摘要
为了改善甘肃中部地区旱砂地籽瓜连作障碍,提高土地利用率及产出率,在甘肃省靖远县旱砂地选取了3种花生间作密度(株距40、50、60 cm)进行籽瓜/花生间作模式研究,通过对间作模式下籽瓜和花生生长发育、产量和经济效益分析,探究该间作模式的可行性及花生适宜间作密度。结果表明:间作花生后,籽瓜的成熟期提前,全生育期缩短,种子的千粒重显著提高,单瓜质量和可溶性固形物含量显著下降,对其他指标无显著影响;3种花生间作密度下,与单作籽瓜经济效益相比,1 hm2经济收入分别提高6.1%、16.3%和2.3%,增加收入1 064元、2 487元和395元,经济效益明显。旱砂地籽瓜/花生间作模式具有可行性,适宜的花生间作密度为株距50 cm。
In order to improve the continuous cropping obstacle of seed watermelon in dry sandy land in central region of Gansu,to make full use of the land and resources of light and heat and improve the utilization and yield,3 intercropping density（plant spacing is 40 cm,50 cm and 60 cm）were used in the dry sandy land in Jingyuan county of Gansu province. The growth,yield and economic benefits of seed watermelon and peanut under the conditions of intercropping model were analyzed to explored the feasibility of seed watermelon intercropping with peanut and the appropriate intercropping density. The results showed that the seed watermelon＇s mature period was advanced and the whole growth period was shortened,the thousand seed weight increased significantly,average fruit weight and soluble solids content reduced significantly,other indicators were less influenced. Compared the economic benefits with no intercropping,the income of per hm^2 increased 6.1%,16.3% and 2.3%,increase the income of 1 064 Yuan,2 847 Yuan and 395 Yuan,the economic benefits increased obviously. The mode of seed watermelon and peanut by intercropping in dry sandy land is feasible and the suitable peanut intercropping density is plant spacing 50 cm.
