自1973年以来,我们连续进行了五年三熟制早稻的高产试验,产量水平一般在1000斤左右到1100多斤。其中1976年亩产达到1130.3斤,最高的2.04亩,亩产达到1212.3斤。1977年虽然受到高温等不利气候因素的影响,5.98亩试验田,亩产仍达1062斤。出现了三熟制早稻稳定超千斤的可喜局面。通过几年的实践,我们对广陆矮4号作三熟制早稻栽培,当前的主攻方向是什么?有了一点粗浅的认识。现提出来,供参考讨论。
Since 1973, we have continuously conducted high-yield trials of three-year-old early rice for five years, with output levels generally ranging from about 1,000 to 1,100 kilos. Among them, the per-mu yield reached 1130.3 kg in 1976 and the highest was 2.04 mu, with a yield of 1212.3 kg per mu. Despite adverse climate factors such as high temperature in 1977, 5.98 mu of experimental field had a yield of 1062 kg per mu. There has been a three-cooked rice super-stable stable overweight situation. After several years of practice, we Guanglong Dwarf No. 4 for the cultivation of three lines of early rice, the current main direction is what? A little superficial understanding. Now put forward for reference.
