摘  要：
对简易大棚种植青椒出现的减产问题,进行了定点跟踪调查。结果表明,棚体脊高2 m,边高0.9 m;施各种化肥4 147.5 kg/hm2,未腐熟鸡粪75 m3/hm2;浇水10次(灌满畦子);活土层土壤20 cm;棚内光照6.5万lx,较棚外光照减少34%;棚内50 cm高处温度为34℃以上达7 h;棚边风速较棚中风速提高24%;在生长周期中病虫害未能得到有效控制,这样的生态环境条件,致使青椒个体生长过旺,群体生长极不整齐,挂果偏少,非生理性畸形果增多,部分植株根系形成侧根。生态环境不良是简易大棚产量下降的根本原因。

摘  要：
For the problems of the yield reducing of green pepper in simple plastic shed,the set-point tracking investigation was taken.The shed body: ridge hight 2 m,side hight 0.9 m.Fertilizer application 41 475.5 kg/hm2,not rotten chicken manure 75 m3/hm2;Watering: 10 times surface flooding;Soil in active layer: 20 cm;Lighting inside shed: 6 5000 lx,reduced by 34% than the light outside.In the 50 cm high position of the shed,the temperature over 34 ℃ can last for 7 hs;wind speed in the side of the shed is increased by 24% than that in the middle.In the growth period,the diseases and insect pests were not effectively controlled.The reslutls showed that,under this ecological environment,single green pepper overgrew,group green pepper grew in disorder,fruit was less,unphysically deformity fruit increased,and part of the plant root system formed the lateral root.So the bad ecological environment of simple plastic shed is key cause of the decline in yield.
