given by Guanyun people to the larvae of the Lepidoptera Scutellaridae insect bean hornworm (Clanis bilineat atsingtauica Mell.). Shandong, Henan and other places are also called bean worms and bean caterpillars. Bean Dan is a major pest of soybean crops, but at the same time, it is also a delicacy. The dishes made by Doudan are not only delicious, tender and refreshing, but also rich in nutrition. They also have special effects such as lowering blood fat and curing stomach cold. In Guanyun County, northern Jiangsu, Doudan is an indispensable dish for local people to entertain distinguished guests, forming the unique Doudan culture of Guanyun. The county has become the largest soybean distribution center in the country, and a soybean production chain including breeding, capture, tra...

Problems solved by technology

These two methods will destroy the original cells of the seedling insects and cause serious interference to the overwintering diapause of the bean dan. Even if it is re-buried in the soil, the bean dan will crawl around, consume a lot of energy, and its physical fitness will decline, seriously affecting the survival rate and Adult mating rate and egg production

If the crawled bean dan cannot be buried in the soil in time, it will dehydrate and die, resulting in a further decline in survival rate
