施用不同土壤改良剂对西瓜产量及品质的影响

Effects of different soil amendments on the yield and quality of watermelon

为了探讨不同土壤改良剂对西瓜产量及改善土壤盐渍化效果的影响,选取5种土壤改良剂进行土壤改良效果试验,5种改良剂分别为松壤水剂、禾康、靠山多霸、松壤粉剂和阔立.结果表明,土壤改良剂可显著降低土壤EC,其中施用禾康效果最佳,土壤EC降低了45.54%;土壤改良剂还能够显著降低土壤容重,其中靠山多霸、阔立和禾康对土壤容重改良效果最佳,土壤容重分别降低了7.04%、6.34%和6.34%,改良效果达到极显著水平;同时还能显著提高西瓜产量,施用禾康后每667m2西瓜产量达到2 539.6 kg,较对照高9.31%,显著高于其他处理.综合各项试验结果得出,施用禾康盐碱土壤改良剂处理的产量和脱盐率均为最高,且能显著改善西瓜品质,效果显著,可推广使用.

In order to study the effect of soil amendments on watermelon yield and soil salinization, five kinds of soil amendments were selected randomly to carry out soil improvement experiment. The five kinds of soil amendments were respectively Songrangshuiji, Hekang, Kaoshanduoba, Songrangfenji and Kuoli. The results showed that the soil amendments could significantly improve soil structure and reduce soil EC, among which Hekang showed the best effect, soil EC of which was reduced by 45.54%. Soil amendments could also significantly reduce soil bulk density, among them Kaoshanduoba, Kuoli and Hekang exhibited better effect, soil bulk density of which were reduced by 7.04%, 6.34% and 6.34%, respectively, the improvement effect reached a very significant level. The yield of watermelon was 2 539. kg per 667 m2 after applying Hekang, which was 9.31% higher than that of control. The results showed that the yield and desalination rate of the treatment with Hekang were the highest, which could be popularized.
