Weed suppression and insect pest preventing type culture method of cowpea

Abstract

The invention discloses a weed suppression and insect pest preventing type culture method of cowpea. The method is that the weeds in a cowpea field is treated by suppression after sowing the cowpea; the weeds suppression includes that weed suppression liquid is sprayed to the cowpea field, and then the surface of the cowpea field is covered with a weed suppression mulching film and closed for 4 to 8 days. The method further comprises the steps of 1, preparing the land, namely, selecting the field which is 6 to 8 in pH and is used for planting non-leguminous plants in the past; tilling the soil until reaching the depth of 25 to 35cm 13 to 16 days before sowing the seeds; 2, performing field management, namely, regularly irrigating and topdressing the cowpea field subjected to weed suppression treatment. According to the method, the weed suppression mulching film covering the cowpea filed is manufactured from degradable material, rather than the general synthetic polymer, so that the organic substances in the soil can be increased, the fertilizer effect of the soil is improved, the plastic pollution can be reduced, and the soil structure cannot be damaged.

Description

technical field [0001] The invention relates to the field of plant cultivation, in particular to a cultivation method for suppressing weeds and preventing insects of cowpea. Background technique [0002] With the adjustment of the planting industry structure, the planting area of ​​cowpea has increased year by year, and the area, type and degree of harmful organisms in cowpea have also increased and aggravated accordingly. At present, the main technical measures for pest control of cowpea include agricultural control, chemical control, physical control, biological control, etc. Cowpea mainly has insect pests and weed damage during planting and growth, and weed damage mainly includes crabgrass, hemostatic crabgrass, hairy horse Tang, Qianjinzi and paspalum, etc., generally use pesticides to weed weeds, which cannot cure these weeds, and the pesticides used are not conducive to the growth of cowpea. If a long-term weed control program can be designed, it will be very important...
