我区水稻集中在川道、浅山丘陵区。据安康、汉阴、石泉三县43个公社统计,1978年插秧面积16.3万多亩,占全区稻田面积41.2％。这里是稻麦两熟主产区,麦茬稻面积过半,而单产偏低。1978年发展杂交稻以来,川道麦茬种植杂交稻显著增产。安康县连续四年丰收,该县张汰公社张汰大队1978年试种,1979年扩大到四个大队十二个生产队,面积378.7亩,平均亩产872斤,比常规稻高出164斤。1980年我们在安康县建设公社建设大队,五里公社五四大队,民强公社朝阳大队示范麦茬杂交稻228亩,平均亩产832斤,比常规稻多收198斤,增产31.2％。1981年安康县恒口、五里两区面积发展到10500亩,占杂交稻面积75％。据分析麦茬杂交稻增产的原因是:
Rice in our area concentrated in Sichuan Road, shallow hills. According to well-being, Hanyin, Shishuquan 43 communes statistics, 1978 planting area of 163,000 mu, accounting for 41.2% of the area of paddy fields. Here is the main producing areas of rice and wheat, wheat stubble area of more than half, while the yield is low. Since the development of hybrid rice in 1978, the yield of hybrid rice has been significantly increased by the wheat stubble of Chuandao. Ankang County bumper harvest for four consecutive years, Zhang County, the county Zhangzhi brigade in 1978 trial planting, 1979 expanded to four brigade production team of 12, an area of 378.7 acres, an average of 872 kg per mu, higher than conventional rice 164 pounds . In 1980, we built the commune construction brigade in Ankang County and the Wusi commune May Fourth Brigade and the Democrats’ commune Chaoyang Brigade demonstrated 228 hectares of malt hybrid rice with an average yield of 832 kilograms, 198 kilograms more than the conventional rice and an increase of 31.2%. In 1981, Ankang County, Hengkou, Wuli two area developed to 10,500 acres, accounting for 75% of hybrid rice area. According to the analysis of wheat stubble hybrid rice yield reasons are:
