Embodiment 1

[0070] 1. Fertilize and prepare the plot

[0071] 10 cubic meters of organic fertilizer and 50 kilograms of three-element compound fertilizer are applied per mu. After evenly spreading, rotary tillage is carried out to make a flat border with a width of 2 meters and a north-south direction. 2. Live broadcast of dried seeds

[0072] 2. Live broadcast of dried seeds

[0073] The greenhouse can be sown except from July to August, it should be early rather than late. The double row hole seeding machine was used to adjust the row spacing to 30 cm and the hole spacing to 15 cm for sowing. The amount of seed per mu is 1.5kg. The stubble of chives on the market during the Spring Festival is sown in May. From April 1st to July 15th, it should be early rather than late. The double row hole seeding machine was used to adjust the row spacing to 30 cm and the hole spacing to 15 cm for sowing. The amount of seed per mu is 1.5kg.

Abstract

The method comprises the following steps: isolating a sterile line and a maintainer line of Chinese chives by adopting a mesh bag during hybridization and matching, and pollinating by utilizing bumblebees in a flowering phase; then carrying out leek breeding; or the selected single Chinese chive selfing line or the selected Chinese chive selfing line and sterile line plants are relatively more, a net shed is adopted for isolation when planting is concentrated, and bear pollen is adopted for pollination in the flowering phase; then carrying out leek breeding; or when a single leek inbred line or a single leek sterile line and a single leek inbred line are completely planted in the whole greenhouse, bumblebee pollination is adopted in the flowering phase, the whole greenhouse is covered with a gauze, and gauze door curtains are hung on the two sides of a door and a buffer room channel opening; and then carrying out leek breeding. The seed quantity of the breeding material in the breeding process is greatly increased, a large amount of labor is saved, the operation is simple and convenient, and the breeding process is shortened to a certain extent.

Description

technical field [0001] The invention relates to the technical field of leek breeding, in particular to a method for leek breeding using bumblebee pollination in a greenhouse. Background technique [0002] Leek is a perennial perennial root vegetable of the Liliaceae family. It is an umbel covered by a cone-shaped involucre with 20-30 florets. The florets are bisexual, with white corolla, 6 tepals and 6 stamens. Ovary superior, cross-pollination. In mid-August, the plants bloom one after another, and they enter the full bloom period from late August to early September. The fruit is a capsule, the ovary is 3 rooms, there are two ovules in each room, and the seeds are black. The florets of an inflorescence begin to open from the side flowers. The pistils begin to expand about 3 days after the florets open. The optimum pollination period is one day after the florets open. Pollination can be performed within 48 hours. In the past, leeks were pollinated by artificial bagging a...
