摘要
本研究设置裸地(CK)、拱棚覆盖(处理1)和覆膜(处理2)3个处理,分析了不同覆盖条件下土壤水热环境的变化及对水果玉米出苗率、株高、产量、经济效益的影响。结果表明:与CK相比,处理1和处理2具有较好的抗寒增温保水作用,出苗率分别提高24.49个百分点和23.23个百分点,最终株高分别增加85.97 cm和83.97 cm,经济效益分别增加38 750元/hm2和36 250元/hm2,净利润分别增加27 700元/hm2和35 500元/hm2。综上,处理1和处理2对早播水果玉米出苗、生长都有保护和促进作用,可使水果玉米上市时间提前,增加经济效益;但是因处理1成本较高,故净利润以处理2最高。
This study set up three treatments,including bare land(CK),arch shed covering(treatment 1) andplastic film covering(treatment 2),to analyze the changes in soil water and heat environment under different coveringconditions and their effects on the emergence rate,plant height,yield and economic benefits of fruit corn.The resultsshowed that compared with CK,treatment 1 and treatment 2 had better cold resistance,temperature increase and waterretention effects.Compared with CK,the emergence rate of treatment 1 and treatment 2 increased by 24.49 percentagepoints and 23.23 percentage points respectively,the final plant height increased by 85.97 cm and 83.97 cm respectively,the economic benefits increased by 38 750 yuan/hm2and 36 250 yuan/hm2respectively,and the net profit increased by27 700 yuan/hm2and 35 500 yuan/hm2respectively.In conclusion,treatment 1 and treatment 2 had protective andpromoting effects on the emergence and growth of early sowing fruit corn,which could advance the market time of fruitcorn and increase economic benefits;however,due to the high cost of treatment 1,treatment 2 had the highest net profit.
