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。

Abstract: | his study set the CK respectively (bare land), treatment 1 (tunnel) and 2 (coated) three processing, thermal environment analysis of soil water fruit corn seedling emergence, plant height, yield and economic benefit.The results show that compared with treatment 1 and treatment 2 CK has good cold resistance heating in water;Treatment 1 and treatment 2 emergence rate respectively were 24.49% and 23.23% higher than CK, the final plant height were higher than CK 35.86 cm and 36.40 cm, economic benefits were higher than CK, hm - 2 and 35500 yuan, 27700 yuan hm - 2.In conclusion, treatment 1 and 2 are in earlier planting fruit corn, have protection on crop emergence, growth and promote role, time to market ahead of time, improve the economic benefit. 1 economic cost is higher, but the processing eventually deal with 2 have the highest net profit. |
