1992年讷河市大面积推广了马铃薯应用甘薯增产菌新技术,并取得了显著的增产、增收效果。534hm~2马铃薯应用了此项新技术,共增产马铃薯6814.9t,增收81.8万元。甘薯增产菌是北京农业大学研制的一种新型生物菌肥。其使用方法:①拌种:每公顷用甘薯增产菌150g,对适量的清水后均匀地喷在1500kg种薯表面,荫干1～2天后即可播种。②喷雾:在马铃薯出苗后至分枝前1hm~2用甘薯增产菌150g,对225kg清水,进行全株喷雾。据8月10日定点调查,应用甘薯增产菌拌种的马铃薯较对照平均株高增加1.2～3.3cm,茎粗增0.24cm,叶长增1.7～2.3cm叶宽增0.8～1.2cm,根数多2.2～3.7条,平均每株鲜重增加29.3～
In 1992, Nehe City, a large area to promote the potato application of sweet potato stimulation of new technology, and achieved significant increase in production and income. 534hm ~ 2 potato application of this new technology, a total increase of 6814.9t potatoes, an increase of 818,000 yuan. Sweet potato yielding bacteria is a new type of biological fertilizer developed by Beijing Agricultural University. The use of methods: â ’¢ seed dressing: sweet potato yield per hectare by bacteria 150g, after the right amount of water evenly sprayed on the 1500kg seed surface, shade 1 to 2 days after sowing. ② spray: After the emergence of the potato to the branch before 1hm ~ 2 with sweet potato yield bacteria 150g, 225kg of water, the whole plant spray. According to the survey conducted on August 10, the average potato height increased by 1.2-3.3cm, the stem diameter increased by 0.24cm, the leaf length increased by 1.7-2.3cm, the leaf width increased by 0.8-1.2cm and the number of roots was 2.2 ~ 3.7, the average fresh weight per plant increased by 29.3 ~
