为了提高甜椒的座果率,1993年笔者根据甜椒的生长习性,通过打内膛枝,进行杯型整枝试验,取得了一定成效。据试验,整枝的平均单株座果为9.05个,单株平均产果量为1.35公斤,且果实整齐均匀;而未整枝的平均单株座果仅为2.9个,单株平均产量0.55公斤,且果实不整齐,品质差,同时整枝比不整枝的增产146%。据调查,整枝增产的原因:一是控制了营养生长,促进生殖生长;二是通风透光好,田间湿度易于降低,病害轻,坏叶烂果及落花落果少,果实品质高;三是有效地减少农药用量,降低生产成本。
In order to improve the fruit rate of sweet pepper, in 1993, the author according to the growth habit of sweet pepper, by playing briquettes, cup-type pruning test, and achieved some success. According to the test, the average number of fruit per unit for the pruning was 9.05, and the average fruit yield per plant was 1.35 kg and the fruit was neat and uniform. The average number of per unit fruit for unprotecting was 2.9 and the average yield per plant was 0.55 kg. And the fruit is not neat, poor quality, at the same time pruning than non-pruning yield 146%. According to the survey, the reasons for pruning increase: First, the control of vegetative growth and promote reproductive growth; Second, good ventilation, the field is easy to reduce the humidity, disease light, rotten and bad leaves and flowers, fruit quality is high; the third is effective To reduce the amount of pesticides and reduce production costs.
