Suitable Training Method under Low Plastic Film Greenhouse Cultivation on Sweet Pepper (Capsicum annuum 'Special') in Highland

摘要

This study was conducted to evaluate the suitable training method under low plastic film greenhouse cultivation on sweet pepper in highland. Training treatments were upright training, inclination training, upright => inclination training (Jun. 8), andupright => inclination training (Aug. 21). hi the early growth stage, lateral shoots of plants of inclination training treatments were strong and higher than those of others. Light transmission ratio of upright training around low leaves was 37% which was higher than 14% of inclination training. The fruit setting ratio of upright training was the highest by 41% out of all. The number of fruits per plant of the upright training was 18.1, which showed 5.2 more than that at inclination training. The marketable yield of the upright training was 109 ton-ha~(-1) ; which showed 43% higher than inclination training. Labor time of inclination training was 7,785 hr-ha~(-1), which showed 1,185 hr-ha~(-1) more than that of upright training. Therefore, the uprighttraining was recommended for the suitable training method to marketable yield and quality improvement under low plastic film greenhouse cultivation on sweet pepper in highland.
