摘要

陡坡垄槽栽培矮化果桑效益研究结果表明:产桑椹汁较对照提高5.25倍;土壤侵蚀较对照(0.799～10.8t/亩)降至零(无侵蚀);50与100cm深土壤全氮含量为对照的90%和相同;全磷含量提高2.9%和26.2%;全钾含量提高3.18%和8.01%;水解氮均为对照的61.5%;速效磷提高39.02%和97.72%;速效钾为对照的91.48%和92.54%;经济效益较对照高5.55倍。

Abstract

The results of the show that compared with control experiement

mulberry juice production increased to 5.25 times

soil erosion amount increadsed from 0.799-10.8 tonper mu(1/15 of ha)to 0 ton/mu.Soil utrient concentration in both depth of soil profiel of to 50 cm and 0 to 100cm is 90% and 100% of the control ones respectively for total N

102.9% and 126.2% for total P

103.18% and 108.01% for total K

61.5% and 61.15% for available N(hydiolysed N)

139.02% and 197.72 for available P and 91.48% and 92.54% for available K.The benefit of the cultivation is 5.55 times of control one.
