Embodiment Construction

[0033] In order to facilitate the understanding of the purpose, technical solutions and effects of the present invention, the present invention will be further elaborated below in conjunction with examples.

[0034] 1. Field release test of alfalfa leafcutter honeycombs and nest boards

[0035] 1.1 Selection of hives and field settings

[0036] 5 sets of plastic foam nest boards, 3 sets of self-made wooden nest boards, hatching trays, 6 self-made hives. After the indoor biological characteristics test of the alfalfa leafcutter and the parasitoid trapping test, the adult alfalfa leafcutter was released in the field, and the release time and release amount are shown in Table 1. After release, nest boards were set up in the field to recover the alfalfa leafcutter bees. The self-made apiary is provided with hive doors, with the hive as the center, the hive doors are set towards the southeast and south directions, and 4 groups are respectively set up in the southeast and south di...

Abstract

The invention discloses a field pollination method for megachile rotundata. The field pollination method comprises the following steps: releasing adult megachile rotundata at the initial flowering stage of alfalfa, wherein 2000 to 6630 megachile rotundata are released per mu; building honeycombs in an alfalfa field after release of the adult megachile rotundata, wherein the honeycombs are providedwith honeycomb doors which are arranged towards the southeast direction with the honeycombs as the centers, and the distances between two adjacent honeycombs does not exceed 80 m; providing a plurality of nest boards in the honeycombs, wherein the nesting sides on the nest boards of the megachile rotundata face the honeycomb doors, and are set in a black-green color or black-blue color; observingthe nesting conditions of the megachile rotundata till the recovery of cocoons of the megachile rotundata after release of the adult megachile rotundata. By adopting the method, the megachile rotundata can be released safely and efficiently, the megachile rotundata can efficiently pollinate flowering plants, and the crop seed yield and quality.

Description

technical field [0001] The invention belongs to the application field of agricultural pollination insects, and relates to field release application of alfalfa leafcutter bees, in particular to a field pollination method of alfalfa leafcutter bees. Background technique [0002] Alfalfa (Medicago sativa), also known as alfalfa or common alfalfa, is known as the king of pastures because of its rich protein, amino acids, vitamins and various nutrients. A prominent problem encountered in the promotion of alfalfa cultivation is the lack of sufficient quantity of seeds. Due to the structural characteristics of alfalfa flowers, general pollinating insects, including bees, cannot effectively open their pollination mechanisms, and cannot achieve pollination. In addition, alfalfa flowers are self-incompatible, and the pollination rate and seed germination rate are very low, resulting in seed yield. and a decrease in quality. [0003] The alfalfa leafcutter bee (Megachile rotundata) b...
