  1. The results are as follows : ( 1 ) based on soil temperature data measured at different time in the field, soil temperature characteristics under plastic mulch were analyzed at four locations : the middle, the edge, in - between the plastic film and uncovered spot ; the characteristics of soil temperature profile from 0 to 25cm depth and the correlation of soil temperatures in different soil layers were studied at different time with and without plastic mulch ; on the basis of analyzing temporal and spatial variations of soil temperature in a corn field, the relations between soil temperature and air temperature were established, and a new method that only uses air temperature to predict soil temperature profile at different time is proposed. the predicted results showed good accuracy

    成果如下: ( 1 )根據大田實測地溫資料,分析了覆膜條件下膜中、膜邊、膜間和揭膜四種處理在早、中、晚三個不同時刻的地溫特徵;分析研究了各觀測時刻覆膜與不覆膜條件下0 25cm剖面地溫的特點及各層地溫間的相關關系;在重點對玉米田地溫時空變化特徵分析的基礎上,首次將覆膜與不覆膜不同時刻觀測的剖面地溫與氣溫建立了聯系,提出了僅根據氣溫資料來預測一日內不同時刻剖面地溫的新方法,預測結果表明其精度較高。
  2. Drip irrigation under mul : h is a new irrigation method, as utiliz e the advance of drip irrigation and plastic film cultivation technique. the conditions influenced crop water requirement are changed in drip irrigation under mulch, thus crop water requirement pattern is different from conventional irrigation forms. it is very useful to research field mulched crops water requirement pattern watering with drip irrigation

    膜下滴灌是地膜栽培與普通地表滴灌相結合的產物,在地膜覆蓋和滴灌的綜合效應下,作物的生長與在常規條件下不同,因此影響作物需水量的一些基本條件都發生了變化,對于膜下滴灌作物需水量和作物系數還需要做進一步研究。
