目前大棚生产中存在的主要问题之一,是利用率低,多数只种一茬,少数种植两茬,如只种一茬平均亩产值约6000元左右,种两茬亩产值可达8000元左右,几年来我们通过实验、示范,大棚一年二茬半至三茬栽培,亩产值可达万元以上。 大棚内进行蔬菜多品种、多茬次栽培,不但增加了蔬菜种类,使蔬菜分期上市,能增加收入,对调剂市场、丰富菜篮子有重要意义。 At present, one of the major problems existing in the production of greenhouses is the low utilization rate. Most are only one crop. Only a few crops are planted with two crops. For example, the average output value per mu is only about 6,000 yuan. Over the past few years, we passed experiments, demonstrations, greenhouses for two to three quarters of crop cultivation a year, the mu output value of up to million. Many varieties of vegetables in the greenhouse, planting more stubs, not only increased the type of vegetables, vegetables market, can increase revenue, the swap market, rich basket of great significance.
