Description

Method for increasing yield of orychophragmus violaceus seeds and assorted osmidus chinensis nest box
Technical Field
The invention relates to the technical field of green manure crop or ornamental plant seed production, in particular to a method for improving the yield of February orchids through osmia panzer and an attractant, and also relates to an osmia panzer honeycomb matched with the osmia panzer.
Background
Osmia belongs to a genus osmia in the general bee family (apoidea) and the family melissa (megachilidae). The osmia panzer, the bumblebee, the Chinese bee and the like can be used as pollinating bees, but the living and flower visiting mode of the osmia panzer is different from that of the general pollinating bees. The osmia panzer lives independently, each female bee can grow, and the female bees can independently complete the work of sucking nectar, collecting pollen and breeding offspring after mating. The osmia panzer interview flower is of a top collection type, and the observation of the behavior of the diagonal osmia panzer by people such as Japanese scholars, namely the Tiantaisheng and the like thinks that when the osmia panzer interviews the flower, the contact rate of the pollen carried by the osmia panzer and the flower stigma of the interview flower is 100 percent. Therefore, the osmia panzer is a good pollination insect of brassicaceous vegetables such as Chinese cabbages, rapes and radishes, rosaceous fruit trees such as apples, pears, peaches, cherries, apricots and plums, kiwi fruits and the like. Although February is the same as a crucifer crop, no report on the application of osmia to auxiliary pollination and seed production of February exists at present.
February belongs to early spring flowers, has long flowering phase, is cold-resistant, drought-resistant, yin-resistant and less in plant diseases and insect pests, and is an indispensable green manure crop or ornamental plant for viewing green in winter and flower in early spring in northern areas of China. In the initial flowering period of February, the gas temperature is low, the flower fragrance is light, and osmia is easily attracted by the fragrance of other early-spring green manure or ornamental plants (such as vetch, vetch and the like), so that the pollination effect is greatly reduced, and the seed yield is further influenced. Application of attractants is a common method of increasing pollination and fruit set in an open environment, as exemplified below.
The invention patent application 201510346938.3 discloses a biological pollination method with high fruit set percentage by using a osmia attractant, wherein the components of the osmia attractant in the step of spraying the osmia attractant comprise 3-4 parts of gardenia extract, 5-7 parts of alfalfa flower extract, 1-2 parts of benzyl alcohol, 3-4 parts of veratric acid, 6-7 parts of lavender extract, 8-9 parts of propyl nonalactone and 3-4 parts of maltose.
The invention patent application 201510345874.5 discloses a biological pollination method and application thereof in planting of wild jujube trees in saline-alkali soil, wherein the osmia attractant comprises the following components in parts by weight: 7-8 parts of benzyl alcohol, 10-12 parts of veratric acid, 4-6 parts of lavender extract, 10-12 parts of propyl nonalactone, 4-6 parts of maltose, 3-5 parts of gardenia extract and 7-8 parts of alfalfa flower extract.
The invention patent application 201510345890.4 discloses a method for biological pollination by osmia panzer and application thereof in hawthorn tree saline-alkali soil planting, wherein the osmia panzer attractant comprises the following components in parts by weight: 2-3 parts of benzyl alcohol, 5-6 parts of veratric acid, 4-5 parts of lavender extract, 9-12 parts of propyl nonalactone, 5-8 parts of maltose, 4-5 parts of gardenia extract and 8-10 parts of alfalfa flower extract.
The invention patent application 201610421143.9 discloses an Osmia attractant for pollinating pepper, which provides an Osmia attractant for pollinating pepper, comprising pepper male parent pollen extract, a first aromatic, a first sweetener and water, and a first aromatic, wherein the composition of the first sweetener is selected from date honey and/or sophora honey. At least one of an antibacterial agent, a second flavoring agent, and a second sweetener. The antibacterial agent comprises at least one of streptomycin, gentamicin, kanamycin, chloramphenicol and tetracycline; the second aromatic comprises at least one of fructus Jujubae essence, fructus Mali Pumilae essence, fructus Pyri essence, fructus Persicae essence, flos Osmanthi Fragrantis essence, fructus Citri Grandis essence and fructus Citri Limoniae essence; the second sweetener comprises at least one of jujube flower polysaccharide, sophora flower polysaccharide, apple polysaccharide, pear flower polysaccharide, peach polysaccharide, cherry polysaccharide, corn syrup, rice syrup, fructose syrup, maltose, sucrose and maltose.
General analysis of published related patent applications, the composition of osmia attractant generally includes components such as sweeteners, flavoring agents, adjuvants (bactericides, adhesives), and the like, which are basically artificially extracted or synthesized substances. There are problems including: the price is higher, and the production cost of a user is increased; the extraction process is complex and is inconvenient to popularize and utilize; the excessive application of individual chemical substances can pollute the ecological environment and affect the pollination of osmia and the quality safety of agricultural products.
