摘 要：
将青海省历年审定的早熟白菜型、中晚熟白菜型和特早熟双低甘蓝型杂交油菜在青海省温暖灌区麦后进行试种试验,筛选出早霜来临前安全成熟的高产优质品种青杂4号,而后针对该品种开展了不同播期、播种方式、密度、施肥水平及化学除草等麦后复种的丰产栽培技术研究。结果表明,青杂4号作为复种油菜7月20日前浅耕后播种,密度12.0×105~12.5×105株/hm2,磷酸氢二铵用量340~360 kg/hm2,尿素用量190~210 kg/hm2,油菜5叶期用10.8%高效盖草能和28.6%氨氯吡.二氯吡AS各500倍稀释液进行化学除草,复种产量可以达到1 500 kg/hm2。

摘 要：
Through the experimental platting of early-maturing Chinese cabbage type hybrid rape,mid-late-maturing Chinese cabbage hybrid rape,and special early-maturing and double low cabbage type hybrid rape authorized in Qinghai province after wheat in warm irrigation area of Qinghai province,the rape variety,Qingza no.4,which could mature safely before early frost,was screened out.Then some high-yield cultivation techniques of different sowing time,seeding method,seeding density,fertilization level,chemical weed control and soon,about this variety after wheat multiple cropping were studied.The results showed that when shallow tillage-sowing before July 20,the dose of diammonium phosphate and urea were 340 ~360 and 190 ~210 kg/hm2,the densities was 12.0 ×105~12.5 ×105 sprouts/hm2,and chemical weeding with 500 times diluents of 10.8% of high performance Gaicaoneng and 28.6% of ammonia.chloride AS at 5 leaf stage,the yield of Qingza no.4 could be up to 1.5×103kg/hm2.
