我县常年种植花生27万亩以上,其中沙地占26万亩。由于沙地土壤瘠薄,保水、保肥能力低,加之一些品种适应性差,且退化严重,致使产量低而不稳。为了改变沙地花生低产面貌,我们着重从品种方面入手,大量引入和培育适合沙地种植的优良品种,经过几年的试验、示范,筛选出了适合我县沙地种植的六个优良品种。这些品种在我县沙地种植产量基本稳定,一般亩产都在150公斤以上。
I perennial 27 million mu of peanut cultivation, of which 26 million mu of sand. Due to infertile soils in sandy soils, water retention and low fertilizer-holding capacity, coupled with the poor adaptability of some varieties and the serious degradation, the yield is low and unstable. In order to change the low-yielding peanut landscape in Saudi Arabia, we focused on cultivating and cultivating fine varieties suitable for sandy land cultivation. After years of experiments, we demonstrated and selected six fine varieties suitable for sandy land cultivation in our county. The output of these varieties in the sandy areas of our county is basically stable, with average yields of more than 150 kg per mu.
