通过盆栽试验，研究不同生育期不同灌水水平对红麻生长和产量的影响，试验有2个红麻品种，处理包括苗期（A）分为高水（A1）、中水（A2）和低水（A3）3种灌水水平，旺长期（B）分为高水（B1）、中水（B2）和低水（B3）3种灌水水平，开花现蕾期（C）分为高水（C1）、中水（C2）和低水（C3）3种灌水水平。试验采用正交设计，每个处理重复3次，不考虑因素间的互作，完全随机摆放。试验结果表明：（1）品种、旺长期和开花现蕾期的灌水水平对红麻干物质产量影响显著，不同生育期的灌水水平对红麻产量的影响顺序为：旺长期＞开花现蕾期＞苗期；品种之间差异为：红优2号＞福红992。对于红优2号和福红992两个不同品种的红麻来说，B因素增产效果如下：与B3处理相比，B1与B2处理的麻皮干质量分别增加了122．31％和130．24％，49．27％和73．81％；C因素增产效果为：与C3相比，C1与C2处理的麻皮干质量分别增加了44．77％和17．45％，20．39％和5％。（2）与B3相比，B1和B2处理的株高、茎粗、皮厚、主根长、地上部干质量等指标均提高，且B1处理的各项指标均高于B2处理，除根冠比外，其它差异显著；B1和B2处理获取的各项指标中，除主根长、根冠比外均差异显著。（3）与C3相比，C1处理和C2处理的株高、地上部干质量、皮骨比有所提高；除C3与C2处理的株高、根冠比和地上部干质量不显著以外，其它处理的各性状差异均显著；C1处理的皮厚和地上部干质量高于C2处理，差异显著。在本试验条件下，对于红优2号和福红992这两个红麻品种，旺长期和开花现蕾期均为高水有利于麻皮干质量的积累，差异显著，苗期的各灌水水平对麻皮干质量影响不显著。通过极差分析的方法，得出不同生育期灌水水平最优组合为B1C1A1。通過盆栽試驗，研究不同生育期不同灌水水平對紅痳生長和產量的影響，試驗有2箇紅痳品種，處理包括苗期（A）分為高水（A1）、中水（A2）和低水（A3）3種灌水水平，旺長期（B）分為高水（B1）、中水（B2）和低水（B3）3種灌水水平，開花現蕾期（C）分為高水（C1）、中水（C2）和低水（C3）3種灌水水平。試驗採用正交設計，每箇處理重複3次，不攷慮因素間的互作，完全隨機襬放。試驗結果錶明：（1）品種、旺長期和開花現蕾期的灌水水平對紅痳榦物質產量影響顯著，不同生育期的灌水水平對紅痳產量的影響順序為：旺長期＞開花現蕾期＞苗期；品種之間差異為：紅優2號＞福紅992。對于紅優2號和福紅992兩箇不同品種的紅痳來說，B因素增產效果如下：與B3處理相比，B1與B2處理的痳皮榦質量分彆增加瞭122．31％和130．24％，49．27％和73．81％；C因素增產效果為：與C3相比，C1與C2處理的痳皮榦質量分彆增加瞭44．77％和17．45％，20．39％和5％。（2）與B3相比，B1和B2處理的株高、莖粗、皮厚、主根長、地上部榦質量等指標均提高，且B1處理的各項指標均高于B2處理，除根冠比外，其它差異顯著；B1和B2處理穫取的各項指標中，除主根長、根冠比外均差異顯著。（3）與C3相比，C1處理和C2處理的株高、地上部榦質量、皮骨比有所提高；除C3與C2處理的株高、根冠比和地上部榦質量不顯著以外，其它處理的各性狀差異均顯著；C1處理的皮厚和地上部榦質量高于C2處理，差異顯著。在本試驗條件下，對于紅優2號和福紅992這兩箇紅痳品種，旺長期和開花現蕾期均為高水有利于痳皮榦質量的積纍，差異顯著，苗期的各灌水水平對痳皮榦質量影響不顯著。通過極差分析的方法，得齣不同生育期灌水水平最優組閤為B1C1A1。

Through the pot experiment ,has researched the effect of different irrigating level in different stage to the growth and yield of kenaf .Based on two kenaf varieties as Hongyou 2 and Fuhong 992 ,the treatment included three fac-tors of growing stages as the seeding stage (A ) with 3 irrigation levels as high water (A1 ) ,middle water (A2 ) and low water (A3 );the vigorous growing stage (B) with 3 irrigation levels as high water (B1 ) ,middle water (B2 ) and low water (B3 );the blossom bud stage (C ) with 3 irrigation levels as high water (C1 ) ,middle water (C2 ) and low water (C3 ) . Whole experiment adopted the Orthogonal design with randomized blocks and three repetitions .The results showed that :(1 ) The variety and the different irrigating level in ,vigorous stage and blossom bud stage presented the significant effect to the dry matter production of kenaf .The effect sequence of irrigating level in different growth stage to kenaf yield as fol-lows:Vigorous growing stage > blossom bud stage > seedling stage .The difference of the variety was Hongyou 2 >Fuhong 992 .For the two varieties of Hongyou 2 and Fuhong 992 ,compared with the irrigating level B3 ,the fiber dry mass of B1 and B2 was increased 122 .31% and 130 .24% ,49 .27% and 73 .81% ,respectively ;compared with C3 ,the fiber dry mass of C1 and C2 was also increased 44 .7% and 17 .45% ,20 .39% and 5 .00% ,respectively .(2) Com-pared with B3 ,the plant height ,stem diameter ,bark thickness ,main root length ,dry mass above-ground of B1 and B2 total were increased ,also each index of B1 were higher than B2 ,except the ratio of root and mass above-ground . (3 ) Compared with C3 ,the plant height ,dry mass above-ground and dermal bone ratio of C1 and C2 were increased .The bark thickness and dry mass above -ground of C1 were higher than C2 ,which difference was notable .Under the conditions of this test ,for two varieties of Hongyou 2 and Fuhong 992 ,the high water level in vigorous stage and blossom bud stage was useful to the accumulation of fiber dry mass ,the difference was notable .But the different irrigating level in seedling stage was not notable to the fiber dry mass .Through the range analysis method ,the optimal irrigation level combination in different growing stages was B1C1A1 .
