摘要
针对黑龙江省花生栽培技术落后,生产水平低等问题,研究了不同种植方式对花生生育及产量的影响。研究结果表明,花生大垄双行栽培模式的适宜密度为40株.m-2,比密度32株.m-2的处理增产14.7%,两种密度处理的花生产量在1%水平上差异显著;花生小垄单行栽培模式的适宜密度为30株.m-2,比密度26株.m-2的处理增产8.4%,两种密度处理的花生产量没有显著差异;花生大垄双行栽培模式(密度为40株.m-2)的产量比花生小垄单行栽培模式(密度为30株.m-2)增产37.5%,两种模式处理的花生产量在1%水平上差异显著。应用本项研究取得的成果,集成组装了寒地花生大垄双行高产栽培模式,对推动黑龙江省花生生产的发展具有重要意义。
The experiment was made on the growth and development and yield of peanut under the influence of different planting patterns to cope with the backward of the cultivation technique and the lower level of productivity in Heilongjiang province. The results showed the reasonable density was 40 plants per square meter for the cultivating pattern of double rows of the wide ridge. Its yield was 14.7 percent more than the treatment of 32 plants per square meter. The difference of their yield was significant at the level of 1 percent. The reasonable density was 30 plants per square meter for the cultivating pattern of single row of the narrow ridge. Its yield was 8.4 percent more than that of the treatment of 26 plants per square meter. The difference of the yield of two densities was not significant. The yield for cultivating pattern of double rows of the wide ridge was 37. 5 percent more than that of the cultivating pattern of single row of the narrow ridge. The difference of the yield between the two cultivating patterns was significant at the level of 1 percent. The cultivating model of double rows of the wide ridge was integrated for the peanut planted in cold district. It was meaningful for Heilongjiang province to accelerate the peanut production.
