Embodiment 1

[0020] This embodiment is an embodiment of the method of the present invention, and three processing tests have been done in the planting mode of the parents.

[0021] The three treatments in this example are A1, A2 and A3 respectively, and the test materials for the three treatments are the cucumber hybrid combination provided by Syngenta, the female parent AF0309 is the female line material, and the male parent AF020 is the hermaphrodite plant material, the sowing date of the three treatments is August 20, and the planting period is September 2; the sowing period, the planting period, field management, and pest control of the three treatments are all conventional technical measures in the art and are all the same. The test steps are as follows:

[0022] 1. Construction of isolation net room

[0023] Build three isolation net rooms on the suitable land of soil fertility and do three processing uses respectively, and the construction of described three isolation net rooms is ...

Embodiment 2

[0043] The present embodiment is the test of the bee releasing time of the inventive method, and 5 treatments are set, respectively B1, B2, B3, B4, B5; the used test materials of the five treatments all select the cucumber hybrid combination provided by Syngenta , the female parent AF0309 is a female line material, and the male parent AF020 is a monoecious plant material, and adopts the planting method of processing A2 in Example 1. In order to determine the best time for releasing bees and pollination, the following tests are carried out, and other test steps are all the same as the implementation Example 1 is the same.

[0044] 1. Determination of release time

[0045] B1, B2, B3, B4, the bee release time of B5 were originally selected in 3 days, 4 days, 3 days, 4 days, 5 days before the female flowers of more than 7 nodes opened, and the beehives were moved into the net room.

[0046] 2. Test method

[0047] The test was carried out in five isolation net rooms respectivel...

Embodiment 9

[0078] Embodiment 9 is the embodiment of the inventive method

[0079] In Example 9, except that the male parent material used is the female line material CF090, and the following male flower induction treatment is performed, and the female parent is the same parent AF0309 used in Example 3, the rest of the steps are the same as in Example 3. When harvesting, investigate the number of results per plant, the number of seeds per fruit, the seed yield per plant, and the weight of 1,000-seed seeds. Each plot counts the yield respectively, and compares them with Example 3, see Table 7 and Table 8.

[0080] Male flower induction treatment: When the male parent seedlings grow to 3 leaves and 1 heart, and the diameter of the third true leaf is 2-4cm after flattening, use 250mg / L silver thiosulfate solution to spray the small watering can to grow Spots and young leaves are sprayed, and the young tissues of the whole plant should be fully moistened. Treat once every 3-4 days, and treat ...

Abstract

The invention discloses a method for cucumber hybrid seed production by honeybee pollination in a net room, and belongs to the technical field of crop hybrid seed production. The method comprises that: insect preventing gauze is used to erect an isolation net room, and the net room has the floor area of more than or equal to 200m<2> and the height of more than or equal to 2.5m; a cucumber inbred line of a female line is taken as a female parent and a cucumber inbred line is taken as a male parent; a row ratio of the male parent to the female parent is 1:3; Apis mellifera ligustica Spinola is used for pollination; when the floor area of the net room is more than or equal to 200m<2> and less than 667m<2>, a bee hive is put in the net room and 4 to 6 combs exist in the bee hive, wherein each comb has 1 to 3 brood combs; and when the floor area of the net room is more than or equal to 667m<2>, 1 to 2 bee hives are put in the net room and 6 to 8 combs exist in each bee hive, wherein the brood combs are more than or equal to 3, and the period of pollination is 20 to 30 days. The method improves per mu yield of seeds by 42 percent, reduces manpower by 50 man-day / mu and improves net income by 81 percent compared with hand pollination in open field, and improves per mu yield of the seeds by 22 percent, reduces manpower by 33 man-day / mu and improves net income by 36 percent compared with hand pollination in the net room.

Description

technical field [0001] The invention relates to the technical field of hybrid seed production of crops, in particular to the pollination technology of cucumber hybrid seed production. Background technique [0002] Cucumber is an annual cross-pollinated crop with unisexual flowers and monoecious plants. Before the 1970s, conventional varieties were mainly used in production, and after the 1980s, the first-generation hybrid varieties were mainly used. With the continuous improvement of the popularity of hybrid seeds and the continuous influx of foreign varieties, the requirements for the purity of hybrid seeds and the yield of seed production are also increasing. higher. When two parents of monoecious plants are used for hybrid seed production, a large number of male flowers will appear on the female parent plant, and there will be relatively few female flowers. In the production process of emasculation, flower pricking and pollination, if manual operations are not serious, h...
