| Abstract: |
| Tests of mulching with film of different kinds of materials were carried out after flat sowing peanut using watershed microplot. The results indicate that the soil temperature in the field covered by Liquid Microbe Degradable Film(LMDF) increased significantly, by an average of 0.2℃~1.1℃ on flowering and pegging stage and 0.1℃~1.7℃ on pod setting stage
during the whole day. It was beneficial to peanut because of the better heat preservation. Fiber Black Resin Film(FRF) and Powder Degradable Film(PDF) had similar and relatively poor effect on surface soil temperature preservation. Polyethylene
Plastic Film(PPF) had always kept a high soil temperature during the growing period. There were obvious differences between PPF and LMDF in soil temperature preservation, but they
were both sig-nifieantly higher than that of no mulching treatment(CK). The Pn in LMDF and PPF mulching increased respectively by 21%and 17%, and Tr in LMDF and PPF mulching increased respectively by 52% and 15%. Therefore, LMDF and PPF are more conducive to peanut production, and LMDF is suitable to mulching on peanut. |
