杂交油菜“秦油二号”也和其他作物一样,加强越冬苗期的田间管理,争取年前棵大、苗壮是夺取油菜丰收的基础。要达到这个目的,必须针对“秦油二号”的特性和各地不同情况,因地制宜地采取相应技术措施。一、及时间定苗,加强中耕。直播油菜出苗后半月左右,长出3~4片真叶时进行间苗;5~6片真叶时,按规定密度定苗。同时剔除小苗、弱苗。随后浅锄松土保墒,以利提高地温。年里一般要锄2~3次。移栽田块待返苗活棵后进行中耕锄地。二、针对苗情,早施腊肥。“秦油二号”苗期就表现出较强的杂交生长优势,必须满足它对养分的需要。在施足各种底肥的基础
Hybrid rapeseed “Qinyou 2” and other crops, like, to strengthen winter field management seedlings, for years ago, large tree seedlings is to win the harvest of rapeseed basis. To achieve this goal, it is necessary to adopt the corresponding technical measures according to local conditions in light of the characteristics of Qinyou No.2 and the different situations in different places. First, and time Dingmiao, strengthen cultivation. Live rapeseed after about half a month, grow 3 to 4 true leaves when the Miao Miao; 5 to 6 true leaves, according to the required density Dingmiao. At the same time remove small seedlings, weak seedlings. Followed shallow hoe soil moisture, in order to enhance the ground temperature. In general to hoe 2 to 3 times. Transplantation plots to be returned after seedling hoeing hoe. Second, for Miao Qing, early Shi Lan fat. “Qinyou 2” showed a strong hybrid growth advantage at the seedling stage and must meet its nutrient needs. In full application of a variety of base fertilizer
