一、栽培情况早籼广陆矮4号是广东省农科院用广场矮3784与陆财号进行杂交育成的。1969年引入我县试种、示范,1972年全县种植面积约一万五千亩。经过4年种植,表现稳产高产,在足肥密植的条件下,增产幅度更大,受到广大贫下中农的好评。1972年在早稻生产中,这个品种不少大队已作当家品种种植,大部份社队扩大示范,加速繁殖,定为1973年的当家品种。实践证明:广陆矮4号是一个稳产高产良种,一般比矮脚南特增产一成左右,随着种植面积的扩大,使早稻单位面积产量提高
First, the cultivation of early indica Canton Lu short 4 is the Guangdong Provincial Academy of Agricultural Sciences with the short 3784 Square and Lu Cai hybrid breeding. Introduced to our county in 1969 trial planting, demonstration, in 1972 the county planted area of about 15000 acres. After four years of planting, the performance of stable yield and high yield, under the condition of adequate fertilizer close planting, the yield increase is even greater, which is well received by the majority of poor and middle peasants. In early rice production in 1972, a large number of brigade of this breed has been planted as a cultivator. Most of the communes and brigades have expanded their demonstration and accelerated their breeding. Practice has proved that: Guanglu Dwarf No. 4 is a stable and high-yielding variety, generally a dwarf Nantes increase about 10%, with the expansion of planting area, so that the yield per unit area of early rice increased
