为了获得最高的稻谷产量,确定最适的移栽日期是必需的。我们使用了稻谷产量模式与水分和能量利用效率来确定恰当的种植日期。试验于1981年雨季,在Raipur(北纬21°14′东经81°39′)pH6.5的粘壤土上进行。品种Asha(一个矮秆籼稻)于6月1日至8月30日,分10期种植,每期间隔10天,重复3次,行穴距10×20厘米,每公顷施N100公斤、P26公斤、K33公斤。通过抄写人的平均和农业气象台所记录的气象参数估算了净辐射量和可能的水分蒸散量。
In order to obtain the highest paddy yield, it is necessary to determine the most suitable date of transplanting. We used paddy production patterns and moisture and energy efficiency to determine the right planting date. The test was carried out on the rainy season of 1981 on the clay soil of Raipur (latitude 21o 14 ’81o 39’ E) pH6.5. The variety Asha (a dwarf indica rice) was planted in 10 phases from June 1 to August 30, with intervals of 10 days and repeated 3 times with a hole distance of 10 × 20 cm, applying N100 kg per hectare and P26 kg , K33 kg. Net radiation and possible evapotranspiration were estimated by transcribing the anthropogenic average and the meteorological parameters recorded by the agrometeorological observatory.
