水稻精量旱穴直播示范高产栽培技术

水稻是重要的粮食作物,不仅可保障社会安稳,还可促进国民经济发展。现阶段,水稻种植技术主要分为移栽与直播两种方式。人工移栽费时费工、工作效率较低。机械化移栽是现阶段普遍采用的移栽方式,也是樊城区主要推广的方式,移栽面积持续增长。然而,机械化移栽仍然存在秧苗素质低、秧田操作不正确、育秧及栽插环节劳动强度大等缺陷。同时,农村劳动力持续降低,不管是手工移栽还是机械移栽,劳动力是其关键性因素。研究发现,水稻机械化直播技术具有节省劳动力、节省秧田等独特优势。对于此,文章以樊城区陈国兵的冬闲田为研究对象,应用华南农业大学陈锡文院士发明的精量旱穴直播机,开展杂交中稻直播示范,探索其高产栽培技术。

High Yield Cultivation Techniques of Rice by Intensive Dry Hole Direct Seeding

Rice is an important food for people,which can not only ensure social stability,but also promote the development of national economy.At present,rice planting technology is mainly divided into transplanting and direct seeding.Manual Transplanting is time-consuming and low efficiency.Mechanized transplanting is a commonly used transplanting method at this stage,and it is the main promotion method in Fancheng district.The transplanting area continues to grow.However,there are still some defects in mechanized transplanting,such as low quality of seedling,incorrect operation of seedling field,high labor intensity in seedling raising and transplanting.At the same time,the rural labor force continues to decrease,whether it is manual transplanting or mechanical transplanting,labor force is the key factor.It is found that the mechanized direct seeding technology of rice has the unique advantages of saving labor and rice seedling field.For this reason,this paper takes Chen Guobing's winter fallow field in Fancheng district as the research object,and uses the precise dry hole direct seeding machine invented by academician Chen Xiwen of South China Agricultural University to carry out the direct seeding demonstration of hybrid medium rice and explore its high-yield cultivation technology.
