摘要
研究里下河地区稻套麦不同共生期及播种量对稻田套小麦群体质量及产量的影响,结果表明:共生期6 d、播种量为210 kg/hm2条件下,易获得较高的群体质量和产量;共生期超过6 d,群体质量会有所下降;播种量过低,会造成基本苗少,成穗数减少,不易获得高产。
The effect of the symbiotic period and seeding rate in rice field on population quality and yield of wheat in Lixiahe area were studied. The results showed that under the conditions of symbiotic period of six days ,seeding rate of 210 kg/hm^2,it was easy to obtain high population quality and yield.The symbiotic period was more than 6 days ,population quality would decreased ,seeding rate was too low.It could cause the basic seedling to reduce ear number decrease,not easy to get high yield.
