我们从1977年开始进行利用太阳能辐射处理作物种子试验。试验装置主要用上海无线电十五厂研制的伞式太阳灶改制的伞式处理器,共对玉米、小麦、棉花、大豆四种作物进行了14次试验,结果表明:玉米的最佳处理时间(光强1.4兆勒克斯/分)是7分钟,1979年处理的平均亩产687.5斤,比对照增产22.2%;198D年处理的亩产862.5斤,比对照增产18.97%。小麦的最佳处理时间(光强0.5兆勒克斯/分)是20—25分钟,处理的平均亩产达512.5斤,比对照增产21.2%。棉花的最佳处理时间(光强1.5兆勒克斯/分)是3分钟,最高亩产达230斤,比对照增产21.1%,4年平均比对照增产15.1%。
We started the trial of crop seeds using solar radiation from 1977. The experimental device mainly used the umbrella processor modified by the umbrella solar stove developed by Shanghai Radio Fifteen Factory to conduct 14 experiments on four kinds of crops of corn, wheat, cotton and soybean. The results showed that the optimum treatment time of corn Light intensity 1.4 MPa / min) is 7 minutes, an average of 687.5 kg per acre in 1979, 22.2% increase over the control; 198D mu of 862.5 kg, 18.97% increase over the control. The best treatment time for wheat (light intensity 0.5 MBh / min) is 20-25 minutes, the average yield per mu reached 512.5 kg, 21.2% more yield than the control. The best treatment time of cotton (light intensity of 1.5 Mhz / min) is 3 minutes, the maximum yield of 230 kg, 21.1% increase over the control, 4-year average yield 15.1% increase over the control.
