不同类型火焰枪对小白菜除草防虫效果的影响

Effect of different types of flame guns on the weeding and insect control effects of Chinese cabbage

为研究火焰枪除草防虫效果,应用单头火焰枪、十头火焰枪进行小白菜除草防虫试验,调查比较杂草、虫害、小白菜出苗与产量等。结果表明,火焰枪可烧死土表杂草种子,杂草数量有所减少,但间苗期间需配合人工除草,利于小白菜丰产稳产,可有效防治黄条跳甲发生,其中十头火焰枪比常规除草的小白菜667 m^(2)产量增加723 kg,产值增加2169元,效益增加2176元,比药剂除草产量增加58 kg,产值增加174元,成本增加710.7元,效益减少536.7元。综合表现较好,十头火焰枪除草处理配合防虫网覆盖避雨栽培可作为小白菜有机栽培的生产技术之一。

In order to study the weeding and insect control effect of the flame gun,a single-head flame gun and a ten-head flame gun were used to carry out the weeding and insect control test of Chinese cabbage,and weeds,insect pests,Chinese cabbage seedlings and yield were investigated and compared.The results showed that the flame gun could burn the weed seeds on the soil surface,and the number of weeds was reduced,which needed to be combined with manual weeding,and was conducive to the abundant and stable yield of Chinese cabbage,could effectively prevent and control the occurrence of Phyllotreta striolata.Compared with the conventional treated weeding cabbage,the yield of the ten-head flame gun treated Chinese cabbage increased by 723 kg,the output value increased by 2169 yuan,the benefit increased by 2176 yuan.Compared with the chemical treatment,the yield of the ten-head flame gun treated Chinese cabbage increased by 58 kg,the output value increased by 174 yuan,the cost increased by 710.7 yuan,and the benefit decreased by 536.7 yuan.The weeding treatment of ten-head flame gun combined with insect net covering and rainproof cultivation can be used as one of the production technologies of organic cultivation of Chinese cabbage.
