Abstract: |
The purpose of this study is to investigate potato growth, yield, quality and economic benefit for different cover and ridge tillage planting in the dry land. Dingshu#4 was selected as material, six treatments were carried out in the field experiment, including whole film coating planting with black film double ridges (A), whole film coating planting with white membrane double ridges (B), the single ridge with black film coated planting (C), the single ridge with white film coated planting (D), grass planting for control (E), and bare land (CK). The results showed that emergence rate was increased by 5.7%~11.6%, plant height by 1.2~10.5 cm, plant spreading by 11.1%~42.1% in different mulching treatment. The number of tuber per plant was increased by 0.61~2.82, the tuber weight per plant by 3.2%~15.6%, big potato ratio by 0.02%~0.02%, small potato weight by 4.5%~4.5%, yield by 11.5%~31.2%, commodity potato rate by 1.82%~3.06%. There was no significant difference for crude starch content in B, D and E compared with control. The crude protein content in different coverage was decreased by 3.83%~9.36% than control. |
