蔬菜日光温室高效种植模式的研究

Studies on Planting Patterns of Vegetables in Solar Greenhouse

在３种类型的日光温室中进行了４种种植模式的比较试验。结果表明，３种类型的日光温室在最冷的１月份最低温度均能保持在４℃以上，以当前河北省中南部地区流行的ＣＫ型日光温室保温效果最好；４种种植模式中以Ａ（黄瓜→套种油菜或蒜苗→番茄→平菇）、Ｂ（黄瓜→套种油菜或蒜苗→黄瓜→番茄→蒜苗）两种效益最高，平均年产鲜菜每公顷分别为４９４ｔ和４０５ｔ，年纯收入分别为５３万元和５４万元。适于北方地区推广。

Experiments were conducted to compare four planting patterns in three kinds of solar greenhouses. The results showed that even in the coldest January the temperature in the three kinds of greenhouses was over 4℃. For the four planting patterns,the A type:Cucumber+intercropping non-heading Chinese cabbage or garlic sprouts→tomato→mushroom,and the B type:Cucumber+intercropping non-heading Chinese cabbage or garlic sprouts→cucumber→tomato→garlic sprouts produced the highest profits. The average fresh vegetable production reached 494t/ha and 405t/ha with net income at 530 000 and 540 000 yuan RMB,respectively. Thus the two planting patterns had high values for extension in north China.
