今年,赤水市种子公司的25亩杂交水稻制种试验田开镰收割,经晒干扬尽,过磅测算,亩产稻种125千克。 早在70年代末80年代初期,赤水曾大面积进行过杂交水稻育种,因当时技术水平低,亩产稻种只有50千克左右。后来又曾断断续续作过育种试验,都因种种原因未能扩大面积。 这次进行杂交水稻育种试验,是按照贵州省和遵义市实施种子工程,逐步实现种子自给的计划进行的。试验田选在距赤水市区8公里
This year, Chishui City seed company 25 acres of hybrid rice seedling open field sickle trial harvest, the sun dried to make, weighing measurement, mu yield of 125 kg of rice. As early as the late 1970s and early 1980s, Chishui had conducted hybrid rice breeding on a large area due to the low level of technology at that time and only about 50 kg of rice per mu. Later, they made intermittent breeding experiments, all due to various reasons failed to expand the area. This hybrid rice breeding experiment is carried out according to the plan of implementing seed project in Guizhou Province and Zunyi City and gradually realizing self-sufficiency of seeds. Experimental field election from Chishui 8 km
