Abstract:
The effects of plasticfilm mulching and organic matter (chicken manure and wheat bran flakes)on temperature of soil sterilized by solarization to control root-knot nematodes were investigated.The results showed that chicken manure with mulching transparent plasticfilm could significantly boost daily average soil temperature and daily maximum soil temperature at 10,15,20 and 30 cm soil depths，daily average soil temperatures were 40.5，38.5，35.8 and 36℃，daily average temperatures had been enhanced 7.5，6.5，5.4 and 4.7℃ compared with no plasticfilm mulching，they had been enhanced 3.4，3.2，3.0 and 3.0℃ compared with plasticfilm mulching but no organic matter，respectively.And daily maximum soil temperatures were 46.4,43.5,40.3 and 36.4℃，daily maximum temperatures had been enhanced 10.1,9.2,7.9 and 5.8℃ compared with no plasticfilm mulching，they had been enhanced 4.9，6.3，5.8 and 4.2℃ compared with plasticfilm mulching but no organic matter，respectively.At the same time，plasticfilm mulching and organic matter also markedly extend soil daily temperature difference.It concluded that soil sterilized by solarization with organic matter and transparent plasticfilm mulching was promising in increasing soil temperature within 20 cm soil depth in the study area.
