蓖麻饼粕对茄子和红干椒的肥效研究

The Research of the Fertilizer Efficiency of Castor Bean Meal to Eggplant and Red Pepper

蓖麻饼粕含较高的有机质和氮磷钾,还含有充足的微量元素.把蓖麻饼粕作为有机肥料施用,运用直播的方式栽培了茄子和红干椒.试验结果表明施用蓖麻饼粕的茄子和红干椒处理区产量与施用化肥处理区无明显差距,并且蓖麻饼粕处理区的有机质残留量明显增加,土壤酸碱度和容重接近了植物生长发育的适宜范围.

Castor bean meal contains high organic matter, N, P, K and abundant trace elements. In this research, the eggplant and the red pepper were planted with the castor bean meal fertilization under the way of direct sowing. The resuits indicated that there was no significant difference in the output between the castor bean meal fertilizer zone and the normal one. An obviously increase in the residual amount of the organic matter in the castor bean meal fertilizer zone. The PH and the bulk density of the soil approached to the appropriate range of plant growth and development.
