The effects of farming method, rice variety and seedling-raising method were studied on the population growth quality and grain yield of the mechanized transplanting rice by way of three-factor split plot design. The results showed that the no-tillage mechanical transplanting treatment was poorer than the conventional mechanical transplanting treatment in transplanting quality in general, but the former was similar to the latter in population growth quality. In regard to grain yield, the no-tillage mechanical transplanting treatment was lower than the conventional me- chanical transplanting treatment. raising both pot-mat seedling and plastic-tray seedling did not make much difference in population growth and grain yield of mechanized transplanting rice, so both of the seedling-raising methods can be adopted according to practical conditions.

[Objective] The aim was to study the supporting raising technology of Castanea mollissima Blume molecular marker-assisted selection to reduce the cost and time for chestnut breeding.[Method] To find the best cutting method,10 treatments were designed according to transverse diameter and vertical diameter of the chestnut including different cutting ratios in 1/2,1/3,1/4 and different directions about cross cutting,vertical cutting,bevel cutting and two *** germination rate,seedling survival rate and morphological indicators of the treatments were measured;significant difference among them was also analyzed.[Result] 1/3 bevel cutting was the best,which not only could give high germination rate and survival rate,but also could guarantee high quality of nursery stock,which did not grow so differently with the untreated seedlings.[Conclusion] This way can not only reduce too much cost and time for seedling breeding,but also promote the germination of chestnut in advance,which could do much good to production.

This study was conducted for the purposes of reducing consumption of wild resources of Paris polyphylla Smith, satisfying the market demand, saving the production cost, improving utilization rate of forest land, increasing income of foresters and protecting ecological environment. Three types of fores{ land, i.e., the evergreen forest land （China fir forest）, deciduous forest land （walnut forest） and shrub land （honey suckle forest.） were selected, and seeds and cut rhizomes of Paris polyphylla Smith produced in Bamian Mountain, Hunan, were used in the study on understory seedling raising and cultivation techniques. The results showed that： when using different propagation materials, seed propagation could be adopted to reduce the consumption of wild resources and provide a large number of seedlings, and was beneficial to large-scale planting; and when conducing seedling and plantlet raising followed by transplanting and direct seeding and planting using different propagation materials in large-scale understory cultivation, direct seeding/ planting was appropriate for saving save production cost with the advantage of early production. Among the 3 different types of forest land, the best choice was broad- leaved forest land, which could achieve better economic benefit because of con- forming with the ecological habit and growth and development law of Paris poly- phylla Smith.
