宁夏中部干旱地区西瓜保墒栽培模式的试验研究

从农业保墒措施和水利补灌技术措施出发,在宁夏同心县预旺镇南塬村进行西瓜的不同覆盖栽培方式和机械补水的试验研究,分析了不同覆盖方式在补灌条件下对西瓜生长发育、产量的影响,并对西瓜生理生育指标(株高、颈粗、叶面积、蔓长、产量等)进行了对比分析.经2 a试验观测的数据表明:不同覆盖材料对西瓜种子的萌发时间、出苗率、病害发生率、成熟时间、产量的影响不同,其中无色膜草覆盖方式在当地表现突出,节水节能的效果明显,提高了单位面积的净收益和农田水利用效率.

Experimental research on the method of dryland watermelons covered mode and soil moisture conservation of arid region in the middle area of Ningxia

Based on the idea of measures of preserving soil moisture and the supplementary irrigation technology,this paper studies watermelon cultivation of different coverages in Nanyuan village,Yuwang town,Tongxin county of Ningxia.Then it analyzes the impact of watermelon growth and development,output of the different coverage ways in supplementary irrigation and analyzes watermelon physiological indicators of fertility（height,thick neck,leaf area,the vine long,output and so on）.The statistical analysis of two year trial shows that the influence of coverage of different materials on the watermelon seeds germination time,the germination rate,the incidence of disease,mature,quality is different.The colorless film-grass coverage performs prominently in the local area in the locate,and has obvious effect of water-saving and energy conservation,and improves the net income per unit area and agricultural water using efficiency.
