汉中海拔550—900m 的巴山浅山丘陵区约有稻田38万亩,由于栽培技术不够合理,水稻单产水平低,稳产性能差。根据我们试验示范结果,采取“五改两防一坚持”配套栽培技术,增产效果比较理想。我所南郑县黄官农业综合实验基地全面推广“五改两防一坚持”配套栽培技术,获得水稻大幅度增产。1986年全区35682亩水稻平均亩产440kg,较前 Hanzhong elevation of 550-900m Bashan shallow hills about 380,000 mu of paddy fields, due to inadequate cultivation techniques, low level of rice yields, stable performance poor. According to the results of our experiment and demonstration, adopting the “five reforms and two defenses and one persistence” supporting cultivation techniques, the yield increase effect is ideal. I Nanzheng County Huangguan comprehensive agricultural experimental base to comprehensively promote the “five changes two against one adhere to” supporting cultivation techniques, access to substantial increase in rice. In 1986, the average output of 35,682 mu of paddy in the region was 440 kg, more than before
