以“黑美人”西瓜为试材,通过连续2年试验,即设单施有机肥(A)、有机肥化肥配合施用(B)2个处理,分别以不施肥(CK-1)和单施化肥(CK-2)作为空白和常规施肥对照,所有施肥处理的氮、磷、钾养分总量一致,均为750kg·hm-2,分析不同处理对西瓜主蔓长、茎径、有效分蔓数、产量及品质指标的影响,并综合评价木薯加工废弃物转化有机肥料的田间施用效果,为木薯加工废弃物资源的当地肥料化应用提供依据。结果表明:与空白对照(CK-1)处理相比,连续2年所有施肥处理均能促进西瓜生长、提高西瓜果实产量和品质;与常规施肥(CK-2)处理相比,单施有机肥的A处理在试验实施第1年西瓜生长受到明显抑制,产量显著降低,但品质明显提高,持续实施的第2年,生长受到的抑制程度减弱,产量和CK-2无明显差异,品质仍显著高于CK-2处理;而有机肥和化肥配合施用的B处理连续2年西瓜营养生长、产量及品质均优于常规施肥处理。因此,木薯加工废弃物转化有机肥料后和化肥配合施用能有效促进西瓜植株营养生长,提高西瓜产量,改善西瓜品质。
Using “Black Beauty” and “Watermelon” as test materials, the experiment was carried out for two consecutive years, ie, applying single organic fertilizer (A) and organic fertilizer combined with applying (B) Fertilizer (CK-2) as a blank and conventional fertilization control, the total amount of nitrogen, phosphorus and potassium fertilizers were the same, both 750kg · hm-2, analysis of different treatments on the main watermelon length, stem diameter, effective The results showed that the effect of transplanting organic manure into cassava processing was better than that of manure processing, which provided the basis for local manure application of cassava processing waste. The results showed that compared with the control (CK-1), all the fertilization treatments for 2 consecutive years could promote the growth of watermelon and increase the yield and quality of watermelon fruits. Compared with the CK-2 treatment, Of A treatment significantly inhibited the growth of watermelon in the first year of experiment, the yield was significantly reduced, but the quality was obviously improved. In the second year of continuous implementation, the inhibition of growth was weakened, the yield and CK-2 had no obvious difference, the quality was still significant Higher than that of CK-2 treatment; and the application of organic manure and chemical fertilizer B treatment for two consecutive years of watermelon vegetative growth, yield and quality are better than conventional fertilization. Therefore, cassava processing waste into organic fertilizers and chemical fertilizers with the application can effectively promote the nutritional growth of watermelon plants to improve watermelon yield and improve watermelon quality.
