气温变化对浙江临安区雷竹笋产量的影响研究
|
摘要
以杭州市临安区1989—2016年雷竹笋产量、产值及气象站点的月气温数据,研究了临安区雷竹笋产量与气温的相关性。结果表明:临安区覆盖笋和自然笋的年平均产量分别为16.78、7.61 t/hm~2,年平均产值分别为12.07、1.34万元/hm~2;临安区年均气温上升幅度达0.21℃/10 a;雷竹笋产量与上年度9月、10月、12月和当年3月份气温的相关性达显著水平(P<0.05),覆盖笋产值与上年度10月最低气温的相关性也达显著水平(P<0.05)。
The correlation between the yield of Phyllostachys violascens shoot and air temperature in Lin'an District of Hangzhou was studied by using the monthly temperature data from 1989 to 2016 as well as the shoot yield and output value. The results showed that the average yield of mulched bamboo shoots and naturally growing bamboo shoots was 16.78 t/ha and 7.61 t/ha, and the annual mean output value was 120 700 and 13 400 Yuan/ha, respectively. The annual average temperature increased by 0.21 ℃/10 a in Lin'an. The correlation between Phyllostachys violascens shoot yield and the temperature in September, October and December of the previous year and March of that year was significant(P<0.05), and the correlation between the output value of,mulched bamboo shoots and the temperature in October of last year also reached a significant level(P<0.05).
