| 摘 要： | 春夏干旱是榆中县旱作区影响胡麻产量的主要限制因素,为了减少土壤水分的无效蒸发、提高土壤含水量、改善胡麻生长环境和提高胡麻产量,开展了旱地微垄地膜覆盖沟播栽培对土壤水分和胡麻产量的试验研究。结果表明,旱地胡麻微垄地膜覆盖沟播栽培减少了胡麻生长期间土壤水分的无效蒸发,胡麻生长期平均土壤含水量提高,胡麻的出苗率提高,胡麻有效分枝数、全株蒴果数、单蒴果粒数、千粒重等经济性状明显改善;旱地胡麻微垄地膜覆盖沟播栽培比露地栽培增产634.2kg/hm2,产值提高4 439.4元/hm2,纯收入增加3 149.4元/hm2。

| Abstract: | As drought in spring and summer is the main constraint factor influencing flax yield in dry farming area in Yuzhong,experimental studies related to plastic-film mulching on micro-ridges and planting in catchment furrows technique(PMT) were implemented with the objectives of reduction of ineffective soil moisture evaporation and improvement of soil water content,growth environment and yield.The result indicated that PMT reduced ineffective soil moisture evaporation,increased average soil water content during... |
