去年,我们在马路大队合作五队又进行了杂交水稻高产栽培试验,面积5.367亩,获得了增产,双造平均亩产2360斤,其中最高田块亩产2589斤,最低田块也有2235斤。就组合而言,以汕优二号产量最高,面积1.59亩,早造亩产1325斤,晚造亩产1264斤。早造种了南优二号和汕优二号两个组合,在高产栽培的同时,还设置了不同施肥量和单株双株插植试验。试验田是沙质壤土,地力比较高,都是历年的高产试验田。晚造种了汕优二号、三号和金优二号三个组合,都属感温类型,生育期比早造明显缩短。由于施肥和管理与早造基本相同,造成
Last year, we conducted a trial of high-yielding hybrid rice cultivation with an area of 5.367 mu with an area of 5.367 mu and an area of 2,360 kg of mu per mu. The highest paddy field produced 2589 kg of mu per mu and the lowest padded area also received 2,235 kg of barley. In terms of portfolio, the highest output of Shanyou 2, an area of 1.59 acres, as early as 1325 pounds per mu, mu produce late 1264 pounds. As early as the two varieties of South You 2 and Shanyou 2 were planted. In addition to the high-yielding cultivation, different fertilization rates and single double-plant planting were also set up. The experimental field is sandy loam with high ground force, all of which are high-yield experimental fields over the years. Night sowing Shanyou two, three and Jinyou two three combinations are temperature type, growth period was significantly shorter than the previous. As a result of fertilization and management basically the same as the early made
