沙打旺抗寒力强,一般说从早春到初秋都可以播,种只要霜冻前地上部长出3~5片真叶,就能够安全越冬.但是,播期早晚对产量影响很大,播期越晚,鲜草产量越低,甚至当年无产量.据我们在沈阳市东陵试验,4月底或5月初以前播种的,秋天株高1米左右,亩产鲜草2,700~2,800斤;6月初到6月中旬播种的,秋天株高50~80厘米,亩产鲜草1,400~1,800斤;7月播种的,秋天株高仅15~30厘米,亩产鲜草200~600斤.晚播对第二年的生育
It is generally said that it can be sowed from early spring to early autumn, and as long as 3 to 5 true leaves are grown on fronts before frost, it will be safe to wintering. However, the sowing date has a great impact on the yield, and the sowing date The later the fresh grass yield is lower, or even no current year.According to our test in Dongling, Shenyang, before the end of April or early May, about 1 meter tall plant in autumn, yielding 2,700-2,800 kg of fresh grass per mu; early June Planting in mid-June, autumn plant height of 50 to 80 cm, 1,400 to 1,800 kg of fresh grass per mu; sowing in July, the autumn plant height of only 15 to 30 cm, 200 to 600 kg per mu fresh grass.
