江苏沿海地区青贮玉米抗倒伏栽培与加工利用技术OA

This paper reviewed the lodging-resistant cultivation and processing utilization technologies of silage maize in the coastal area of Jiangsu Province.In terms of variety selection and sowing,varieties with strong stress resistance and lodging resistance,such as Lidan 638 and Beinong Silage 308,are recommended.Sowing is carried out in an east-west orientation with a wide-narrow row cross configuration,and the sowing rate is 22.5-30.0 kg/hm².Regarding field management,sufficient basal fertilizer is applied,with reasonable topdressing and intertillage earthing-up conducted at the jointing stage and the large bell stage.Plant growth regulators such as Yuhuangjin are sprayed after the jointing stage.Post-lodging management is implemented according to the lodging type:slightly lodged plants are left untouched;severely root-lodged plants are straightened and earthed up within 3 days;laterally bent plants are gently lifted to remove standing water;stem-broken plants are harvested early and replaced with leafy vegetables.Disease and pest control is achieved through agricultural measures(e.g.,selection of highly resistant varieties),biological control(e.g.,utilization of natural enemies),and chemical control(e.g.,using anilazine for disease control and abamectin for pest control).For harvesting and silage production,mechanical harvesting is carried out from the milky stage to the dough stage using either direct harvesting or two-stage harvesting methods.After harvest,processing and utilization are performed via two methods:baling and wrapping silage,and pit silage.This paper provides a reference for efficient cultivation and utilization of silage maize.
