水稻是我国的主要粮食作物之一,我国以世界水稻种植面积的21.4%获得了世界水稻34.5%的产量,为世界之最。但是我国的水稻种植机械化水平与世界发达国家相距甚远。我国水稻的主要种植模式为移栽,而抛秧栽培则是水稻移栽的一项新技术,是水稻栽培技术的一次创新和变革,被列为国家重点推广的农业实用新技术。抛秧栽培以抛栽替代了传统的插秧作业,大大减轻了劳动强度,提高了劳动效率,而且具有不伤根、返青快、低节位
Rice is one of the main grain crops in China. China has obtained 34.5% of the world’s rice output with 21.4% of the world’s rice acreage, which is the highest in the world. However, the level of mechanization of rice cultivation in our country is far from that of the developed countries in the world. The main planting mode of rice is transplanting in our country, and throwing seedling cultivation is a new technology of rice transplanting. It is an innovation and transformation of rice cultivation technology and is listed as a practical agricultural technology promoted by the state. Throwing seedling cultivation to throwing replaces the traditional planting operations, greatly reducing the labor intensity and improve labor efficiency, but also does not hurt the roots, rejuvenation fast, low node
