Intercropping and N fertilization play an important role in increasing crop yield.In order to further understand the advantage mechanism of intercropping effect application on intercropped crop, a field experiment was conducted investigate effects different cropping patterns (i.e.M, maize monoculture; I1, maize-cotton intercrop; I2, maize-soybean intercrop) levels (N1, 100 kg ha -1 ; N2, 200 N3, 300 N4, 400 ) (Zea mays L.) Results showed that could enhance green leaf area per plant...
Abstract A large number of economic forests, especially apple orchards (AOs) in the Loess Plateau region China, have been planted to develop local economy and increase income farmers. The two main constraints preventing AOs on from developing sustainably producing a high steady yield are soil moisture content (SMC) organic carbon (SOC). Nevertheless, little is currently known about contributions roots these changes profile temporal modes SMC-SOC coupled effects. In our research, we analyzed...
Apple is an economically important fruit crop in northern Shaanxi Province China. In recent years, a new type of apple black spot disease, "bagged disease," has occurred the main production area Yan'an City, Province, during ripening season. It seriously affects appearance quality and commercial value apples. this study, 120 isolates recovered from symptomatic apples were identified based on morphological characteristics, pathogenicity, multilocus sequence analyses internal transcribed...
The one-time application of slow-release nitrogen fertilizer can not only reduce the labor input, but also mechanical input cost, and has characteristics slow release volatilization loss. This research is grounded in a localization trial initiated 2018, which underwent comprehensive analysis utilizing high-throughput sequencing technology to elucidate mutual feeding mechanism rate on microbial community structure, network complexity, maize yield different root niches (bulk soil, rhizosphere,...
To fully explore the effects of N on enhancing photosynthesis, grain quality, and yield wheat (Ningmai 13), experiments with four nitrogen levels 0 (N0), 120 (N1), 180 (N2), 240 (N3) kg ha−1 ratios basal to topdressing R0 (0:0), R1 (7:3), R2 (6:4), R3 (5:5) were conducted. The was applied soil before sowing at jointing stage. effect ratio improving leaf area photosynthetic efficiency insignificant under same level. fertilization level increasing chlorophyll content more significant than that...
Intercropping is a very effective cultivation method in the agricultural production with long history. The use of intercropping to build niche complementary crop community can not only enhance stability farmland ecosystem and resistance environmental stress but also reduce damage diseases, insect pests, pollution improve efficiency resource finally achieve high stable yield community. By collecting researches at home abroad, this thesis describes impact on nitrogen fixation transfer,...
摘要:...
Optimizing the N application amount and topdressing ratio can increase crop yield decrease loss, but its internal mechanisms have not been well studied, especially from aspects of population dynamics structure, ear fruiting traits. Here, field experiments, with three rates 120 (N1), 180 (N2), 240 (N3) kg ha-1 ratios T1 (7:3), T2 (6:4), T3 (5:5) were conducted. At same level, results showed that accumulation amounts in leaf, grain, plant higher than T1, increasing 60 (N3 compared to N2, N2...
为深入了解间作豆科作物的边行效应, 研究了低施氮肥条件下(50 kg·hm<sup>-2</sup>)玉米对间作大豆和花生边行(叶绿素、叶面积指数、根干重、根瘤、农艺性状及产量)的影响。结果表明: 无论在施氮肥和不施氮肥条件下间作大豆和花生边1行和边2行的叶绿素含量在不同生育时期均高于其单作, 而边3行与单作相比变化不明显。间作同样可以增加大豆和花生不同生育时期边1行和边2行的叶面积指数, 而对边3行无明显影响, 且间作的效果小于该施氮水平。不施氮条件下, 间作大豆边1行和边2行的单株根干重高于单作14.7%和2.8%, 间作花生边1行和边2行高于单作16.5%和3.1%; 施氮条件下, 间作大豆边1行和边2行的单株根干重高于单作11.3%和1.3%, 间作花生边1行和边2行高于单作13.5%和4.6%, 而边3行与单作相比无明显变化, 且该施氮肥的效果大于间作。间作同样可以增加大豆和花生边1行和边2行成熟期的单株根瘤数和根瘤重, 而该施氮水平对根瘤数和根瘤重具有一定的抑制作用。施氮肥和间作可以改善大豆和花生的农艺性状,...
To clarify the changes of root traits, soil biological characteristics and yield after applying fertilizers for 39 years, a long-term located fertilization experiment (1981-) was conducted. Compared to NPK (inorganic fertilizer) M (organic fertilizer), 0.8NPKM (80% plus 80% M) 0.5NPKM (50% 50% obviously improved traits. The number bacteria, fungi, actinomycetes in were significantly higher than that NPK, CT (no fertilizer). increased microbial quantity. Soil biomass carbon nitrogen, organic...
The quality of weak-gluten wheat is easily affected by management methods field cultivation. U nmanned aerial vehicle (UAV) remote sensing technology can provide technical support for the optimization cultivation plan dynamically monitoring growth canopy. In this study, digital and multispectral cameras mounted on UAV were used to capture canopy images during key stages. visible vegetation indexes 10 kind varieties calculated. correlation between 13 ground-measured chlorophyll content SPAD...
Abstract The clarification of the dry matter accumulation, distribution law and yield differences silage corn under different nitrogen application rates will provide theoretical basis for determining optimal drip irrigation in central Inner Mongolia. In this study, Zhongxing 1 was selected as experimental variety. This paper systematically analyzes fresh weight accumulation growth rate, index whole period condition six amount two consecutive years 2018 2019. results indicated that fertilizer...
