箭筈豌豆腐解对土壤及枸杞生长的影响

Influence of common vetch decomposition on soil nutrient and growth of wolfberry

以箭筈豌豆、宁杞7号为材料,研究了箭筈豌豆腐解对枸杞种植土壤养分及枸杞生长的影响。结果表明:箭筈豌豆容易腐烂,腐解90 d时,土壤中的全氮、全磷、全钾、碱解氮、速效磷、速效钾含量都显著增加,以播种量80 kg/hm2的效果最为显著;80,120 kg/hm2处理能显著促进二年生枸杞的营养生长。箭舌豌豆—枸杞间套作有利于枸杞生长。

Common vetch and No .7 wolfberry cultivar were used as materials to test the influence of decomposition of common vetch on soil nutrient and growth of wolfberry .The results show that com-mon vetch is easy to decay .After decomposed 90 d, the soil total N, total P, total K, alkaline hy-drolysis N, available P and available K content were increased significantly .Either 80 kg/hm^2 or 120 kg/hm^2 seeding rate can obviously promote plant vegetative growth of the 2 -year wolfberry. The most effective seeding rate was 80 kg/hm^2 .Intercropping of leguminous green manure and wolf-berry is favor of wolfberry growth .
