为研究两种新型的有机叶面肥在茶树上的肥效和效益比较,试验通过在茶园日常管理中设置喷施植物提取物SA-1、氨基酸有机肥YM-1和对照CK处理,调查研究施肥后一个周期内茶树生长、产量及品质变化情况.结果表明:叶面喷施有机肥可以提高茶树发芽密度、百芽重进而提高产量,并明显改善制茶品质,最终体现在提高茶园产值和效益上,是一种高效栽培模式,对于实现茶园化肥投入减量和茶树轻简栽培具有良好的应用前景.
以黑叶、禾荔、妃子笑3个广西大宗品种荔枝果肉为原料,经乳酸菌复合菌种发酵得到荔枝发酵饮料.在此基础上,以发酵饮料为研究对象,采用气质联用(GC-MS)法对比分析了3个品种荔枝发酵饮料的挥发性香气成分及含量.研究结果表明,黑叶、禾荔、妃子笑3个品种荔枝发酵饮料中共检出香气成分72、48、52种,主要以烯类和醇类为主.黑叶、禾荔、妃子笑品种荔枝发酵饮料中含量最高的挥发性香气物质分别为香茅醇(16.63%)、乙醇(17.62%)、顺式玫瑰醚(11.33%).三种荔枝发酵饮料的挥发性香气成分差异较大,其中黑叶品种荔枝发酵饮料中致香成分最丰富,明显多于另外两种.
There was significant effect oi testing soil balance iertilization on yield,quality and beneiit of corn. It displayed mainly to improve nutritional growth of corn,to increase effective panicle, panicle length, kernel rows per ear, kernels per row and 1 000-grain weight,to improve the content of grain protein ,fat and starch in corn,to decrease soluble sugar content and to improve quality of corn. Under experiment condition ,the unit yield of testing soil balance fertilization (9 071.9 kilograms per hectare)increased by 1 686.7 kilograms and 22.8 percent compared with the conventional fertilizer application (7 385.2 kilograms per hectare ).The net-increased benefit of testing soil balance fertilization (27 840.66 yuan per hectare ) increased by 5 951.98 yuan per hectare and 27.2 percent compared with the conventional fertilizer application (21 888.68 yuan per hectare ). It also get analogous effect in the field demonstration. Moreover ,this method had good reproducibility and remarkable increasing yield and revenue.
