水稻栽培新途径稻克草技术栽培措施的多因素分析

A NEW WAY TO PADDY CULTIVATION MULTI FACTOR ANALYSIS OF THE CULTIVATION MEASURES OF THE TECHNIQUE OF PADDY CONQUERING WEEDS

证实以高产优质高效为目的的水稻栽培新途径稻克草技术的科学性，优选出稻克草栽培技术的主要技术措施．对常规水稻栽培的行株距、穴苗数、施肥法、除草情况和水稻品种进行多因素多水平正交试验．得出了稻克草栽培技术措施的最佳组合和科学性，并在多重复对比试验中得到验证．稻克草技术一方面加强了土壤供肥和提高肥效，缓和草与稻争肥矛盾；另一方面发挥水稻个体生长优势，使稻田杂草处于劣势，同时缓和水稻种内竞争，水稻与杂草生长竞争的矛盾向有利于水稻生长方面转化，促使水稻获得更高产。

The science of the technique of paddy conquering weeds ,a new way to paddy cultivation for the purpoes of high yield, high superior quality and high efficiency is confirmed. The optimum seeking of the main technical measures of the cultivation technique of paddy conquering weeds is done. The multi factor, multi level crossing experiment of the plant row spacing,the number of the plants in each hloe, the methods of spreading manure, the weeding condition and the variety of paddy is carried out. The optimum combination and the science of the trechnical measures of the repeated contrast experiments. The technique of paddy conquering weeds can, on the other hand, make the soil adequately provide with manure, raise the efficiency of the manure and mitigate the contradiction of fighting for manure between paddy and weeds; on the other hand, this technique can give play to superiority the individual growing of paddy, make the weeds in the paddy field be reduced to inferiority and relax competition transform into the benefit for the paddy growing and impelling the paddy to grow better.
