山西省高寒区枣树设施栽培升温保温技术研究

Study on the Technology of Rising Temperature and Insulation of Jujube Facility Cultivation in Colder Area of Shanxi

笔者在大同市云州区桦林背林场,对山西省高寒区枣树设施栽培的升温保温技术进行了研究。筛选出了山西省高寒区砖墙结构日光温室地面复合覆盖(至下而上)土壤升温保温关键技术2种,分别为10 cm草层+菌肥(与草混合)+地膜和10 cm草层+地膜。这2种技术只能用在2月上旬升温的模式之中,使成熟期提前20 d^30 d.棚膜+棉被+地膜模式能使萌芽期提前至2月8日,成熟期提前到6月至7月,应根据栽培模式选择配套措施。

Technology of rising temperature and insulation of jujube facility cultivation in colder area of Shanxi was studied in Hualinbei forest farm in Yunzhou District of Datong.Two key technologies of soil rising temperature and insulation which was ground composite coverage(from bottom to top)in solar greenhouse with brick wall structure were selected.The two technologies were 10 cm grass layer+bacterial manure(mixed with grass)+plastic film and 10 cm grass layer+plastic film.The two techniques could only be used in the pattern of rising temperature in early February,and the maturity period was 20 d^30 d earlier.The facility cultivation mode of shed film+quilt+mulching film could advance the germination period to February 8th,and could advance the maturity period to June or July.The matching measures should be selected according to the cultivation mode.
