The source–sink ratio during grain filling is a critical factor that affects crop yield in wheat, and the main objective of this study was to determine relations at both canopy scale individual culm level under two nitrogen (N) levels post-jointing stage. Nine widely-used cultivars were chosen for analyzing southwestern China; three typical different plant types subjected artificial manipulation grain-filling supplement growth measurements. A field experiment conducted over consecutive...
Abstract Water is the most limiting factor for crop production in dryland farming. A better understanding of long‐term impact tillage and residue management systems on soil structure water infiltration necessary further development conservation practice to improve use efficiency. The objectives this study were assess influence no‐till with retention (NT) conventional (plough) removal (CT) properties transmission characteristics a winter wheat (Triticum aestivum) monoculture system Shanxi,...
Rainfall simulator trials were conducted on sugar cane paddocks across dry-tropical and subtropical Queensland, Australia, to examine the potential for spot spraying reduce herbicide losses in runoff. Recommended rates of herbicides glyphosate, 2,4-D, fluoroxypyr, atrazine, diuron sprayed onto 0, 20, 40, 50, 70, or 100% area runoff plots. Simulated rainfall was applied 2 days after induce at one plant three ratoon crop sites. Over 50% all transported dissolved phase runoff, regardless...
Seedling establishment is critical for grain yield and net benefits of wheat in wet clay soil after puddled rice harvest the Yangtze River basin (YRB) China. A wet-resistant rotary strip-till seeder (WR seeder) was developed to drill seeds zero tillage (ZT) conditions with complete residue mulching. The blades adopted were medium radius C type creating a 50–60 mm wide 30–50 deep furrow seed placement. pressing roller, usually used traditional seeders, has been replaced by two ground wheels...
Abstract. Crop residue retention has been recognized worldwide to improve soil structure and fertility, reduce pollution erosion, enhance water retention/conservation. However, some factors limit the widespread adoption of on-farm machinery that can appropriately manage in-field residue. Two key are quality chopping spreading uniformity. This article initially summarized research on blade design, arrangement power consumption. The classified management into three types: single function,...
This paper reports the outcome of 5 years field plot runoff monitoring, 2 water erosion measurement, and a rainfall simulation experiment on moderately sloping farmland loess plateau north-west China. The objective was to test different conservation tillage systems compared with control treatment, conventional mouldboard plough practice (CK). Tillage, residue cover, compaction effects were assessed in terms soil erosion. Results from plots showed that tillage, more less compaction,...
Permanent raised beds have been proposed as a more productive and water-efficient alternative to the conventional system of flat, flood-irrigated bays for planting narrow-spaced crops in arid north-west China. Data from field experiment (2005–2007) conducted Hexi Corridor at Zhangye, Gansu Province, China, were used compared effects traditional tillage (TT), zero (ZT), permanent (PRB) on crop growth, yield, water use spring wheat monoculture. The results show that PRB significantly (P <...
Abstract Calligonum mongolicum is a successful pioneer shrub to combat desertification, which widely used for vegetation restoration in the desert regions of northwest China. In order reveal limitations natural regeneration C. by asexual and sexual reproduction, following process sand dune stabilization, we assessed clonal shoots, seedling emergence, soil seed bank density, physical characteristics mobile stabilized dunes. Controlled field pot experiments were also conducted assess...
Conservation Agriculture (CA) has been shown to improve cropping system performance around the world. However, there is limited research on this practice in annual double areas of North China Plain and consequently uptake technology by farming community. Data from a field experiment (2005 2011) conducted Daxing, Beijing, China, were used compare effects tillage practices, namely permanent raised beds (PRB), no-tillage (NT), traditional (TT) growth, yield, water use winter wheat (<i>Triticum...
The commonly used subsoiling cum rotary tiller machine (SRT) in Northern China is a combination of subsoiler and horizontal tiller, however backfilling the slot, excessive vibration plant residue wrapping on components has been rarely considered. Therefore, assembly were redesigned to address these issues an SRT fitted with IT225 short curve blades behind V-shape slots IIT245 long between tines. Long rotor double helix, optimal spiral angles 65º 90º, phase angle 147º 180º, respectively....
Abstract In arid north‐western China, soil degradation, limited water and subsequent yield decline, largely as a result of excessive tillage residue removal practices, are the main factors limiting further development local agriculture. The effects permanent raised beds (PRB), no‐till (NT) traditional (TT) on structure were investigated in wheat ( Triticum aestivum L.) – maize Zea mays cropping system from 2004 to 2009 Hexi Corridor Gansu Province, China. PRB NT had more macro‐aggregates...
The no-till seeders of various soil opener configurations have been shown to produce physical responses in relation and climate conditions, thus affecting crop performance permanent raised beds (PRB) systems. This is particularly important arid Northwest China where large volumes residue are retained on the surface after harvest. In Zhangye, Gansu Province, China, a field trial assessed effects three typical (powered-chopper, powered-cutter powered-disc) PRB one traditional seeder...
