近年来,各地产业结构进一步优化,马铃薯保护地春早熟栽培面积逐渐增加。主要保护地栽培方式有塑料大棚、塑料小拱棚、阳畦等保护地栽培。一、栽培方法 1.塑料大棚栽培技术采用宽垄双行播种方式:即在90厘米宽的垄上播种两行,行距20厘米,株距25~30厘米,可于1月中旬播种。 2.塑料小拱棚栽培技术塑料小拱棚采用的是双膜覆盖技术,即一层小拱棚膜,另外在90厘米宽的垄上再覆盖一层地膜。
In recent years, the industrial structure around the further optimization of the potato precocious cultivation area gradually increased. The main protected areas of cultivation methods are plastic sheds, small plastic shed, sun protection and other protected cultivation. First, the cultivation methods 1 plastic greenhouse cultivation techniques using wide ridge double row sowing: that is, in the 90 cm wide ridge sow two rows spacing 20 cm, spacing 25 ~ 30 cm, sown in mid-January. 2. Plastic small shed cultivation technology Plastic small shed using double membrane covering technology, that is a small arch film, another 90 cm wide ridge and then covered with a layer of plastic film.
