试验利用免耕轻耙进行有机水稻生产,研究稻鸭共作有机水稻产量构成因素与产量间关系,指出有机栽培水稻产量主要由每穴穗数、每穗粒数、整株蛋白含量以及株高4个性状决定.稻鸭共作在每穴穗数增加的基础上,每穗粒数也增加显著,并随鸭群体量增加而增加,而整株蛋白质含量的增加也从生理角度上说明了稻鸭共作氮肥利用的增加.说明稻鸭共作,鸭排泄物可以增加稻田肥力,同时鸭在稻田内活动也可以增加肥料利用率,从而提高生物产量和经济产量.
試驗利用免耕輕耙進行有機水稻生產,研究稻鴨共作有機水稻產量構成因素與產量間關繫,指齣有機栽培水稻產量主要由每穴穗數、每穗粒數、整株蛋白含量以及株高4箇性狀決定.稻鴨共作在每穴穗數增加的基礎上,每穗粒數也增加顯著,併隨鴨群體量增加而增加,而整株蛋白質含量的增加也從生理角度上說明瞭稻鴨共作氮肥利用的增加.說明稻鴨共作,鴨排洩物可以增加稻田肥力,同時鴨在稻田內活動也可以增加肥料利用率,從而提高生物產量和經濟產量.

The experiment was carried out to study the relationship between the rice yield components and the yield in the organic rice production environment of integrated rice-duck farming,adopted no-tillage and light harrow technology.The results revealed that the yield of organic cultivation rice was mainly determined by the following four Characters:panicles per hill,grains per panicle,proteinlevel of the whole plant and plant height.In the integrated rice-duck farming system,grains per paniclewas significantly increased,as panicles per hill increased and duck population increased.The increase of whole plant protein level also physiologically demonstrated that nitrogen utilization efficiency was raised.In the system,the duck excrement could improve soil fertility,meanwhile,the fertilizer use efficiency was increased by the duck activities in the paddy,thus biomass and economic yield of rice improved.
