我国甜椒因设施内栽培技术难度大,产量低而不稳,设施甜椒平均产量仅为3 000 kg/667 m2左右,而荷兰等先进国家甜椒产量为15 000 kg/667 m2左右,我国设施甜椒产量仅及发达国家的1/5。即使在引进国外大型温室中,引用国外甜椒生产技术, 其产量也有较大差距,严重影响了温室生产效益 The sweet pepper in our country is hard to be cultivated in the facility and its output is low and unstable. The average output of the sweet pepper in the facility is only about 3 000 kg / 667 m2, while that in the Netherlands and other advanced countries is about 15 000 kg / 667 m2. Facilities Bell pepper output only 1/5 of the developed countries. Even in the introduction of large-scale greenhouse in foreign countries, the introduction of foreign sweet pepper production technology, the output is also a big gap, seriously affecting the greenhouse production efficiency
