油研50轻简高效栽培技术研究 Ⅰ.不同种植方式的产量及经济效益

Simple and Efficient Cultivation Technique of Youyan 50,a New Hybrid Rape Variety Ⅰ. Yield and economic benefit of different planting patterns

为摸清甘蓝型优质杂交油菜新品种油研50适宜的配套轻简高效种植方式及相应的技术措施,设置6种不同的种植方式对其配套高效种植技术进行了初步研究。结果表明:普通育苗移栽(对照)的产量最高,但净收益最低。其他处理的产量均较对照有不同程度的减产,但净收益均比对照高,增加的倍数不等,其中,整地撒播增加的最多(11.88倍),其次是整地条播和免耕移栽处理,增加的倍数分别是8.89倍和8.79倍,稻桩免耕窝播和整地窝播增加的倍数略低,且这2个处理的产量较低。因此,整地撒播、整地条播和免耕移栽都可以作为油研50的轻简高效栽培技术因地制宜地加以推广应用。

Six different planting patterns were tested in high yield cultivation of Youyan 50,a new hybrid rape variety,to study the appropriate simple and efficient planting patterns and relative technological measures.The results showed that the yield of the seedling transplanting pattern（CK） was the highest but its net income was the lowest,the yield of other planting patterns reduced to varying degrees compared with CK but the net income was higher than CK,the yield of the broadcast sowing with ploughing pattern,strip sowing with ploughing pattern and seedling transplanting with no-tillage pattern was 11.88 times,8.89 times and 8.79 times that of the seedling transplanting pattern（CK） respectively.Therefore,the broadcast sowing with ploughing pattern,strip sowing with ploughing pattern and seedling transplanting with no-tillage pattern can be popularized in cultivation of Youyan 50 in the light of local conditions.
