Biological pollination method capable of achieving high fruit setting rate by adopting osmia attractant

Abstract

The invention provides a biological pollination method capable of achieving high fruit setting rate by adopting an osmia attractant. The biological pollination method comprises the steps of putting bee cocoons into a comb tube, arranging a honeycomb, cultivating a bee colony and spraying the osmia attractant, wherein the osmia attractant used in the step of spraying the osmia attractant comprises the following components in parts by weight: 3-4 parts of gardenia jasminoides extracting solution, 5-7 parts of alfalfa extracting solution, 1-2 parts of benzyl alcohol, 3-4 parts of veratric acid, 6-7 parts of lavender extracting solution, 8-9 parts of gamma-nonanolactone, and 3-4 parts of maltose. After the pollination is carried out by adopting the osmia attractant, the fruit setting rate is obviously increased, and the fruit setting rate of rosa laevigata reaches 94.8-96.8%; the bee attraction quantity in per square meter of a planting area during pollination to the rosa laevigata reaches 0.945-1.079; the pollination rate of the rosa laevigata is 96.4-98.2%.

Description

technical field

[0001] The invention belongs to the technical field of biological pollination, and relates to a biological pollination method using an attractant, in particular to a biological pollination method with a high fruit setting rate using a wasp attractant. Background technique

[0002] The wall bee has the advantages of early activity in early spring, low temperature resistance, high reproduction rate, small activity range, easy management, and many types of plants that the wall bee collects pollen.

[0003] Pollination by using wasps has a broad prospect, but under natural conditions, many plants have poor attracting effects on wasps, and the pollination effect is not good, and bees attractants can be used to assist pollination. The current pollination technology of the wall bee is mainly to put the wall bee into the planting area to make it pollinate naturally.

Embodiment 1

[0029] Embodiment 1 A kind of wasp attractant

[0030] The wasp attractant comprises the following components by weight:

[0031] 3 parts of gardenia flower extract, 5 parts of alfalfa flower extract, 1 part of benzyl alcohol, 3 parts of veratrol, 6 parts of lavender extract, 8 parts of nonalactone gamma, 3 parts of maltose

[0032] Preparation:

[0033] (1) Preparation of gardenia extract

[0034] Take fresh gardenia, wash it, squeeze it in a press for 7-10 minutes, then filter it with a 200-mesh filter cloth, discard the filter residue, collect the juice, centrifuge at 5000 rpm for 10 minutes to obtain the supernatant, and filter it through a 0.45 μm microporous membrane Afterwards, the gardenia flower extract was obtained.

[0035] (2) Preparation of alfalfa flower extract

[0036] Take vigorously blooming alfalfa flowers, crush them, put them into 60% ethanol, whose weight is 10 times that of alfalfa flowers, soak for 12-13 hours, filter through 80 mesh gauze, and cent...
