不同階段的不同程度受旱對水稻生長發育的影響不盡相同，相同程度受旱對產量影響最大的階段為拔節孕穗期；抽穗開花期次之，在分蘗期和灌漿期實施一定程度的水分虧缺不會對產量構成較大影響。 -
Pot experiments materials were carried out to determine the cold hardiness of six varieties cultivated popularly in henan, named bainong aikang 58, handan 6172, yumai 49, yumai 54 - 99, yumai 18, yumai 2, under controlled temperature at seedling stage, over - wintering stage, green returned stage and jointing stage for identifying
摘要以河南省主推品種百農矮抗58 、邯鄲6172 、豫麥49號、豫麥54 - 99系、豫麥18號、豫麥2號6個小麥品種為材料，通過控制各生育時期的生長溫度，分別測定苗期、越冬期、返青期和拔節期各品種的抗寒能力。 -
The results indicated : ( 1 ) during the jointing stage of winter wheat, the differences of catalase activity among different measures of soil water utilization are significant in shallow soil, in which the catalase activity of furrow planting with straw mulch is the highest and that of row - spacing - reduced and close planting is the lowest ; ( 2 ) the trends of catalase activity versus depth are almost the same for different treatments, looking like an inverse s ; ( 3 ) for furrow growing without mulch, the activity of soil catalase in the furrow is higher than that in the ridge ; ( 4 ) soil catalase activity reflects some effects from different techniques of soil water utilization and may be used as a indicator for micro - eco - environment in the fields
初步分析得出： （ 1 ）冬小麥拔節期，採用不同土壤水利用技術的冬小麥田淺層土壤過氧化氫酶活性差異明顯，以溝播不蓋秸稈處理的過氧化氫酶活性最強，縮行密植處理的最弱； （ 2 ）土壤過氧化氫酶活性隨深度的變化趨勢大體一致，呈反s形； （ 3 ）溝播不蓋秸稈處理溝中土壤過氧化氫酶活性明顯高於壟上； （ 4 ）土壤過氧化氫酶對於田間微生態環境具有指示作用，在一定程度上反映了土壤水利用技術對微生態環境的影響。 -
Moreover, milking wheat should be irrigated since the weather is very drought and short of rainfall from maize interplanting to jointing stage
另外，灌漿小麥應當灌水，因為玉米套種至拔節期氣候乾燥少雨。 -
The other 50 % and 10 % of n will be dressed in peak jointing stage and milking stage along with irrigation
50 %的氮在拔節高峰期、 10 %的氮在灌漿期隨水追施。 -
Wheat fertilization mainly in basal, all organic manure, p and k and half of n fertilizers are applied at plowing, the rest n fertilizer dressed in jointing stage along with irrigation
小麥施肥主要為基肥，全部有機肥、磷、鉀和一半氮肥翻地時施入，其餘氮肥在拔節期隨灌水追施。 -
For this natural created almighty region, our forefathers have been cultivated the soil and developed agriculture in sorthern shaanxi province as early as stone age and the region is one of the areas in which chinese agricultural developed in its early stage, and it also serves a cradle for chinese civilization. the characteristic features, bridge jointing the south and the north as well as the channel for the east and the west, makes the region an unequal key points function in chinese agricultural exploitation, and on the other hand, the economy, society and culture of this region has its significance for our study
由於所處的地理位置和自然條件，該地區自先秦時期就成為中原文化與巴蜀文化的交匯之地，因此，陜南的農業開發較早地呈現出稻作農業與旱作農業兼營的特點，春秋戰國時期，隨著農業生產技術的提高和區位交通的發展，陜南地區的傳統農業開始出現，成為了農業開拓、聯系南北的中心地帶，戰略地位凸現，先後被楚、秦反復爭奪並進行早期的農業開發。
