摘要

采用正交试验设计

通过田间试验

研究了滴灌条件下核桃的灌溉制度。研究表明

不同水分下限处理的核桃耗水总量为711.77～814.38 mm

生育期内各处理各月的日耗水强度4月为3.57～4.18mm/d

5月为3.78～4.87mm/d

7月达到最大值5.9～7.35mm/d

8月为3.6～4.46mm/d。综合分析产量、蛋白质含量、脂肪含量及出仁率

结果认为

开花期、果实膨大期及硬核期的土壤水分下限指标分别为60%

60%和50%

全年灌水12次

灌水定额为680m

/hm

。

Abstract

Irrigation schedule for walnut tree under drip irrigation was studied through a field experiment with orthogonal design method. Results showed that the total water amount was between 711. 77 and 814. 38mm for different lower limit treatments of soil moisture. In the growing period

daily water consumption for the treatments was 3. 57～4. 18mm/din April

3. 78～4. 87mm/d in May

5. 9～7. 35mm/d in June and July

being highest

and 3. 6～4. 46mm/d in August. Comprehensive analysis of yield

protein

fat and kernel rate showed that the lower limits of soil moisture were 60%

60% and 50% in flowering stage

fruit expan-ding stage and stone hardening stage

respectively. Suitable irrigation was 12 times one year and the quota of irrigation was 680m3/hm2.
