Abstract: |
In Huining county, Gansu province, Longmi 5 was used as the indicator cultivar to study the effects of water-permeable plastic film mulching, common plastic film mulching and no mulching on soil moisture and temperature, growth and development of broomcornmillet. The result showed that water-permeable plastic film with moisture permeable function was more effective on the water retention than common plastic film. However, micropore evaporation of the water-permeable plastic film caused moisture content slightly lower than that of the common plastic film at 0~20 cm soil layer. Compared with open ground, water-permeable plastic film and common plastic film had obvious effects on heat insulation and temperature increasing, which significantly increased broomcorn millet yield by 46.79% and 67.13%, respectively. However, there was no significant difference in yield between plastic film mulching modes. |
