许多农民朋友习惯在冬暖大棚(包括拱型大棚)春茬蔬菜收获完后,闲茬或抢播一茬夏玉米,这样做不但经济效益低,且容易损害土壤肥力。夏季若能充分利用大棚现有设施,在不影响秋延迟蔬菜生产的前提下,通过大棚加盖遮阳网或防虫网,抢播2～3茬反季节菠菜,如再巧打无公害蔬菜牌,经济效益会成倍增加。
Many peasant friends are accustomed to harvesting or sowing a row of summer maize after harvesting spring vegetables in winter warm sheds (including arched sheds), which is not only economically inefficient but also easy to damage soil fertility. If the summer can take full advantage of the existing facilities in the greenhouse, without affecting the late autumn production of vegetables under the premise of stamped through the shading net or net insecticide, snatch 2 ~ 3 season anti-season spinach, Economic benefits will multiply.
