第一，20厘米+40厘米种植方式。滴灌带放置在20厘米窄行中，滴灌带一管2行，滴灌带间距60厘米，灌水均匀，群体发育好，产量高。适宜土壤较肥沃的田块。
First, 20 cm + 40 cm planting. The drip belt is placed in a 20 cm narrow row, with one tube and two rows of drip belt. The distance between drip belts is 60 cm. The irrigation is uniform, the population is well developed, and the yield is high. It is suitable for fields with rich soil.
第二，15厘米+15厘米+15厘米+30厘米种植方式。滴灌带放置在30厘米宽行中，滴灌带一管4行，滴灌带间距75厘米，灌水较均匀。适宜土壤较瘠薄的田地。
Second, 15 cm + 15 cm + 15 cm + 30 cm planting. The drip belt is placed in a 30cm wide row, with one tube and four rows. The distance between the drip belts is 75cm, and the irrigation is relatively uniform. It is suitable for the fields with poor soil.
滴灌栽培播种以穴播或半精量播种为主，应根据不同的行距配置、留苗密度，确定株距。春油菜生长季节短，要求密度大，冬油菜密度较小。直播油菜一般20000~30000株/667米2，移栽冬油菜一般8000~10000株/667米2。
According to different row spacing and seedling density, plant spacing should be determined. The growth season of spring rape is short, and the density of winter rape is small. In general, 20000-30000 plants / 667 m2 of direct seeding rape, and 8000-10000 plants / 667 m2 of transplanting winter rape.
