Effects of Deep Ditch Mulching on Harvesting Time and Yield of Sweet-waxy Maize
In order to extend the consumption cycle of fresh ears and the processing period of sweet-waxy corn enterprises,combined with the local planting habits in Xinzhou,Shanxi,a deep furrow mulching sowing method that integrates film mulching,furrow and ridge cultivation,and wide and narrow row was tested.By comparing it with the most widely used film side sowing,film top sowing,and bare land flat planting in local area,the following conclusions were drawn.Deep furrow film mulching formed a small greenhouse,which could increase the soil temperature by 13.73％-21.88％in April,and the higher accumulated temperature could promote the germination and growth of maize.The dry matter accumulation was significantly higher than that of other treatments in the early stage of maize growth.The final yield had no significant difference from other treatments,but the growth period was significantly shortened.The harvest time of sweet-waxy corn can be 4 to 19 days ahead of the schedule,so as to achieve early sowing and early harvest.
