啤酒大麦80-15栽培技术的探讨

1986～1989连续三年对啤酒大麦80-15的栽培技术进行了探讨.结果表明:1.每亩18-20万苗为宜,播期在10月27日至11月3日,亩施氮磷钾配合分别为7.5公斤、5公斤和5公斤.2.氮肥分施有利于增产.基肥、腊肥和拔节肥的氮肥施用比例分别为60%:20%:20%.3.播期越晚且密度越大.条纹病发生越重. 另外,本文还探讨了氮磷钾肥对80-15大麦产量构成因素的影响.

CULTURAL TECHNIQUES OF MALTING BARLEY '80-15'

Cultural techniques of malting barley 80-15 had been studied inHefei in 1986-1989. The results are as follows: 1.At a proper seeding density(180 000-200 000 seedling per mu) and pr-oper sowing time (27.Oct.-.Nov.) in combination with the applica-tion of N (7.5kg/mu) P (5kg/mu) K (5kg/mu) fertilizers that maltingbarley 80-15 should be obtained higher yield, respectively. 2.Split application of nitrogen fertilizer had given the high yieldsthan application of all the fertilizers as basal treatment. We consideredthat split application of nitrogen (66% at sowing time, 20% at dura-tion of hibernation and 20% at elongation stage) would be most favo-rable for obtaining the high yields. 3.In the case of different planting date × different sowing norm, themore we plant later and sow densely, the more barley is heavily da-maged by stripe disease. In addition, the effects N, P, K fertilizers on the yield componentof malting barley 80-15 had been studied.
