摘要:
以籽用葫芦“瑞丰9号”为试材，设置0、112.5、225.0、337.5 kg·hm-2 4个施磷水平（分别为P0、P1、P2、P3）的田间试验，研究不同施磷水平对籽用葫芦干物质和磷素吸收积累、产量的影响，以期为籽用葫芦大田生产的磷肥施用量提供参考依据。结果表明：与P0相比，施用磷肥能够促进籽用葫芦各器官和整株对磷素的吸收、积累和干物质的积累，以P2处理最高，成熟期整株干物质和磷素吸收积累量分别较P0增加19.5%、23.0%；施磷量的增加能够增加产量，但过量的施肥产量反而降低，尤以P2处理最高，达到2 079 kg·hm-2，较P0增产27.5%。籽用葫芦磷肥的施用要注重果实膨大期和成熟期的供应，结合籽用葫芦产量、磷素吸收和积累特种以及干物质的变化，在该试验同等肥力和栽培环境的条件下，磷肥施用量为112.5~225.0 kg·hm-2。
Abstract:
Seed-calabash ‘Ruifeng No.9’ was used as the test material,applying four rates of P fertilizer,0,112.5,225.0,337.5 kg·hm-2(P0,P1,P2,P3),respectively,the effects of P fertilization on dry matter accumulation(DMA),P uptake and accumulation(PUA) and synthesized economic yield of seed-calabash was investigated,in order to provide a theoretical basis for the amount of phosphate fertilizer in the field of seed-calabash.The results showed that P application increased dry matter accumulation,uptake and accumulation of seed-calabash for 225.0 kg·hm-2 treatment,increasing by 19.5%,23.0% compared with no P fertilizer treatment at fruiting stage.The increase in the amount of phosphorus could increase the yield,but the overdose of fertilization could decrease yield.The highest yield of processing 225.0 kg·hm-2 treatments was 2 079 kg·hm-2 respectively.Compared with no P fertilizer treatment,seed-calabash of 225.0 kg·hm-2 treatments increased by 27.5%.Based on synthesized economic yield and P fertilizer efficiency,the recommendation of P fertilizer for seeds with a gourd was 112.5-225.0 kg·hm-2 under the climatic condition of the experimental area.
