Abstract:

Ef fect of compomnent of yield, LAI, dry mat ter w eig ht , f low er and po d w eigh t onthe so ybean va riety " Huaido u 4" w ere studied under dif ferent lev els of sowing stag e,densi ty and ferti li zer, The g ood phy siological bases fo r high- yield ty pe of "Huaidou 4"is that LAI lies at 2. 0- 2. 1 at t rue leaf stag e, and maxium LAI sho uld become 4. 1- 5.0 a t blooming stag e, and maintain 3. 5- 4. 2 at pod- fi lling stage. Dry mat ter accumulationand disst ribution should have eno ug h souce. Branches lie around 2. 8- 3. 5, Thenumber o f pods per plant around 30, the seeds per pod is 2. 2, and the w eight of 100seed is 22 g ram. The cultiv atio n mode for the go od phy siological bases i s tha t so ybeanshould be sowed in 1- 15th of June, densi ty is 175, 000 plants per mu, amount o f topdressing fertilizer in ini tial flow ering stage is 4. 0kg per mu, and foliag e dressing w ouldbe applied a t the pod fi lling stag e i f needed.
