水稻不同抛秧密度对比试验

A comparison experiment of different rice seedling-throwing densities

为了解决浦北县水稻单位面积有效穗数少的问题,找出当地水稻抛秧最佳密度,为高产栽培提供技术支撑和科学依据,于2013年对早造进行了不同抛秧密度试验。试验结果表明,每667m2抛2.4万蔸的处理产量最高、经济效益最好,可在当地早稻推广应用。

In order to solve the problem of less effective ears per unit surface of rice in Pubei, find the best suitable seedling-throwing density and provide scientific basis for high-yield cultivation technology, a comparison experiment of different rice seedling-throwing densities in early rice of 2013. The results show that the treatment of 24000 seedling/667m^2 has the highest yield and best economic benefit,which can be extended in local early rice production.
