1) The efficiency of the NPK nutrient liquid
NPK养分效应
2) nutrient effect
养分效应
1.
Method for estimating asymmetrical nutrient effect model parameters: an optimization regression combining method;
非对称养分效应模型参数估计的一种优化回归组合法
2.
The slowdown of tree growth in the mixed stands is likely attributed to a nutrient effect resulted from re-distribution of N and competition of P and K between the two tested species.
混交对林木生长的影响可能由两树种间N的再分配和P、K的竞争的养分效应所致。
3) NPK Distribution
NPK分配
4) nutrient sparing effect
养分节省效应
5) soil-water and-nutrient effects
土壤水分养分效应
1.
The species diversities,community-structure dynamics,and soil-water and-nutrient effects of 30-year-old Populus simonii plantations,which were located on north-facing slope,half-north-facing,half-south-facing and south-facing slopes in hilly area of the Loess Plateau,were systematically studied.
通过样地调查,对黄土高原丘陵沟壑区处于阴坡、半阴坡、半阳坡、阳坡4种生境条件下,经过30年发育的小叶杨人工林物种多样性,群落结构动态和土壤水分养分效应进行了系统研究,结果表明:(1)不同生境小叶杨人工林总体上物种丰富度、多样性指数和均匀度指数均呈现出阴坡>半阴坡>半阳坡>阳坡的趋势,且林内物种多样性指数表现为:草本层>灌木层;(2)不同生境条件下的小叶杨人工林年龄结构分析表明,尽管阴坡小叶杨长势相对较好,但更新幼苗数量相当有限,很难实现种群的自我更新,不适合作为人工林培育;(3)土壤含水量和养分因坡向不同而呈现出明显的差异,尽管阴坡和半阴坡的水分、养分条件相对较好,但也出现了枯梢、病虫害等衰老特征,因此阴坡、半阴坡的生境对小叶杨来说也不合适。
6) nutritional effects
营养效应
1.
Studies on the biological and nutritional effects of various host leaves on the bollworm
不同寄主植物叶片对棉铃虫的生物学和营养效应比较
2.
This study was intended to investigate the nutritional effects of different soybean products.
将20头3周龄断奶的DLY仔猪随机分成4组,断奶后第1周分别饲喂以膨化全脂大豆、膨化豆粕、膨化去皮豆粕和大豆浓缩蛋白为主要蛋白源的全价日粮,第2周开始,所有仔猪均饲喂同一日粮10d,以考察不同大豆蛋白饲料的营养效应。
