The invention relates to an unmanned aerial vehicle direct seeding technology for terraced field rice, in particular to a rice cultivation technology for directly seeding rice seeds by an unmanned aerial vehicle without seedling raising, seedling pulling, seedling washing and seedling transplanting, which comprises the following steps of: turning and burying straws and weeds to return to the field by using a micro tillage machine; the moisture surface is flat, clean, free of residues and weeds and moderate in hardness, and furrowing is performed; the method comprises the following steps: selecting a high-quality high-yield rice variety with strong disease resistance and stress resistance, soaking seeds in water with a bactericide, and spreading and airing the soaked seeds until seed epidermis becomes white for later use; the direct seeding rice is 7-10 days later than the transplanted rice, and the seeds are directly sown on the furrow surface by using the unmanned aerial vehicle; managing water according to the principles of wet seedling emergence, shallow water tillering, repeated light placement and field irrigation, strictly preventing moisture surface water accumulation, and performing field conventional management according to rice after seedling emergence until the rice is mature and harvested. Rice seeds are directly sown in the terraced field through the unmanned aerial vehicle, the procedures of seedling scattering, seedling pulling, seedling washing, seedling picking, seedling transplanting and the like are omitted, the production efficiency is improved, and the labor intensity and the production cost are reduced.
本发明是一种梯田水稻无人机直播技术,是以无人机直接播种水稻种子免育秧拨秧、洗秧和插秧的水稻栽培技术,其步骤为:用微型耕整机进行秸秆和杂草翻埋还田;做到墒面平整,墒面洁净,无残荐、无杂草,墒面软硬适中,开出沟凼;选择优质高产抗病抗逆性强的水稻品种,用杀菌剂兑水浸种,浸种后进行摊晾到种子表皮发白待用;直播水稻较移栽水稻迟播7‑10天,利用无人机将种子直接播撒到墒面上;按照湿润出苗、浅水分蘖、多次轻搁、田间灌溉的原则管理水,严防墒面积水,出苗后按水稻的田间常规管理,直到水稻成熟收割。本发明用无人机直播水稻种子于梯田,免除撒秧拔秧洗秧挑秧和栽秧等工序,提高了生产效率,降低了劳动强度和生产成本。
