Effects of straw mulching on maize photosynthetic characteristics and rhizosphere soil micro-ecological environment
Straw mulching is an effective measure to improve soil properties, crop growth, and yield. To further understand the advantage mechanisms of straw mulching, a field experiment with seven straw mulching levels (0 to 18 000 kg ha-1) was conducted to study the effects of straw mulching on maize (Zea mays L.) photosynthesis and rhizosphere soil microecological environment. Results showed that maize...
متن کاملEffects of Silicon on Photosynthetic Characteristics of Maize (Zea mays L.) on Alluvial Soil
The objectives of the study were to determine the effects of silicon on photosynthetic characteristics of maize on alluvial soil, including total chlorophyll contents, photosynthetic rate (P n), stomatal conductance (g s), transpiration rate (E), and intercellular CO2 concentration (C i ) using the method of field experiment, in which there were five levels (0, 45, 90, 150, and 225 kg · ha(-1))...
متن کاملResponse of Soil CO2 Emission and Summer Maize Yield to Plant Density and Straw Mulching in the North China Plain
Demand for food security and the current global warming situation make high and strict demands on the North China Plain for both food production and the inhibition of agricultural carbon emissions. To explore the most effective way to decrease soil CO2 emissions and maintain high grain yield, studies were conducted during the 2012 and 2013 summer maize growing seasons to assess the effects of w...
متن کاملmulching and cover crops effects on the soil and rhizosphere-associated bacterial communities in field experiment
agricultural sustainability is closely related with the efficient use of natural resources, which are primarily transformed by the action of microorganisms. soil microorganisms are usually used as early indicators of soil quality since they rapidly respond to changes in soil management. a field experiment was carried out aiming to evaluate the effect of siratro (macroptylium atropurpureum), bah...
متن کاملEvaluation of compost and straw mulching on soil-loss characteristics in erosion plots of potatoes in Prince Edward Island, Canada
The intensive use of Prince Edward Island (PEI) farmland for potato (Solanum tuberosum L.) production draws concern because of soil physical degradation under the intense tillage and other heavy traffic associated with the mechanisation of this crop, and the resulting vulnerability of sloping fields to hydraulic erosion. Growing public consciousness and pressure in favour of sustainable agricul...
