| 摘 要： | 对江苏沿海地区（强）热带风暴条件下农田林网防止水稻倒伏和减产效应的研究表明，有林网农田的水稻倒伏率为１６．２８％，无林网农田为４９．７３％；水稻在灌浆结实期倒伏以后，千粒重减少１３．２４％，产量减少１４．３２％，有林网农田的水稻倒伏减产率为无林网农田的１／３．主林带林木保存率大于９０％的林网抗倒度最大，水稻倒伏减产率最小．

| Abstract: | Studies on the effect of farmland windbreak on preventing rice lodging and yield reduction under violent tropical storm in coastal regions of Jiangsu show that the percentage of rice lodging on the farmland with and without windbreaks is respectively 16.28% and 49.73%.If rice lodging is happened at the mildy stage,the thousand grains weight and the yield will be decreased by 13.24% and 14.32%,respectively.The yield reduction rate by rice lodging on the farmland with windbreaks is one third of that on the farmland without windbreaks.When the percentage of keeped trees of main windbreak is more than 90%,the resistance to rice lodging is the maximum,and the yield reduction rate from it is the minimum. |
