双膜西瓜育苗及移栽的农业气象指标研究

Study on Agrometeorological Index of Double Film Growing and Transplanting of Citrullus lanatus

为进一步提高西瓜的产量和质量,了解不同育苗温度下的最适移栽日期,细化西瓜适宜移栽期的农业气象指标,进行了西瓜育苗及移栽试验。结果显示:最早适宜移栽的日期为3月1日—3月9日,最安全的移栽的日期为3月10日—3月15日;移栽的气象指标为:棚内气温不低于-2.0℃,棚内膜下5 cm地温不低于5℃。

In order to further improve the yield and quality of Citrullus lanatus,to know the optimum transplanting date under different growing temperatures,to refine the agrometeorological indexes of Citrullus lanatus transplanting period,Citrullus lanatus seedling cultivation and transplanting experiments were carried out.The results showed that the earliest suitable transplanting date was from March 1 to March 9,and the safest transplanting date was from March 10 to March 15.The meteorological index of transplanting is:the temperature in the shed is not lower than-2.0℃,and the temperature in 5 cm under the inner membrane of the shed is not lower than 5℃.
