摘要
１９９４～１９９５年对早熟温州蜜柑园进行以产定肥和行间生草树盘覆盖等技术的研究。结果表明，该园达到了预期产量目标，节省了肥料、农药、劳力等投入，提高了肥料的利用率，使土壤中水解氮增加９．０４×１０－６、有效磷增加２．２０×１０－６、有效钾增加１１．２０×１０－６、有效钾增加１１．２０×１０－６、有机质含量增加２．２７％、相对含水量增加１７．５％；同时也提高了早熟温州蜜柑座果率、减少裂果、防治日灼率；平均产量比对照提高。
This paper presented studlies of economic managemnt in early maturing Satsuma mandarin Orchard.The result indicated that fruit yield is increased in the on of asving investment. In soil, hydrolyzed N increased by 9. 04× 10-6.,available P increased by 2. 2×10-6., available K increased by 11. 2× 10-6,organic matter increased by 2. 27 per cent , relative water content was 17. 5 per cent,dehiscent fruit is decreased ,fruit scorching is controlled the fruit yield increased 32. 19 per cent.
