整枝方式对番茄冠层特征及产量的影响

Impacts of different pruning modes on canopy characteristics and yield of tomatoes

以单杆整枝、双杆整枝、改良单杆整枝、连续换头整枝4种方式对番茄进行整枝处理,研究不同整枝方式对冠层及产量的影响.结果表明,单杆整枝方式有利于株高、茎粗生长;前期双杆整枝处理番茄产量最高,单杆整枝产量最低,盛果期双杆整枝和连续换头整枝叶面积指数大,叶倾角和散射辐射透过系数小,产量较高;叶面积指数与产量呈正相关,平均叶倾角、散射辐射透过系数与产量呈负相关.

With the different pruning modes of single pole, double pole, reform single pole and continuous removable boughs deal with the Lycopersicum esculentum Mill.This paper will study the influence on canopy characteristics and the yield. The result showed that, the pruning by single pole is beneficial for the plant high and stem diameter. The yield of Lycopersicum esculentum Mill.by double pole pruning is the most and in single pole pruning is the lowest in the early stage of the growth.In the full productive age, double pole pruning and continuous removable boughs pruning have higher leaf area index, little average leaf angle and scattered radiation through the coefficient. Besides, they have higher yield. Leaf area index and yield were positively correlated, and the average leaf angle, scattering radiation through the coefficient were negative correlation with the yield.
