Title: Effects ofstraw organic materials manuring on soil physical and chemical properties and rice yield of paddy field
Abstract: The 2-year location tests for straw organic materials to be added to paddy fields were carried out on the Chongming Island to study the effects on the soil physical and chemical properties and rice yield.The results showed that manuring of several straw organic materials and combined application of chemical fertilizers was conducive to improvement of soil nutrients such as organic matter,N,P,K,readily available N and available P as well as increasing of the R_(0.25),mean weight diameter and geometric mean diameter of soil aggregates;It somewhat decreased the rice yield but improved the comprehensive economic benefit,being 276.61- 1457.22 yuan/hm~2 higher than the conventional fertilization,and the gain rate of biogas residue manuring was up to 11.83%.
