Wood ash production from power plants and the use of recycled ash for earthworks and forest peatland fertilization have increased markedly in Finland in recent decades. In this study, effects of wood...
The high erosion rates found in the agriculture land make valuable the use of mulches to control the soil and water losses. Coffee husk (Coffea canephora var. robusta) can be one of those mulches. Thi...
通过不同高度土体在不同覆膜开孔率条件下的室内蒸发试验,研究了土体高度变化时水盐分布的差异与相互联系。试验结果表明,不同高度土体的单位深度累积蒸发量与时间变化符合Gardner理论关系,单位深度累积蒸发量与时间和土体总高度存在二元线性函数关系;单位深度累积蒸发量和单位膜孔面积单位深度累积蒸发量均与土体高度和覆膜开孔率存在较好的函数关系;土体高度越小,单位深度含盐量和盐分浓度变化幅度越大,土体高度是影...
设计了一种基于蒸发量的简易灌溉预警装置,并建立了基于水量平衡原理的灌溉预警模型。通过田间试验,确定了适宜供水条件下新疆膜下滴灌棉花各生育阶段的蒸发皿—作物系数,并建立了适宜的灌溉预警指标,提出了降雨条件下的指标修正方法。田间应用表明,在北疆棉花膜下滴灌条件下,苗期、蕾期、花铃期和吐絮期分别以累计蒸发量达到140、75、50和120mm来控制灌水时间,以0.15、0.4、0.7和0.25倍的累计蒸...
A two year field study was conducted during 2001-2002 and 2002-2003 on sandy loam soil to investigate the effect of drip irrigation and black polyethylene mulch compared with surface irrigation, on gr...
Growing in Plastictunnel-mulch and Breeding of Sweet Potato in Kochi.
Establishment of Rice Seedlings by Direct Sowing of Multiple Seed Pellets on Paddy Soil Covered with Legume Living Mulch.
The use of recycled paper mulch for rice cultivation eliminates the need to use herbicides. The technology of transplanting with recycled paper mulch has been established and used by farmers in Japan....
The direct sowing culture of rice with recycled-paper mulch is practiced by spreading recycled paper (t owhich rice seeds are attached) on the surface of puddled soil. This cultural practice would eli...
To apply mulch for leaf and root crop cultivation with high planting density, we tried to use a paper mulch combined with seed tape, which allows simultaneous mulch installation and seed sowing. When ...
To estimate the nitrogen competition between crops and living mulch plants, we compared the nitrogen flow in the sweet corn (Zea mays L.) - white clover (Trifolium repens L.) living mulch system (LM)...
For operation without herbicide and intertillage of soybean in Tohoku region of Japan, we investigated the effect of a winter-type barley living mulch system on weed suppression, growth and yield of ...
White clover (Wc) has been reported as one of the effective living mulch plants.We investigated sweet corn (Sc) yield under Wc living mulch without trimming during the growth period of Sc in southern ...
This study was conducted to develop a new growing system that combines high density planting and fertigation of grapevines in order to achieve early establishment, and increased production of high qua...
The effects of the beginning time of flooding on legume decomposition, N release, growth and yield of rice cultivated with white clover living mulch were investigated by field and pot experiments. Th...
