| Abstract: |
| In order to select the optimal mulching method in the dryland farming of northern Shaanxi Loess Hilly Region, we studied the effects of straw mulching and plastic film mulching on yield and water use efficiency (WUE) of Potato. Through 2 years of fixed field experiment (from 2012 to 2013), we adopted five mulching methods which included ridge mulching(LM), double channels mulching(GM), double ridge mulching(QM), straw mulching(JG) and bare land (CK), and analysed the changes of the growth, yield, soil temperature and moisture of potato. The results showed that: (1) Under the treatment of JG, growth and development status, plant height and the SPAD value of potato were superior to others which showed JG>CK>GM>LM>QM for plant height, LM>GM>CK>JG>QM for stem thickness and JG>LM>GM>CK>QM for SPAD value; (2) In the whole growth period, soil temperature showed JGQM>GM>LM>CK, the soil moisture in the treatment of JG, LM, GM and QM were 17.18%, 11.92%, 5.65% and 16.93% higher than that in the CK, respectively; (4) The yield in the treatment of JG, QM, LM and GM were 19.75%, 8.95%, 7.00% and -0.25% higher than that in the CK, respectively, and the WUE were 16.4%, 7.4%, 9.15% and 1.65% higher than that in the CK, respectively. Straw mulching was selected as the best dryland farming cultivation method in the dryland farming of northern Shaanxi loess hilly region. |
