【摘要】 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。更多还原

【Abstract】 Fertilzing and planting techniques for wheat in different years with various rainfallwere put forward on the basis of field investigation and systematic experiments. Phosphorous fertilizer should be mainly applied in dry year while both phosphorous and nitrogen fertilizer shouldbe mainly applied in the wet year. It is suggested that nitrogen fertilizer be applied for two times,that is 40% before sowing and 60% at the shooting stage, or 50% for each time. When plasticfilm is mulched, sowing should be POstponed for 15 days compared with conventional technique.The suggested row spacing for wheat sowing in the rain fed area is 17cm rather than 20cm.更多还原
