不同连作和轮作年限对加工番茄产量的影响

Effects of Different Continuous Cropping and Rotation Years on Yield of Processing Tomato

以加工番茄里格尔87-5为试验材料,采用田间分区试验方法研究不同连作和轮作年限下加工番茄的生长发育状况、病害发生及产量、交售等级等情况。结果表明:随着加工番茄连作年限的增加,其病害发生、农药使用成本、烂果率都随之增加,果实单果质量、产量及交售等级随之降低;轮作技术可有效缓解连作障碍,轮作年限越长,其作用效果越显著。

Selecting processing tomato cultivars Liger87-5 as material, growth conditions, diseases, yield and sell rating of processing tomato under different continuous cropping and rotation years were studied with the method of field partition. The results showed that the diseases, costs of pesticide, the rate of rotten fruit of processing tomato had a increasing trend and single fruit weight, yield, sell ratings had a descending trend with the extensions of continuous cropping years; crop rotation technology could alleviate continuous cropping barrier effectively, and its effects increased with rotation years.
