不同采收时期对豌豆苗产量性状的影响

以2种不同株型的7个品种，在不同时间采收豌豆苗，结果表明，采收豌豆苗促进分枝数增加2--5．8倍，在接近豌豆开花期采收分枝数最少；采收抑制主茎高度，在D3期采收豌豆苗植株的主茎高度影响最小；不同时间采收使茎的总节数差异显著达到1．9～8．8倍；同一品种内不同采收期对分枝数，主茎高度，茎的总节数，豌豆嫩荚产量都表现极显著差异；4个时期采收到的豌豆苗的量在高秆和矮秆品种以及在矮杆品种内均表现出显著差异，豌豆苗的露地最佳采收时期在D3期即四月上旬。

Effects of Harvesting Pea Sprout in Different Times on Yield Characters

Seven pea varieties belonged to two plant types were adopted, and their sprouts were harvested at different times,to investigate the effect of havesting on yield eharouters of pea. Results indicated that havesting pea sprout could increase the number of branoh,inhibit the caulis height. When the pea was harested at anthesis and D3 stage,it got the least branch and caulis height. Different harvesting time resulted in distinct difference among branch numbers, caulis height,total nodes,and immatare pod yield within the same variety. The yield of pea sprout harvested at four stage between high and short stalk varieties was different,and the best harvesting time of pea sprout in field was at D3 stage, whieh was the first ten days of April.
