本总结包括示范园技术总结和七个单项研究简明结论。58亩示范园三年平均亩产1302公斤,较试验前三年平均亩产634公斤增产60％;平均含糖量16.4度,较前三年13.7度提高2.7度;平均每亩纯盈利625元,较前三年310元增加102％。试验表明故道地区葡萄含糖量主要受降雨量及高温影响,栽培措施的增糖效果甚微,各种栽培措施平均可增糖0.35度,况且不是多种措施的累加效果。控制病害,按品种糖度增长规律适时采收,虽不能从本质上增加含糖量,确是目前提高含糖量的有效方法。“高、宽、垂”树形较扇形有明显增产、省工、病害轻的优点。白羽品种亩产1300公斤左右对,含糖量最高,其经济效益大于或等于产量的提高。
This summary includes the demonstration garden technology summary and seven individual concise conclusions. The average yield per mu of the 58-mu demonstration garden was 1302 kg in three years, an increase of 60% over the previous three years of trial production of 634 kg. The average sugar content was 16.4 degrees, an increase of 2.7 degrees over the previous three years of 13.7 degrees. The average net profit per mu was 625 yuan , An increase of 102% over 310 in the previous three years. The experiment shows that the sugar content of grape in the old course is mainly affected by the rainfall and the high temperature. The cultivation measures have little effect of adding sugar. The average increase of various sugarcane cultivation measures is 0.35 degree, which is not the cumulative effect of various measures. Control diseases, according to the law of the growth of sugar content timely harvest, although not essentially increase the sugar content, is indeed an effective way to improve sugar content. “High, wide and vertical,” the tree has a significant increase in fan-shaped, labor-saving, light advantages of disease. White feather species of about 1300 kg per mu, the highest sugar content, its economic efficiency is greater than or equal to the increase in production.
