摘要
采用田间小区试验方法,以施普通有机肥(OF)和当地习惯施肥(CK)为对照,研究了保护地施用生物有机肥(BOF)对西瓜生长、产量和品质的影响,旨在为当地保护地西瓜的高产优产提供依据。结果表明:施用生物有机肥明显促进了保护地西瓜的生长。结瓜期生物有机肥处理的主蔓长比普通有机肥和当地习惯施肥处理分别增加了10.9%和15.2%,SPAD值比普通有机肥处理和当地习惯施肥处理分别提高了9.9%和6.7%,结瓜部位比普通有机肥处理和当地习惯施肥处理分别提高了10.3 cm和14.5 cm,但是生物有机肥处理对西瓜的叶片数和茎粗没有显著影响。与普通有机肥和当地习惯施肥处理相比,施用生物有机肥显著提高了西瓜的结瓜个数和产量,结瓜个数比普通有机肥处理和当地习惯施肥处理分别增加7.6%和11.6%,产量分别提高了14.5%和17.9%,生物有机肥处理的产量达46 860 kg·hm-2,而普通有机肥处理对西瓜没有明显的增产效果。施用生物有机肥可提高西瓜的可溶性固形物(SSC)含量,降低西瓜的果皮厚度,但是与普通有机肥和当地习惯施肥处理差异均不显著(p>0.05)。
Aimed at providing basis for a high yield and good quality production of watermelon, the effect of biological organic fertilizer on watermelon growth, yield and quality under protected cuhivation conditions was studied in a field plot experiment with three treat- ments： biological organic fertilizer application （BOF）, organic fertilizer application （OF） and conventional fertilization （CK） . The results showed that BOF improved watermelon growth significantly. Compared with those of OF and CK, the main tendril in BOF in- creased 15.2% and 10. 9%, the SPAD value in BOF increased 9. 9% and 6. 7% , and the watermelon bearing position in BOF was increased 10. 3 cm and 14. 5 cm, respectively; however, BOF had no significant effect on leaf numbers and stem diameter. Compared with OF and CK, BOF also significantly increased the fruit numbers and yield： the fruit number increased 7. 6% and 11.6%, and the yield increased 14. 5% and 17.9%, respectively. The yield of BOF reached 46 860 kg/hm2. BOF could improve the soluble solids content （SSC） or decrease the rind thickness of the watermelon to some extent, although there was no significant difference （p 〉 0. 05 ） between treatments.
