采用盆栽试验，在不施磷和施磷条件下，对广东省广泛种植的18个甜糯玉米品种进行比较研究，旨在筛选耐低磷的甜糯玉米品种，合理布局甜糯玉米种植，提高土壤中磷利用效率。结果表明：不同基因型甜糯玉米耐低磷能力存在明显的差异，根冠比、根干重、冠干重和植物磷积累量可作为甜糯玉米耐低磷筛选的重要指标。初步筛选出3个耐低磷甜糯玉米品种花糯一号、孺子牛269号和红帅。
採用盆栽試驗，在不施燐和施燐條件下，對廣東省廣汎種植的18箇甜糯玉米品種進行比較研究，旨在篩選耐低燐的甜糯玉米品種，閤理佈跼甜糯玉米種植，提高土壤中燐利用效率。結果錶明：不同基因型甜糯玉米耐低燐能力存在明顯的差異，根冠比、根榦重、冠榦重和植物燐積纍量可作為甜糯玉米耐低燐篩選的重要指標。初步篩選齣3箇耐低燐甜糯玉米品種花糯一號、孺子牛269號和紅帥。

Under the non-phosphorus and high phosphorus levels, a comparative study of 18 sweet waxy maize genotypes widely planted in Guangdong province was carried out by using pot experiment, aiming to screen sweet glutinous corn genotypes of resisting to phosphorus, for the rational distribution of sweet glutinous corn varieties, improving soil phosphorus utilization and providing experimental evidence. The results showed that there are obvious genotypes differences of different varieties of sweet corn in low phosphate endurance. Root-shoot ratio, root dry weight, coronal dry weight and accumulation of phosphorus were suggested as screening indicators of sweet maize on tolerance to low-phosphorus stress. The experimental results preliminary screened three phosphorus-resistant genotypes of sweet corn, namely the Huanuo NO.1, Ruziniu No.269 and Hongshuai.
