| 摘 要： | 为探明保水剂施用后对耐旱品种矮抗58生长及光合作用等的作用特征,通过大田试验,测定了保水剂不同用量(0,30,60,90 kg/hm2)的土壤水分、株高、叶面积、叶片相对含水量及光合特征等.结果表明:保水剂不但提高了各生育期表层土壤含水量,而且促进了20 cm以下土层土壤水分的提高.在拔节期,随保水剂用量的增加.叶片相...

| Abstract: | In order to investigate the characteristics of growth and photosynthetic parameters of winter wheat Aikang-58,a field trial was carried out to study the effect of water-retaining agent(0,30,60,90 kg/hm2) on soil moisture,height,leaf area,leaf water potential and photosynthetic characteristics.The results indicated that moisture increased not only in top soil,but also in 20 cm deep soil after application of water-retaining agent.At jointing stage,the leaf relative water content increased with the addition of... |
