Step S1. sowings, field planting：Homozygous male parent and homozygous female parent are sowed in heliogreenhouse, are colonized, wherein,
Homozygous male parent is than homozygous maternal 6~8d of planting early enough.
Breeding is carried out using heliogreenhouse, the factor such as temperature, humidity, illumination effectively in control greenhouse, may advantageously facilitate
The growth of cucumber plant, pollination breeding.
Further, the summer fallow phase for choosing heliogreenhouse carries out hybrid seed production of cucumber, for example, utilizing heliogreenhouse grass
Certain kind of berries production time out carries out summer hybrid seed production of cucumber.More specifically, cultivating the heliogreenhouse of strawberry using spring stubble, uproot plants after their edible portions have been harvested.
Then summer hybrid seed production of cucumber is carried out, kind melon is pollinated to be harvested and uproot plants after their edible portions have been harvested the latter moon, then is colonized strawberry.It is possible thereby to improve day
The utilization rate in light greenhouse, reduce production cost.During summer hybrid seed production of cucumber, air port and doorway are taken off in heliogreenhouse
Place fly net, it is ensured that the intact no breakage of canopy film.
Using matrix hole plate seedling growth, to ensure that paternal plant has the pollen source of abundance, homozygous male parent is than homozygous maternal early sowing
6~8d of kind, or planting early enough 7d.The seed of homozygous male parent is first sowed, sows the seed of homozygous female parent after 6~8d again.
When paternal plant or maternal plant grow into a leaf wholeheartedly, the field planting of high ridge single file, 55~65cm of line-spacing, spacing in the rows 15
~25cm, plantation density are 5000~6000 plants/acre, and the field planting ratio of paternal plant and maternal plant is 1:2~4, Huo Zhewei
1:3。
Step S2. maternal plants manage：During maternal plant grows to 2~6 leaves, with 38~42wt% ethephon (CEPHA),2-(chloroethyl) phosphonic acid pair
After maternal plant carries out 2~4 spraying treatments, the male flower that is remained on artificial removal maternal plant.
