新型可降解地膜对网纹甜瓜产量和品质的影响

Influence of New Type Covering Degradable Mulch on Yield and Quality of Netted Muskmelon

为以3种规格无纺布地膜(30、40、50 g/m^2)为试验材料,比较了3种规格地膜的降解时间,研究了不同厚度地膜覆盖对网纹甜瓜长势、产量、品质以及土壤含水量的影响。试验结果表明,3种规格无纺布地膜对植株田间长势影响不明显,30 g/m^2地膜处理下网纹甜瓜单瓜质量和产量最高,网眼数最多,果肉也最厚,果实糖含量与40 g/m^2地膜处理的相比略低,但口感依然俱佳,综合考虑,种植网纹甜瓜建议选用30 g/m^2地膜,价格较便宜,易被农户接受。

In order to screen out suitable degradable covering mulch for facilities muskmelon cultivation in Beijing area,3 kinds of non-woven mulch(30,40,50 g/m2)were used as test materials,and their degradation time was compared,additionally the effects of different mulch on netted muskmelon growth,yield,quality and soil water content were studied.The results showed that these 3 kinds of non-woven mulch had no obvious effect on plant growth vigour in the field.The single fruit weight and yield of netted muskmelon was the highest while covered by 30 g/m2 mulch,and it had the maximum number of mesh and thickest fruit pulp.Its fruit sugar content was slightly lower than that of the 40 g/m2 mulch treatment,but it still tasted good.Comprehensive consideration,30 g/m2 mulch treatment was the best choice which had the advantage of cheap and easily accepted by farmers.
