红花品种在贵州高原的适应性鉴定与栽培研究

ADAPTABILITY IDENTIFICATION OF SAFFLOWER VARIETIES AND ON CULTIVATION METHOD IN GUIZHOU

经5年试种结果认为贵州的西南部为红花栽培的适宜区。一般适宜区适种品种应以油花兼用的川红一号为主;在低海拔或河谷低热区则应种植含油量较高的AC—1等品种;在1500米以上的局部地区宜种植霞浦等早熟品种。适宜的栽培方法为:10月中、下旬播种,以宽窄行或聚垄耕作法种植,平均行距40厘米左右,亩保苗2.7万株左右。低海拔及热量充足地区以单作为主,中、高海拔地区则可采用间套作方式,实行玉米大豆与红花分带套作,红花收获后再套作甘薯豆类等作物,以提高单位面积总产值。

The results of five years test showed that the area in the southwestern region of Guizhou was adapted to safflower production, and Chuanhong No.l sould be used as main variety in this region. In area with lower elevation and river valley where there is enough heat,it had better to plant Ac-1 for its higher oil content.In the area where the altitude is over 1500 meters early ripening variety Xiapu may be choosed. The suitable ways for cultivation are: sowing date within the middle and last ten days in October, planting in wide and narrow row distence inter-changed or planting on ridges. The rational planting density is about 2.7×10 plants per mu. Sole cropping may be adapted mainly in place with lower elevation and enough heat. Intercropping could be carried out in the area with middle and higher altitute. saffower can be in-terplanted with corn and soybean in different: stripes. After it is harvested sweet potato and beans could interplanted between the corn rows to increase total production value per mu.
