Abstract:

Based on the definite rape varieties in the project area, according to the higherseedrate, the high cost of field management and low utilization of fertilizer and pesticide of the traditional rape in the production. After many years of accumulated experience, Agricultural Technique Extension Station, Long Yang District has a set of synthesized technology integration of high-efficiency production which includes minimum tillage and no-tillage cultivation，the ditching with machine, suitable sowing time, a one-off thinning and ascertaining quantities seedling, simplifying efficient fertilizer treatments, by unifying management to breeding strong seedlings, machinery prevent aphids ,and so on, and screened two early maturity, high quality, high yield and with stronger drought rape varieties-cloud oil hybrid 2, cloud attar 9, which were extended in the rape production areas and similar climate surrounding earlier maturity rape areas in Yunnan, and have lifted expanding of rape planting area. The project established the high-yielding sample rape area of 680 hectares, the average yield was 3478.5kg/hm2, which increased by 18.6% with compared non-demonstration zone, the average yield increased 545.1kg/hm2, the new total output was 370,500kg, the value was 185.33 million yuan，and reduced expenses of 825yuan/ hm2, rape area of 680 hectares may reduce 56.1 million yuan , by the widespread radiation and driving, the average yield increasing of rapeseed was 150-225kg/hm2, which brought very significant economic benefits and social benefits.
