在大量调查研究的基础上,经系统试验,提出了不同年型的施肥技术和播种技术。干旱年份重施磷肥,丰水年份磷、氮并重。氮肥的施用有条件时最好分两次施入,播前施40%,拔节期施60%,或各施50%。采用地膜覆盖膜内穴播时,播期比常规技术延迟15天左右。播种时行距以17cm左右较好。钾肥应成为今后旱地小麦生产中重点考虑的因素。
On the basis of a large number of investigations and studies, through systematic experiments, different types of fertilization and sowing technologies have been proposed. Re-application of phosphate fertilizer in dry years, wet years of phosphorus and nitrogen both. Application of nitrogen fertilizer is best applied in two conditions, sowing 40%, jointing 60%, or 50%. Use of mulching film when the hole-sowing, sowing than conventional technology delayed about 15 days. Sowing spacing of about 17cm better. Potash fertilizer should be the key factor to be considered in dryland wheat production in the future.
