摘要: 陡坡地灌桑垄槽栽培研究结果,免除土壤侵蚀的危害,其50cm、100cm土壤中,比对照区持水量高10.20%~33.67%、8.27%~65.37%,含全氮率为对照的90%,含全磷率高2.9%、26.2%,含全钾率高3.18%、8.01%,而水解氮均为对照的61.5%,速效磷高较对照39.02%、97.72%,速效钾为对照的91.48%、92.54%。公顷产桑叶量和蚕茧量均较对照高5~10倍,经济效益较对照高11.88倍。

Abstract: The study results of the ridge trough culture of bush mulberry on steep sloping land show that the calamities of soil erosion are prevented. In comparison with the contrast area, at the depths of 50cm and 100cm, the soil water content of the managed land is 10. 20%~33. 67% and 8. 27%~65. 37% higher respectively, the total N is 90% of the contrast area, the total P is 2. 9% and 26. 2% higher respectively, the total K is 3. 18% and 8. 01% higher respectively, the hydrolysed N is 61. 5% of the contrast area, the available P is 39. 02% and 97. 72% higher respectivley and the available K is 91. 48% and 92. 54% of the contrast area respectively. The per heatare leaf and cocoon production is 5~10 times higher than that of the contrast area. The economic benefit is 11. 88 times higher than that of the contrast area.
