刺槐是沙区、山丘区造林的重要树种.刺槐育苗一般在春季播种,这需要有可靠的水利条件和技术措施,才能达到较好的经济技术指标.但在缺乏水利条件的沙区、山丘区,遇到严重的春旱时刺槐春播育苗常常是出苗齐,保苗难,往往导致育苗失败.围绕这一技术关键,1965年,我们在新乡地区几个国营林场搞了刺槐秋季随采随播小面积试验,此后,陆续又在部分地区用隔年种子进行秋播试验,均获成功.1982年秋,推广到延津、原阳、济源等县,育苗面积扩大到1600亩,获得大面积成功经验.据对原阳、延津等县六个生产单位的调查,每亩播种量8-10斤,产苗量2-3万株,个别高达8.7万株,经间苗定苗后保存8000-10000株.比春播相同播种量,成苗3000-4000
Robinia pseudoacacia is an important tree species for afforestation in sandy areas and hills, and Robinia pseudoacacia seedlings are generally sown in spring, which requires reliable water conservancy conditions and technical measures to achieve better economic and technical indicators.But in sand areas lacking in water conservancy, Hill area, encountered severe spring drought acacia spring sowing seedlings are often out of Qi, seedling difficult, often lead to nursery failure around this key technology, in 1965, we Xinxiang several state-owned farms engage in acacia autumn with mining Sowing small area test, after which, after another in some areas with the next year seed autumn sowing test, were successful .1982 autumn, extended to Yanjin, Yuanyang, Jiyuan County, nursery area expanded to 1,600 acres, a large area of success Experience.According to the original Yang, Yanjin and other six production units of the survey, sowing per acre 8-10 kg, 2-3 million seedlings production, individual as high as 87,000 strains, after the vaccine seedlings save 8000-10000 Planting the same amount of sowing than the spring, seedlings 3000-4000
