Table 1. new two excellent 223 seasons and regeneration season growing process (Chi Dong town, Qichun County, 2012)
Found out by table 2, new two excellent 223 in transplanting situation first rice crop average yield per mu 651.0 kilograms, regenerate season average yield per mu 380.0 kilograms after first rice crop mechanized harvest, new two excellent 223 when entire mechanization per mu yield reach 1031.0 kilograms, it is achieved that realize Oryza sativa L. " a kind of two receive " and cross ton-grain. Compared with regenerating season yield with after first rice crop hand harvest, the yield regenerating season after mechanized harvest increases by 13.7%, the too big too heavy crawler belt of mainly current harvester of tracing it to its cause is too wide, it is serious that rice stubble rolls disappearance repeatedly, the root and stem of certain plants percentage of earbearing tiller is made to reduce 44.7% and substantially postpone through rolling part period of duration, the Basic Seedling of extreme influence Herba Oryzae Reproductii and yield. In view of problem above, the transformation and upgrade of traditional rice harvester are in progress. Application entire mechanization " a kind of two receive " technology mode, it is achieved Oryza sativa L. increases production more than 25% than the single harvest rice, and benefit increases by 20%, and mu increases income more than 200 yuan; Increasing production about 5% than double cropping of rice, benefit increases by more than 30%, and mu increases income and economizes on spending more than 500 yuan.
