杂交水稻在汉中地区增产效果显著,但对晒田问题有不同看法。为寻求晒田的科学依据,我们近年进行了试验。试验采用小区对比法,每小区0.2亩,重复3次,布设在本站试验场内。土质中壤。其它栽培措施相同。现将试验结果介绍如下: (一)杂交水稻晒田增产效果试验资料表明:杂交水稻晒田较不晒田的增产11.6％(表1)。据分析晒田可降低田间 Hybrid rice in Hanzhong yield increase effect is significant, but there are different views on the sunning field. In order to seek the scientific basis of tanning, we conducted experiments in recent years. Test using cell contrast method, 0.2 acres per plot, repeated 3 times, arranged in the site test site. Soil in the soil. Other cultivation measures the same. Now the test results are described below: (a) hybrid rice sunning yield test results show that: Shandian hybrid rice Shandian less production increased by 11.6% (Table 1). According to analysis Sha Tin can reduce the field
