不同地膜覆盖对地温和杂交谷生长发育的影响
Effect of different plastic mulching on soil temperature and growing development on hybrid millet
摘要
Abstract
[Objective]In order to study the effect of different plastic film mulching on the relationship between ground temperature and hybrid valley .[Methods]This experiment conducted 5 treatments of bare ground ,white/black ordina-ry film and white/black degradable film based on Zhangzagu 10 .[Results]The results showed that at the early growth stage ,the average temperature at 10~20 cm were improved around 6 ℃ and 4 ℃ under white/black film treatment , the warming effect was weakened at the late growth stage .Black film could avoid high temperature stress to a certain extent .There were smaller difference in daily temperature under deeper soil layer ,the difference between the treat-ments was not significant .SPAD value of plastic film treatment was higher than bare land .Pn under white normal/de-gradable plastic film treatments were 5.17 and 5.46 μmol·m -2 ·s-1 significantly higher than CK .WUE was signifi-cantly improved under black film treatment ,ordinary/degradable plastic film were 7.78% ,7.05% higher than CK . The plant height under film mulching treatments were earlier about 7~10 days reached the maximum value than CK . The yield under black film treatment was significant increased ,and black degradable plastic film had the highest yield , which was 9713.3 kg·hm -2 .[Conclusion]Compared with ordinary plastic film ,degradable plastic film gradually de-composed in the late growth stage ,and the residue in the soil was small .This study showed that it was feasible to re-place ordinary plastic film with degradable plastic film in the production of Zhangzagu .关键词
