Abstract: [Objective]The effect of different soil surface mulching on processing tomato seeds in high temperature condition was studied in this paper.[Method]The results showed that the light ratio respectively decreased to 25.97 ; and 20.15 ; by using black films and transparent film +75; shading net,the average temperature of mulched soil was always lower than 30 ℃ in daytime during germination process; after sowing six days,the seed dry matters respectively consumed to 81.85 ; and 86.16 ;,and the seeds germination reached normal level,the germination rate was 91; and 87; respectively.

摘要： [目的]提高新疆加工番茄在延长其播种期的种子发芽率.[方法]研究了在水分充足的高温条件下采用不同覆盖处理对加工番茄种子发芽的影响.[结果]黑色薄膜和透明薄膜+75;遮阳网覆盖处理可使日光透光率降至25.97;和20.15;;种子发芽过程中白天膜下土壤平均温度始终低于30℃,播种后6 d,黑色薄膜和透明薄膜+75;遮阳网覆盖处理的种子干物质消耗分别为81.85;和86.16;,种子发芽率分别为91;和87;,达到正常水平.[结论]采用黑色薄膜或透明薄膜+75;遮阳网的覆盖模式都能有效降低膜下地温,可以作为延期时播种提高加工番茄种子发芽率的措施.
