目前,黄瓜生产中主要采用两种采种方式。一种是保护地采种,3月上中旬温室育苗,4月中下旬定植于温室或塑料小拱棚里,晚霜期过后,撤除保护设施,6月上中旬即可收获种子。另一种是露地采种,“春分”前后育苗,5月上旬定植于露地,7月上旬采收种子。此外,也可在生产田里选择瓜码密、瓜条性状好、无病虫害的植株,每株选1～2条种瓜,做好标记以备采种。无论采用哪种采种方式,都必须掌握好以下几个技术环节。
At present, the cucumber production mainly adopts two kinds of seed collection methods. One is the seedlings planted in the protected areas. In March, the nurseries are raised in the middle of the greenhouse. The plants are planted in small greenhouses or small plastic sheds in mid to late April. After the frost period, the protective facilities are removed and the seeds can be harvested in mid-June. The other is open field mining, “vernal equinox” nursery before and after planting in early May planted in the open, early July harvest of seeds. In addition, you can also choose melons in the production of dense fields, the characteristics of a good fruit, pest-free plants, each plant selected 1 or 2 kinds of melons, marked for the preparation for seed collection. No matter what kind of mining methods used, we must master the following several technical aspects.
