摘要:

为评价不同比例肥料对甜瓜果实不同糖分含量及相关酶活性的影响,以甜瓜品种‘脆禧’为材料,在叶面喷施肥料条件下进行设施栽培试验。采用4种不同肥料(N-P2O5-K2O比例含量不同,T1为15-15-15,T2为20-20-20,T3为15-10-17,T4为15-6-35),以普通尿素为对照(T0),探讨不同肥料处理对甜瓜植株生长、SPAD、产量、品质及蔗糖代谢的影响,以筛选出最佳的肥料。与普通尿素(T0)相比,4种肥料处理下,植株生长量差异不明显,SPAD有所增加,其中T3和T4处理差异明显,在这2种肥料条件下,可溶性固形物、可溶性糖、氨基酸、葡萄糖、果糖和蔗糖及糖代谢相关的蔗糖磷酸合成酶(SPS)和蔗糖合成酶(SS)活性明显升高,硝酸盐含量显著降低。综合各指标比较,T3和T4处理下的甜瓜果实产量与对照T0相当,且综合品质有所提高。

Abstract:

To investigate the effect of different fertilizers on plant growth, SPAD, yield, quality and sucrose metabolism of melon under protected cultivation condition, cultivar ‘Cuixi’ was sprayed with four different fertilizers (mainly different in N-P2O5-K2O ratio, T1: 15-15-15, T2: 20-20-20, T3: 15-10-17, T4: 15-6-35), common urea was used as control (T0). The results showed that compared with common urea (T0), the difference of plant growth was not significant under the four fertilizers’ treatment, and the SPAD increased. There were significant differences under T3 and T4, in which, soluble solids, soluble sugar, amino acid, glucose, fructose, sucrose and glucose contents, the activities of sucrose phosphate synthase (SPS) and sucrose synthetase (SS) increased significantly, and nitrate content decreased significantly. The results showed that the fruit yield of melon under T3 and T4 treatment was nearly to that of control (T0), and the comprehensive quality was improved.

Key words: melon, fertilizer, growth, fruit quality, sucrose metabolism
