Abstract
Crop residues may be used to control soil borne plant diseases. In a laboratory experiment, the effects of different rates of wheat straw on soil physical properties and Phytophthora capsici population were studied under different flooding time. The impact of wheat straw with flooding on the growth and yield of chili pepper was carried out in high tunnel fields. Compared to moist soil, applying wheat straw and flooding significantly decreased soil EC but increased organic matter, available phosphorus, available potassium, organic acids and phenolic acid contents. The number of P. capsici was reduced significantly in both flooding only and flooding plus wheat straw in comparison with the moist soil. Application of 0.25% wheat straw with flooding for 10 days or 14 days strongly inhibited the growth of P. capsici. However, such inhibition to P. capsici declined with increasing rates of wheat straw. Field tests showed that flooding for 20 days with wheat straw addition at400 kg/667 m2 not only increased contents of ammonium nitrogen, available phosphorus and available potassium but also effectively reduced disease incidence of chili pepper blight, promoting pepper growth and enhancing chili pepper yield by 12%.
