摘要
为了解决同一大棚里连续种植青椒几年后出现的减产问题,对以改善棚内青椒生态环境为目的而组装的集成技术设施棚与采用常规技术棚进行了大区互比试验,并于试验区内同一条件下对棚膜透光、棚温变化、浇水与土壤含水量、棚内气流、施肥量、病虫害发生以及青椒长势和产量进行了定点调查。结果显示:设施集成技术棚较采用常规技术棚(对照)的生态环境有明显改善;青椒长势明显整齐;单株增加精品果产量和结果数达到显著与极显著水平,增产33%。经过比较后认为,目前简易大棚青椒生产上出现的减产问题是生态环境不良所致。试验的设施集成技术棚为解决现存问题提供了可能。
To overcome the reduction of output caused by several years＇ continuous green pepper planting in the greenhouse sheds, a comparative experiment was conducted in facility shed, on purpose to improve ecological environment for green pepper cultivation. In the experiment, shed light transmittance, shed temperature variance, irrigation rate and soil moisture level, shed airflow, fertilization rate, occurrence of insects and diseases, growth vigor and output of green pepper were investigated. The results showed that, the ecological environment in the facility shed was remarkably improved than that of the normal shed; in the facility shed the growth vigor was significant even; per plant fine quality fruit number and total fruit number were big or even significantly big and unit land area output increased 33%. The comparison concluded that the production reduction was caused by inferior ecological environment, and the problem was possible to be overcome through technology application of the facility shed.
