Abstract

In order to solve the problem of low absorption and utilization efficiency of base fertilizer in fresh corn, ‘Nongkeyu 336’ was used as the experimental material, and three treatments were set up, including basal application of ternary compound fertilizer (T1, 15-15-15) 500 kg/hm², amino acid compound fertilizer 865.4 kg/hm² (T2), and slow-release mixed fertilizer 865.4 kg/hm²(T3). The effect of base fertilizer selection on the yield and quality of fresh corn was studied. The results showed that compared with the conventional basal application of ternary compound fertilizer (T1), basal application of amino acid-containing compound fertilizer (T2) and slow-release mixed fertilizer (T3) could improve ear traits, reduce bald tip and improve ear commodity. Compared with T1, the yield of fresh corn under T2 and T3 treatments increased by 3.05% and 8.01%, respectively. The harvest indexes of nitrogen, phosphorus and potassium increased by 25%, 36%, 0% and 31.25%, 32%, 20%, respectively. The contents of crude protein, crude fat and crude starch in grains increased by 1.98%, 1.98%, 4.99% and 0.56%, 3.93%, 2.77%, respectively. The contents of water-soluble sugar and sucrose in grains under T3 treatment were 1.18 % and 19.48 % higher than those under T1 treatment, respectively. In summary, in the actual production, the part that focuses on the nutritional quality of grain can give priority to the application of amino acid-containing compound fertilizer as the base fertilizer, and the part that focuses on the comprehensive effects of yield, fertilizer effect and grain taste can give priority to the application of slow-release mixed fertilizer as the base fertilizer.

对日常食用的主要粮食及果蔬的叶酸含量进行测定与评价，为人体科学合理补充叶酸提供理论依据。在山西省各农户及市场搜集11 种主要粮食、17 种常见蔬菜、8 种常见水果。粮食样品研磨全部过100 目筛子备用，市售新鲜果蔬样品将可食用部分随机多点采样，切碎混合。食物叶酸用磷酸二氢钾溶液恒温水浴浸提，加苯胺处理过的活性炭吸附，用体积分数3%氨-70%乙醇洗脱，采用高锰酸钾氧化-间接荧光法测定。结果显示，主要食物叶酸含量存在差异，叶酸含量较高的粮食种类有：大豆、花生、绿豆、小米、燕麦、玉米和苦荞，含量均在1.56 μg/g（以干质量计）以上；含量较高的蔬菜有：菠菜、油菜、香菇、油麦菜、生菜、卷心菜、青椒、芹菜、白菜和南瓜，含量均在1.53 μg/g（以湿质量计）以上；人们日常食用的水果叶酸含量均在1.74 μg/g（以湿质量计）以上；只要合理调整膳食结构，粗细搭配，多摄食蔬菜水果，就有望通过食疗来补充人体所缺乏的叶酸。

通过田间试验研究在施用化肥的基础上增施氨基酸对白菜产量、根系活力及土壤酶活性和土壤微生物生物量的影响。结果表明，增施氨基酸较单施化肥处理增产2.62%~11.50%，根系活力和硝酸还原酶活性提高，硝酸盐含量下降。而土壤蔗糖酶和脲酶活性在不同生育时期均较化肥处理提高，酸性磷酸酶活性在白菜生长后期有一定程度的提高。此外，土壤微生物生物量碳和微生物生物量氮均随着氨基酸用量的增加而提高。说明在施用化肥的基础上施用氨基酸能够对白菜起到增产、提高品质、改善土壤生物活性的效果。
