我国北方常把有希望的品种(品系)拿到海南岛加代繁殖,这是行之有效的.但是,从北方到南方要长途跋涉,生活不便,花费较大,在育种前期和为了暂时获得的单果单株或少量种苗专程南繁一趟,一般不易办到.南疆冬春气候较暖,晴天较多,日照时间长(年平均2,800小时,最长达3,200小时),辐射强度大(年总辐射量每平方米140—160万卡),我们利用此条件建造日光暖室(冬季不另加温)生产蔬菜已获显著成效.为了探索日光温室对粮食作物加代繁殖的可能性,我们于1981年11月在日光温室内
However, it is inconvenient and costly to travel long distances from the north to the south in the early stages of breeding and for temporary purposes Single or a small amount of single fruit seedlings a trip south trip, generally difficult to do.Nanjiang winter and spring climate is warmer, sunny days, long sunshine (an average of 2,800 hours, up to 3,200 hours), radiation intensity ( The annual total radiation of 140-160 million cards per square meter), we use this condition to build solar heating room (no additional heating in winter) to produce vegetables have achieved remarkable results.In order to explore the solar greenhouse for food crops and the possibility of multiplication, we In November 1981 in the greenhouse
