Application Effect Evaluation of PE Mulch with Different Thickness on Spring Peanut
摘要
Abstract
To investigate the application effect of PE mulch with different thicknesses on spring peanuts,the soil temperature,moisture,residual film recovery and growth of spring peanut with four different thicknesses of PE mulch(0.004,0.008,0.010,0.015 mm)were studied,and the non-mulching treatment was used as the control.The result showed that the average temperatures of the soil 10 cm under the mulch were increased by 1.41-2.58℃,and the accumulated temperature of peanut during the growth period was increased effectively.Compared with the non-mulching treatment,the peanut yield increased by 8.78%-9.92%with the 0.004-0.01 mm mulch treatments,while the peanut yield with the 0.015 mm mulch treatment decreased by 6.20%.The total pod number covered with 0.004-0.01 mm plastic film were about 120 per hole,which were significantly higher than those of the non-mulching treatment and 0.015 mm mulch treatment.Compared with 0.004 mm mulch treatment,the proportion of effective needles of 0.008,0.01,and 0.015 mm mulch treatments decreased by 9.97%,11.51%and 25.49%,while the full fruit rate increased from 46.38%to 65.52%.Standard mulch has a certain impact on peanut needles,and measures such as increasing the hole diameter of the membrane rupture and improving the quality of soil covering the seed row on the film can be taken to promote peanut needles.Application of standard mulch improves the recyclability of waste mulch.Peanuts are harvested by excavating strip-laying harvesters,and more than 90%of the mulch film can be carried away from the field by peanut straw.Then the mulch removal kneading machine can be used to separate the mulch from peanut straw and realize the recycling and utilization of mulch and peanut straw.关键词
