在辉县市北部太行山浅山区，有许多不规则的果、农间作园，其中以山楂－小麦间作园较为普遍，于春末、夏初，干旱、高温、多风灾害严重期，对山楂－小麦间作园和山楂不同行距密度与小麦地同步进行小气候测定，结果表明：气温和土温、温度日较差、风速均随山楂种植密度、单位面积覆盖度增大而减少，空气湿度也随树体加密而增大。山楂行距６ｍ、８ｍ、１０ｍ、对照日内最高气温分别是２８．７、２９．０、３１．１和３２．９℃，０ｃｍ地温日较差分别是８、１１、１７和２１℃，１６０ｃｍ高处上平均风速分别是０．７、０．９、１０．５和１１．７ｍ／ｓ．空气相对湿度，山楂－小麦间作园分别增加（与对照相比）７．６％、４．７％和２．２％。
There are many irregular fruits in the shallow mountainous area of Taihang Mountain in Huixian City. Among them, hawthorn-wheat intercropping garden is more common. In late spring, early summer, drought, high temperature and windy disastrous period, hawthorn- The results showed that temperature and soil temperature, temperature day were poor, and the wind speed decreased with the planting density of hawthorn and the coverage per unit area increased, and the air humidity also changed with the tree Body encryption and increase. Hawthorn row spacing 6m, 8m, 10m, the highest temperature control day were 28.7,29.0,31.1 and 32.9 ℃, 0cm ground temperature day difference is 8,11,17 and 21 ℃, 160cm height The average wind speed was 0.7, 0.9, 10.5 and 11.7 m / s, respectively. Air relative humidity, hawthorn - wheat intercropping increased (compared with the control) 7.6%, 4.7% and 2.2% respectively.
