  1. The experiment was conducted to determine the influence of different regulation and control methods of soil moisture, such as plastic film mulching, covering grass under trees, growing grass under trees, irrigating regularly, loosening the soil under trees, on quality of fruit in a non - public nuisance crisp pear garden in the area of old course of yellow river

    摘要以45年生酥梨樹為試材,分析測定塑料薄膜覆蓋、樹盤覆草、自然生草、定期灌水、清耕等不同土壤水分管理措施對土壤水分和酥梨品質的影響,結果表明:塑料薄膜覆蓋和樹盤覆草處理中,土壤含水率比較適宜,且變幅較小,有利於果實生長發育和提早著色,提早成熟,產量和品質較好;其它處理中土壤含水率要麼過高,要麼過低,且變幅較大,酥梨的果實品質也比較差。
  2. The results showed that the soil moisture was moderate for the tree growth by plastic film mulching and covering grass under trees, which had led to higher yield and quality of the fruit than that of other treatments

    因此,在黃河故道區無公害酥梨生產中,建議採取塑料薄膜覆蓋和樹盤覆草方法,此方法操作簡單,便於實施。
  3. Applying the relevant analysis approach of gray system, the authors analyze and assess the average of 9 pasture species on the 12 indexes, including the total covering rate, the hight of grass, green period, reviving period, resisting disease, tiller, length and amount of root, weight of root, weight of leaf and stem, tasty impression, and study the application of gray analysis in the comprehensive assessment

    摘要應用灰色系統中的關聯分析法對9種牧草的總蓋度、草層高度、根系人土深度、青綠期、越冬率、抗病性、分孽數、根長、根數、根重、莖葉干重、適口性等12項主要性狀進行了綜合評估,並討論了灰色分析法在選擇坡耕地水土保持牧草草種綜合評估中的應用。

  5. ( 1 ) in newly - constructed stage and early stage of reclamation, the most important factor of runoff is 30min rainfall intensity. in later stage of reclamation, the most important one is 45min rainfall intensity. and the runoff capacity is the most important influence factor to soil erosion always ; ( 2 ) on the certain degree, loosening surface has an active function to infiltration condition but not to conserve soil ; ( 3 ) the most runoff is formed on platform of stackpile and the soil erosion often happens in the slope ; ( 4 ) stone - soiled dumps have an advantage over soil at respect of erosion resistance so that soil is not adapt in covering slope ; ( 5 ) grass has a better role in conservation of water and soil than arbor in early stage of reclamation ; ( 6 ) arbor - arboret - hemp mix is the best model for conservation

    結果顯示:在未復墾時期和復墾初期, 30min降雨強度對徑流影響最大,復墾後期徑流與45min雨強相關性最強,而徑流量對土壤侵蝕量的影響始終最大;通過疏鬆地表巖土只在一定程度上改善地表的入滲條件,並不能起到保土的作用;平臺為徑流的主要形成區,而土壤侵蝕主要集中在斜坡;土石混排坡的土壤抗蝕性比覆土坡的要大得多,在排土場形成過程中不宜用厚層黃土覆坡;在復墾初期,純草模式水土保持效果明顯好於純喬模式。
