杂交糯高粱“泸糯8号”双季高产栽培技术研究

Studies on Cultivation Techniques of Hybrid Sorghum Lu Nuo 8 with Glutinous

试验表明,川东南育苗移栽区净种栽小春地以4月上旬播种(如栽空地或预留行,则可在3月上中旬播种),6叶期移栽(苗龄25～30d),净种每公顷植90000～120000株,每公顷施化学纯氮150～187.5kg可获得较高产量。在再生高粱栽培上,在头季收割前10～15d每公顷施150～225kg纯氮作促芽肥,头季收获时用快刀砍杆,留桩高度以保留顺1节～顺3节为宜,头季收后5d,每公顷施150kg纯氮作发苗肥,可获得较的再生高粱产量。

We studied cultivation techniques of hybrid sorghum Lu Nuo 8 with glutinous, The results as follows： Lu Nuo 8 will got high yield that was sowed the first ten days in April in southeast with wheat field only for sorghum, was sowed the first ten days in March in southeast with blank field or the field with wheat/ corn for wheat/sorghum, and translated at 6 leaf with 25-30 days old, 90000-120000 plants per hm^2, and used 150-187.5kg N per hm^2, Lu Nuo 8 hope to get good grain yield for ratoon sorghum, 150-225kg N per hm^2 was used 10-15days before first crop cut, and the stem was cut above two nodes when the first crop was harvested. Then 150kg N per hm^2 will be used after 5 days first crop was harvested.
