摘要
在田间试验,调研考察,资料分析的基础上,研究了黄花菜、百合、啤酒大麦等特色作物气候生态适应性,确定了3种特色作物的气候生态区划综合指标体系。即:黄花菜取4—8月上旬≥0℃积温、降水量、6—7月日照时数作主导指标及产量作辅助指标;百合选取年≥0℃积温、无霜冻期和花期至鳞茎膨大期(6月中旬至8月上旬)降水量作主导指标,平均产量作辅助指标;啤酒大麦选取年≥0℃积温、幼穗分化期(5月下旬至6月上旬)和灌桨期(6月下旬至7月中旬)平均气温作主导指标,以及产量和品质作辅助指标。对3种特色作物分别进行最适宜、适宜、次适宜、可种植和不宜种植共5级气候生态适生种植的区划,并提出提高气候生态资源利用途径,为种植基地建设、发展规模生产、提高经济效益提供科学的决策依据。
Based on field experiment,investigation and research,as well as analyses of the experimental data of eco-climatic adaptability for citron daylily,lily and beer barley,the integrated index system of eco-climatic zoning is determined.The results show that the primary indexes for citron daylily are ≥0℃ accumulated temperature from April to the first ten days of August,rainfall accumulated sunshine-hour from June to July,and the supplementary index is the average yield;Lily's major indexes are ≥0℃ annual accumulated temperature,frost-free season and rainfall from bloom to caudex becoming large (from the middle ten days of June to the first ten days of August),and similarly,the supplementary index is the average yield;for bee barley,the major indexes are ≥0℃ annual accumulated temperature,the average temperature of spike polarization's phase (from the last ten-day of May to the first ten-day of June) and grouting phase (from the last ten-day of June to the middle ten-day of July),and the supplementary indexes are the average yield and quality.The planting zoning of climatic-ecological adaptability of the three characteristic crops is divided into 5 grades, i.e. best suitable,suitable, hypo-suitable,just suitable and unsuitable regions.At the same time,the way to raise the utilizing efficiency of eco-climatic resources is also presented,which offers a scientific basis for building planting base,developing production on a large scale and enhancing economic benefit.
