摘要
本文通过对几种作物不同种植比例混播的定位试验及室内测定分析,证明粮豆等不同作物混播,既有一定的培肥改土作用,又有明显的生物互作效应。据试验资料表明,混播不仅当季作物比单播增产9.0～32.0％,还能使后茬作物增产7.8～10.1％,同时,对抑制田间病虫草的危害也有一定的作用。提出粮豆混作技术,在区内生产条件不高的情况下,只要粮、油、豆等作物搭配合理,混播比例适宜,仍是我区农业生产中一条行之有效的增产措施。
The result of this experiment showed that the interplanting of spring barley(Hodeum sativum Jess.)or wheat (Triticum aestivum L.)with pea(Pisum spp)or broad bean(Vicia faba L.)in certain proportion not only fertilized soil,but also had biological mutual effect obviously.The output of the cultivating form increased by 9 to 32 percent per ha compared with sowing barley or wheat only.And, the next yield in the field which harvesteb both grain and bean last year also increased by 7.8 to 10.1 percent per ha. Moreover,it could control the harm of insect,diseases and weeds. Therefore, so long as getting the planting proportion properly this traditional cultivating form might still take advantage in agricultural production in the poor area in Tibet.
