中文摘要:

对墨玉县两种核(桃)麦间作模式小气候因素调查分析表明,小麦间作较单作成熟期推迟4~6 d,群体内CO2浓度和温度分别降低25.33~28.73μmol·mol-1和0.23℃~0.43℃,相对湿度增加4.38~5.32个百分点,产量降低42.2%~74.5%。在间作区域内,拔节到抽穗,是核桃叶幕迅速形成期,遮荫率为52.22%~60.32%,重度遮荫率(光照强度≤1/2空地光照强度)为29.77%~34.09%,至扬花期的遮荫率最大,达52.21%~71.51%,重度遮荫率达37.15%~38.39%,并一直持续到小麦成熟,全期弱影响阶段(光照强度〉1/2空地光照强度)50天左右,强影响阶段(光照强度≤1/2空地光照强度)45天左右,间作小麦群体内CO2浓度和温度大小顺序为顶部〉中部〉底部,距离树行越近,群体内平均CO2浓度越少,平均相对湿度越高,平均温度越低。9 m×3 m的核桃配置的综合小气候条件和产量构成优于6 m×4 m核桃配置,是值得推广的核(桃)麦间作模式。

英文摘要:

The microclimate factors in two intercropping systems between walnut and wheat in Moyu County were studied. The results showed that compared with monocuhure wheat, maturity of intercropped wheat was delayed by 4 - 5 days, CO2 concentration, temperature and yield were decreased by 25.33 - 28.73 μmol. mol- 1, 0.23 ℃ - 0.43℃ and 42.2% -74.5%, respectively, and relative humidity was increased by 4.38- 5.32 percentage points. In the inter- cropping area, the stage from jointing to booting was the rapid formation period for walnut canopy. The shading rate reached to 60.32% - 52.22% and the severe shading rate (light intensity≤ 1/2 light intensity of open space) was 29.77%0 -34.09%. At the stage from flowering to maturity, the shading rate reached to 52.21% - 71.51% and the severe shading rate was 37.15% -38.39%. During the full growth period, duration with the weak influence (light intensity 〉 1/2 light intensity of open space) was about 50 days, while duration with the strong influence (light intensity≤1/2 light intensity of open space) was about 45 days. The order of CO2 concentration and temperature in intercropping wheat groups was top group 〉 middle 〉 bottom. The closer the distance between the tree rows to observation point, the lower the average CO2 concentration in wheat population, the higher the average relative humidity, and the lower the average temperature. Micro-climate condition and yield components for walnut corrfigured with 9 m × 3 m were better than those configured with 6 m × 4 m, a model worthy of being promoted for walnut and wheat intercropping.
