Abstract(298) [PDF 453KB](63)
Abstract:
Rice planting mechanization mode that suitable for Yuejin farm near stage and in the future was explored by studying several existing planting forms in Yuejin farm.Comparative tests between mechanized-direct seeding and artificial sowing showed that： by mechanized-direct seeding，small environment of rice growing was improved，growth of rice tillering was promoted，rice panicle rate was increased and disease resistance of rice was improved，the yield of rice was increased，also it was conducive to the removal of malignant weeds.Main cause for increasing of yield which up to 5.44％ was that grain number per panicle was significantly improved in case of mechanized-direct seeding when compared to artificial sowing.By comparing yield analysis of directing seeding and mechanized-transplanting during three years in Yuejin farm，it was showed that overall yield of mechanized-transplanting was slightly higher than that of directing seeding mainly because that it was easier for mechanized-direct seeding to get spike seedlings and spike seedlings got by mechanized-transplanting was unstable.By analyzing 8 cost structure items in rice planting，it was showed that cost could be reduced by 20% by mechanized-direct seeding compared to mechanized-transplanting，and considerable economic benefits could be got by choosing mechanized-direct seeding.Practice showed that advantages of mechanized-transplanting in Yuejin farm was not in increasing of yield of rice but in increasing regularity and fullness of rice grain filling，improving quality and purity of rice seed propagation and controlling weed damage.To sum up，in the near future，mechanized-direct seeding and mechanized-transplanting would fully substitute artificial sowing，mechanized-direct seeding is main form of mechanized rice planting，and mechanized-transplanting is auxiliary form which mainly used for breeding；as continuous development of rice hill-dropping machine，mechanized- hill-dropping would become main seeding form，which would meet requirements of rice seed propagation and seed quality and achieve the objectives of stable output，reduced cost and increased efficiency.
