通過對生長發育規律及對干物質積累、灌溉速率、容重、產量進行相關分析，確定4月30日左右為吉油1號玉米的最佳播種期， 10月5日左右為最佳收獲期。 -
The knowledge model for pre - sowing plan design includes submodels of target yield calculation, variety selection, sowing or transplanting date, population density and sowing rate, fertilization and water management strategy
其中，播前方案設計知識模型包括產量目標、品種選擇、播栽日期、種植密度與播種量、肥料和水分運籌等。 -
The sub - model for design of population density was developed according to the principle of determining boll number from target yield, fruit node from boll number, fruit branch from fruit node and population density from fruit branch by integrating the effects of sowing date, cutout date, effective temperature accumulation above 12, variety type, and fertilizer and water management levels. sowing rate was then decided by integrating the effects of different soil water and salt contents, ph, temperature and sowing style on seedling emergence rate with relative weight method
基於「以產定鈴、以鈴定節、以節定枝、以枝定苗」的原理，同時考慮播種日期、打頂日期、 12的有效積溫、品種株型特性、肥水管理水平差異等因素來確定適宜的種植密度；在此基礎上，應用相對權重法計算土壤含水量、含鹽量以及整地質量和播種方式等多個生態環境因子對出苗率的綜合影響，進而確定播種量。 -
The sowing and seedling raising experiments of castanopsis hystrix seed with different artificial treatments showed 1 - year - old c. hystrix seedling average height and average dbh with the treatments of hastening germination and cutting root were 22. 0 % and 117. 0 % higher than those without the root cutting treatment, respectively, the individual - tree lateral root number increased by 127. 71 %, the afforested survival rate increased by 23. 0 %
摘要對紅錐種子採用不同人工處理的播種育苗試驗表明：紅錐種子經催芽斷根育苗處理后，其1年生苗木平均高和平均地徑分別比無斷根處理的高22 . 0 %和117 . 0 %單株側根數增加127 . 71 % ，造林成活率提高23 . 0 % 。 -
