Problems solved by technology

However, most of the beans currently on the market come from wild collection or extensive artificial breeding.
An efficient breeding technology system has not yet been formed, leading to problems such as low soybean production, prominent supply and demand contradictions, and uneven quality of soybeans

Embodiment 1

[0012] Embodiment 1 soybean planting technology

[0013] 1.1 Selection of soybean varieties: Generally, soybean varieties with tall plants, round leaves, and many branches and vines are selected. Commonly used varieties in production include soybeans (Dongxin No. 3, Xudou series, Zhoudou series), green beans and black beans. All soybean varieties can be planted in the first two seasons, and green beans with long growth period and low temperature tolerance are better for planting in the third season.

[0014] 1.2 The environment of the place of production: choose an area without pesticide pollution and a good ecological environment. The soil is fertile, loose, and the fields with good drainage and irrigation.

[0015] 1.3 kinds of pre-treatment: After the seeds are screened, they are aired (non-exposed) for 2-3 days, and the seeds are seed-dressed; after the soil is prepared with a certain proportion of fertilizer, spray a small amount of water to make the soil moist, and the...

Embodiment 2

[0021] Embodiment 2 Soybean seed production technology

[0022] 2.1 Soybean seed selection: In November every year, dig out the 5th-instar mature larvae of the bean horn moth cultivated in the third season of diapause in the soil, and select the non-injured, black-spot-free, circling worm body, and vigorous soy bean As breeding insects.

[0023] 2.2 Preservation of overwintering species: Preserve the preferred seed worms of soybean red in the wooden box prepared with the substrate (local soil and sawdust at a ratio of 2:1) in the delivery room. The wooden box is 100cm×200cm, and about 5 instar larvae are placed 5kg, keep the soil humidity about 20% during the wintering process, and pick out the bean dans that die due to dehydration or infection.

[0024] 2.3 Warm seeds: the time is at the end of February next year, the temperature of warm seeds is 28-30°C, and the temperature can be adjusted according to the growth status of soybeans. If the power of the heating facility is ...

Embodiment 3

[0028] Embodiment 3 Soybean breeding and field management

[0029] Two days after hanging the eggs, pay attention to observe the hatching rate of the eggs to ensure the base number of hatched larvae. During the breeding period, it is mainly to prevent birds from entering the greenhouse to harm the bean larvae. After August, a large number of lepidopteran pests will appear in the greenhouse, mainly including Spodoptera litura, beet armyworm, and inchworm. Their larvae have strong competition with the bean larvae. relationship, especially when the larvae of Spodoptera litura occur in large numbers, the larvae of soybean Dan generally no longer feed, stop growing until they die. Therefore, appropriate short-acting and low-toxicity insecticides should be sprayed on bean leaves 15 days before soy bean eggs are put in to reduce the population base of pests. At the same time, according to the soil moisture, timely irrigation and water replenishment. Peanut bean is peeled twice, tha...

Abstract

The invention discloses a soybean-clanis bilineata larva one-year three-season planting and breeding mode in the field of artificial breeding of resource insects. The detailed and comprehensive discussion is made from field management, clanis bilineata larva seed production, one-year three-season soybean planting and clanis bilineata larva breeding involved in the aspect of clanis bilineata larva breeding. According to the invention, self-sufficiency of clanis bilineata eggs is realized in large-scale breeding of clanis bilineata larvae, the death rate in the clanis bilineata larva breeding process is reduced, and the breeding cost is greatly reduced. According to the soybean-clanis bilineata larva one-year three-season planting and breeding mode, the clanis bilineata larva output is increased to three times a year from one time a year in the past, the annual output and net profit of the clanis bilineata larvae on unit land are increased, the marketing duration of fresh clanis bilineata larvae is prolonged, and the current situation that the current clanis bilineata larvae are in short supply on the market is relieved. In addition, the method is simple, low in operation cost and harmless to the human body and the environment, and has important significance on efficient and standardized artificial breeding of the clanis bilineata larvae.

Description

technical field [0001] The invention belongs to the technical field of artificial cultivation of resource insects, and in particular relates to a three-season soybean-bean cultivation mode in a soybean cultivation process. Background technique [0002] The bean horn moth (Clanis bilineata) belongs to the family Lepidoptera, and its larvae are commonly known as bean dan, which is one of the main pests of soybean. The 1st to 2nd instar larvae mainly damage the top of the soybean plant, and bite the leaves into holes or bite the edge of the leaf into nicks, and generally do not migrate; at the 3rd to 4th instar, the larvae begin to increase their food intake and can turn plants to cause damage; The 5th instar is the binge-eating age of larvae, and the food intake of larvae in this period accounts for about 90% of the total food intake of larvae. The damage is more serious in the well-growing, dense and low-lying soybean fields, which has a serious impact on soybean production....
