作者段文学,张海燕,解备涛,王庆美,汪宝卿,张立明(2019)在《有机多肽酶活性促进剂施用方式对鲜食型甘薯干物质积累分配、产量及品质的影响》一文中研究指出:为探究有机多肽酶活性促进剂对鲜食型甘薯产量和品质的调控效应,在大田条件下,以鲜食型甘薯品种龙薯9号和苏薯8号为供试材料,每个品种设置全生育期不喷施有机多肽酶活性促进剂(CK)、有机多肽酶活性促进剂栽插前蘸根+栽后40 d叶面喷施(P1)和有机多肽酶活性促进剂栽插时灌根+栽后40 d叶面喷施(P2) 3个处理,研究其对鲜食型品种干物质积累分配、产量及品质的影响。结果表明,2个品种的P1和P2处理生长中后期叶片的磷酸蔗糖合成酶(SPS)活性、蔗糖含量、收获期植株总干重和块根干重均显著高于CK。龙薯9号各处理收获期的侧枝茎和块根干物质分配比例均无显著差异,P1和P2处理的主茎下部叶、主茎下部茎干物质分配比例均显著低于CK;苏薯8号P2处理的主茎下部叶、主茎下部茎、侧枝茎和侧枝生长点干物质分配比例均显著低于CK和P1处理,块根干物质分配比例显著高于CK和P1,分别提高8. 98%和6. 23%。龙薯9号P2处理收获期块根可溶性糖含量与P1无显著差异,但显著低于CK,降低5. 22%,P2处理的块根淀粉含量显著高于CK和P1,分别提高18. 76%和9. 23%,干率与P1处理无显著差异,但均显著高于CK,分别提高4. 56%和5. 71%;苏薯8号块根的可溶性糖含量各处理无显著差异,且P2处理的块根淀粉含量和干率与P1均无显著差异,但显著高于CK,其中淀粉含量提高6. 13%,干率提高4. 51%。2个品种P2处理的块根产量均显著高于CK和P1,其中龙薯9号分别提高30. 46%和14. 42%,苏薯8号分别提高27. 72%和11. 69%。综上,施用有机多肽酶活性促进剂有利于提高鲜食型品种块根产量和淀粉含量,其中P2处理增产幅度最高,其对可溶性糖含量的调控存在品种间差异。本研究为鲜食型甘薯提质增效和生态种植技术提供了理论依据。
