1986年,牡丹江垦区为了繁殖小麦苗头品种,交给八五一○农场科研站0.35公斤种子,精选后剩0.3公斤,播种1亩地,结果收获种子208公斤,繁殖倍数达594.3倍。主要技术措施: 1.选种。对这样少量的高繁种子,我们进行人工粒选。选后的种子子粒饱满、整齐一致,播前4天,用克菌丹湿拌种,保证了出苗齐、足、匀、壮。 2.选地。选择地势平坦秋翻的豆茬地。黑土层20～30厘米,有机质含量3.9%,水解氮7.2mg/100克土,速磷5.16mg/100克土,播种前春耙两遍,耪三遍,地平土碎。人工开沟施肥后单粒点播,行
In 1986, Mudanjiang reclamation area in order to breed wheat seedling varieties, to 0.355 farm research station 0.35 kilograms of seeds, after the selection of 0.3 kg, sowing 1 acres of land, the results of 208 kg of seeds harvested, breeding multiples of 594.3 times. The main technical measures: 1. Selection. For such a small amount of high complexity of the seeds, we carry out artificial selection. Seeds after election seeds full, neat and unanimous, 4 days before sowing, with Ketjen wet dressing, to ensure the emergence Qi, enough, uniform and strong. 2. Choose the site. Select the flat autumn fall stubble field. Black soil 20-30 cm, organic matter content 3.9%, hydrolyzed nitrogen 7.2mg / 100 grams of soil, phosphorus 5.16mg / 100 grams of soil, rake two times before sowing in spring, 耪 three times, the level of soil broken. After artificial ditching and fertilization single-on-demand, line
