Effect of different types of flame guns on the weeding and insect control effects of Chinese cabbage
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 2 169 yuan,the benefit increased by 2 176 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.
