果园生草条件下土壤与近地层空气温湿度特征研究
Study on the Air Temperature and Humidity Characteristics of Soil and Near-surface Layer Under Grass Growing Conditions in Or-chard
摘要
Abstract
[Objective]To clarify the variation characteristics of soil and near-surface air temperature and humidity under different grass spe-cies,and to provide theoretical basis for the promotion of grass technology in orchards.[Method]Based on the design of randomized field ex-periment,four kinds of drought-resistant and cold-resistant grass species(Lolium perenne,Medicago sativa,Festuca arundinacea,Vicia sepi-um)were selected,combined with natural grass and clear tillage as the control,to analyze the characteristics of soil and air temperature and humidity changes in orchard under different grass varieties and different seasons.[Result]In the spring and summer high temperature periods,the soil water content of Medicago sativa and Vicia sepium planted in 0-40 cm soil under grass cultivation was higher;the overall temperature reduction rate of Vicia sepium,Medicago sativa and Festuca arundinacea in 0-20,>20-40 and>40-60 cm was relatively high.In the summer high temperature period,planting Medicago sativa or Vicia sepium could reduce the near-surface air temperature by 1.5℃and increase the air humidity by more than 11.82%.[Conclusion]Compared with clear tillage,interrow sowing of Medicago sativa and Vicia sepium can significant-ly increase soil and near-surface air humidity,and decrease soil and near-surface air temperature.In spring,orchard grasses regulate the growth and development of fruit trees mainly by reducing the temperature difference between day and night.In the summer high temperature period,orchard grass mainly reduces the adverse effects of high temperature and drought on the growth and development of fruit trees by inhibi-ting soil water loss and increasing air humidity.关键词
