This means when a field where rice is growing floods, accelerated growth in the internodal of the stem allows the plant to keep some of its foliage on top of the water. The O. s. indica cultivar is the main type of deepwater rice, although varieties of O. s. japonica have been found in Burma and Assam Plains. [3] [4]
The rice provides the fish with shelter and shade and a reduced water temperature, along with herbivorous insects and other small animals that feed on the rice. [7] Rice benefits from nitrogenous waste from the fish, while the fish reduce insect pests such as brown planthoppers, diseases such as sheath blight of rice, and weeds. [7]
An oil burner is a part attached to an oil furnace, water heater, or boiler. [1] It provides the ignition of heating oil/biodiesel fuel used to heat either air or water via a heat exchanger . The fuel is atomized into a fine spray usually by forcing it under pressure through a nozzle which gives the resulting flame a specific flow rate, angle ...
Rice husk ash has long been used in ceramic glazes in rice growing regions in the Far East, e.g. China and Japan. [2] Being about 95% silica, it is an easy way of introducing the necessary silica into the glaze, and the small particle size helps with an early melt of the glaze.
One form of fuel staged combustion is the procedure known as burner out of service (BOOS). [4] The technique involves shutting off the fuel flow from one burner or more to create fuel-rich and fuel-lean zones, achieving some NO x emission control (10%). The technique is not widely used in pulverized coal-fired plants (2 units, 350 MW e).
An industrial furnace, also known as a direct heater or a direct fired heater, is a device used to provide heat for an industrial process, typically higher than 400 degrees Celsius. [1] They are used to provide heat for a process or can serve as reactor which provides heats of reaction. Furnace designs vary as to its function, heating duty ...
Were rice a perennial rather than an annual species, its continuously living roots and thick cover of vegetation would prevent such erosion, just as a planting of grass can prevent a roadside slope from washing away. Perennial rice could produce critically needed food year after year on the same plot of land without degrading the soil. [23]
SRI focuses on changing the management of plants, soil, water, and nutrients to create a more productive and sustainable system of rice cultivation. [2] A comparison of SRI grown rice to conventional methods. The methodology has been adopted by millions of smallholder farmers around the world, particularly in Asia and Africa.
