摘要
以鲁厚甜1号为试验材料,研究了钙肥对日光温室网纹甜瓜的生长发育、果实品质和土壤理化性状的影响。结果表明,与CK(只施用底肥)相比,T1(底肥+固体钙肥)、T2(底肥+液体钙肥),T3(底肥+固体钙肥+液体钙肥)处理可使网纹甜瓜授粉日期和采收日期分别提前1~2 d,3~5 d;3种钙肥处理均可显著增加株高、单瓜质量、果实硬度、Ca含量、商品瓜率、总产量和网纹数,分别比对照提高了4.02%~10.27%、4.82%~12.65%、5.55%~23.58%、38.13%~73.46%、3.81%~11.53%、5.90%~15.13%、5.95%~15.48%,但对茎粗、节长、果实的维生素C含量影响不大,均与对照差异不显著;3种处理下试验后土壤pH值比试验前提高1%~8%,交换性钙含量增加19%~44%。综上所述,底肥、固体钙肥和液体钙肥(T3处理)配合施用网纹甜瓜产量最高。
Taking Luhoutian No.1 as the experimental material,the effect of calcium fertilizer on the growth and development,fruit quality and soil physiochemical properties in the solar greenhouse were studied.The results showed that compared with the CK(Organic fertilizer),T1(Organic fertilizer and solid calcium fertilizer),T2(Organic fertilizer and liquid calcium fertilizer)and T3(Organic fertilizer,solid calcium fertilizer and liquid calcium fertilizer)treatments could advance the pollination and harvesting date by 1-2 d and 3-5 d,respectively;The three treatments could significantly increase plant height,single melon weight,fruit hardness,Ca content,commercial melon percentage,total yield and reticulate number,it increased by 4.02%-10.27%,4.82%-12.65%,5.55%-23.58%,38.13%-73.46%,3.81%-11.53%,5.90%-15.13%,5.95%-15.48%,respectively,but had no significant effects on stem diameter,node length and vitamin C content,with no significant differences.The pH value and exchangeable calcium content increased by 1%-8%and 19%-44%after treatment,respectively.The results showed that the combined application of base fertilizer,solid calcium fertilizer and liquid calcium fertilizer(T3 treatment)could increase the yield of muskmelon to the maximum extent.
