我省严寒季节较长,晚秋和早春露地条件不适于蔬菜生长发育。为争取延长栽培季节,各地创造了风障、阳畦、温床、大棚、温室等保护设施,采取不同的栽培形式,以利于排开播种,周年供应,增加蔬菜的花色品种。延后栽培延后栽培也叫晚熟栽培,为了创造适于蔬菜生长的气候条件,采取人工控制的措施,使蔬菜能在冷凉的环境中继续生长,延长收获期。例如,迟栽的茄果类蔬菜(茄子、辣椒等),在早霜来临前覆盖塑料薄膜大棚、中棚、小棚,保温防寒,延长结果期限。措施得当,可延续到11月份甚至到新年采收。我省开原老城曾采用延后栽培的形式,于新年前采收黄瓜。
Cold season in our province longer, late autumn and early spring conditions are not suitable for vegetable growth and development. In order to extend the cultivation season, various protection facilities such as wind barriers, sun beds, hotbeds, greenhouses and greenhouses have been established throughout the country. Different cultivation forms have been adopted in order to facilitate sowing and annual supply and increase the variety of vegetable varieties. Delayed cultivation Delayed cultivation, also known as late maturing cultivation, in order to create climate conditions suitable for the growth of vegetables, to take artificial control measures, so that vegetables can continue to grow in cold conditions, to extend the harvest period. For example, late-grown solanaceous vegetables (eggplant, peppers, etc.), covered with plastic film sheds, sheds and sheds before the early frost, keep cold and prolong the result period. Proper measures can be extended until November or even the New Year harvest. The original old town of Kaiyuan County in our province had adopted the form of postponed cultivation to harvest cucumber before the new year.
