光照条件、施肥量和播种时期等对几种野生芹菜生长及产量的影响

以拐芹、大叶芹、棱子芹和绿花山芹为研究对象,探讨光照条件、施肥量和播种时期等对几种野生芹菜生长及产量的影响。结果表明:①种源不同,产量不同。在种源相同的条件下,棱子芹林下产量高于全光。②施肥量对大叶芹和绿花山芹产量影响显著。大叶芹在施肥量为4000 kg/亩时,产量最高为1.68 kg/m^2;绿花山芹在施肥量为4000 kg/亩时,产量较高为0.96 kg/m^2。③播种时期对大叶芹产量影响显著,秋播产量明显好于春播。④播种量不同,产量不同。拐芹在播种量为30 g/m^2时,产量最高;绿花山芹在播种量为35 g/m^2时,产量最高为0.45 kg/m^2。

Effects of Light Conditions,Fertilization Amount and Sowing Date on the Growth Yield of Several Wild Celeries

Taking Angelica polymorpha,Pimpinella brachycarpa,Pleurospermum uralense and Ostericum viridiflorum as the research object,the effects of light conditions,fertilization amount and sowing date on the growth and yield of several wild celery were studied were discussed.The results show that:①Seed source is different,and the yield is different.Under the same conditions of seed source,the yield of Pleurospermum uralense under the forest was higher than that of the whole light.②The amount of fertilization had a significant effect on the yield of Pimpinella brachycarpa and Ostericum viridiflorum.The yield of Pimpinella brachycarpa was 1.68 kg/m^2 when the fertilization amount was 4000 kg/mu;When the fertilization amount was 4000 kg/mu,and the yield of Ostericum viridiflorum was 0.96 kg/m^2.③The sowing period had a significant effect on the yield of Pimpinella brachycarpa,and the yield in autumn was significantly better than that in spring.④The seeding rates was different,and the yield was different.When the seeding amount of Angelica polymorpha was 30 g/m^2,the yield was the highest;when the seeding amount was 35 g/m^2,the yield was up to 0.45 kg/m^2.
